Description:
BACKGROUND  
         [0001]    1. Field  
           [0002]    The present application relates to a method and apparatus for data communications, and more particularly to a method and apparatus for data communications capable of automatically sending a maintenance request.  
           [0003]    2. Description of the Background Arts  
           [0004]    Image forming devices including copying machines, facsimile machine, printers, and also multi function devices made by combining such machines can receive maintenance services from a service depot. When an apparatus has a component which is defective or a consumable product whose life ends or is about to end, a user sends a request to a service depot for a repair service or a delivery of the consumable product.  
           [0005]    For example, a Published Japanese Unexamined Patent Application, No. 2-51968 (1990), discusses an apparatus capable of registering a list of consumable products in use and sending a facsimile message to a designated service depot when one of the consumable products need replacement so as to receive a delivery of the necessary consumable product from the service depot.  
           [0006]    As another example, a Japanese Patent, No. 2744768, discusses an image forming apparatus capable of sending a facsimile message to a designated service depot of a problem that has occurred in the apparatus.  
           [0007]    As another example, a Published Japanese Unexamined Patent Application, No. 10-207304, discusses a facsimile machine capable of handling E-mail communications through the Internet and using E-mail to communicate with a service depot for a request of various services.  
           [0008]    However, in the above proposals, the request for the various services is directly sent to the service depot without notifying a manager or administrator who supervises equipment used in an office, including the above conventional devices. As a result, the manager may not have knowledge about services requested of or provided by the service depot.  
         SUMMARY  
         [0009]    The present application describes a novel data terminal apparatus. In one example, a novel data terminal apparatus includes a communications mechanism, a detector, a register, and a controller. The communications mechanism is configured to perform electronic communications with a manager supervising the apparatus. The detector detects a status of usage of a consumable product used in the apparatus and supplied by a service depot. The register registers electronic communications addresses of the manager and the service depot, identification of the apparatus, specification of the consumable product, and identification of the service depot. The controller is configured to send a request for supplying the consumable product to the manager using the electronic communications address when the detector detects that the consumable product needs or soon needs replacement or replenishment. At this time, the request includes the identification of the apparatus, the specification of the consumable product, and the identification of the service depot. Further, the controller is configured to send a report for reporting a completion of supplying the consumable product on the apparatus when the detector detects that the consumable product is refilled.  
           [0010]    The communications mechanism may perform E-mail communications with the manager.  
           [0011]    The consumable product may include toner.  
           [0012]    The communications mechanism may perform facsimile communications with the manager.  
           [0013]    The present application further describes a novel data terminal apparatus. In one example, a novel data terminal apparatus includes a communications mechanism, a detector, a register, and a controller. The communications mechanism is configured to perform electronic communications with a manager supervising the apparatus and a service depot providing a repair service to the apparatus. The detector detects an event that a maintenance component used in the apparatus is defective or at the end of its useful life. The register registers electronic communications addresses of the manager and the service depot, identification of the apparatus, and information of the event, and identification of the service depot. The controller is configured to send a request for the repair service to the manager and the service depot using the respectively registered electronic communications addresses when the detector detects the event. At this time, the request includes the identification of the apparatus, the specification of the maintenance component, and the identification of the service depot. Further, the controller sends a report for reporting a completion of the repair service on the apparatus when the detector detects no defect of the maintenance component.  
           [0014]    The communications mechanism may perform E-mail communications with the manager and the service depot.  
           [0015]    The maintenance component may include a photoconductor.  
           [0016]    The communications mechanism may perform facsimile communications with the manager and the service depot.  
           [0017]    Further, the present application describes a novel method of ordering a consumable product of a communications terminal apparatus. In one example, a novel method includes the steps of registering, detecting, sending, determining, and reporting. The registering step registers electronic communications addresses of a manager supervising the apparatus and a service depot supplying the consumable product, identification of the apparatus, specification of the consumable product, and identification of the service depot. If the detecting step detects that a consumable product needs replacement/replenishment, the sending step sends a request for supplying the consumable product to the manager using the electronic communications address, the request including the identification of the apparatus, the specification of the consumable product, and the identification of the service depot. The determining step determines that the consumable product has been supplied to the apparatus. The reporting step reports to the manager a completion of supplying the consumable product on the apparatus.  
           [0018]    The sending and reporting steps may perform E-mail communications with the manager.  
           [0019]    The consumable product may include toner.  
           [0020]    The communications mechanism may perform facsimile communications with the manager.  
           [0021]    Further, the present application describes a method of ordering a repair service for a communications terminal apparatus. In one example, a novel method includes the steps of registering, detecting, sending, determining, and reporting. The registering step registers electronic communications addresses of a manager supervising the apparatus and a service depot providing a repair service, identification of the apparatus, specification of a maintenance component, and identification of the service depot. If the detecting step detects that a maintenance component is defective, or needs replacement, the sending step sends a request for the repair service to the manager and the service depot using the respectively registered electronic communications addresses, the request including the identification of the apparatus, the specification of the maintenance component, and the identification of the service depot. The determining step determines that the maintenance component is not defective. The reporting step reports to the manager a completion of performing the repair service on the apparatus.

     DETAILED DESCRIPTION  
       [0033]    In describing preferred embodiments illustrated in the drawings, specific terminology is employed for the sake of clarity. However, the invention is not intended to be limited to the specific terminology so selected and it is to be understood that each specific element includes all technical equivalents which operate in a similar manner.  
         [0034]    Referring now to the drawings, wherein like reference numeral designate identical or corresponding parts throughout the several views, particularly to FIG. 1, an Internet facsimile apparatus  1  according to an embodiment of the present application is described. The Internet facsimile apparatus  1  of FIG. 1 includes a facsimile main controller  2 , a registration unit  3 , a consumable product status detector  4 , a maintenance status detector  5 , a facsimile communications controller  6 , a PSTN (public switched telephone network) controller  7 , an E-mail data generator  8 , a LAN (local area network) controller  9 , an E-mail data analyzer  10 , and an E-mail controller  11 . These components are connected with each other via a data bus  19 .  
         [0035]    The LAN controller  9  of the Internet facsimile apparatus  1  is connected to a PC (personal computer)  13  used by a manager of an office via a LAN (local area network)  12  which services the office and is connected to the Internet  14 . The Internet  14  is connected to a service depot system  16  via another LAN (local area network)  15 . The service depot system  16  is also connected to the PSTN controller  7  of the Internet facsimile apparatus  1  via a PSTN (public switched telephone network)  17 .  
         [0036]    In the preferred embodiment, a communications system is established in which the Internet facsimile apparatus  1  can communicate with the PC  13  by exchanging E-mail via a mail server (not shown) hooked on the LAN  12  and with the service depot system  16  by exchanging E-mail via the LAN  12  and a facsimile message via the PSTN  17 .  
         [0037]    The Internet facsimile apparatus  1 , the PC  13 , and the service depot system  16  exchange E-mail each other through transmission using a SMTP (simple mail transfer protocol) and a POP3 (post office protocol version 3) via mail servers provided to the LANs  12  and  15 .  
         [0038]    More than one unit of the PC  13  may be connected to the LAN  12  so that use of the Internet facsimile apparatus  1  may be managed by the plurality of the PC  13 , for example, when two or more managers (administrators) are involved.  
         [0039]    As shown in FIG. 2, the facsimile main controller  2  of the Internet facsimile apparatus  1  includes a CPU (central processing unit)  21 , a ROM (read only memory)  22 , a RAM (random access memory)  23 , a DCR (data compression and decompression) unit  24 , a scanner  25 , a printer  26 , an image memory  27 , and an operation panel  28 . The CPU  21  controls the entire operations of the Internet facsimile apparatus  1 , including a sequential facsimile operation, operations for notifying a request for replenishing a consumable product such as toner and a request for performing maintenance of resources such as a heater, E-mail operations for notifying a toner refilling request and a service maintenance request, and so forth.  
         [0040]    The ROM  22  stores various control programs performed by the CPU  21 . For example, programs of a toner refill request notification, a heater service maintenance notification, a toner refill completion notification, and a heater service maintenance completion notification are stored in the ROM  22 .  
         [0041]    The RAM  23  temporarily stores various kinds of data necessary for the CPU  21  when it performs the above-mentioned control programs and reserves a working memory area for the CPU  21 .  
         [0042]    The DCR  24  compresses, or encodes, image information when the information is transmitted and decompresses, or decodes, encoded image information when the information is received. Thereby, the time for transmission and receiving of image information is shortened in an efficient manner.  
         [0043]    The scanner  25  uses a CCD (charge-coupled device) to serve as an image scanner that scans a document to read image data of the document at a predetermined resolution in accordance with an instruction sent from the CPU  21 .  
         [0044]    The printer  26  records the received image data on a recording sheet in accordance with an electrophotographic method using a photoconductive drum, toner, etc.  
         [0045]    The image memory  27  saves images scanned by the scanner  25  and images received.  
         [0046]    The operation panel  28  includes an LCD (liquid crystal display) and various kinds of operation keys, not shown, including switches for performing various operations during the facsimile transmission, switches for inputting various kinds of information related to E-mail, a display portion for displaying a toner near-end indication when a consumable product such as the toner needs replenishment, a display portion for displaying a heater failure, and so forth.  
         [0047]    As shown in FIG. 3, the registration unit  3  registers various kinds of terminal information regarding the Internet facsimile apparatus  1 , including a serial number, an E-mail address, a facsimile number, and facsimile TTI (transmitter terminal identification) information and serves as a terminal identification information registration means. The registration unit  3  further registers a mail address and a telephone number of the PC  13  used by the manager and serves as a manager registration means. The registration unit  3  further registers a mail address and a telephone number of the service depot system  16 , to which the order for the consumable products such as toner is directed, and serves as a service depot registration means.  
         [0048]    In addition, the registration unit  3  registers consumable product information, including toner ordering information that includes a type of toner, service contents, status information such as a toner near-end, in association with the service depot system  16  and serves as a consumable product information registration means.  
         [0049]    The consumable product status detector  4  includes a toner amount detection sensor (not shown) which detects a remaining amount of toner and sends a signal to the facsimile main controller  2 . The consumable product status detector  4  serves as a consumable product status detecting means.  
         [0050]    The maintenance status detector  5  detects a status of a maintenance-needed resource such as a heater that heats a fixing roller (not shown) for fixing a toner image on a recording sheet and, for this purpose, includes a sensor (not shown) for detecting a voltage value of the heater and sends a signal to the facsimile main controller  2  when the voltage value is not maintained within a predetermined range. The maintenance status detector  5  serves as a maintenance detecting means.  
         [0051]    The facsimile communications controller  6  executes Group  3  protocols to perform Group  3  facsimile communications.  
         [0052]    The PSTN controller  7  connects the Internet facsimile apparatus  1  to the PSTN  17  and includes functions for automatically transmitting and receiving facsimile information.  
         [0053]    The E-mail data generator  8  generates E-mail data based on various kinds of information and arbitrary repetitive documents registered in the registration unit  3  or data read from a document by the scanner  25 .  
         [0054]    The LAN controller  9  connects the Internet facsimile apparatus  1  to the LAN  12  so as to perform communications protocols to communicate with the PC  13  or with the service depot system  16 .  
         [0055]    The E-mail analyzer  10  analyzes E-mail received through the LAN  12  and serves as an analyzing means. In this example, the E-mail analyzer  10  analyzes E-mail with respect particularly to receipt acknowledgements to an order of a consumable product received from the service depot system  16  and to a request for a service maintenance received from the PC  13  or the service depot system  16 .  
         [0056]    The E-mail controller  11  transmits E-mail that is generated by the E-mail data generator  8  and provides information about a consumable product and/or maintenance of resource to the mail server through the SMTP via the LAN controller  9 .  
         [0057]    In the thus-configured Internet facsimile apparatus  1 , the facsimile main controller  2  instructs the E-mail data generator  8  to generate E-mail for ordering a consumable product and the E-mail controller  11  to transmit the E-mail to the manager registered in the registration unit  3  when detecting an event such as that the toner needs to be replenished based on detection information from the consumable product status detector  4 . In this case, the E-mail includes the terminal information, order contents, and information of a seller of the toner products such as the service depot system  16 . Further, the facsimile main controller  2  instructs the E-mail data generator  8  to generate E-mail for notifying of completion of toner refilling and instructs the E-mail controller  11  to transmit the E-mail to the manager upon detecting that toner refilling is completed based on the detection information detected by the consumable product status detector  4 .  
         [0058]    Further, the facsimile main controller  2  instructs the E-mail data generator  8  to generate E-mail for requesting service maintenance and instructs the E-mail controller  11  to transmit the E-mail to the manager and to the service depot system  16 , both registered in the registration unit  3 , upon detecting that the heater is in need of service maintenance based on the detection information detected by the maintenance status detector  5 . In this case, the E-mail includes the terminal information and information about the needed maintenance. Further, the facsimile main controller  2  instructs the E-mail data generator  8  to generate E-mail for notifying of completion of the heater maintenance and the E-mail controller  11  to transmit the E-mail to the manager upon detecting that the heater maintenance is completed based on the detection information detected by the maintenance status detector  5 .  
         [0059]    In this example, the facsimile main controller  2 , the E-mail data generator  8 , and the E-mail controller form an E-mail controlling means.  
         [0060]    The facsimile main controller  2  displays through the operation panel  28  the receipt acknowledgements of an order for a consumable product and of a request for a service maintenance, analyzed by the E-mail data analyzer  10 . Further, the facsimile main controller  2  stops displaying the receipt acknowledgements through the operation panel  28  upon detecting that the toner fulfilling is completed based on the detection information detected by the consumable product status detector  4  or that the heater maintenance is completed based on the detection information detected by the maintenance status detector  5 . Thus, the facsimile main controller  2  forms a displaying means.  
         [0061]    Further, the facsimile main controller  2  provides the above-mentioned notification to the facsimile number registered in the registration unit  3  through the facsimile communications, instead of E-mail, when the manager or the service depot system  16  is not capable of using E-mail.  
         [0062]    Referring to FIGS.  3 - 8 B, an exemplary procedure related to the toner refilling is explained. FIG. 4 shows a flowchart of a procedure for ordering toner refilling and a procedure for ordering heater maintenance. The latter will be explained later. In Step S 1 , the facsimile main controller  2  finds an event by counting a predetermined number of pages printed or hours in operation and, in Step S 2 , checks if the consumable product status detector  4  has detected an event related to need for toner replenishing or if the maintenance status detector  5  has detected an event related to a need for heater maintenance. If the consumable product status detector  4  detects an event related to need for toner and the check result of Step S 2  indicates that the need is for a consumable product, the facsimile main controller  2  determines that the remaining amount of toner is at a near end status and displays the event of the toner near end through the operation panel  28 .  
         [0063]    In Step S 3 , the facsimile main controller  2  determines if the information necessary for the transmission of E-mail, such as the terminal information, the manager information, and the service depot information, shown in FIG. 3, is registered in the registration unit  3 . If the terminal information of the Internet facsimile apparatus  1 , the manager information of the PC  13 , and the service depot information of the service depot system  16  are determined as registered in the registration unit  3  and the check result of Step S 3  is YES, the process proceeds to Step S 4  in which the notification of the toner shortage and the toner ordering is sent to the manager. More specifically, in Step S 4 , the E-mail data generator  8  generates E-mail in a form such as shown in FIG. 6A, the E-mail controller  11  executes the mail transmission operation, and the LAN controller  9  transmits the E-mail to the mail server through the SMTP procedure via the LAN  12 . This E-mail is transmitted to the PC  13  on the LAN  12 .  
         [0064]    The E-mail of FIG. 6A is an order sheet for ordering a supply of toner, indicating information of a mail address of the service depot system, information of the consumable product including a status of the remaining toner and the name of the product, and information of the sender including an E-mail address of the Internet facsimile apparatus  1  of the user, a serial number, and the name of the sender.  
         [0065]    In Step S 5 , information according to the contents of the E-mail of FIG. 6A is displayed in a form such as shown in FIG. 6B on the LCD of the operation panel  28  after completion of the transmission of the E-mail. Then, the process ends.  
         [0066]    From the above E-mail, the manager understands that toner type  2  is in short supply at the Internet facsimile apparatus  1  of the sales department. Therefore, if the toner is in stock, the manager sends the toner to the Internet facsimile apparatus  1  and if no toner is in stock, the manager transmits the E-mail to the service depot system  16  via the Internet  14 .  
         [0067]    Upon receipt of the E-mail, the service depot system  16  specifies the Internet facsimile apparatus  1  of the user and the requisite toner product from the contents of the E-mail and subsequently sends E-mail indicating a toner delivery schedule, as shown in FIG. 7A, to the user at the Internet facsimile apparatus  1  and the manager at the PC  13  via the Internet  14 . At this time, the contents of the E-mail are displayed on the LCD displays in a form such as shown in FIG. 7B.  
         [0068]    An operation of the Internet facsimile apparatus  1  at receipt of the E-mail from the service depot system  16  is explained with reference to the flowchart of FIG. 5. In Step S 10 , the Internet facsimile  1  receives the E-mail of FIG. 7A from the service depot system  16 . In Step S 11 , the facsimile main controller checks if the status indicates either that the consumable product is in short supply or that the service maintenance is in need, or not. If, in this case, the status indicates that the consumable product is in short and the check result of Step S 11  is YES, the facsimile main controller  2  determines in Step S 12  if the sender of the E-mail is one of the manager and the service depot system  16 .  
         [0069]    Then, the E-mail data analyzer  10  analyzes the contents of the E-mail sent from the service depot system  16  and, if the address of the E-mail sender is determined as identical to the address of the service depot system  16 , the facsimile main controller  2  determines that the E-mail was sent from the service depot system  16 . In this case, the facsimile main controller  2  displays in Step S 13  the text message of the E-mail as is, which is considered as corresponding to the receipt acknowledgement information sent from the service depot system  16 . The display is through the LCD of the operation panel  28 , such as shown in FIG. 7B.  
         [0070]    The user of the Internet facsimile apparatus  1  sees on the display the message indicating that the toner is to be delivered on 30 th  of August and will refill the toner when it is delivered on 30 th  of August. After the toner refilling, the consumable product status detector  4  detects an event related to an indication that the toner refilling is completed. Then, in the Internet facsimile apparatus  1 , the facsimile main controller  2  performs the operations of Steps S 1 -S 3  FIG. 4 in the manners similar to those described above. But, in Step S 4 , the E-mail data generator  8  generates E-mail having a message that indicates the toner refilling has been completed, such as shown in FIG. 8A, to the manager registered in the registration unit  3 . After transmission of the E-mail to the manager with the E-mail controller  11 , the facsimile main controller  2  displays in Step S 5  a message through the LCD indicating that the toner refilling has been completed, such as shown in FIG. 8B.  
         [0071]    Consequently, from the information contained in the E-mail of FIG. 8A, such as the sender information, the serial number, and the E-mail address, the manager can confirm that the toner refilling has been completed at the Internet facsimile apparatus  1 . At this time, the receipt acknowledgement information indicated through the LCD, such as shown in FIG. 8B, is discontinued.  
         [0072]    Referring to FIGS.  3 - 5 , and  9 A- 11 B, an exemplary procedure with respect to heater maintenance is explained. In Step S 1  of FIG. 4, the facsimile main controller  2  finds an event by counting a predetermined number of pages printed or hours in operation and, in Step S 2 , checks if the maintenance status detector  5  has detected an event indicating that the toner is in short supply or if the maintenance status detector  5  has detected an event indicating that the heater is in need of maintenance. If the maintenance status detector  5  has detected an event indicating that the heater is in need of maintenance and the check result of Step S 2  indicates a need for maintenance, the facsimile main controller  2  determines that the heater is in a defective status and displays this status through the operation panel  28 .  
         [0073]    In Step S 6 , the facsimile main controller  2  determines if the information necessary for the transmission of E-mail, such as the terminal information, the manager information, and the service depot information, shown in FIG. 3, is registered in the registration unit  3 . If the terminal information of the Internet facsimile apparatus  1 , the manager information of the PC  13 , and the service depot information of the service depot system  16  are determined as registered in the registration unit  3  and the check result of Step S 6  is YES, the process proceeds to Step S 7  in which the notification of the heater defect and the maintenance ordering is sent to the manager. More specifically, in Step S 7 , the E-mail data generator  8  generates E-mail in a form such as shown in FIG. 9A, the E-mail controller  11  executes the mail transmission operation, and the LAN controller  9  transmits the E-mail to the mail server through the SMTP procedure via the LAN  12 . This E-mail is transmitted to the PC  13  on the LAN  12 .  
         [0074]    The E-mail of FIG. 9A is an order sheet for ordering service maintenance, indicating information of a mail address of the service depot system  16 , information of the service maintenance including a status of the machine and an error code, and information of the sender including an E-mail address of the Internet facsimile apparatus  1  of the user, a serial number, and the name of the sender.  
         [0075]    In Step S 8 , information according to the contents of the E-mail of FIG. 9A is displayed in a form such as shown in FIG. 9B, through the LCD of the operation panel  28  after completion of the transmission of the E-mail. Then, the process ends.  
         [0076]    From the above E-mail, the manager understands that the heater is defective on the Internet facsimile apparatus  1  of the sales department and that the E-mail is also transmitted to the service depot system  16 .  
         [0077]    Upon a receipt of the E-mail, the service depot system  16  specifies the Internet facsimile apparatus  1  of the user and the requisite components for repair based on the contents of the E-mail and subsequently sends E-mail indicating a repair schedule, such as shown in FIG. 10A, to the user at the Internet facsimile apparatus  1  and the manager at the PC  13  via the Internet  14 .  
         [0078]    An operation of the Internet facsimile apparatus  1  at receipt of the E-mail from the service depot system  16  is explained with reference to the flowchart of FIG. 5. In Step S 10 , the Internet facsimile  1  receives the E-mail of FIG. 10A from the service depot system  16 . In Step S 11 , the facsimile main controller checks whether or not the status indicates either that the consumable product is in short supply or that the service maintenance is in need. If, in this case, the status indicates that service maintenance is needed and the check result of Step S 11  is YES, the facsimile main controller  2  determines in Step S 12  if the sender of the E-mail is one of the manager and the service depot system  16 .  
         [0079]    Then, the E-mail data analyzer  10  analyzes the contents of the E-mail sent from the service depot system  16  and, if the address of the E-mail sender is determined as identical to the address of the service depot system  16 , the facsimile main controller  2  determines that the E-mail was sent from the service depot system  16 . In this case, the facsimile main controller  2  displays in Step S 13  the text message of the E-mail as is, which is considered as corresponding to the receipt acknowledgement information sent from the service depot system  16 , through the LCD of the operation panel  28 , such as shown in FIG. 10B.  
         [0080]    The user of the Internet facsimile apparatus  1  sees on the display the message indicating that the repair is performed on 30 th  of August, such as shown in FIG. 10B. After completion of the heater repair, the maintenance status detector  5  detects an event indicating that the heater repair is completed. Then, in the Internet facsimile apparatus  1 , the facsimile main controller  2  performs the operations of Steps S 1 -S 3  FIG. 4 in a manner similar to that described above. But, in Step S 4 , the E-mail data generator  8  generates E-mail having a message that indicates the heater repair has been completed, such as shown in FIG. 11A, to the manager registered in the registration unit  3 . After transmission of the E-mail to the manager with the E-mail controller  11 , the facsimile main controller  2  displays in Step S 8  a message through the LCD indicating that the heater repair has been completed, such as shown in FIG. 11B.  
         [0081]    Consequently, from the information contained in the E-mail of FIG. 11A, such as the sender information, the serial number, and the E-mail address, the manager can confirm that the heater maintenance has been completed on the Internet facsimile apparatus  1 . At this time, the receipt acknowledgement information indicated with the LCD, such as shown in FIG. 11B, is discontinued.  
         [0082]    Although the notification to the manager and the service depot system is performed with E-mail in this example, the communications may be performed with a facsimile message in an environment where E-mail is not available, which will have the same effect as in the E-mail environment.  
         [0083]    In this example, the facsimile main controller  2  is configured to automatically display the text message of the E-mail sent from the service depot system. In addition, the facsimile main controller  2  may display a text message of the E-mail, sent from the manager, in which the manager explains intermediate status, such as shown in FIG. 12A. In this case, a message may be displayed on the LCD, such as shown in FIG. 12B.  
         [0084]    Although this example uses text information of the E-mail as it is as examples of analysis with respect to formats of E-mail data, any specific format may be used.  
         [0085]    The disclosed processes may be conveniently implemented using a conventional general purpose digital computer programmed according to the teaching of the present specification, as will be apparent to those skilled in the computer art. Appropriate software coding can readily be prepared by skilled programmers based on the teachings of the present disclosure, as will be apparent to those skilled in the software art. The implementation may also, or alternatively, use application specific integrated circuits or an appropriate network of conventional component circuits, as will be readily apparent to those skilled in the art.  
         [0086]    Numerous additional modifications and variations of the present application are possible in light of the above teachings. It is therefore to be understood that within the scope of the appended claims, the present application may be practiced otherwise than as specifically described herein.  
         [0087]    This application claims priority to Japanese patent application No. JPAP2000-133419 filed on May 2, 2000 in the Japanese Patent Office, the entire contents of which are hereby incorporated by reference.
