Title: Working method of shaft blank material
Inventor: NAKAMURA TERUSHIGE
IPC: B21K1/14
Filed: 1979-09-29
Abstract: PURPOSE: To achieve the additional saving of cutting work and the improvement of yield by plastically working the surface of a shaft blank material which is engaged and supported into the center holes on both end faces by a pair of centers, by moving a die between the centers, which is coaxial to the axial center of the centers, parallel to the axial center.  
     CONSTITUTION: A shaft blank material, for example, a drive shaft blank material 305, is obtainable by cold plastic working, and coaxial center holes are formed on both end faces thereof. Stationary and movable centers 403, 405 which coaxially oppose to each other on a base 401 are engaged with these to support the blank material 305. Next, a die supporting base 407 fitted with a die coaxially to the axial center of both centers between both centers is moved rightward of the figure by a hydraulic cylinder for press whereby teeth are formed on the teeth part 304 of the blank material. At this time, the left side end part 302 of the blank material receives tensile force, but since constant pressing force in the rightward direction of the figure is held exerted to the center 405 by a hydraulic cylinder 406, no elongation occurs. The spline part 306 of the blank material is worked in the similar manner and these may be worked with good concentricity.

Abstract: PURPOSE:To prevent standing of gas on an electrode surface, to cool the electrode and thereabout by adiabatic expansion, and to stabilize charge of a laser device to increase efficiency by providing a porous electrode to a gas laser device and by supplying laser gas through the inside thereof. CONSTITUTION:The outside of porous electrodes 12A, 12B which are produced by porous materials of a gas laser device is covered with an electrode cover 13. A laser gas supply tube 14 is opened inside the electrodes 12A, 12B and fresh laser gas is supplied to the supply tube 14 along an arrow 15. The laser gas flows through the electrodes 12A, 12B to blow out from the inside to an charge tube 1, and agitates the surface of the electrode 12A, 12B and thereabout to prevent the gas from standing there and also to cool the surface of the electrodes 12A, 12B and thereabout through adiabatic expansion of gas blowing. Unstable charge is prevented by the process of agitation and cooling, thus circulating the supplied laser gas along an arrow 8 in a gas circulation tube 2. Charge can be stabilized in this way.

Title: Semiconductor device and production thereof
Inventor: UNNO HIDEYUKI
IPC: H01L21/76
Filed: 1984-06-20
Abstract: PURPOSE:To remarkably improve the crystallinity of a silicon this film and to thereby improve the characteristics of a device as an MOS transistor or the like formed on a silicon thin film, by inclining each side of a rectangular mask pattern for defining the planar shape of the silicon thin film by a certain angle with respect to the cleavage direction. CONSTITUTION:Each side of a silicon this film 12 is formed so as to be inclined by the angle theta with respect to the 100 direction. When porous silicon is oxidized, a stree A is generated in the silicon thin film 22, according to the variation of coefficient of thermal expansion and the volumetric change during the oxidization of the silicon and of the porous silicon oxide film. If any crystal defect is produced in the silicon this film 22, a stress B (a component of the stress A in the cleavage direction) which causes the defect is reduced to Acostheta because the stress A is changed by the angle theta with respect to the cleavage direction in which a crystal defect tends to be produced. The angle theta may be from about + or -10 deg. to the maximum value of + or -45 deg. where the pracatical effect of reducing the stress becomes noticeable. Accordingly, the occurrence of defects can be controlled.

Abstract: PURPOSE:To maintain stable re-start of burning and suppress production of unburnt HC and smoke to a minimum by increasing the amount of fuel supplied to a combustion chamber after an approximately minimum amount of fuel which can form combustible air-fuel mixture around an ignition plug has been supplied into the combustible chamber. CONSTITUTION:A fuel injection from a fuel injection nozzle 14 to a combustion chamber 4 is stopped when an engine is decelerated suddenly. When the engine speed is lowered to a self-recovering speed at the time t0, the fuel injection is re-started.

Abstract: PURPOSE:To secure the dielectric strength and level margin of an amplifier by performing the switching control of a differential amplifier based on the output signal of a differential amplifier circuit in which the change of input data is moderated by using a time constant circuit, and forming the application voltage of a magnetic head. CONSTITUTION:A first differential circuit receiving the input data Din forms output voltages Vd and Vc whose change are moderated by the time constant circuit consisting of load resistors R1, R2 and capacitors C1, C2, and supplies them to the bases of differential transistors (TR) Q3, Q4. The level change of current switching control voltages V'd, V'c transmitted to the bases can be moderated. Thereby, since the current iH on the magnetic head HD can be switched moderately, the pulse shape flyback voltage of the head HD can be also reduced to a negligible level. Contrarily, the input data Din is made into large amplitude by a second differential circuit. The voltage VB is supplied to the two terminals (a), (b) of the head HD via output TRs Q1, Q2 as clamping voltages Va, Vb. A write current switching time can be accelerated by increasing the voltage VB.
