Title: On-line handwritten character recognizing device
Inventor: ISHIGAKI ICHIJI
IPC: G06K9/62
Filed: 1987-12-19
Abstract: PURPOSE:To suppress the user's distrust of the recognition device by deciding and reporting that a failure in handwritten character input is caused noninclusion in an object of recognition. CONSTITUTION:A 2nd character code input means 12 for KANA (Japanese syllabary) KANJI (Chinese character) conversion is provided for a case wherein a handwriting can not be inputted. A user uses the 2nd character code input means 12 when, for example, KANJI can not be written mainly or when written KANJI can not be recognized, but there is the case wherein a character is not included in the object of recognition. At this time, a recognition object deciding means 13 decides whether a character which is inputted by the 2nd character code input means 12 is the object of recognition or not and an informing means 14 informs the user of the decision result immediately. Consequently, the user's distrust of the device is suppressed.

Abstract: PURPOSE:To attain stable oscillation start even against a wide range of fluctuation of an external power voltage by supplying a small voltage to a MOS transistor(TR) of a MOS transfer gate and a large voltage to an inverter till the oscillation is made stable. CONSTITUTION:During a period from the oscillation start till the stable oscillation reached, a 1st power supply switching circuit 14 selects a 1st voltage division voltage VD1 to supply it to a CMOS transfer gate 4, and a 2nd power supply switching circuit 14 selects a 2nd voltage division voltage VD2 to supply it to a CMOS inverter 3. The 1st voltage division voltage VD1 has a relation of VD1=K1VB, the voltage VD1 is kept low even against a wide range of fluctuation of the power supply voltage VB when the value K1 is set small and the feedback resistance of the CMOS transfer gate 4 is not too small. Moreover, the 2nd voltage division voltage VD2 has a relation of VD2=K2VB, the voltage VD2 is kept high even against a wide range of fluctuation of the power supply voltage VB when the value K2 is set high and the driving capability of the CMOS inverter 3 does not go too low. Thus, the stable oscillation start is attained even against a wide range of the fluctuation of the voltage VB.

Filed: 1998-11-12
Abstract: PROBLEM TO BE SOLVED: To provide a test method and device that can confirm which of segmentation/reassembly functions of an ATM adaptation layer AAL1-cell division assembly SAR function block has a fault. SOLUTION: An AAL1-SAR function block 12 divides data of a digital multiplex channel to generate an ATM cell and the ATM cell is reassembled into data of the digital multiplex line to conduct a wrap test of the AAL1-SAR function. A segmentation counter 103 counts the number of data of the digital multiplex channel from the start of the division to its end, and the number of ATM cells to be generated is calculated from the data number. Furthermore, an ATM cell number generated by the AAL1-SAR function block is counted by a cell counter 104. A comparator 105 compares an ATM cell number to be generated with a generated ATM cell number to examine a division function. A fault location can easily be identified through the wrap test and the division function test.

Title: Freezer apparatus
Inventor: OKA TETSUO
IPC: F25B1/047
Filed: 1992-12-01
Abstract: PURPOSE:To prevent a screw compressor from undergoing a burning failure owing to interruption of injection of a cooling medium without extremely lowering the performance of the screw compressor. CONSTITUTION:There are provided a discharge gas temperature detector 20, an opening adjusting mechanism 30 for a slide valve 4, and a controller 50 for issuing a close instruction signal of closing the valve 4 to a predetermined opening when a calculated slope of discharge gas temperature is higher than a reference slope and further issuing a failure interruption signal when the calculated slope does not get the reference slope after the close instruction signal is issued. The controller 50 lowers the discharge gas temperature by setting the valve 4 to a predetermined opening at a failure where the discharge gas temperature more rapidly rises than in a normal operation owing to cooling interruption of a rotor cooling medium. Further, when the discharge gas temperature is not lowered, the controller 50 renders the compressor 1 to failure interruption to previously prevent contact heating between a gate rotor and a screw rotor from being produced owing to lack of cooling caused by the interruption of the rotor cooling medium for prevention of a baking failure. Lowering of the function of the compressor 1 is reduced by setting the valve 4 to a predetermined opening not to a fully closed state.

Filed: 1997-11-10
Abstract: PROBLEM TO BE SOLVED: To allow a user on the side of a computer to effectively use the entitled facsimile equipment by giving information of the contents of a fault to a computer side through an interface when an operation fault is generated at the facsimile equipment allowing a computer side to utilize a part on all of the functions through the interface. SOLUTION: A system control part 2 confirms the content of the fault presently generated in its own equipment by analysis by a fault monitoring and abnormality analyzing part 12 and collates it with fault contents already registered in a fault managing table to confirm a newly generated fault and a restored fault. When generation and the restoration of the fault is related with a function used on the computer side, a report preparing part 13 prepares a fault (restoration) report and an encoding/decoding part 8 encodes it to give the information to a computer device through an RS232C interface 15. The computer side does not need to have new constitution for content information of an operation fault, therefore it is easy to be realized for various applications.

Title: Multi-processor communication method
Inventor: SUZUKI KATSUYUKI
IPC: G06F15/167
Filed: 1988-12-21
Abstract: PURPOSE:To enable plural subprocessors to perform the well-balanced communication to a main processor by securing the preferential communication to other processors even in case a request is received from a certain process to perform a large quantity of communication and at the same time ensuring the even communication among plural processors. CONSTITUTION:The priority rank is first decided for a subprocessor 2 which produced a request and then it is decided whether the information volume V to be processed is larger than the reference volume VC or not. If so, the entire information volume is not processed but only the prescribed volume of information is processed and the process of the next subprocessor is carried out. Thus the scans are evenly carried out among all subprocessors to prevent a specific subprocessor from being kept waiting for a long time. Furthermore the subprocessors having higher priority ranks are carried out eariler than those of the lower tanks. As a result, the well-balanced communication is secured between all subprocessors 2 and a main processor 1.

Abstract: PURPOSE: To provide a laser beam scanning device capable of easily and always surely obtaining the accuracy of rectilinearity of line scanning without considering the influence to the rectilinearity of line scanning by optical beams on a surface to be inspected due to the difference in parameters of each optical element. CONSTITUTION: When an incidence angle on a plane mirror 3 of a laser beam B emitted from a laser light source 1 is set to be (a), and an inclination angle from a perpendicular line S of a light axis L of a rotary shaft 4 of the plane mirror 3 is set to be (c), the layout positions of each part for a parabolic surface mirror 5 are determined so that (a)≈(c) is established and laser beams BL' and BR' for line scanning can be obtained.  Since a clear standard can be given to the layout of optical elements required for securing the linearity of line scanning on the surface to be inspected by the laser beams BL' and BR', it is not necessary to perform any trial and error layout and adjustment for configuration and the straightness can be always easily and surely suppressed to be within a specific value or less, an accurate inspection can be made by applying to the inspection of surface defect such as film, thus greatly contributing to the quality improvement of a product.
