Title: Snubber circuit system of self-extinguishing type thyristor
Inventor: KAWAMURA YUTAKA
IPC: H02M1/06
Filed: 1983-05-31
Abstract: PURPOSE:To reduce power loss by shifting charge stored in a snubber capacitor to another capacitor, and supplying to a load. CONSTITUTION:When a switch 4 is closed, the voltage of a main power source 2 is applied through a reactor 15 to between the anode and the cathode of an SI thyristor 1, and a capacitor 9 is charged through a diode 10. When a forward current is supplied to the gate of the thyristor 1, the thyristor 1 is turned ON. At this time, the charge of the capacitor 9 is shifted to a capacitor 13. Further, the charge stored in the capacitor 13 by the next OFF operation of the thyristor 1 is discharged through a reactor 12, a diode 14 and a reactor 15.

Filed: 1984-05-10
Abstract: PURPOSE:To obtain excellent zoom function without using a compensating circuit to the high voltage fluctuation by switching the frequency ratio of a write clock and a read clock of a video signal to a storage circuit. CONSTITUTION:A video signal converted into a digital signal by an AD converter 11 is written in a memory 12 in the timing of the write clock fw and read from the memory 12 in the timing of a read clock fr. When an output of an n- value command circuit 51 is at an ''L'' level, the multiple (n) of a multiplier 16 is set to n=2, then the system is activated corresponding to the circuit operation of 1 field 525-line. When the output of the n-value command circuit 51 is at ''H'' level, since the (n) of the circuit 16 is set to n=1, the relation of f2=fr is obtained. A command is issued to a reset pulse generating circuit 18 at the same time and the reset pulse has a desired timing. A resistor 22 of a vertical oscillation circuit 2 is short-circuited by a transistor 23 at the same time and the vertical sweep width is changed. Then a part of the screen is magnified.

IPC: H01L21/027
Filed: 1997-03-28
Abstract: PROBLEM TO BE SOLVED: To prevent incidence X rays from being transmitted to the rear part of an exposure device or to the outside of the exposure device even if a substrate is not located at an exposure position, by arranging a protection plate that absorbs X rays for exposure and at the same time is made of a metal material with a large mass at a path where the X-rays for exposure pass. SOLUTION: A protection plate 7 made of a metal material that absorbs X rays for exposure and is made of a metal material with a large mass is arranged at a path where the X rays for exposure pass, thus constituting a device for exposing X rays. The protection plate 7 is in flat-plate shape and has a breathing part in oblique direction and has an X-ray absorption material. When a substrate 5 is not located at an exposure position, it is installed in parallel with X rays along with a substrate stage 4, so that X rays for exposure being guided by a beam line 1 reach the rear part of an X-ray aligner 8. However, the protection plate 7 provided at the rear part of the X-ray aligner 8 absorbs or breaks the incident X rays. Also, when the substrate is located at an exposure position, X rays are broken for the rear part by the substrate stage 4.

IPC: G06F12/04
Filed: 1984-05-11
Abstract: PURPOSE:To improve the operand supplying efficiency in a pipeline system, by providing a means which continuously supplied desired operands in response to an instruction whose operation is executed. CONSTITUTION:In the case of a variable-length operand instruction using two operands, supply of the two operands is executed by repeating a specific pattern. When a condition by which one side operand supply is terminated is detected by a counter circuit 270, the termination detecting information on a signal line 501 is made ivalid by the operand supply terminating information on another signal line 312. Then continuous supply of operands becomes possible when the control information is changed to a pattern which supplies one operand only by operating a branching circuit 290 by means of the termination detecting information. Moreover, a means which checkes the positional relation of operands and performs tests is provided at the inside of an address implementing circuit 202 and a destructive overlap of operands is detected.

Title: Cryogenic refrigerating plant
Inventor: TOYODA KATSUYOSHI
IPC: F25D3/10
Filed: 1980-07-11
Abstract: PURPOSE:To recover a costly gas effectively with the discharge of gas only when necessary by arranging a pressure preserving valve on the gas pocket side of a communicating tube between the gas pocket for temporary storage and a cryogenic vessel while a low temperature vessel is inserted into the opposite side thereof in parallel with the tube. CONSTITUTION:In normal operation, a tube 13 is closed with a valve 11 while a  valve 14 is opened. With an exhausting 15 through a check valve 12, gas in a  cryogenic tank 1 is preserved temporarily into a pocket 7 via a piping 5, a heater 6  and a valve 17 and then, stored in a tank 9 with a compressor 8. A piezoelectric  converter 18 detects an abnormal pressure rise in the vessel 1 and changes over valves 11, 14 and 17 properly to store gas in the vessel 10 and the piping 13. When  a set value of a valve 12 is exceeded, the gas is heated 6 and stored 9 gradually  through a pressure preserving valve 16. After a sufficient time is allowed for the  storage, the valve 17 is switched to recover the residual gas into the pocket 7 while  with the switching of the valve 11, the valve 14 is opened so that the gas is exhausted 15 to the upstream of the compressor 8. This enables the effective recovery  of gas without releasing it into the air.
