Title: Platinum catalyst and its manufacture method
Inventor: TSURUMI KAZUNORI
IPC: H01M4/88
Filed: 1988-02-18
Abstract: PURPOSE:To provide a catalyst which maintains a good catalytic function for a long time, by depositing the catalyst metals containing platinum formed into a carbide on a carbon carrier. CONSTITUTION:The carbon consisting chiefly of carbon black and graphite is used as a carrier for a platinum catalyst intended especially for use as the electrode catalyst of a fuel cell. First this platinum and then metals such as nickel, cobalt, chrome, iron, etc., are deposited on said carbon carrier. The carbon carrier thus alloyed is further treated using steam and carbon monoxide at a temperature of about 650-815 deg.C, whereby the catalyst metals are formed into a carbide by the resulting carbons leading to the increased affinity of each of the catalyst metals for the carbon and hence the increased solidity thereof and, even if exposed to a high temperature for a long time, the catalyst metals moves on the carbon carrier to thereby prevent the surface area thereof from being reduced.

Inventor: MIKI SADAO
IPC: F16H55/30
Filed: 1992-02-24
Abstract: PURPOSE:To prevent hammering noise between a chain and a sprocket by forming circular arc parts, curved in circular arc shape around the center of adjacent tooth bottom parts as the center, at tooth faces positioned on the wound-in side of the chain, and setting the radius-of-curvature of this curcular arc part into the value obtained by deducting the radius-of-gyration of a roller from the pitch of the chain. CONSTITUTION:A circular arc part 4 of the same circular arc as the locus of a roller 11 is formed at the tooth 2 of a sprocket 1, and the roller 11 rolls in contact on this circular arc part 4 in the process of the roller 11 of a chain 10 being accommodated into a tooth bottom part 3. That is, the circular arc part 4 is formed along the circular arc shape of radius R4 around the center O of the tooth bottom part 3 as the center. This radius of curvature R4 is to be of the value obtained by deducting the radius-of- gyration R3 of the roller 11 from the pitch P10 of the chain 10. The circular arc part 4 is formed within a range of an angle theta around the center O of the adjacent tooth bottom part 3 with the tooth 2 in between. Since the radius-of-oscillation of a roller 11b and the radius-of-curvature of the circular arc part 4 coincide with each other, the roller 11b is accommodated into the tooth bottom part 3 while rolling in contact with the circular arc part 4 so as to ease a shock.

Abstract: PURPOSE:To improve the load state of a central controller at the time of congestion and to prevent the deterioration of call service by permitting a communication controller to supervise a congested state by means of a data transmission/reception frequency between the central controller and terminal controllers, and to inform the central controller of a congestion degree and permitting the central controller to give the instruction of the restriction of a data reception frequency from the terminal controllers to the communication controller from the congestion degree. CONSTITUTION:The communication controller 120 supervises the congested state of data transmission/reception between the central controller 110 and the terminal controllers 130, 131 and 13n and informs the central controller 110 of the congested state. The central controller 110 checks various data on various terminal equipments which the terminal controllers 130, 131 and 13n control and decides the terminal equipment becoming the object of communication restriction. The communication controller 120 receives communication restriction and denies data reception from the terminal controllers. When the congested state is relieved, it is informed to the central controller 110, and the central controller 110 informs the communication controller of the release of communication restriction and a system is restored.

Title: Paper feeder
Inventor: TAKAHASHI YASUHIRO
IPC: B65H1/26
Filed: 1982-03-08
Abstract: PURPOSE:To prevent a cassette from being pulled out by excessive force from a paper feeder in which the swingable bottom plate of the cassette is pushed upwards by a pressure means when the cassette is set in the paper feeder, by using a stopper to engage and halt the cassette when it is set. CONSTITUTION:When a cassette 3 is set in a paper feed position, a pressure plate 6 is turned upwards by a spring 8 to push a swingable bottom plate 4 to bring paper P into pressure contact with a paper feed roller 2. Consequently, a cassette stopper 12 is urged upwards by a spring 13 so that the top of each stopping part 12a of the stopper is protruded upwards from the hole 1c of a cassette rest plate 1 and placed in the small hole 3f of the cassette 3. As a result, the cassette 3 cannot be pulled out. When a rotary shaft 9a is then turned clockwise by rotating an operating lever 11, the pressure plate 6 is moved down to push the stopper 12 down against the spring 13 so that the cassette 3 can be pulled out from the rest plate 1.

Title: Input signal malfunction preventing circuit
Inventor: KATOU NAOYUKI
IPC: H04Q3/42
Filed: 1984-02-28
Abstract: PURPOSE:To prevent an error from being caused by correcting the presence of an erroneous pulse even if signals of the same sign are transmitted continuously and the sign is inverted on the way. CONSTITUTION:When signals at an input terminal are consecutive 1s, an AND gate A3 outputs [1], and a terminal OUT outputs consecutive 1s until the last [1] of the input signal is lost from a shift circuit S3. Thus, when the input signal is normal, the output signal has a delay of a time T (three times of pulse interval). When the 2nd pulse of the input signal changes to [0], even if the [1] based on the initial pulse P0 is shifted to the circuit S3, no [1] is outputted from the gate A1. Then [1] is outputted from a gate OR2 after the 3rd pulse P1 is shifted to the circuit S3. When a pulse Pn is lost from the circuit S3 even if the pulse before the last pulse Pn changes to [0], the output signal goes to [0]. Then even if a three-consecutive error signal exists. [1s] are outputted consecutively.
