Patent number: 6705672Abstract: An air-conditioning duct structure is included in a vehicular dash beam member. Material for the duct is made of a heat insulating and sound absorbing material and is adhered onto the surface of a sheet material for the beam member which is then bent into a semi-tubular shape so that the material for the duct is positioned inside thereby forming beam member bodies. Beam member bodies are combined by joining their joining surfaces that face each other to thereby form a tubular closed sectional shape. Achieving vibration attenuation, noise absorption and the heat insulating functions with an inner surface sheet member of an air conditioning duct is achievable. An air conditioning duct extending across a vehicle's width is formed by joining a metal reinforcing member and a resin cover. The sheet member is put between the reinforcing member and the cover.Type: GrantFiled: April 9, 2002Date of Patent: March 16, 2004Assignee: Denso CorporationInventors: Kazushi Shikata, Tomohiro Kamiya, Koichi Ito, Takahiro Yoshida, Mikio Hirano, Satoshi Mizutani

Patent number: 6577587Abstract: A turntable device includes a disc base on the circumference thereof, and the disc base has a hardness more than a given level. The surface of the disc base is roughened at a given level in order to prevent the disc from slipping and adhesion to the disc base. The disc base can compensate surface wobble caused by the disc base. A manufacturing method of the turntable device includes the steps of: a) dripping liquid resin mixed with fine particles on the circumference of the turntable; and b) hardening the resin to form the disc base. The turntable device is good for e.g. CD players, optical disc driving apparatuses.Type: GrantFiled: November 16, 2000Date of Patent: June 10, 2003Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Taro Kishibe, Mikio Hirano, Shigenori Uda, Yuko Otani, Masashi Senoo, Kouji Kuyama, Shuichi Yamane, Akio Ando

Patent number: 5729072Abstract: In a stator for an electric motor, insulating members are formed on laminated iron cores divided for each pole-tooth unit in the direction of the output shaft and windings are applied perpendicularly to the pole-tooth portions in a high-density alignment. After a predetermined number of the laminated iron cores are combined so as to form a cylindrical configuration, they are welded at the outer end portions of the dividing surfaces in the direction of lamination so as to construct an integral structure stator with rigidity, thereby enabling high densification of the windings (conductor space factor of 70%) and space-savings in the winding end portions. Further, as any joint portions between the pole-tooth portions are not necessary, reduction (5 to 10%) in motor efficiency due to such joint portions can be prevented, and, as any integrally forming by resinous members is not necessary, inter-winding short-circuiting is not caused. Welding may be replaced by adhesive bonding.Type: GrantFiled: September 20, 1993Date of Patent: March 17, 1998Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Mikio Hirano, Seiji Kikuchi, Manabu Takeuchi, Hiroshi Kawazoe, Kouzi Fukuda, Takashi Akiyama, Koichi Nakatsukasa, Hideki Yamanaka, Kazunori Morita

Patent number: 4904619Abstract: A method of producing a Josephson junction device consisting of thin films of superconducting materials such as niobium and niobium nitride that work at cryogenic temperatures, in which a base electrode layer, tunnel barrier layer and a counterelectrode layer constituting a Josephson junction are formed on a substrate. In order to form a desired electrode pattern on the counterelectrode layer, a resist pattern is used as a mask for dry etching, followed by a plasma ashing process for ablating part of the resist in order to form a terrace-shaped portion at the edges and corners of the counterelectrode pattern by reforming and shrinking the cross-sectional geometry of the resist. Then, a thin insulating film for covering the edged layers is deposited over the entire surface of substrate, followed by the removal of said resist pattern together with said insulating film deposited on said resist pattern in order to form a protecting layer around the counterelectrode pattern.Type: GrantFiled: February 1, 1988Date of Patent: February 27, 1990Assignee: Hitachi Ltd.Inventors: Hirozi Yamada, Sachiko Kizaki, Hiroyuki Mori, Yoshinobu Tarutani, Mikio Hirano

Patent number: 4299721Abstract: Provided is a method of producing radio-active waste package. By evaporating and drying, the radio-active waste is reduced to a radio-active powder which is formed into pellets in order to ease its disposal. The pellets are received in a container and then impregnated therein with a thermoplastic composition so as to be integrally solidify in the container. The prior technical method cannot fully impregnate the pellets with the thermoplastic material. The present invention improves the prior art technical method of producing radio-active waste package thereby to eliminate the above disadvantage. The present invention also provides a device for carrying out the above method.Type: GrantFiled: November 30, 1978Date of Patent: November 10, 1981Assignee: Hitachi, Ltd.Inventors: Mikio Hirano, Susumu Horiuchi

Patent number: 4290907Abstract: Granular ion exchange resins in a desalter provided in a nuclear power plant are taken out from the desalter as used ion exchange resins when their capacities are lowered. The used ion exchange resins in a slurry state are led to a thin film drier. A rotating shaft provided with rotating blades is inserted in the thin film drier. When the slurry of the used ion exchange resins is led thereto, the rotating shaft is driven to rotate, and the side wall of the thin film drier is heated. The used ion exchange resins led to the thin film drier are heated and pulverized to powder by the action of rotating blades. The powder is taken out of the thin film drier to the outside and shaped into pellets.Type: GrantFiled: November 22, 1978Date of Patent: September 22, 1981Assignee: Hitachi, Ltd.Inventors: Susumu Horiuchi, Mikio Hirano, Hideo Yusa, Koichi Chino, Tatsuo Hayashi
