Title: Clutch-brake device
Inventor: KITANO SEIICHI
IPC: F16D67/02
Filed: 1986-05-12
Abstract: PURPOSE:To smoothly select a clutch and a brake, by independently arranging a brake portion and a clutch portion, and controlling a timing of ON-operation of the brake and the clutch. CONSTITUTION:A clutch portion 52 and a brake portion 66 are independently arranged. When a lever operation is released to select a clutch engaging condition from a brake operating condition, the pressure contact between a brake surface 62 and a brake surface 62 is first released to effect the OFF-operation of the brake portion 66. Then, a pressure ring 88 is moved away from a pressure plate 58. Therefore, after the OFF-operation of the brake portion 66 is completed, the ON-operation of the clutch portion 52 is started. Accordingly, since the clutch portion 52 and the brake portion 66 are independently arranged and controlled, the selecting operation between the clutch and the brake may be smoothly effected.

Title: File writing processing system
Inventor: YOSHIDA HIROSHI
IPC: G06F3/06
Filed: 1988-04-30
Abstract: PURPOSE:To increase the processing speed of a device which stores the data received from plural input devices into a file by defining previously the storing position of each data received from each input device and storing data through each input device in parallel with each other. CONSTITUTION:The data received from plural input devices are stored once in a buffer 3 and an input/output processing part 22 gives a request to a file control part 26 together with the stored input/output data length for the information on a file writing area. Then the part 26 takes successively the requests out of a queue 27 and informs the writing position information 28 to the part 22. The part 22 writes the information stored in the buffer 3 to a file 9 and processes this information. In this case, these writing jobs can be carried out in parallel with each other since the areas of the files 9 are different from each other by the parts 22.

Title: Output buffer circuit
Inventor: SUZUKI YASOJI
IPC: H03F3/34
Filed: 1978-09-05
Abstract: PURPOSE:To achieve output current increment and temperature compensation of a MOS transistor circuit by an output buffer circuit having the mirror constitution dependent upon emitter follower. CONSTITUTION:Output buffer circuit 22 used for increasing the output current of an operational amplifier consists of output buffer 21 and temperature compensation circuit 22, and the output of the operational amplifier has the output current increased considerably due to emitter follower constitution of output buffer 21. Then, since a MOS transistor used as a load has a negative temperature characteristic and bipolar transistor Q21 used as the emitter follower has a positive temperature characteristic, temperature compensation circuit 22 is constituted by the same constitution as the output buffer, thereby forming a mirror circuit. Then, the output of compensation circuit 22 is used as the gate bias of MOS transistor Tr21. Consequently, circuits 21 and 22 are changed similarly for output (Out) to hold the output DC voltage constant due to the gate bias.

IPC: G03B15/05
Filed: 1980-08-08
Abstract: PURPOSE:To lower trigger voltage and eliminate the need for any trigger transformer and the like by using an element provided with 3 poles in a gas tube for control. CONSTITUTION:When the electric charge of a capacitor 2 is discharged through a trigger coil 4 by turning on a switch 1 for light emission, high voltage is generated in the secondary side 3' of the coil 4 and a main electric discharge tube 4 is excited. Then, a main electric discharge capacitor 5 starts electric discharge through the tube 4. A photodetector 8 is conducted by reflected light to supply charge to an integration circuit. When required quantity of light is attained, an SCR goes on to generate voltage across a resistance R1. The voltage across the R1 is applied to the electrodes of a tube for control, thereby performing temporary discharge. The charge of the main discharge capacitor is discharged by this discharge. Thereby, the light emission of the tube 4 is stopped. With such constitution, the trigger voltage is lowered and the need for trigger transformers and the like is eliminated.
