Abstract: PROBLEM TO BE SOLVED: To maintain basic three characteristics, namely, fusion resistance, voltage resistance, and breaking at a certain level, and obtain superior arc consumption resistance characteristics and re-arc characteristics by integrating WMO in Cu alloy in which a specific average particle size of W and Mo and a specific rate is contained and specifying a specific average particle size. SOLUTION: W of 0.4 to 6 micrometers in average particle size is 74 to 88wt.%, Mo of 0.4 to 4 micrometers in average particle size is 0.001 to 5wt.%, and the remaining part is Cu. Due to this quantity containing W, a required high hardness and high fusion property are obtained without lowering conductivity, re-arc generation frequency, breaking characteristics, static pressure resistance characteristics are obtained in this average particle size of W, and the average particle size of WMo particles is less distorted. Mo of this contained quantity is integrated as an auxiliary component of W, and wetting property with W and Cu is improved, the average particle size of WMo particle is 0.4 to 10 micrometers, and thereby radiation of micro-metal particles and surface coarseness are reduced in the case of a single component. This alloy may contain Mo and Fe.  This manufacture is by invasion method or sintering method or the like.

Abstract: PURPOSE:To improve a mechanical durable life of an interrupter by specifying a relation among the gap between both contacting elements in the movable side and in the fixed side, the gap between stoppers in an operational part, and an idleness in the operation direction of a joining part. CONSTITUTION:In a vacuum interrupter 5, a fixed side terminal 9 is fixed by a fixing metal fitting 3 and a sagging conductor 5 and a joining metal fitting 16 are fastened and fixed in a movable contacting element 8. The contacting element 8 and a fixed contacting element 7 are kept from each other by a gap G1. Also, a stopper 23 and a fixing metal fitting 4 are kept from each other by a gap G2 and the stopper 23 receives power P3 downward between the fixing metal fitting 4 and it by a returning spring 20. There is a step in the stopper side 23 of the joining metal fitting 16 and there is idleness G3 between the step part and the stopper 23 in the open pole state. The gaps G1, G2, and G, have a relation among them; G2> G1> (G2-G3). Consequently, since the working impact affecting the spring 20 is not transmitted to a container of the interrupter 5, the container is prevented from being damaged and the usable life of the interrupter 5 is extended.

Title: Manufacture of softened rod or wire rod
Inventor: KANBARA SUSUMU
IPC: C21D8/06
Filed: 1989-01-11
Abstract: PURPOSE:To manufacture a softened rod or wire rod free from the occurrence of breakage and season cracking without requiring descaling stage by subjecting a steel stock containing specific amounts of C to finish rolling and cooling under respectively specified conditions and then applying spheroidizing annealing to the above in a state where scales remain adhering to the surface of a product in a specific atmosphere. CONSTITUTION:At the time of hot-rolling a steel stock containing <=1.5% C, finish rolling is carried out while controlling finish rolling finishing temp. to <=850 deg.C, and, after the conclusion of rolling, cooling is carried out down to 500 deg.C at 0.5 deg.C/sec-<4 deg.C/sec cooling rate. Subsequently, after cooling down to room temp., spheroidizing annealing is carried out in an atmosphere containing inert gas by >=90% in a state where scales remain adhering to the surface of a product. By this method, the softened rod or wire rod can be manufactured without causing decarburization even if annealing is exerted in an inexpensive inert gas, and further, hardness can be sufficiently reduced and die life at the time of cold forging can be prolonged.

Title: Constant current source circuit
Inventor: ISHIKAWA TAKASHI
IPC: G05F3/22
Filed: 1984-01-13
Abstract: PURPOSE:To obtain a constant current source circuit which can extract a constant current of a prescribed multiple as high as a reference level with high accuracy, by securing the coincidence of voltage drop between the 1st and 2nd tunnel resistances by connecting in parallel the 2nd tunnel resistance by N times as much as the 1st tunnel resistances. CONSTITUTION:Two equal tunnel resistances 15 are connected in parallel to the emitter of a transistor 12 which produces an N-fold current as high as a reference level. While a resistance 13 also uses the same resistance 15. Therefore the voltage drop is set at V/RT+2R (RT: resistance value of the resistance 15 and 2R: resistance value of a resistance 17) at both resistances 13 and 17 by a reference current I1. While the voltage drop is set at V/(RT/2+R) at resistances 14 and 18 by a current 2I2 double as high as the reference level, where RR/2 is the parallel connection resistance of the resistance 15 and R is the resistance value of the resistance 18. The ratio between these two currents is defined as I1/I2= 1/2. Thus the effect due to the voltage drop of the tunnel resistance can be reduced.

SOLUTION: In this exhaust gas recirculation(EGR) valve, a valve seat 18 and a valve element 16 are equipped in a valve housing 21, and a collar 23 of a return spring 17 is engaged with a valve stem 15 connected to this valve element 16 by means of screwing, energizing them in the valve closing direction. In addition, a driving part 20 is installed at the opposite side against the valve element 16 of the valve stem 15. This driving part 20 is made up of a diaphragm 13 forming a pressure chamber 12, a driving shaft 14 shifting in the axial direction due to a change of pressure in the pressure chamber 12, and a return spring 27 energizing this driving shaft 14 in the valve closing direction. Then air pressure is regulated by a regulator, and thereby air is fed to an air inlet 11 of the driving part 20.  Pressure in the pressure chamber 12 varies according to the magnitude of this air pressure and thereby the driving shaft 14 is slidden into motion, and thus valve opening in the valve element 16 is determined.

Abstract: PURPOSE:To fill a fine contact hole morphologically by forming the adsorption layer of titanium tetrachloride to a substrate and applying pulse-shaped light having a wavelength absorbed on a material surface on the bottom of an opening section at the initial stage of deposition. CONSTITUTION:A titanium-tetrachloride adsorption layer 6 is shaped through exposure in the atmosphere of a titanium tetrachloride gas. When the whole surface of a substrate is irradiated with light 7 having a wavelength transmitted through the titanium-tetrachloride adsorption layer 6 and a silicon-oxide insulating layer 4 in the atmosphere of tri-isobutyl aluminum and absorbed on a silicon surface, heat is generated by absorption on the surface of silicon or Al, tri- isobutyl aluminum is thermally decomposed through the titanium-tetrachloride adsorption layer 6, and the decomposition of tri-isobutyl aluminum is accelerated by a catalytic effect by titanium tetrachloride adsorbing at that time. After nucleation, the whole surface of the substrate is heated, sufficiently high vapor pressure is acquired, and the titanium-tetrachloride adsorption layer not light- heated is evacuated and removed. Accordingly, burying into a fine region such as a contact hole can easily be conducted morphologically.
