Patent number: 8110120Abstract: A method of manufacturing a liquid crystal display apparatus includes forming at least one assembly for forming a plurality of finished liquid crystal display apparatuses, by opposing two glass substrates to have a space therebetween and sealing a periphery of the space between the two glass substrates by an outer peripheral seal member. Outer surfaces of the two glass substrates are etched by soaking the assembly in an etching solution within an etching bath while maintaining a temperature and a concentration of the etching solution within the etching bath at a substantially constant temperature and at a substantially constant concentration. The etched outer surfaces of the glass substrates are flattened by polishing the outer surfaces of the glass substrates.Type: GrantFiled: July 26, 2007Date of Patent: February 7, 2012Assignee: Casio Computer Co., Ltd.Inventors: Toshiharu Nishino, Yasushi Chiba, Masami Hara

Patent number: 5746534Abstract: A clip for windshield wiper blade has its shape designed for less occurrence of wobble relative to an arm piece. A penetration hole of the clip is formed in a taper configuration; smallest at a middle portion and largest at both open end portions. A thinned portion is formed around the middle portion by forming a recessed portion at a radially outer periphery of the middle portion. Supporting bars are disposed between a pair of side plates at a position opposite to the connecting bar.Type: GrantFiled: December 4, 1996Date of Patent: May 5, 1998Assignee: ASMO Co., Ltd.Inventor: Masami Hara

Patent number: 5396681Abstract: A wiper apparatus is disclosed in which a wiper linkage includes a pivot lever connected to a pivot shaft of a wiper arm for wiping a windshield glass of a vehicle, a pivot holder for supporting a pivot shaft, a link rod rotatably connected to the pivot lever, and a crank arm rotatably connected to the link rod. A wiper motor rotates the crank arm and moves the link rod reciprocatively. An elongated supporting pipe is fixed to the vehicle and supports the wiper linkage. A holding member holds the wiper motor to the supporting pipe. The holding member includes a mounting member to which the wiper motor is mounted and a fixing member for fixing the mounting member to the supporting pipe. The fixing member has a plurality of protruding portions which are elongated in a longitudinal direction of the supporting pipe on the inner periphery of the fixing member facing the supporting pipe. Also, each of the plurality of protruding portions provides a weld portion between the fixing member and the supporting pipe.Type: GrantFiled: September 14, 1993Date of Patent: March 14, 1995Assignee: Asmo Co., Ltd.Inventor: Masami Hara

Patent number: 5244734Abstract: A process for producing fine cellulose particles, which comprises(1) mixing viscose with a water-soluble anionic polymeric compound or polyethylene glycol or its derivative to form a dispersion of fine particles of viscose,(2) (i) heating the dispersion or mixing it with a coagulating agent to thereby coagulate the viscose in the dispersion, and thereafter neutralizing it with an acid to form fine particles of cellulose, or (ii) coagulating and neutralizing the dispersion with an acid to form fine particles of cellulose, and(3) thereafter, separating the fine particles of cellulose from the mother liquor. The fine cellulose particles(a) are composed substantially of II-type cellulose,(b) have a crystallinity, of 5 to 35% by weight,(c) are composed substantially of particles of not more than 20 micrometers, and(d) have a sharp particle size distribution.Type: GrantFiled: January 15, 1988Date of Patent: September 14, 1993Assignees: Kanebo Ltd., Kanebo Rayon, Ltd.Inventors: Shigeru Okuma, Kanji Yamagishi, Masami Hara, Keizo Suzuki, Toshihiro Yamamoto

Patent number: 5196527Abstract: This invention relates to ion-exchanged fine cellulose particles, porous fine cellulose particles which can be advantageously used as an affinity carrier, and methods of production thereof. These fine particles of the invention have the advantage that they possess excellent pressure-resistant strength and can treat treatment liquors under pressure at a high flowing velocity. Thus, they can be advantageously used industrially in various separation and purification processes.Type: GrantFiled: February 4, 1992Date of Patent: March 23, 1993Assignee: Kanebo Ltd.Inventors: Shigeru Ookuma, Kouei Igarashi, Masami Hara, Kazuhiro Aso, Hideo Yoshidome, Hiroshi Nakayama, Keizo Suzuki, Kazuhiko Nakajima
