IPC: H01H33/66
Filed: 1989-09-29
Abstract: PURPOSE:To prevent generation of high excess voltages with a small chopping current during cutoff of a small current and also prevent the large current cutoff performance of a vacuum valve from being damaged by joining ring-shaped arc contacts made from low steam-pressure metal and cup-shaped contacts made from high steam-pressure metal or low conductive metal to the respective open side end faces of cup-shaped contact stands. CONSTITUTION:Ring-shaped arc contacts 14, 14 made from low steam pressure metal are joined to the respective open side end faces of a cup-shaped fixed side contact stand 5 and a cup-shaped movable side contact stand 8. Cup-shaped contacts 15, 15 made from low-conductive metal containing a large amount of high steam pressure metal are disposed inside the arc contacts 14, 14 and are joined to the respective contact stands 5, 8 via bar-shaped conductors 16, 16 which are coaxial with the cup- shaped contacts 15, 15. Thus a small current is cut off with a small chopping current between the contacts 15, 15 made from high steam-pressure metal or low conductive metal, while a big current ls cut off with a small amount of exhaustion of contacts between the ring-shaped arc contacts 14, 14 of low steam-pressure metal. Thus cutoff of small current and large current is assigned to respective suitable contacts so that a desirable cutoff characteristic is obtained over the whole current region.

Title: Gas purification and feed system
Inventor: UMEDA KATSUMI
IPC: H01L21/02
Filed: 1991-10-02
Abstract: PURPOSE:To maintain high purity of in-system gas by a method wherein the pipings connecting a gas feed system, a gas purifier and gas using devices are arranged in loops so that the gas passing through the gas purifier is constantly circulated through the gas pipings. CONSTITUTION:Nitrogen fed from a gas feed system 1 is passed through a gas purifier 2 to remove the containing impurities and then branched by a three way valve 8 to be fed to gas using devices 5, 6. At that time, when the gas consumption is low or the pipings run dead ends, the gas purity is deteriorated by a trace of impurities deposited from the pipings between the gas purifier 2 and the gas using devices 5, 6 as well as from the piping accessories, and thereby the nitrogen must be fed back from the piping ends to the gas purifier 2 using a rated capacity boosting circulation pump 4 in order to form a constant gas flow in the pipings. Through these procedures, the purity of the applicable gas can be ensured and stabilized.

Abstract: PURPOSE:To allow switching circuit to cope with a change in a connection line ratio without interruption of the operation by connecting one input or more of an optical spatial division switch of a 1st switch to an output of an optical spatial division switch of a 2nd switch by an optical transmission line. CONSTITUTION:S switches 11, 21 are optical spatial division switches, an optoelectric converter (EO) is connected to an input side of a T switch and an electrooptic converter (OE) is connected to the output side and an optical fiber 4 is used for a direct coupled path. The switch copes with a high speed signal by revising the direct coupled path with an optical path and even when the S switches 11, 21 are installed apart, no waveform deterioration nor crosstalk is caused. Thus, the S switch is adopted as the switch 11 and the fiber 4 is adopted for the direct coupled path and the signal from the direct coupled path and the signal from the T switches 12, 13 are synthesized in the state of light. Thus, even when the ratio of the connection line is revised, the connection destination of the signal may only be changed from a control section and it is not required to disconnect the operating part and then transient interruption of the operation is not required.
