Title: Manufacture of semiconductor device
Inventor: IMAI MASATOSHI
IPC: H01L21/316
Filed: 1979-03-13
Abstract: PURPOSE:To eliminate lateral expansion of an oxide film on the semiconductor layer formed on a sapphire substrate in a semiconductor device by selectively implanting oxygen ion, heating and oxidizing the semiconductor layer to form the oxide film for short time when isolating an SOS oxide film. CONSTITUTION:A monocrystalline silicon layer 2 is grown on a sapphire substrate 1, an SiO2 film 3 and an SiN film 4 are sequentially formed on the layer 2, and an opening 5 is formed thereon. After the exposed silicon layer is slightly etched, oxygen atom is ion implanted thereon to form an implantation region 12. Then, the region 12 is heated to form an isolating SiO2 layer 13 in the ion implantation region 12. The layer 13 is heated in oxygen atmosphere to simultaneously oxidize the surface of the silicon layer. Since the oxidation is thus proceeded from the interior of the silicon layer, it can shorten the time required for the oxidation so as to eliminate the lateral expansion of the oxide film. Accordingly, it can form an isolating oxide film of infinitesimal structure.

Abstract: PURPOSE:To transmit again a document from a position interrupted by communication abnormality and to shorten a transmission time by exchanging a block signal, which can be identified, added to a data signal for each scanning line. CONSTITUTION:A number addition part 3 outputs a data signal (d), to which the block number is added in a leading part as one block for each scanning line to an encoding signal (b) from an encoder 3, to a memory circuit 4. A communication control part 5 sends a successively read data signal (e) from the memory circuit 4 and recognizes the block number, to which reception is completed, to be returned from a reception side with a prescribed interval time during one time of communication. Then, the detection of the block number is executed until the final number. A communication control part 6 writes the received data signal and block number added to this signal to a memory circuit 7 samely as a transmission side and returns the received block number to the transmission side with the prescribed interval time. Thus, when the document original is transmitted again, it is enough to execute the transmission from the data signal of the not-reached block number and the transmission time can be shortened.

Abstract: PURPOSE:To obtain a magnetic bearing controlling method and a device thereof, wherein proof stress of the magnetic bearing is improved by decreasing resonance amplitude of unbalance vibration of revolution synchronization, and also decreasing electric current to flow in the electromagnetic coil of the magnetic bearing. CONSTITUTION:Rotation synchronous components Xn, Yn multiplied by proportional coefficient delta given by coefficient multipliers 23X 23Y are added to outputs of control circuits 4X, 4Y. The purpose is to increase the spring constant, accordingly the resonance point is shifted in the higher direction. Vibration can be decreased by shifting the resonance point to the higher revolutions in the revolution range just before the resonance point. Taking of the coerfficient is the method for restraining the resonance amplitude, and is effective only in critical speed passing. After the critical speed is passed to a considevable entent, this methol is no more needed, but the control of only ABS is desired. Accordingly, when the values of the proportional coefficient alpha, beta are selected according to the revolution range, the most-effective control wherein controlled electric current is minimum in the whole revolution range is made possible.
