Title: Hydrogen gas leakage monitor of turbine generator
Inventor: SOMA SHOHEI
IPC: G01M3/20
Filed: 1995-11-06
Abstract: PROBLEM TO BE SOLVED: To make it possible to monitor leakage of hydrogen accurately all the time without the effect of the fluctuation of the temperature of cooling water accompanying the magnitude of the load of a generator by providing a cooling-water temperature regulating valve, a cooling-water cooler and a bypass pipe in an external outflow system. SOLUTION: The cooling water in a water storage tank 2 is discharged with a pump 3 and its pressure is regulated by a pressure regulating valve 7. The water is supplied to a turbine generator 1. The cooling water is discharged into a cooling-water returning pipe 9 after cooling a stator winding and branched to a cooling-water cooler 4 and a bypass pipe 6, then mixed and temperature-regulated in a cooling-water-temperature regulating valve 5, and is recovered into the water storage tank 2. Though hydrogen gas, which is the cooling medium of the generator 1, is dissolved into the cooling water and leaking, the hydrogen gas is separated in the water storage tank 2 and discharged to the atmosphere from a discharging pipe 10. At the discharging pipe 10, a hydrogen gas detector 11 measures and monitors the amount of hydrogen gas.  The temperature of the cooling water at the time of discharging is not constant by the load change of the generator. However, the temperature is regulated at the constant value by the cooler 4 and the temperature regulating valve 5, and the volume of the cooling water in the water storage tank 2 is not changed.

Title: Magnetic recording medium and its manufacture
Inventor: NAHATA YOSHIYUKI
IPC: G11B5/84
Filed: 1994-11-21
Abstract: PURPOSE: To lower the friction coefficient at the surface by forming a lubricant layer of a polymer of a compound expressed by a specific formula and oxygen, and constituting the lubricant layer of a fixed layer sticking to a protecting layer and a free layer formed on the fixed layer. CONSTITUTION: In forming a lubricant layer 15, in a first process, a vapor-phase polymerization is conducted under vacuum to polymerize a compound expressed by CF2 =C(Rf)(R'f) and oxygen. In a second process, after steam is introduced, a vapor-phase polymerization is carried out under vacuum thereby to polymerize the compound expressed by the formula and oxygen sequentially. (In the formula, Rf and R'f indicate a hydrogen atom, fluorine atom, perfluoroalkyl group, perfluoroalkenyl group or partially fluorinated aryl group.) The layer 15 forms a fixed layer 15a having polymer molecules sticking to the surface of a protecting layer 14 by chemical bonding, and a free layer 15b on the layer 15a. Because of the presence of the layers 15a, 15b, the polymer molecules remain after the medium is cleaned, so that the friction coefficient at the surface of the medium is lowered.

Title: Semiconductor device
Inventor: IDE SATOSHI
IPC: H01S5/00
Filed: 1992-10-26
Abstract: PURPOSE:To enable the structure of suppressing the diffusion of acceptor impurities from a p-type layer to a low-impurity concentration active layer, by using the p-type layer contained especially in acceptor impurities, concerning a III-V compound semiconductor device. CONSTITUTION:A group III-V compound semiconductor layer 11 performing capture action of acceptor impurities is made on the p-type semiconductor layer 10 of group III-V compound containing acceptor impurities. A III-V compound semiconductor active layer 13 low in impurity concentration is made on this semiconductor layer 11. That is, the diffusion of impurities from a substrate 10 to the active layer 13 is suppressed by the acceptor impurity capture action of the III-V compound semiconductor layer. The diffusion capture action is brought about by the mutual action between lattice defect and acceptor impurities. Accordingly, if capture regions are provided in a plurality of sections, the influence of diffusion to the active layer 13 can be controlled more effectively.

Title: Position detecting device
Inventor: MAEJIMA HIDEO
IPC: G01B7/00
Filed: 1992-10-26
Abstract: PURPOSE:To reduce the burden on an adjustment part by sampling the sampling pulse, of which phase is shifted at 180 degree, in one of two sample hold circuits, and adding the signal of both the circuits after the sampling to cancel the DC off-set due to a high frequency component. CONSTITUTION:A phase shifter 3, a sample hold circuit 8 and an adder 6 are added to a conventional position detecting circuit. The phase shifter 3 shifts the phase of the sampling pulse at 180 degree, and the sample hold circuit 8 performs the sampling of the balanced modulation signal hs' with the output of the phase shifter 3 as the sampling pulse. The adder 6 adds both the signals Hs, Hs' after the sampling by the sample hold circuits 7, 8 to obtain the output signal S, from which is cancelled by a DC off-set. With this output signal S, relative displacement quantity between a scale 10 and a detecting head 9 can be detected. Since the DC off-set due to a high frequency component is eliminated, the burden on the adjustment part at the later stage is reduced.
