Title: Magnetic type position sensor
Inventor: OHASHI KYOSUKE
IPC: G01B7/30
Filed: 1996-04-23
Abstract: PROBLEM TO BE SOLVED: To provide a magnetic type position sensor which can accurately compensate for changes in the resistance value of a magnetoresistive element attributed to temperature changes in a magnetic type position sensor having the magnetoresistive element. SOLUTION: A magnet 13 is fixed on a rotor 12 and a flexible substrate 14 with GMR elements (giant magnetoresistive elements) 16 and 17 filmed are arranged on the perimeter of the rotor 12. The area on which a magnetic field from the magnet 13 acts varies with the rotation of the magnet 13 for the GMR element 17, and it is so constituted as to always be constant with respect to the GMR element 17. Therefore, as the rotor 12 rotates, the resistance value of the GMR element 16 varies according to the angle of rotation, whereas the resistance value of the GMR element 17 does not. Thus, the rotating position of the rotor 12 is detected based on the resistance values of the GMR elements 16 and 17, thereby enabling compensation for changes in the resistance value of the GMR element 16 attributed to temperature changes.

Title: Chromium-chlorine secondary battery
Inventor: FURUYA CHOICHI
IPC: H01M12/08
Filed: 1989-04-21
Abstract: PURPOSE:To make unnecessary both the use of a diaphragm and the separation and regeneration of electrolyte by using as anode a gas diffusion electrode that contains a reaction layer carrying platinum group elements and a gas diffusion layer, and using a hydrochloric acid water solution of chromium as electrolyte. CONSTITUTION:A gas diffusion electrode is used as anode. As the gas diffusion electrode one which contains a reaction layer and a gas diffusion layer is used. The electrolyte is a hydrochloric acid water solution of chromium ie. a water solution of first chromium chloride or second chromium chloride. Thus the reaction layer of the gas diffusion electrode absorbs chlorine ions during charge that exit by a large amount in the electrolyte and the ions ahsorbed are taken out of an electrolyte vessel through the gas diffusion layer, and so a large amount of chlorine ions are promptly converted into chlorine gas, while a large amount of chlorine gas is promptly converted into chlorine ions during discharge. Moreover, since only one kind of hydrochloric acid water solution of chromium is used as electrolyte, the use of a diaphragm is unnecessary and so efficiency lowering is prevented that may be caused by the use of a diaphragm.
