Patent JP-S63106457-A (JP)
Title: Screw actuator
Inventor: PIEERU EMU JIENEKUWAN
IPC: B23Q5/40
Filed: 1987-10-14
Abstract: In an actuator, a carriage coupled to an item to be displaced with a translatory movement comprises a follower element which defines contact surfaces engaged against the flanks of the thread of a micrometric screw. The contact surfaces co-operate with the thread of the screw only over a small angular portion thereof. The follower element of the carriage is held on the thread of the screw by resilient thrust means acting on the carriage so as to urge it pivotally about an axis (X-X) which is parallel to its direction of translatory movement, being prevented from moving in all the other degrees of freedom. The actuator is especially adapted for use in translator devices in which the level of precision is of the order of a micrometer.

Abstract: PURPOSE:To generate high-accuracy position information even when a low- voltage power source is used by compensating the base-emitter voltage of transistors(TR) for rectification by using the output of a rectifying circuit. CONSTITUTION:The base bias voltage VBB of the TRs Q2 and Q3 for rectification is varied by using the output (collector or emitter voltage of TRs Q2 and Q3) of the rectifying circuit 21 to compensate the VBE of the TRs Q2 and Q3.

Title: Method for treating cladding tube waste and for supplying electricity in nuclear power plant
Inventor: IKENAGA YOSHIAKI
IPC: G21F9/30
Filed: 1998-09-14
Abstract: PROBLEM TO BE SOLVED: To simultaneously solve two problems-the pollution with radioactivity and the stable supply of electricity-by reclaiming a cladding tube waste (hull) of a spent nuclear fuel as a hydrogen-occluding alloy, storing the hydrogen produced by surplus power in the alloy and using it for the generation of power. SOLUTION: As a hull is a zircalloy, an appropriate composition is made by adding Fe and the like to it, is melted by high-frequency waves and is hardened. After the hull is crushed under an atmosphere of an inactive gas and the surface of it is conditioned by a dilute acid and the like, it is cleaned and dried and is contained in microcapsules to recover a hydrogen-occluding alloy. In the meantime, water is electrolyzed to produce hydrogen by using surplus night power involved in a nuclear power plant and the hydrogen is stored by using the hydrogen-occluding alloy that was recovered earlier till it is emitted in the daytime. Though the method of power generation is not limited to a fuel cell, it has a proven performance in the use of a small scale.  Though the recovered hydrogen-occluding alloy requires the shielding from radioactivity, notably, it is easy to solve the problem because the alloy is used only in a nuclear power plant.
