Title: Method for activating hydrogen storage alloy
Inventor: YANAGIHARA NOBUYUKI
IPC: C01B3/00
Filed: 1986-11-17
Abstract: PURPOSE:To improve the safety in the activation of a hydrogen storage alloy and to reduce the number of production stages by electrochemically carrying out the occlusion and discharge of hydrogen while agitating the granular or powdery alloy for reversibly occluding and discharging hydrogen. CONSTITUTION:The electrochemical occlusion and discharge of hydrogen are carried out more than once while intermittently or continuously agitating the granular or powdery alloy for reversibly occluding and discharging hydrogen to activate the hydrogen storage alloy. The contact area with the alloy powder and the infiltration speed of hydrogen increase, as the surface area of the electrode increases. Besides, the hydrogen occluding speed is related to the equilibrium pressure of hydrogen, hence an electrolyte is cooled to reduce the equilibrium pressure of hydrogen when hydrogen is occluded, the electrolyte is heated to increase the equilibrium pressure of hydrogen when hydrogen is discharged, and hydrogen can be more efficiently occluded and discharged.

Title: Transmission line protective relay
Inventor: KONNO MASAHIRO
IPC: H02H3/34
Filed: 1999-09-28
Abstract: PROBLEM TO BE SOLVED: To provide a transmission line protective relay which can make single-phase reclosing without causing three-phase interruption, even when an interline voltage including a disconnected phase drops during single-phase reclosing no-voltage time and the pertinent undervoltage relay operates. SOLUTION: A transmission line protective relay has an accident detecting circuit, which constituted by combining directional relays DI and DO, undervoltage relays UV-1, UV-2, and UV-3, and carriers with each terminal of a transmission line and a single-phase reclosing function which only interrupts a faulty phase and again turns on a circuit breaker, after single-phase reclosing no-voltage time when a one-line ground fault occurs. The relay is also provided with a means which detects an interrupted phase, when an interrupt command is issued to the faulty phase during the single-phase reclosing no-voltage time and a means which locks the outputs of the relays UV-1, UV-2, and UV-3, including an interrupted phase by using the detected output of the interrupted phase.  When the relay is constituted in this way, one-phase interruption can be detected during the single-phase reclosing no-voltage time, and the interrupted phase can be detected from the interrupt command to the faulty phase. Therefore, single-phase reclosing becomes possible without causing three-phase interruption, because the relays UV-1, UV-2, and UV-3 which input interline voltage including the interrupted phase make unnecessary operations.

Title: Door holding detection device
Inventor: OISHI JUICHI
IPC: G01L1/00
Filed: 1995-10-23
Abstract: PROBLEM TO BE SOLVED: To detect a matter which is held from the outside of a vehicle door. SOLUTION: When a matter which is held from the outside of a vehicle between a door abutting part 9 and an entrance/exit, the matter is tried to be pulled outside of the vehicle to be detached, and the door abutting part 9 is pulled outside the vehicle. Because a fiber storage part 9e is pulled outside the vehicle through a connection part 9d, an optical fiber 12 is deformed. When the matter is held from the inside of the vehicle body, the held matter is pulled inside to be detached, and the door abutting part 9 is pulled inside. Then, the fiber storage part 9e is pulled inside the vehicle body through the connection part 9d, and supported by a regulating wall part 9f, the deformation of the optical fiber 12 is regulated.  Because the transmitted light quantity of the optical fiber is changed as the held matter is pulled outside or inside the vehicle body, it can be detected that the matter is held from the outside the vehicle body by detecting the light quantity.

Title: Piping of cooling system
Inventor: IMAI SEISHI
IPC: F25B39/02
Filed: 1992-10-13
Abstract: PURPOSE:To prevent a sudden change in the pressure of a heating medium by a method wherein the opening face of a capillary tube on the exit side of the heating medium is cut obliquely to the direction of the axis of the tube. CONSTITUTION:On the occasion when a heating medium A flowing through a capillary tube 11 is discharged into a joint pipe 12, it passes through the opening face 11a on the exit side of the capillary tube cut obliquely to the center line 14b of the capillary tube. Since the opening face 11a on the exit side of the capillary tube is cut obliquely to the center line 14a of the pipe according to this constitution, expansion of the section of the heating medium A becomes gentle on the occasion when it is discharged into the joint pipe 12. Accordingly, a sudden drop of the pressure of the heating medium A can be slowed down and a turbulent flow in the joint pipe 12 can be suppressed. Therefore the flow of the heating medium A becomes stable and generation of a sound of the heating medium can be reduced.

Abstract: PROBLEM TO BE SOLVED: To manufacture a semiconductor device, wherein the particles attached on the surface of a semiconductor substrate in the manufacturing process of the semiconductor device are inspected with high reliability and high sensitivity, and the defects of the elements that are considered supposedly that the particles are the cause are prevented. SOLUTION: An epitaxial growing layer 2 of a silicon single crystal is formed on the surface of a silicon wafer 1, formed by a CZ method and a FZ method. Under a state wherein the surface is polished, the laser beam of a laser light source 11 is projected. A particle 3 is inspected by detecting the scattered light by light-receiving parts 12a-12d. A COP 4 at the surface of the silicon wafer 1 is eliminated by the epitaxial growing, and mis-detection of the particles can be prevented. By polishing the surface of the epitaxial growing layer 2 again, haze caused by the micro-roughness of the surface of the silicon wafer can be prevented. Furthermore, even when the laser light is projected in a direction of 90 deg. with respect to the surface of the silicon wafer 1, the particle 3 can be detected with high reliability.  Furthermore, the optical intensity of the scattered light is enhanced, so that the detection sensitivity can be enhanced.
