Patent number: 7249940Abstract: A temperature regulator main body is connected to a cooling hole formed in a temperature regulating part under a hopper through a tube and comprises a tank for a cooling medium, a pump, a radiator, and a fan facing the radiator to send cold air and driven by a motor. By driving of the pump, the cooling medium circulates between the temperature regulating part under the hopper and the temperature regulator main body. A temperature sensor is provided to the temperature regulating part under the hopper. A controller for controlling an injection molding machine cools the circulating cooling medium by the fan and feedback controls the temperature of the temperature regulating part under the hopper when a temperature detected by the temperature sensor is higher than a preset temperature.Type: GrantFiled: June 3, 2004Date of Patent: July 31, 2007Assignee: FANUC LtdInventors: Koji Senda, Hideki Koyama

Patent number: 6593432Abstract: A sulfur vulcanizing system rubber composition comprises EPDM, zinc as a vulcanization accelerator activator, at least one thiazole type vulcanization accelerator serving to control the dissolution of zinc from the composition, and at least one ultra-accelerator of the thiuram or dithiocarbamate type, these accelerators being preferably combined under specified quantitative limitations. The hose using this rubber composition is particularly suitable for use in a cooling system for an automobile engine, since the dissolution of zinc into a coolant is prevented, thereby preventing the formation of any zinc compound causing the blocking of the hose, or the leakage of the coolant through the seal between the hose and any pipe connected therewith.Type: GrantFiled: July 27, 2000Date of Patent: July 15, 2003Assignee: Tokai Rubber Industries, Ltd.Inventors: Ayumu Ikemoto, Eiichi Daikai, Koji Senda

Patent number: 6552128Abstract: A rubber composition which can achieve superior adhesion force between it and a material to be adhered without a coating of an adhesive. The rubber composition includes the following components (A) to (D): (A) a rubber composed of at least one of an ethylene-propylene-diene terpolymer and an ethylene-propylene copolymer, (B) a peroxide vulcanizing agent, (C) a resorcinol-based compound, and (D) a melamine resin.Type: GrantFiled: October 2, 2001Date of Patent: April 22, 2003Assignee: Tokai Rubber Industries, Ltd.Inventors: Ayumu Ikemoto, Koji Senda

Patent number: 6543785Abstract: A packing structure has a core element of a material having a high fluid impermeability, and a thin coated rubber layer formed thereon to cover at least its sealing surface and having a glass transition temperature which is lower than the lowest temperature allowable for the packing structure. It shows a high sealing property even at a low temperature and a high fluid impermeability when used for sealing e.g. a pipeline for conveying fuel in a motor vehicle.Type: GrantFiled: November 28, 2000Date of Patent: April 8, 2003Assignee: Tokai Rubber Industries, Ltd.Inventors: Kazutaka Katayama, Hidehito Ikeda, Tetsuji Narasaki, Koji Senda

Patent number: 6534578Abstract: A refrigerant hose for an air conditioner has an inner wall layer formed of a laminate of an inner resin layer and an outer rubber layer bonded by its vulcanization to the resin layer. The rubber layer is of a composition comprising butyl rubber, an adhesive material based on resorcinol and a vulcanizing agent based on an alkylphenol-formaldehyde resin, and having a bromine content of at least 0.5% by weight. The hose having the inner wall layer surrounded by a reinforcing layer and an outer wall layer exhibits a high adhesive strength even at an elevated temperature between its refrigerant-impermeable resin layer and its water-impermeable rubber layer.Type: GrantFiled: July 27, 2000Date of Patent: March 18, 2003Assignee: Tokai Rubber Industries, Ltd.Inventors: Eiichi Daikai, Koji Senda

Patent number: 5772932Abstract: A mold clamping control method capable of preventing any warp or strain on a molded product without stopping an injection pressure holding process so as to cancel the pressing force of an injection screw. In a series of injection and pressure holding processes, a movable platen is retracted from a mold clamping dwell position P2 to a mold opening dwell position P1, so that a substantial volume of a cavity of a mold is increased to temporarily lower the internal pressure of the cavity, thus making an internal stress of resin to be a product uniform to eliminate stress strains. In this method, an injection molding is performed to produce a precise product having no warp or strain even in molding a light guide plate which is subjected to molding abnormalities by the temporary stoppage of the injection pressure holding process according to the conventional method.Type: GrantFiled: July 29, 1996Date of Patent: June 30, 1998Assignee: Fanuc Ltd.Inventors: Masao Kamiguchi, Yuichi Hosoya, Koji Senda, Noriaki Neko
