Title: Safety valve for gas cylinder
Inventor: KUROODO FURUNIYON
IPC: F17C13/04
Filed: 1990-09-25
Abstract: PURPOSE: To enable charging in addition to decompressing function by providing a piston with upstream and downstream communicating paths, maintaining first and second valves upstream and downstream of the piston, in closed positions by cylinder gas pressure, and constituting the first valve to be opened by mechanical action and gas pressure upstream of the piston. CONSTITUTION: In the case of charging, a connecting head 24 is connected to a gas source, and a valve device 18 is opened by gas pressure to spread gas in a chamber 40 through a passage 52. The valve device 18 is opened, and gas enters a gas cylinder. After charging, the connecting head 24 is detached from the gas source. Then gas pressure maintains the valve device 18 in a closed position, and the valve device 28 is closed by the pressure of the chambers 40, 48. In the case of exhausting gas, the connecting head 24 is connected to a gas using circuit to hold the valve device 28 in the open position, and the pressure of the chamber is reduced. A piston 34 therefore descends to push clown a rod 22, and the valve device 18 is opened to exhaust gas.  When the pressure of the chamber 40 becomes large, the piston 34 ascends to close the valve device 18, and thereafter this is repeated at high speed to reduce pressure.

Abstract: PURPOSE:To obtain a speed waveform which attains speedy positioning while the change quantity of acceleration is restricted by deciding acceleration and a speed, which coincide with a command speed, from acceleration calculated from a speed command difference and an acceleration allowance value etc., and correcting said acceleration and the speed in a prescribed way. CONSTITUTION:An acceleration command calculation part 1 calculates first acceleration A<1>i from the difference of the speed command V1ci at every sampling period. A speed control calculation part 2 decides second acceleration A<2>i and a second speed V<2>i from acceleration A<1>i, the command Vci, a precedent output speed Vi, output acceleration Ai and the acceleration allowance change value of a built-in memory.

Title: Control circuit for electrostatic induction thyristor
Inventor: HAYAZAKI YOSHIKI
IPC: H02M1/08
Filed: 1990-09-25
Abstract: PURPOSE:To reduce the number of used parts and the malfunction of a switching device for controlling turning-off by connecting both electrodes of a series circuit composed of a DC power source and the switching device to the gate and cathode of an electrostatic induction thyristor in the direction in which the cathode side becomes positive. CONSTITUTION:When the turning-on of an electrostatic induction thyristor 1 is controlled, a light emitting element 3 is made to emit light by turning on a switching device S2 for a period t1. As a result, an electromotive force is produced from a solar battery 2 optically coupled with the element 3 and biases between the gate and cathode of the thyristor 1 in the forward direction, resulting in the turning on of the thyristor 1. The turning-on current supplied to the thyristor 1 can be adjusted freely by appropriately selecting a resistance 4, the element 3, and the battery 4. When the turning off of the thyristor 1 is controlled, another switching device S1 is turned on for a period t2. Therefore, the number of required DC power sources can be reduced to one and, at the same time, since the solar battery has a reverse blocking characteristic, the malfunction of the switching device can be prevented.

Filed: 1997-09-22
Abstract: PROBLEM TO BE SOLVED: To provide a method of manufacturing a transistor gate, capable of suppressing damage of a gate oxide without sacrificing advantage of an ideal anisotropic plasma etching. SOLUTION: A directress layer 14 is formed on the first conductive layer 11, and part of the first conductive later 11 is exposed by forming an opening 15 in the dielectric layer 14.
