Abstract: A fax message transmitted by a facsimile transmitter includes bar coded headers in its first page. At least one of these headers contains the name of an addressee that is also a user on a network. A fax server receiving the incoming fax message inspects the first page of the incoming facsimile to locate the bar coded headers. If a TO: header is found it is used to determine the corresponding E-mail address, and the fax is automatically routed as E-mail on the network to the addressee. Any other headers, such as a FROM: or SUBJECT: header have their bar coded content converted to ASCII and attached as ASCII strings to the first page for easy inspection. An asymmetrical nature of the bar code used allows the fax server to determine which of a left-to-right or right-to-left scanning direction produces valid bar code. This in turn indicates whether the headers for the first page are right side up or upside down. By implication, this determines the orientation for the entire fax document. If the document is found to be upside down the fax server erects the document before mailing it to the addressee. The fax server or some other application running on a computer served by the network may be the addressee, and if the incoming fax is a request for information (whether by further bar code or check marks in predefined fields) the information may simply be sent by return fax to the sender, perhaps as part of the same phone call.

Abstract: In a process for manufacturing a rigid-flexible printed circuit (40) wherein a rigid insulating layer (42) supports one portion of the printed circuit and a flexible insulator (44,45) supports another portion thereof to furnish flexible leads for connection the printed circuit to an operative device, a first assembly is provided comprising a curable prepreg insulator layer (100,100') having an opening (102) for the flexible leads. A flexible sheet (104,104') spans the opening, and the assembly is pressed with one surface in contact with a smooth hard surface (112) while the other surface is supported against a flowable durable prepreg layer (108). Between the insulator and flowable layers is a release layer (110,110') which prevents bonding between the prepreg layers throughout most of the areas while permitting bonding along the edges. The assembly is maintained under heat and pressure to partially cure both prepreg layers and bond the flexible sheet to the edges of the opening and bond the edges of the prepregs together to form a flat rigid sandwich. A sheet of copper (116) is bonded to that surface previously in contact with the hard surface, in a second pressing operation, the copper being bonded to both the partially cured prepreg layer and the flexible sheet, and thereafter the bonded edges of the cured prepreg layers, are severed to permit separation of the cured prepreg layers.

Abstract: The In Situ Ionographic Uniformity Correction is a method and apparatus which solves the problem of non-uniform density of ion current projected from an ionographic print head (10) caused chiefly by variations in the dimensions of the modulation channel (24). During calibration, the present invention senses ion current (20) using a simplified ion sensor (36) which has an electrode (32), very large in proportion to the width of several modulation electrodes (22). Groups (60), (61) of modulation electrodes (22) are electronically addressed in steps of one modulation electrode (22) each, across the width of the print array (16). To prevent cross-talk from rendering the sensed ion current (20) values unusable, the modulation voltage (Vm(i)) is adjusted by a feedback circuit (42) to achieve a fixed value of ion current (20) for each group (60), (61). Values of this modulation voltage (Vm(i)) are stored in an electronic data file (44). Computation of corrected modulation voltage (Vm(i)') to produce uniform ion current (20), based on average modulation voltage and a print head (10) characteristic constant, is made in a data processor (46) by a programmed algorithm which accesses the data file (44). Corrected values of modulation voltage (Vm(i)') are applied to each correlated modulation electrode (22) through a switching circuit (52). Corrected values of modulation voltage (Vm(i)'), when applied to the correlated modulation electrodes (22), produce ion currents (20) of uniform density and result in uniformity of density in large, grey printed areas.

Abstract: A light-wave distance measuring apparatus has an intermittent control (10) continuously changing periods of time during which a light intensity modulator 1 transmits and interrupts transmitting a light intensity modulated signal so as to avoid a synchronization of the light intensity modulated signal of the present apparatus and a light intensity modulated signal from a second light-wave distance measuring apparatus. The operation of the intermittent control prevents a misfunction of the apparatus. Provisions of a self-speed detector, a time marker and a light transmission interval measurer enable the apparatus to detect the speed of a target object. Thus, the apparatus is suitable as a vehicle mount type. The apparatus accurately operates even when both the apparatus and the target object are moving. The apparatus also accurately operates without an interference even when corresponding light-wave distance measuring apparatus for vehicle are used in a small area.

Abstract: A multi-sender/switching apparatus provides a means applicable to performing either broadsender and multi-sender transfers over switching networks besides the standard network interconnections, such as point-to-point, broadcast, and multi-cast transfers. The new broadsender and multi-sender operations allow communicating over multi-stage networks, and are defined as the ability of all or multiple elements attached to the network to participate simultaneously in the same network operation on a joint basis. The system provides a capability unavailable over synchronous buffered and other types of networks. The combination of the broad-send and broadcast functions enable every element attached to an unbuffered multi-stage network to not only participate in a common network function, but to monitor the result at the same time. Likewise, through combining multi-send and multi-cast functions, multiple elements attached to the said multi-stage network can participate in a common network function and monitor the result at the same time. A multi-stage network can now perform a distributed arbitration function heretofore known only to multi-drop bus communication systems. The multi-sender/switch also incorporates a new asynchronous hand-shaking protocol that enables a positive feedback indication to be returned to the multiple senders of multi-cast or broadcast operations to inform them that the multi-sender operation is progressing correctly to all elements involved in the operation.

Abstract: A magneto-optical disc control system and method, capable of applying conventional programs directly without requiring an initialization of the whole surface of a recording medium. When a readout request of data out of the magneto-optical disc device is given from a task program via an OS, a magneto-optical disc driver outputs a readout command to the magneto-optical disc device. When returning a blank check status from the magneto-optical disc device, the magneto-optical disc driver gives a notice for representing that a normal readout is performed to the OS, sets a specific initial value for the system into a buffer designated by the task program, and writes the initial value into a readout block on the recording medium. The OS gives a notice representing that the normal readout is performed to the task program, and the task program processes the data stored in the designated buffer as the readout data of the recording medium of the magneto-optical disc device.

Abstract: A carton for holding several cigarette packs is made so that it generally resembles and functions like a conventional hinge lid cigarette pack. The carton is made from an integral blank 100 including innerframe panels E, F, G and outer member panels A, B, C, D, all arranged in a single side by side series. When the blank is folded to make the carton, the innerframe panels are positioned inside the appropriate outer member panels. The blank also includes top B2 and bottom B3 cover panels which can be closed in order to close the carton after the innerframe panels have been folded inside the outer member panels. A particularly preferred method of making up the carton is described. The consumer opens the carton by pivoting an upper portion of the outer member up and to the rear just as with a conventional hinge lid cigarette box. The innerframe interferes somewhat with this lid motion, thereby helping to keep the lid closed as in a conventional hinge lid cigarette box.
