Title: Disc brake containing hydraulic pressure generator
Inventor: IIDA KENNOSUKE
IPC: F16D65/18
Filed: 1978-05-10
Abstract: PURPOSE:To eliminate a conduit for transmitting hydraulic pressure and to prevent a disc brake containing hydraulic pressure generator from becoming non effective braking state due to damage of the conduit by containing a hydraulic pressure generator within a supporting shaft. CONSTITUTION:When a piston 14 moves within a cylinder 13 against the elastic strength of a spring 15 by pulling a brake cable rightwardly, it reduces the volume within a hydraulic chamber 17 to close an oil passage hole 25 at the initial time of this movement by a cup seal 21 resulting in high hydraulic pressure within the chamber 17. This hydraulic pressure is transmitted through a conduit 18 to an oil chamber 12 to cause a hydraulic piston 10 to move forweardly to thereby urge the frictional pad 8 onto a disc rotor 1. With this reaction a caliper 4 is rocked around a supporting shaft 3 to thereby cause the other frictional pad 9 to be urged onto the rotor 1 by the other opposite portion 6 of the capiper 4. Thus, the disc rotor is urged therebetween to occur a brake force.

Filed: 1989-03-08
Abstract: PURPOSE:To easily generate a short nano-second pulse by providing a gas tube arrester provided perpendicularly to a charging coaxial cable of a line type pulser in the direction of coaxial transmission. CONSTITUTION:The gas tube arrester 6 has a cross sectional structure as shown in figure, two electrodes 7 are provided opposite to each other via a gap 8 and some kinds of inactive gases are mixed and sealed in the inside. When a voltage over the spark voltage is applied between electrodes in air in general, there is a time delay till a spark is generated after the voltage is applied and the time is decreased as the voltage gets higher to be in a range of several tens of ns - several micro seconds. Thus, a voltage generated in a line type pulser is applied to the gas tube arrester 6 in a circuit incorporating the gas tube arrester 8 as its component and the voltage is cut off the moment a short- circuit occurs in the gas tube. As a result, a voltage with a pulse width narrower than the width of the source pulse is generated.

Title: Picture signal processor
Inventor: MURAYASU YOSHIROU
IPC: H04N5/76
Filed: 1986-03-15
Abstract: PURPOSE:To prevent a CPU side from standing by permanently and to prevent a burden in processing from increasing in the CPU side by informing a data invalid state to an external request when an effective digital video signal is not stored in a memory device. CONSTITUTION:When a vertical synchronizing signal V-SYNC is not present irrespective of the output of a request signa V-REQ, an enable signal S-EN responds to the request signa V-REQ to go to a low level and the CPU4 is brought into a stand-by state. However, since there is no vertical synchronizing signal V-SYNC, a writing signal S-VDO does not go to the low level and a RAS signal and writing completion signal V-END are not outputted. After a constant time gamma a passes, a multi-vibrator 25 resets the enable signal S-EN of the Q output terminal to a high level. Thereby, the stand-by state of the CPU4 is canceled and it does not stand by permanently. Since an effective signal S-VAl goes to the low level, it is detected that the effective video signal is not present in the memory and a wasteful output to a printer is not performed.
