Title: Semiconductor laser
Inventor: KOMAZAKI IWAO
IPC: H01S5/00
Filed: 1991-04-01
Abstract: PURPOSE:To avoid an increase in a threshold value current by partly removing an active layer through a region into which Ga<+> ions are implanted, disposing an electrode on the surface of a current block layer in which a lower clad layer and the block layer are conducted and providing an end face perpendicular to a resonator direction and a 45-degree mirror surface. CONSTITUTION:A semiconductor laser has a semiconductor laser region A, a photodetector region B and an isolating region C for isolating the regions A, B. Since carriers injected by a p-type electrode 18 are injected only into the central part of a mesa since both sides of the mesa become Ga<+> ion implanted regions (high resistance regions) 17 where Ga<+> ions are implanted. Light generated by recombination of the carriers in an active layer is efficiently repeatedly fed back on both end faces, reflected from a 45-degree mirror toward a surface of a wafer. The region A and the region B are the high resistance regions where Ga<+> ions are implanted to be electrically completely isolated, thereby reducing a leakage current.

Abstract: PURPOSE:To eliminate the recess of a contacting hole due to sidewise etching by forming insulating films of a plurality of different etching speeds on a substrate when forming the contacting hole in a semiconductor device, and gradually reducing the etching area of the insulating films. CONSTITUTION:A thermally oxidized film 13, a PSG film 14 and a CVD oxidized film 15 are laminated on a semiconductor substrate 11, the first photoresist film 16 having a hole corresponding to an element region is covered thereon, and the exposed part of the film 15 is first removed with hydrofluoric acid-base etchant. Then, the film 16 is removed, the second photoresist film 17 is newly formed in such a manner to be reduced in the hole approx. 5mum smaller than the film 16, and the surface of the film 14 is covered at the end of the hole. When the films 14, 13 are thereafter etched with similar etchant, the etching speed of the film 14 is faster. Even if side etching according occurs remarkably, the film 15 is etched widely approx. 5mum. Thus, the sidewise etching does not exert to the lower part of the film 15. Accordingly, it can obtain a hole of conical shape, and can avoid the disconnection of the electrode.

Title: Double structure check valve for gas engine with auxiliary chamber
Inventor: YASUEDA SHINJI
IPC: F02M21/02
Filed: 1995-03-03
Abstract: PURPOSE: To prevent a check valve from sticking caused by carbon, by furnishing a needle type and a ball type check valve which open only when the intra- cylinder pressure lies low and close when high so that the combustion gas is precluded from counterflowing, and locating the ball type check valve on the side of an auxiliary chamber. CONSTITUTION: A double structural check valve 1 is composed of a ball type check valve 2 and a needle type check valve 3, wherein the ball type check valve 2 is located on the side with an auxiliary chamber 4, and the whole construction is attached to a metal fixture 5 which houses the auxiliary chamber 4. When this engine, i.e., a gas engine of rubbish burning aux. chamber type, is in the supply and exhaust strokes, the combustion gas opens the two check valves 2, 3 and flows into the aux. chamber 4. When the intra-cylinder pressure rises in the compression stroke, the check valves 2, 3 are immediately closed one by one. Then the residues of combustion gas are willing to counterflow from inside the cylinder in the combustion process, but because the ball type check valve 2 shields carbon, the needle type check valve 3 is precluded from sticking with the carbon.
