Title: Preparation of liquid crystal display device
Inventor: HASEGAWA SATOSHI
IPC: G02F1/1337
Filed: 1986-03-18
Abstract: PURPOSE:To make the direction f orientation uniform when a liquid crystal display device is constructed by arranging toward inside the orientation layers of a pair of substrate prepd. by building a transparent electrode and an orientation layer, and inserting liquid crystals therebetween, by constituting the orientation layer of a polymer film, back sputtering the surface, then rubbing in a fixed direction using cloth, etc. CONSTITUTION:Resin film having ca.300Angstrom  thickness is prepd. by coating polyimide type polymer resin on a substrate 1 through a transparent electrode, and then heat-treating. Then, the surface of the resin film is subjected to back sputtering with pref. several hundreds W - several KW power to form fine unevenness on the surface. Thereafter, the surface is rubbed with bleached cotton cloth, etc., in a fixed direction under several kg - one hundred and several kg total pressure to prepare orientation film 2 having directionality by grinding the unevenness toward one direction more heavily than toward the opposite direction. By this method, regulation of the pretilt angle to 0-30 deg. is facilitated, and uniform orientation may be attained even if the twist angle of the liquid crystal molecule is enlarged to >=90 deg..

Inventor: NAKAJIMA HIDEKI
IPC: F16H63/50
Filed: 1996-02-21
Abstract: PROBLEM TO BE SOLVED: To control shift position in compliance with the actual road gradient. SOLUTION: The road gradient given by a navigation device is fed to the system (S10), and a traveling resistance is calculated from the road gradient and the present car speed (S16). The engine speed and torque at each shift position in an automatic transmission concerned are calculated (S24), followed by selection (S28) of a shift position which generates the engine speed and torque obtained from calculation with the least rate of fuel consumption. The changing-over is made (S30) into the selected shift position. This allows controlling the shift position so that the least rate of fuel consumption is endured in accordance with the traveling resistance which is noy measurable directly.

Filed: 1990-03-13
Abstract: PURPOSE: To produce a desired product at the max. weight ratio by measuring the IR absorption ratio of a reaction mixture to be charged, comparing the same with an optimum reactant IR absorption ratio, measuring the reactant weight ratio before heating of the reaction mixture and correcting the weight ratio. CONSTITUTION: The IR absorption ratios of the functional groups of the respective reactants and the product are first measured at the time of producing an alkenyl succinimide ORI control additive by allowing an polyethoxy polypropoxypolybutoxy diamine to react with an alkenyl succinic anhydride. This ratio and the IR absorption ratio of the optimum reactant are compared and a first curve is plotted by associating the ratio with the weight ratio of the reactant. Next, the weight ratio of the reactant is changed by a small-scale mimic reaction and a second curve is plotted by associating the IR absorption of the product with the reactant weight ratio. The optimum IR ratio is determined from both and the weight ratio of the reactant is measured before heating in such a manner than the yield is maximized.
