Title: Recovery of polymer
Inventor: YAMANASHI TERUAKI
IPC: C08F220/04
Filed: 1977-09-27
Abstract: PURPOSE: To recover a high-purity conjugated diene-maleic anhydride copolymer in high yield and high elimination ratios of (substituted) tetrahydrophthalic anhydride and the residue of polymerization catalyst, by the liquid-liquid-separation in the presence of a specific recovery solvent.  
     CONSTITUTION: (1) A conjugated diene, e.g. butadiene, etc., is copolymerized with maleic anhydride in a polymerization solvent, e.g. acetone, etc., in the presence of a catalyst, e.g. radical initiator, etc., to give a reaction solution. (2) A recovery solvent (e.g. n-butane, etc.) in which the copolymer is insoluble at room temperature to 100°C, (preferably 0.1W1 parts by weight on the basis of 1 part by weight of the polymerization solvent) is mixed with the above solution. (3) The mixture is stirred preferably at 10W150°C for 30 min to 20 hr, thereafter separated into two liquid layers. (4) The copolymer is recovered by separating the liquid layer containing it and removing the solvent, or by precipitating it by adding the liquid layer to a poor solvent

Title: Liquid crystal display device, its production and apparatus for production therefor
Inventor: IWAKOSHI YOKO
IPC: G02F1/1337
Filed: 1994-05-27
Abstract: PURPOSE:To obtain a wide visual field angle characteristic without increasing and complicating production stages and without contamination and chipping of oriented films. CONSTITUTION:The oriented films 14 formed on the inside surfaces of a pair of substrate parts 15 are irradiated with polarized light 18 via a polarizing filter 16, by which liquid crystals are oriented in an arbitrarily polarization direction. As a result, the increase in the production stages is averted and since the orientation treatment is executed without contact with the oriented films 14, the orientation treatment which does not contaminate and chip the oriented films 14 is made possible; in addition, the liquid crystal display device having the wide visual field angle characteristic is obtd. Further, the liquid crystal molecules have arbitrarily pretilt angles if the oriented films are irradiated with the polarized light 18 from a diagonal direction.

Inventor: HOSHINO SHUICHI
IPC: G07D7/02
Filed: 1991-04-19
Abstract: PURPOSE:To prevent an information storing card from being forged by using a hologram having a reflecting direction characteristic for reflecting illumination light to plural directions at prescribed rates as a reflecting face part. CONSTITUTION:A card 1 inserted into a card reader/writer is carried, illumination light is projected from a light emitting element 5 to a hologram part 4 and its reflected light is received by a light receiving element 6. Output voltages, i.e., the distribution of light receiving intensity, outputted from respective parts of the element 6 are compared with the distribution of output voltages outputted from respective parts at the time of irradiating the hologram part 4 of a normal card 1 stored in a storage part with illumination light, and when both the distribution states coincide with each other, an identification unit 7 identifies the card 1 as a normal card. Consequently information storing cards such as a magnetic card and an optical card can be prevented from being forged.

Title: Fan-out circuit
Inventor: WATANABE NOBORU
IPC: G11C8/00
Filed: 1978-09-22
Abstract: PURPOSE:To quicken access to a memory by simplifying a fan-out circuit which uses a fan-out gate with positive and negative polarity outputs, by using inversion output of address information. CONSTITUTION:Address information supplied through address line 4 is branched into three outputs of positive and negative polarities by fan-out gates 21-23, whose outputs are inputted to memory circuit group 3 through output lines 51-53 respectively. As a result, the fan-out output of the same address line 4 is inverted in polarity between memory chips 301 and 304, for example, and consequently memory positions of chips 301 and 304 can be made different bearing fixed relation. In this way, the circuit can be simplified by using an inversion output without using fan-out gates to several stages and memory access operation can be quickened.

Filed: 1997-04-18
Abstract: PROBLEM TO BE SOLVED: To surely stop the speed change motor of a bicycle at the target stop position in spite of the aging change of dry batteries. SOLUTION: A set value setting the speed change of a speed change motor is inputted to a control device, it is digitally processed inside, and the speed change instruction signal instructing the speed change of the speed change motor is outputted from the control device.
