Title: Apparatus for manufacturing amorphous solar battery
Inventor: SASAKI HAJIME
IPC: H01L31/04
Filed: 1989-03-08
Abstract: PURPOSE:To make hydrogen easy to couple with Ge to obtain good amorphous silicon germanium by a method wherein laser light for selectively exciting atomic vibration of hydrogen and Si is radiated into a film. CONSTITUTION:Reactant gas 5 is fed through a gas feed system 6 into a reacting vessel 1 and gas is exhausted from an exhaust system 7 so that the gas pressure in the reacting vessel 1 is a specified value in the range of several Torr to several milli Torr. Then high frequency is applied to an electrode 3 from an external high frequency power source 4 to have plasma generated between the electrodes 3 to decompose the reactant gas. Decomposed gas is accumulated on a substrate 4 to form an amorphous film. By radiating laser light in an infrared region to the surface of the film, atomic vibration of Si and hydrogen is excited to cut off the coupling thereby increasing probability of Ge to couple with hydrogen. Good amorphous silicon germanium can be thus obtained.

Abstract: PURPOSE:To improve the efficiency of a large capacity memory system by counting the using frequencies of cartridges, and storing cartridges of high using frequencies into a cell set near a data recorder and the cartridges of low using frequencies into a cell distance away from the data recorder. CONSTITUTION:For a cartridge control program 13, a cartridge optimum distribution function program 15 selects an entry E having the smallest value of a time column and showing an idle state out of a cartridge control table 14 in case a request given from an upper device is equal to a cartridge application request. Then a cartridge identifier is written, and at the same time the value of a cell address column is informed to the program 13. The program 13 sends the cell address and the application request to a cartridge access program, and the applied cartridge is stored into a selected cell. Thus it is possible to reduce the time needed for read/write of cartridges of high using frequencies. In such a way, the using efficiency of a large capacity memory system is improved.

Title: Correcting information of information
Inventor: MATSUURA HIDEO
IPC: G06F11/10
Filed: 1983-03-31
Abstract: PURPOSE:To reduce the average time up to a time point when the correction of information is impossible down to half compared with a case where a simple forward shift is used by a comparatively simple circuit, by using an adverse polynomial to a grown polynominal using a fire code when a burst error is corrected and then performing a reverse shift. CONSTITUTION:A grown polynomial C(x) is used for production of ECC and decoding, and an adverse polynominal of G(x) is used when an error position is detected to decide the incapability of error due to the generation of a burst error. A reverse shift is carried out from a position of a bit 47 of a shift register 102. Therefore the error pisition is retrieved from the terminal of a code. This needs no retrieval for retrieval of ''0'' of (27586-N) bytes which exists virtually at the head of the code. Thus it is decided that the correction of error is impossible if all bits from O to 43 of the register 102 are not turned into O with a shift equivalent to (NX8) bits. As a result, the shift frequency is reduced down to half of (27586X8) times when a burst error is corrected at a data part of variable length which is recorded in a variable length format.
