Title: Dielectric isolation substrate and its manufacture
Inventor: SHIRASAWA TOSHIKATSU
IPC: H01L21/76
Filed: 1989-06-02
Abstract: PURPOSE:To enhance production yield of a substrate and to reduce a production cost by providing the following: a single-crystal Si group which has been insulated and isolated by an isolation groove and an insinuator; a vertical-type single- crystal region which has been pierced from the surface to the rear of the substrate and which is not insulated and isolated. CONSTITUTION:This is a substrate in which an n<+>-buried layer has been formed partially in a vertical-type single-crystal region 160. That is to say, the following have been united: a single-crystal island 150 in which a single-crystal Si region composed of an n<->-layer 110 and an n<+>-buried layer 130 has been insulated and isolated electrically by an oxide film 140; and the vertical-type single-crystal region 160 which is composed of the n<+>-layer 110, the n<+>-buried layer 130 formed on a slope and an n<++>-high-concentration epitaxial layer 161. Thereby, a buried layer can be formed partially without adding a new photomask and a new process. ln addition, a mechanical shook is not exerted on a wafer where an isolation groove has been formed; consequently, the production yield of substrates can be enhanced.

Title: Solar cell
Inventor: MITSUI KOUTAROU
IPC: H01L31/0735
Filed: 1981-09-03
Abstract: PURPOSE:To obtain the solar cell having high efficiency by adjoining N type GaAs to a low density layer between two adjacent P type GaAs having different hole density. CONSTITUTION:Even when the P type GaAs layers 8, 9 are stacked onto an N type GaAs layer 1, a P type AlGaAs layer 4 is stacked and the decrease of recombination is intended, the recombination of carriers is generated on the interface of the layers 9, 4. When the layer 9 is made higher and the layer 8 lower in the hole density and the stage difference DELTAE of energy is formed on the interface, the interface is connected by the two GaAs, and differs from the interface between the layers 9, 4, and the recombination of carriers on the interface reaches approximately zero. Consequently, when DELTAE>kT is formed and the thickness of the P layer 8 is shorter than the diffusion length of electrons, electrons injected from the N layer 1 diffuse up to the interface between the layers 4, 9, and its recombination can be prevented. Accordingly, the leakage of a P-N junction 3 is reduced, and the cell having large opening end voltage and curve factor and high efficiency is obtained. When the difference of three times or higher is formed in hole density, DELTAE>kT is formed, and an effect is displayed.

Abstract: PURPOSE:To prevent a transmitting system from being broken down extending over many hours by providing independently the second output abnormality detector, in addition to the first output abnormality detector attached to the first automatic control device used as the existing system. CONSTITUTION:Now, it is supposed that a fault is generated in the first output abnormality detector 6 or the first automatic control device 7, a fault generated in the first transmitter 1 used as the existing one cannot be detected, and switching to the second transmitter 2 which is held as a stand-by one is executed automatically, in spite of an abnormality of an output.

Filed: 1981-09-08
Abstract: PURPOSE:To increase the rate at which mixture gas of refrigerant gas and freezer oil flows into a shaft by using as bypasses of refrigerant gas return passages for it which intersect suction gas passages formed on the periphery of a cylinder. CONSTITUTION:Refrigerant gas return passages 10 which are formed as to encircle the periphery of a cylinder 1 intersect suction gas passage 4 which are shaped in the lengthwise direction of the cylinder 1 and cored holes 5. If mixture gas flows into a shaft 6, the mixture gas runs through friction parts for separation into refrigerant gas and freezer oil. The refrigerant gas flows through the return passages 10 and is returned to the suction passages 4 while the freezer oil is deposited in a storage part 9 at the bottom of the cylinder 1 to provide complete lubrication. The bypass passages for the refrigerant gas and the freezer oil may be therefore ensured so that the rate at which the mixture gas of the refrigerant gas and the freezer oil flows into the shaft 1 may be increased.

Filed: 1989-06-01
Abstract: PURPOSE:To confirm characteristics after semiconductor integrated circuit adjustments before a fuse blows by turning on or off the 2nd transfer gate, which is connected to the 1st transfer gate in parallel, with a control signal. CONSTITUTION:An input terminal 1 enters a test mode with a high level and an input terminal 2 inputs a high-level signal when a fuse is disconnected in the test mode by fuse selection. The terminal 1 is at a low level except in the test mode, so a transfer gate 4 turns on and terminals 5 and 6 are determined according to the state of the fuse 7. When the terminal 1 is held at the high level to enter the test mode, the gate 4 turns off and when the terminal 2 is at the low level and the fuse is not selected, a transfer gate 3 turns on to enter a state wherein the fuse 7 is considered to be connected. When the terminal 2 is at the high level and the fuse is selected, the gate 3 turns off to enter a state wherein the fuse is considered to be disconnected. The terminal 1 is pulled down and enabled to operate when not used without applying a signal to the terminal 1.
