Patent number: 9929612Abstract: A new rotor for a rotating electric machine assuring outstanding durability and reliability against vibration and facilitating equalization of resistances among a plurality of rotor coils, while allowing the leading ends of a plurality of lead wires to be disposed so as to congregate in one area, is provided. A plurality of stator coils 102 wound at a cylindrical stator core 101 each include leader portions led out from one of two ends of a slot along the axial direction and extending astride a plurality of slots. Lead wires 300 each formed at one end of a stator coil 102 are disposed so that their leading ends, oriented in the same direction, congregate in a single area. In a leader portion where a lead wire 300 is located, a turnback portion 400, made to turn back with an angle equal to or greater than 90° from an inclining wire portion 113, which is led out with an inclination along a predetermined direction from the slot, is formed.Type: GrantFiled: October 7, 2013Date of Patent: March 27, 2018Assignee: Hitachi Automotive Systems, Ltd.Inventors: Tomohiro Fukuda, Takahiro Ohmori, Takashi Genmoto, Kenichi Nakayama, Hisaya Shimizu

Publication number: 20150030814Abstract: A vehicle interior member includes a main body member having multiple recessed portions and raised portions and being made of a synthetic resin, a first plate-shaped member thermally welded on a front surface of the main body member, and a second plate-shaped member thermally welded on a back surface of the main body member. Each of the first plate-shaped member and the second plate-shaped member is a foamed sheet obtained by foaming a synthetic resin by adding a blowing agent to the synthetic resin.Type: ApplicationFiled: July 1, 2014Publication date: January 29, 2015Inventors: Takahiro OHMORI, Ryo YAMAGUCHI

Publication number: 20150015110Abstract: An electric rotating machine is provided that can ensure insulation quality between a coil end and an inside wall of a housing or of a case. The electric rotating machine includes a stator including a stator core and a stator winding. The stator core has a plurality of slots rowed in a circumferential direction. The stator winding is formed of a conductor rectangular in a cross section and is inserted into the slots, the conductor being provided with an insulating coated layer. The stator winding has a first segment transition bent section provided on a radially outside of the stator and a second segment transition bent section provided on a radially inside of the stator. The first segment transition bent section has a layer-transition bent section angle greater than a layer-transition bent section angle of the second segment transition bent section.Type: ApplicationFiled: January 15, 2013Publication date: January 15, 2015Inventors: Tomoaki Kaimori, Yoshimi Mori, Takahiro Ohmori, Kenichi Nakayama

Patent number: 8760019Abstract: A rotating electric machine includes a rotor and a stator. The stator coil of the stator includes a set of a first stator coil and a second stator coil that is stored in an adjacent slot to a slot in which the first stator coil is stored, with a number of the set being same as a number of phases, and one end of each of the first stator coil and the second stator coil is a lead section and an other end is a neutral point. A plurality of the stator coils are arranged radially in layers in each slot, and a lead section of the first stator coil and a lead section of the second stator coil are connected with each other with one of the lead sections extending from an outermost layer of the slot and an other of the lead sections extending from an innermost layer of the slot so that the connected lead sections constitute an external connection terminal.Type: GrantFiled: June 29, 2010Date of Patent: June 24, 2014Assignee: Hitachi Automotive Systems, Ltd.Inventors: Yoshimi Mori, Toshiaki Ueda, Takahiro Ohmori, Kohei Ichikawa, Kenichi Nakayama

Patent number: 5513056Abstract: A magnetic head slider (1) has a first rail (20) with a first air bearing surface, a second rail (25) with a second air bearing surface and further a third rail (15) with a third air bearing surface. The third rail is formed between the first rail (20) and the second rail (25). On both sides of the third air bearing surface (16), a first air pressurization part (17) and a second air pressurization part (18) are formed sunk by respective depths. When the skew angle ".theta." occurs, appropriate pressurized air flows are generated by the first air pressurization part (17) and the second air pressurization part (18) to compensate for the lifting force.Type: GrantFiled: March 15, 1994Date of Patent: April 30, 1996Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Mikio Kawasaki, Takahiro Ohmori, Hiroshi Tomiyasu
