Title: Multiple core nb3sn superconducting cable for alternating current
Inventor: DAIMATSU KAZUYA
IPC: H01B12/10
Filed: 1990-11-22
Abstract: PURPOSE:To make filament diameter less than a micrometer and reduce alternating current loss by making the filament diameter 1mum or less and making the distance between filaments 70%-150% of the filament diameter. CONSTITUTION:A primary stack 5 comprises a Cu or Cu alloy matrix 7 in which a plural number of Nb filaments 8 are held together. They are so arranged that the filament diameter is 1mum or less and the distances between the filaments are from 70% to 150% of the filament diameter. The small filament diameter reduces hysteresis loss while the filament to filament distance 70%-150% of the filament diameter prevents the Nb from deforming in the shape like ribbons and prevents the filaments from coming into contact with each other at the time of heat treatment for forming Nb3Sn not to increase hysteresis loss. Also the share of Nb3Sn increases so that a large current density per wire can be taken. This provides a multiple core Nb3Sn superconducting cable of the filament diameter less than a micrometer and of a reduced alternating current loss.

Title: Nuclear reactor shut-down device
Inventor: HARADA KIYOSHI
IPC: G21C7/14
Filed: 1987-12-21
Abstract: PURPOSE:To spontaneously and rapidly shut-down a nuclear reactor for an event of rising of a coolant temp. by using a temp. sensing alloy to constitute the entire circumference of the outer side of either of an armature part or magnet part. CONSTITUTION:A magnet iron core 3 made of a magnetic material and an electromagnet 6 constituted of a coil 2 are mounted to the bottom end of a driving extension shaft 1 which is vertically driven by a control element driving mechanism. On the other hand, an iron core material 5 and the armature 7 constituted of the temp. sensing alloy 4 which encloses the outside circumference of said material are mounted to the top end of a connecting shaft 8 which hangs the control element. Since the temp. sensing alloy 4 is mounted over the entire circumference on the outer side of the armature 7, the alloy comes into direct contact with the coolant flowing on the outside of the structure and is capable of rapidly responding the temp. change of the coolant. If it is assumed here that the core temp. rises by any cause and the temp. of the sensing alloy 4 attains the Curie point, then the magnetic resistance over the entire part of the magnetic circuit increases and, therefore, the coercive force of an electromagnet 6 decreases to drop the control element. The reactor is thus shut-down.

Abstract: PROBLEM TO BE SOLVED: To make positioning accuracy of a process cartridge to an image forming device main body possible to be improved. SOLUTION: This image forming device is allowed, to make a bonded surface 156 of a cleaning frame body cap 13p and the cleaning frame main body 13q, the surface of the cartridge control contact part 13e, and a positioning center P of the cap 13p and the main body 13q so as to pass through the same point in the case of viewing it from a side plane. In such a manner, the device is free from manufacturing error arising as a result of the contact plane located parting from the positioning part, free from dimensional error along the contact plane between a first frame body and a second frame body, and free from the manufacturing error occurring as a result of a wide gap between an extension plane on a control contact part and the positioning part, in consequence that the extension plane on the control part and the positioning part are crossing the same point as above.  Accordingly, the position of the control contact part on the first frame body is accurately fixed with respect to the first frame body. Therefore, the positional accuracy of a posture of the process cartridge with regard to the image forming device main body can be improved.
