Patent number: 9350219Abstract: A purpose is to provide a rotor manufacturing method including a magnet assembly formed of divided permanent magnet pieces to enhance insulation and advance cost reduction. The rotor manufacturing method includes forming permanent magnet pieces by dividing a permanent magnet, arranging and resin-molding the permanent magnet pieces to form a magnet assembly, and placing the magnet assembly in a rotor. The method includes placing the permanent magnet pieces all together in a molding die for use in resin-molding, and moving the permanent magnet pieces by a moving device provided in the molding die to move the permanent magnet pieces within the molding die, thereby forming the magnet assembly.Type: GrantFiled: February 14, 2011Date of Patent: May 24, 2016Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Tetsuyoshi Fukaya, Yasushi Nishikuma

Publication number: 20160037690Abstract: An electromagnetic shield body includes a metal plate and insulating resin combined with each other by insert molding. The metal plate is provided with a projection portion projecting into the insulating resin from the metal plate. The projection portion has a supporting side that dams up and holds the insulating resin introduced into a space defined by the projection portion.Type: ApplicationFiled: July 15, 2015Publication date: February 4, 2016Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Fumio NOMIZO, Hideo SATAKE, Tetsuyoshi FUKAYA, Hirofumi INOSHITA

Publication number: 20140109392Abstract: In a method for manufacturing a rotor in which a plurality of cleaved magnet pieces are mounted in a rotor core with cleaved surfaces of the cleaved magnet pieces in an engaged state. In a cleaving step, a magnet workpiece having a recess in a surface thereof is cleaved at the recess as a starting point, thereby producing a first magnet piece and a second magnet piece. In a surface processing step, the cleaved surface is processed to reduce protrusions on the cleaved surface of the first magnet piece. Accordingly, the engagement between the cleaved surfaces is poor, the contact area is reduced, and the contact resistance is increased. As a result thereof, the eddy currents in the cut magnets flow less easily, and loss caused by eddy currents may be decreased.Type: ApplicationFiled: May 19, 2011Publication date: April 24, 2014Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Yasushi Nishikuma, Tetsuyoshi Fukaya, Katsuhiko Tatebe, Shingo Fubuki

Publication number: 20130153176Abstract: A method of manufacturing a flat type heat pipe, having an inside of which partitioned into a plurality of cells, that is capable of flexibly setting a concentration of working fluid in each cell is provided. The method includes processes of preparing a flat container, pouring, and closing. In the preparing, the flat container having the inside of which two-dimensionally partitioned into the plurality of cells is prepared. The flat container has connecting holes through which adjacent cells communicate and an inlet hole for the working fluid to be poured from outside. In the pouring, the working fluid is poured into respective cells through the inlet hole and the connecting holes. In the closing, the inlet hole and the connecting holes are closed. In one method, after sealing a specified cell, following processes of heating, removing air, pouring, evaporating, and closing are repeated for other cells.Type: ApplicationFiled: August 8, 2011Publication date: June 20, 2013Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Takahito Mizuno, Yuya Takano, Tetsuyoshi Fukaya, Eisaku Kakiuchi
