Abstract: PURPOSE:To prevent the deterioration of element properties or the integration of a device by a channel stopper by using a mask which has a second mask layer left in a circumferential step pad part of a first mask layer on an insulating film of an Si substrate. CONSTITUTION:An Si3N4 film 3 is arranged on an SiO2 film 2 of an N type Si substrate 1 to form a photoresist mask 4 and after etching a resist 4' extending over the film 2 on the circumference of the film 3 is formed by heating. Next, when N<+> ion implantation layer 6 is formed, only the extending film 4' is formed outside the film 3. The resist 4' is removed and a field oxidized film 7 and an N<+> channel stopper 8 are formed at the same time using the Si3N4 film 3 as a mask. The Si3N4 film 3 and the SiO2 film 2 are removed and an FET is formed by a well-known method. In this constitution, as the channel stopper 8 is arranged apart from an active region, a P<+> type source-drain 11 do not overlap the channel stopper 8, thereby reducing a conjunction capacity and increasing dielectric resistance substantially. In addition, increase of integration is possible by reducing an active region.

Filed: 1981-10-23
Abstract: PURPOSE:To prevent a load from the supply of uncontrolled voltage when a control pulse can not be supplied to a main switching element especially by circuit failure or the like by stopping the oscillation of a self-oscillating circuit just after the rise of an auxiliary power source. CONSTITUTION:When an input power source 1 is turned on and a self-oscillating circuit 9 starts to operate, the voltage of a capacitor 21 in an auxiliary power source 14 is raised through a main transformer 11. If the voltage of the capacitor 21 rises higher than the voltage of a Zener diode 51, current is supplied to a photocoupler 53. Light from a light emitting diode 53a is detected by a photodetecting phototransistor 53b and a trigger signal is inputted to a thyristor 55 through a resistor 54. The connection of the thyristor 55 drops the voltage applied to the self-oscillating circuit 9, so that oscillation is immediately stopped. When a control pulse can not be supplied to a main transistor 12 by circuit failure or the like, a load 13 is prevented from the supply of uncontrolled voltage.

Abstract: PURPOSE:To aim at reducing the fuel consumption of an engine during running at a low speed, by providing tow rocker arms which are made into contact with high and low speed cams, respectively, and by providing a means for changing over between the coupling and releasing of both rocker arms. CONSTITUTION:When an engine runs, for example, at a low speed, the coupling between first and second rocker arms 7, 8 is released by a coupling change-over means 21. That is, hydraulic pressure in a hydraulic pressure chamber 29 is released so that a stopper 24 is moved toward the first rocker arm 7 by means of a spring 25, and a piston 23 is retracted until it abuts against a stepped part 27. Then, the abutting surfaces of the piston23 and the stopper 24 correspond to the sliding surfaces of both rocker arms 7, 8 so that both rocker arms 7, 8 fall in such a condition that they are angularly displaced relative to each other. As a result, the first rocker arm 7 is swung in accordance with the slide operation of thereof with a speed reducing cam 3 in association with the rotation of a cam shaft 2 and therefore, both intake valves 1a, 1b are opened and closed having timings and lifts which are different from each other.
