Abstract: PURPOSE:To avoid pattern shift and form ultra-fine pattern with high accuracy on the occasion of manufacturing IC by inclining the axis [100] for the specified angle [011] from the direction perpendicular to the silicon substrate surface. CONSTITUTION:The axis [100] of substrate is inclined by 1 deg.-10 deg. in the direction of axis [011] from the direction perpendicular to substrate surface 2 in a semiconductor device where an epitaxial growth layer 4 is formed on the surface (100) of a silicon substrate 1. When the axis [100] is inclined in the direction of axis [011], the pattern shift amount is small irrespective of the condition of gas, etc. during the epitaxial growth and pattern shift seems to be not generated almost until the thickness of epitaxial growth of about 20mum. On the other hand, when the axis [100] is inclined in the direction [001], pattern shift amount is large and difference depending on the kinds of gas is also large.

Abstract: PURPOSE:To obtain picture images of constant density by providing a means for detecting the using extent of a photoreceptor, and calibrating the control level of exposure to the level corresponding to the characteristics of the photoreceptor when the preset using extent is attained. CONSTITUTION:The rise and fall characteristics of a photosensitive drum 1 are compensated by controlling the exposure upon the photoreceptor, and a counter which counts the number of revolutions of the photoreceptor is used as a means for detecting the using extent of the photoreceptor, so that the control level of exposure is calibrated and controlled in accordance with the change in the photosensitive characteristics corresponding to the count number. More specifically, as the control circuit is shown in the figure, a counter 10 is so arranged as to count the number of revolutions of the photoreceptor 1, that is, the times  of formation of latent images. The counter 10 is reset at every exchange of the photoreceptor 1. The quantity of light is controlled by changing the lighting  voltage for a halogen lamp 11 which is a light source for irradiation of light  images according to the output of the counter 10.

IPC: B23H1/02
Filed: 1985-01-30
Abstract: PURPOSE:To increase a machining speed, by connecting the second switching transistor, which decreases a time width of pulse voltage, across poles so as to lessen finished surface roughness. CONSTITUTION:An electric discharge circuit connects between pulse osciallators 15 and 17 a delay circuit 19 which delays the rise-up of a pulse of the pulse oscillator 17 by a time T. If a pulse of the pulse oscillator 15 is applied to the base of a transistor 11, voltage across poles rises. While after the time T, if a pulse of the pulse oscillator 17 is fed to the base of a transister 13 parallelly connected across the poles, the transistor 13 is electrified short- circuiting the poles. Accordingly, the electric discharge circuit, dropping the voltage across the poles, equalizes its waveform almost to the waveform of the pulse osciallator 15.

IPC: H03K17/78
Filed: 1986-01-25
Abstract: PURPOSE:To realize a semiconductor relay circuit which can execute switching at a high speed, by a simple circuit constitution using an insulation gate planar thyristor, by providing a control circuit for executing quickly charge and discharge of a control voltage of a switching element. CONSTITUTION:A MOSFET 9a of an enhancement type is used as a switching element. When a resistance value of a resistance 8 is set in advance so that a voltage V1 across the resistance 8 exceeds a threshold voltage VTH1 of an N channel MOSFET in an insulation gate planar thyristor IGT 6, when the voltage V1 has exceeded the voltage VTH1, an FET in the IGT 6 becomes a conducting state, and a positive charge which has been accumulated in a gate of the FET 9a flows from an anode terminal of the IGT 6 to a cathode terminal. The flow of this charge becomes a trigger current and causes a thyristor phenomenon of the IGT 6, and discharge quickly the positive charge which has been accumulated between a gate and a source of the FET 9a.

Abstract: PURPOSE:To obtain a desired processing region by arranging clampers on a fixed side and on a moving side having extremely little contact surface formed in the right angles with the irradiation outlet of laser beam and laser beam axis so that the contact surfaces may face each other. CONSTITUTION:A clamper 80b on a moving side is driven by an air cylinder 10 as a pressure holding means with a fixed end 13 as a reference. In the clamp of a work 1, the clamper 80b is moved so that surfaces 81 of each clamper 80a and 80b coming into contact with the work 1 will get into surface contact without fail. The accuracy is improved by the use of linear driving guides 11a and 11b and the surface contact is kept well. After the work 1 is thus clamped, laser beam 7a is led to a processing section with a system (a) and is directed to the work 1 from an irradiation outlet 9a of a fixed side clamper 80a. At this moment, the work 1 is always kept at a constant height with a work guide 12 so as not to shift the position to be irradiated by the laser beam 7a.

Title: Remote control circuit

Filed: 1983-01-31
Abstract: PURPOSE:To prevent such danger that equipment continues to operate owing to a connection defect of a signal transmission line, etc., by allowing a remote control part to operate a receiving circuit on the basis of the OR output between the output signal of the receiving circuit and the signal of a time limiting circuit. CONSTITUTION:The output of the time limiting circuit 12 is at a level L in a normal state for a specific time after the power source is turned on, the receiving circuit 8 continues to operate by its output, and the output of a DC converting circuit is at a level H. If a conduction defect occurs to the signal transmission line, a latch output of a port -O of the receiving circuit 8 is outputted and the output of the DC converting circuit 13 goes down to the level L to hold a gate 14 at the level L, so that high impedance is obtained at the output ports of the receiving circuit 8 at a time. At the same time, the signal of an operating circuit 11 is not transmitted to a main control means 4 at a main frame side A because a scanning signal is not inputted to a transmitting circuit 10. Consequently, this system regards that as a safety-side operation stop signal and stops.

Title: Controlling device for quantity of intake-air of diesel engine
Inventor: OKAMOTO KAZUO
IPC: F02D9/02
Filed: 1979-02-14
Abstract: PURPOSE: To lower the noises produced by combustion (or explosion) of fuel, by eliminating turbulences of air drawn into cylinders in low-speed operational range of engine.  
     CONSTITUTION: Distributor type fuel injection pump 2 is arranged such that pressure at the outlet of a feed pump or pressure in a fuel reserving tank in the feed pump is raised in proportion to the revolutional speed of engine 1. Therefore, when engine 1 is operated at its idling speed, pressure at the outlet of the feed pump in fuel injection pump 2 is low and it is transmitted via conduit 6 to chamber 7 in actuator 20. Here, piston 8 is retained in its retracted position by the force of spring 9, so that air passage through intake pipe 14 is restricted by throttel valve 15. Accordingly, flow speed of air introduced through air cleaner 13 is decreased rapidly after the intake air passes through throttle valve 15. Then, the intake air is carried through intake manifold 21 and drawn into cylinders with its turbulences being removed completely.
