Abstract: PURPOSE:To produce alkali hydroxide at a specified concn. with high current efficiency by electrolyzing alkali chloride in the anode chamber of an electrolytic cell with a membrane consisting of a layer contg. a specified cation exchanger on the cathode side and a specified perfluorocarbon polymer layer. CONSTITUTION:A fluorine-contg. cation exchange membrane is composed of a first layer of an alkali-proof cation exchanger having >=5mum thickness and a second layer of a perfluorocarbon polymer having 2-7% water content in 45wt.% aq. NaOH soln., >=5mum thickness and -CO2M groups (M is an alkali metal). The first layer is a porous layer of a cation exchanger contg. dispersed alkali-proof inorg. matter or short fibers, a porous layer of a cation exchange resin having low penetrability of pores or a porous layer of a cation exchanger contg. an embedded alkali-proof polymer having no ion exchange group. The cation exchange membrane is stretched in an electrolytic cell so that the first layer confronts the cathode. Alkali chloride is fed into the anode chamber of the cell and electrolyzed. Alkali hydroxide is efficiently obtd. in the wide concn. range of 20-55%.

Title: Optical information recording carriage
Inventor: HATA YOSHIO
IPC: G11B7/2585
Filed: 1985-09-12
Abstract: PURPOSE:To form a photoreflection film which is hardly corroded by the moisture in the air by incorporating an aluminum oxide into at least part of the photoreflection film. CONSTITUTION:The photoreflection film is formed by subjecting aluminum to vapor deposition or sputtering in, for example, an oxygen atmosphere, by which the metallic aluminum particles of a high temp. are partly or fully bound with the oxygen molecules in the atmosphere prior to the arrival at the signal recording surface of a substrate 11 and arrive in the form of aluminum oxide Al2O3 at the signal recording surface of the substrate 11. The aluminum oxide Al2O3 may be otherwise formed by heating the photoreflection film made of aluminum formed on the signal recording surface of the substrate 11 by vapor deposition or sputtering in the dried air to oxidize at least the surface of the photoreflection film. The photoreflection film made of the aluminum is generally as extremely thin as about 1,000Angstrom  or below and can be, therefore, oxidized easily even at a low temp. of 50-60 deg.C. The effect that said film exerts to the substrate 11 made of a resin is negligible.

Title: Variable valve system for internal combustion engine
Inventor: SANPEI KAZUHISA
IPC: B60W20/00
Filed: 1998-07-17
Abstract: PROBLEM TO BE SOLVED: To suppress the vibration of an internal combustion engine so as to prevent the generation of uncomfortable feeling to a driver at the time of an automatic stop and an automatic start of the engine. SOLUTION: A working angle is set to a maximum region by driving a lifting amount variable typed actuator when an engine is automatically stopped and automatically started (S1074). A phase difference is set to zero so that an intake valve is closed the latest by a rotation phase difference variable typed actuator at the time of driving for the automatic stop and the automatic start (S1072, S1073). The engine is automatically stopped and automatically started at a position where the closing timing of an intake valve becomes a maximum phase lag. Then, the closing timing of the intake valve deeply enters on a compression stroke, inertia supercharging is decreased, and a decomp action is generated to decrease a real compression ratio.  Therefore it is suppressed to generate the vibration in the engine and its driving force transmitting system without making the driver uncomfortable feeling at the time of an automatic stop and an automatic start.

Title: Information recording medium
Inventor: KIKUCHI IKUYA
IPC: G11B13/04
Filed: 1984-09-28
Abstract: PURPOSE:To reduce noises even if a reading spot is shifted more or less by unifying the magnetizing direction of a vertical magnetizing film into one direction of upward or downward direction and applying a magnetic field in the opposite direction to the magnetizing direction at information recording. CONSTITUTION:The vertical magnetization film 2 is formed on a base 1. An expansion of a part M corresponds to other figure. In forming the film 2 on the base 1, the magnetizing direction of the film 2 is unified into one direction, upward or downward direction (3). Then the information is erased an information recording while applying a magnetic field 4 in opposite direction to the magnetizing direction to irradiate a recording optical spot. Through the constitution above, even when the optical spot 6 is shifted a little or the diameter is increased, since the erasure part 4 having opposite magnetizing direction is read, the signal level is decreased slightly but no noise is increased.
