Title: Multi-way multiplex communication system
Inventor: IWASAKI TOMOMI
IPC: H04W76/02
Filed: 1999-04-23
Abstract: PROBLEM TO BE SOLVED: To provide a multi-way multiplex communication system capable of increasing subscriber capacity even in a system that the number of telephone subscribers per subscriber station is small and there are not much calls in the same subscriber station. SOLUTION: When subscribers 15 and 16 in a first area 10 are to speak, a base station 1 judges intra-area speaking and applies the instruction of an intra-call 31 to a repeater station R1 located at the center of the first area 10. When the instruction of the intra-call is received from the base station 1, the repeater station R1 returns a main incoming signal to a main outgoing signal and multiplexes them and since a time slot is released concerning a high-order station and the other areas, the same time slot as a time slot, which is used for the intra-call in another communication area, can be used.

Title: Gravure plate making method
Inventor: SHIGETA TATSUO
IPC: B41N1/06
Filed: 1985-05-29
Abstract: PURPOSE:To provide a gravure plate making method capable of shortening the time before a printing roll is mounted to a printing press, by performing chromium plating for imparting printing durability after substrate copper plating or Ballard copper plating and subsequently performing the coating of a photosensitive film, baking, etching and resist release in this order to complete plate making. CONSTITUTION:After copper substrate plating was applied to a substrate roll made of iron, grinding is applied to the plated roll by a rubstone grinder and a selenous acid or silver coat layer is subsequently formed to the roll and Ballard plating is further applied thereto and mirror surface finishing is applied to the plated roll by a buff grinder. A chromium plating for imparting printing durability is applied to thus formed mirror surface roll and baking, etching and resist release are performed to complete plate making. In the case of direct adhesion, the substrate roll made of iron, to which copper plating was applied, is polished by grinding and further subjected to buff polishing while chromium plating for imparting printing durability is applied to the treated roll and baking, etching and resist release are performed to complete plate making. In reutilization after the finish of printing, the chromium plating is released by etching and the exposed surface of the roll is ground by a rough grinder and again subjected to copper plating.

Filed: 1996-05-10
Abstract: PROBLEM TO BE SOLVED: To certainly print characters including qualifications in a perfect form by a method wherein when the qualifications of characters are set by a character qualification setting device, the character size including character qualification is corrected to a size smaller than the printable size of a printer. SOLUTION: A qualification of a character is selected and set by a character qualification switch 62 and stored in a RAM 54 when a character qualification is performed. A CPU 50 calculates print size including the character qualification, and compares the character size calculated with the printable maximum size of an ink jet head. When the print size calculated is larger than the printable maximum size of the ink jet head, the character size that is selected and set is reduced one rank and input to the RAM 54 so that the print size is finally corrected to the printable size of the ink jet head.

Filed: 1986-05-21
Abstract: PURPOSE:To remove the slack in a recording paper, by providing a link member for moderating a pressing force of a second feeding roller when a first roller is out of contact with the recording paper, in conjunction with a roller- supporting means. CONSTITUTION:When a recording paper 7 is fitted in position and a driving roller 25 and a payout roller 26 are rotated, a roll 8 of the recording paper is rotated in the direction of an arrow C, and when the recording paper 7 reaches a feeding roller 21, all rollers stop rotating. A cam 19 is rotated, and a push rod 16 is moved in the direction of an arrow H to push a pin 20. A pinch roller 10 having been strongly pressed against a capstan roller 9 by springs 13 and 15 is now pressed by only the spring 13 with a weaker force. A cam 32 is also rotated, a roller support plate driving member 29 is turned in the direction of an arrow G, and the roll 8 is brought into contact with a bottom part of a recording paper support base 24. Since the movement of the paper 7 is accompanied by a high resistance and the pinch roller 10 is relatively weakly pressed against the capstan roller 9, the paper 7 is moved while being pulled by the capstan roller 9 and the pinch roller 10, whereby the slack in the paper 7 is removed.

Title: Torque transmission
Inventor: ENOMOTO KOUJI
IPC: F16H59/38
Filed: 1982-07-07
Abstract: PURPOSE:To enable to maintain the relatively rotating speed between the input shaft and the output shaft of a torque transmission as desired by calculating the actual relatively rotating speed between a frictional clutch piston and a shell cover from the variation in the hydraulic pressure which is detected by a hydraulic sensor. CONSTITUTION:Whenever a frictional clutch piston 10 and a cover shell 12 relatively rotates so that grooves 44a, 44b and a groove 12a are superposed, an applying chamber and a releasing chamber communicate with one another, and the hydraulic oil of the releasing chamber varies in response to the relative rotation (i.e., the hydraulic pressure rises in a pulsing state), and this variation in the hydraulic pressure is converted to a hydraulic sensor into an electric signal. Accordingly, a pulse which responds to the relative rotation to the electric signal is generated. This electric signal is fed to a computer, which counts the number of pulses, thereby calculating the relative rotating speed.

Filed: 1983-06-29
Abstract: PURPOSE:To destroy an insulating film of a coupling agent easily and securely without damaging a transparent electrode formed on a glass substrate by applying a DC voltage between both surfaces of the coupling agent. CONSTITUTION:When an insulator 4 is provided onto a transparent substrate 2 formed on the glass substrate 1 through the coupling agent 3, the DC voltage is applied between both surfaces of the coupling agent 3 to destroy the insulating film of the coupling agent 3. Consequently, there is no possibility of damage unlike mechanical polishing and no irregularity of adhesive strength of insulation unlike removal by dilution. The coupling agent in this case is tens - hundreds of Angstrom  thickness and has unstable electric characteristics, so it is destroyed easily by applying the DC voltage of tens of V. Thus, a high-reliability liquid crystal panel is obtained.
