Title: Vapor phase epitaxy device
Inventor: NANBARA SEIJI
IPC: H01L21/205
Filed: 1989-04-26
Abstract: PURPOSE:To make a stable semiconductor crystal grow by providing an insulator that is opaque to infrared and far infrared rays, i. e., an inner tube (the 2nd reaction tube) made of SiC, to the inside of a reaction tube (the 1st reaction tube). CONSTITUTION:Decomposition and reaction of heating of a raw gas that is introduced into the 1st reaction tube 2 from the inlet 1 of the raw gas take place in the vicinity of a substrate 3 which is heated by a susceptor 4 and RF coils 18 and its gas is deposited as a crystal on the substrate 3. Simultaneously with an epitaxial growth, sticking substances are deposited to the inner wall of the 2nd reaction tube 10 as well. As the 2nd reaction tube 10 is formed in advance with an insulator that is opaque to infrared and far infrared rays in the same way of the sticking substances, its reaction tube 10 absorbs almost all of the infrared and far infrared rays that are radiated from the susceptor 4. The amount of the infrared and far infrared rays that are absorbed by the 2nd reaction tube 10 does not change irrespective of the deposited quantities of the sticking substances and no thermal system in the 2nd reaction tube 10 varies at all. Then, a crystal growth that is stable at all times is performed.

Title: Grappling machine provided with submarine cable holding and cutting functions
Inventor: EJIRI YOSHIHIRO
IPC: H02G1/10
Filed: 1990-04-23
Abstract: PURPOSE:To see that the check valve for low pressure withstands high pressure and that the check valve for low pressure does not cause leakage at low pressure by providing it with a piston, which puts the valve in open condition receiving the sea water flowing in, and a return coil, which puts the valve in closed condition when the pressure inside a piston cylinder mechanism for operation of a cable holding and cutting mechanism becomes equal to the sea water pressure. CONSTITUTION:When sea water of high pressure presses down a piston 20, injection orifices 13 and 25 and the inside of a cylinder 4 communicate with each other, and sea water flows in the cylinder 4. At the same time, the sea water from the injection orifices 13 and 25 also flows in a cylindrical 22. And when the sea water pressure inside the cylinder 4 and the cylinder 22 becomes equal to the sea water pressure outside a grappling machine A, the piston 20 is pushed up to its place by a return coil spring 21. Therefore, the sea water injection orifice 25 and a communication orifice 26 are shut off, and the inside of the cylinder of the grappling machine body 2 is sealed and kept at high pressure.

Title: Fuel injection timing controller of internal combustion engine
Inventor: SUZUKI MAKOTO
IPC: F01L1/34
Filed: 1993-05-07
Abstract: PURPOSE:To prevent generation of deposits and damage of a fuel injecting means caused by backflow of exhaust gas. CONSTITUTION:A VVT 23 adjusts continuously the opening/closing timing of an intake valve 9 by driving of a step motor 25. When the intake valve 9 is opened/closed on the most delay side, the basic start timing and the basic end timing are respectively set as the target start timing and the target end timing. When the VVT 23 is drive-controlled and also when the intake valve 9 is opened/closed on the spark advance side, the values obtained by respectively subtracting displacement angles from both basic timings are set as the target starting timing and the target end timing. Accordingly, fuel injection is completed before the opening regardless of the opening timing of the intake valve 9, thereby the opening timing of the intake valve 9 is not overlapped on the fuel injection timing. Therefore, fuel remaining in the intake valve 9 is suitably vaporized by backflow of exhaust gas when the intake valve 9 is opened, even though the valve overlap amount is increased.

Abstract: PROBLEM TO BE SOLVED: To form a high-quality buried oxide film while the occurrence of slips and the contamination of the film by an impurity are reduce by implanting oxygen ions into the main surface of a silicon substrate containing carbon at a specific concentration or higher and performing heat treatment on the substrate by annealing. SOLUTION: After positively charged oxygen ions 2 are implanted into a silicon substrate 1 containing carbon at a concentration of over 2×10<-16> cm<-3> with acceleration energy of 180 keV, oxides 3 are uniformly formed in the substrate 1 through heat treatment by performing annealing on the substrate 1 at 1,000 deg.C in a heat-treating furnace. Then, the growth of the oxides 3 is promoted by accelerating the precipitation of oxygen by raising the heat-treating temperature to 1,100 deg.C. In addition, a buried oxide film 4 having a uniform thickness is formed by eliminating silicon pipes by combining the oxides 3 into one. Therefore, a high-quality buried film 4 can be formed through low- temperature heat treatment and the occurrence of slips and the contamination of the film by an impurity can be reduced.
