Title: Method for electrolytically refining and purifying titanium
Inventor: TAKAHASHI SETSUKO
IPC: C25C1/06
Filed: 1988-05-18
Abstract: PURPOSE:To directly obtain metallic Ti at a low temp. by electrolyzing a eutectic mixture of a titanium halide forming a molten salt bath even at ordinary temp. with an insoluble electrode as the anode while replenishing the titanium halide as raw material to be refined. CONSTITUTION:50-80mol% titanium halide is mixed with 20-50mol% N- alkylpyridinium halide represented by a formula C5H5N-RX (where R is 1-4C alkyl and X is halogen), an org. solvent is optionally added to the mixture and a molten salt bath is formed. This salt bath is electrolyzed with an insoluble electrode as the anode while replenishing the titanium halide as raw material to be refined. By the electrolysis, Ti is electrodeposited on the cathode and Ti refining is carried out. A halide of a metal other than Ti and/or about 10-75vol.% org. solvent is preferably added to the salt bath. The electrolysis is preferably carried out with DC or pulsating current at about 0-150 deg.C bath temp. and about 0.1-100A/dm<2> current density in a dry oxygen-free atmosphere.

Abstract: PURPOSE:To enable assembling of a rotation body which is an integral molding to a cylinder by cutting off a part of a section which is other than a movable wall of an end part of the revolution body and overlaps with a convex part of the cylinder viewed from the axial direction. CONSTITUTION:In a rotation body 8, a section which is other than a movable wall 8c of one end of a valve body 8a and overlaps with a convex part 1b of a cylinder viewed from the axial direction of the rotation body 8 is cut off.

Title: Memory device
Inventor: OZAWA KOUJI
IPC: G11C11/409
Filed: 1979-09-21
Abstract: PURPOSE:To eliminate charge unbalance between digit lines by setting the absolute threshold level of MISFET, selecting a connection between two digit lines, lower than the threshold level of each digit line precharging MISFET. CONSTITUTION:The absolute threshold level of MISFETQ33 making a selective connection between digit lines D1 and D1' is set much lower than the threshold levels of precharging MISFETs Q31 and Q32 connected to FETQ33 at gates in common. As a result, as precharging voltage P rises, only FETQ33 conducts firstly to hold nodes N31 and N32 of lines D1 and D1' at the same potential. Next, as voltage P rises further, nodes N31 and N32 are charged without unbalance according to differences in threshold level between the above-mentioned voltage and FETs Q31 and Q32 even if threshold levels of FETs Q31 and Q32 vary slightly because FETQ13 stays ON, so that the memory unit will increase in sensitivity.
