Filed: 1979-12-26
Abstract: PURPOSE:To make it possible to achieve element segregation by a V-shape groove without bird beak phenomenon, by nitriding surface of amorphous silicon deposited in the V-shape on a silicon substrate. CONSTITUTION:A V-shape groove which is to become a segregating region is formed on a silicon substrate 1, and an insulation membrane consisting of SiO2 membrane 2 is attached onto the surface along this V-shape groove. Further, an amorphous silicon 3 is deposited in the V-shape groove, and then, by treating it in bitrogen-containing atmosphere or injecting nitrogen ion into it, a nitride membrane 10 is formed on the surface of the amorphous silicon 3. As thus formed nitride membrane 10 is free from uneven thickness caused by bird beak, a semiconductor element formed later by ion injection is embedded evenly to a sufficient depth. In other words, a transistor element can be formed in the molybdenum of a V-shape groove segregating region without causing thickness of a base region 5 to become thinner.

Abstract: PURPOSE:To prevent a secondary failure in a car's room air conditioner by discriminating whether the ratio of an engine rpm. and a revolution number of a cooling compressor has a certain relation or not and by indicating the engagement and disengagement control of a solenoid clutch disposed between the engine and the compressor. CONSTITUTION:By turning a switch 8 on, a discrimination circuit 3 maintains its output at L level in a certain interval so that a relay circuit 4 has one terminal of a clutch 5 grounded for electrification thereof. On the other hand, a lamp 7 is continuously lit via a lamp actuation circuit 6. After the lapse of said interval the discrimination circuit 3 estimates the ratio between both speeds of an engine and a compressor on the basis of respective output signals from an engine rpm. detection means 1A and a compressor revolution speed detection means 2A and if the ratio is estimated to be 0.8 or more, the discrimination circuit 3 maintains the L level, energizing the clutch 5 and lighting the lamp 7. If the speed ratio is reduced to below 0.8 because of a trouble of the compressor during driving, the discrimination circuit 3 is turned to H level, whereby the clutch 5 is deenergized to interrupt the compressor and the lamp 7 is made to flicker. A secondary failure may be thus prevented.
