Patent JP-S63156368-A (JP)
Title: Semiconductor radiation detector
Inventor: ISHIYAMA OSAMU
IPC: G01T1/24
Filed: 1986-12-19
Abstract: PURPOSE:To make it possible to detect high energy radiation with a planar diode and to make it possible to detect radiation efficiently in a broad energy area, by laminating and coupling two planar diodes, and forming depletion layers in both diodes. CONSTITUTION:Incident radiation (a) reaches a depletion layer 24 through a thin p-type diffused layer 22 and also reaches a sensitive layer without much absorption. Thus alpha rays and low.energy X rays are detected. High-energy X rays transmit through the depletion layer 24 and reaches a depletion layer 15 through an n-type diffused layer 13 in the next stage. The n-type diffused layers 15 is not used for forming a p-n junction. The thickness of the layer 13 can be made thin without consideration of breakdown strength and the like. Since the radiation reaching the n-type diffused layer 13 is of the high-energy radiation, the effect of absorption is less, and the radiation is detected in the depletion layer 15. The absorbed radiation is converted into an electric signal, which can be taken out of a second electrode 3b.

Title: Optical disk reading device
Inventor: TAMAI KAZUJI
IPC: G11B7/005
Filed: 1996-11-15
Abstract: PROBLEM TO BE SOLVED: To prevent deterioration of reading performance even when an error is caused in a link block between a packet and a packet during a precedent read operation of a written packet data by discriminating whether an error block is the link block or not. SOLUTION: Data are read in each block in a specified range, and error detecting/correcting processing is performed on the read block by a decoder 12 based on an ECC(error-correcting code)/EDC(error-detecting code). As a result, when this block is not the error block, the next block is read, and if the read block has an uncorrectable error, whether this error block is the link block or not is discriminated. If the error block is the link block, this block is registered in a read error management table 14, and the read is continued to the next block, and if not the link block, the read block is nullified to stop the read operation.

Title: Increasing method for motor part pressure of motor pump
Inventor: NAKAGAWA YUZO
IPC: F04D13/06
Filed: 1991-11-21
Abstract: PURPOSE:To increase the pressure of a motor part, i.e., the pressure of circulating handling liquid, to a value higher than the suction pressure of a main process (the suction pressure of a main impeller) when a motor part is cooled and a bearing is lubricated by means of an independent circulation system for handling liquid caused to flow by means of an auxiliary impeller. CONSTITUTION:A reverse flow suction flow passage 62 extending radially outward from a suction inlet part 52 is formed in an auxiliary impeller 60 and handling liquid circulated from a front rotor chamber 34 is caused to flow to the inflow part 64 of the reverse flow suction flow passage 62. This constitution causes the increase of the pressure of the inflow part 64 (the pressure of the front rotor chamber 34) to a value higher than the pressure of the suction inlet part 52 (the pressure of a main process) by an amount equivalent to a negative pressure generated in the flow passage 62. Thus, even regarding pump handling liquid the temperature of which is increased and which is apt to gasify, circulation liquid thereof is prevented from being gasified and cooling of a motor part and lubrication of a bearing are smoothly achieved.
