Patent number: 8765219Abstract: A method for producing a metal-resin composite includes a coating step, an assembling step, and a heating step. The coating step coats at least part of the outer periphery of a solid metal first member with a foaming resin and a non-foaming resin. The assembling step disposes the first member within a hollow metal second member. The heating step heats an assembly of the second member within which the first member coated with the foaming resin and the non-foaming resin with the axes of the first member and the second member extending in the horizontal direction, and thus foams the foaming resin between the first member and the second member.Type: GrantFiled: May 2, 2008Date of Patent: July 1, 2014Assignee: Kobe Steel, Ltd.Inventors: Hironobu Nakanishi, Akio Sugimoto

Patent number: 8500473Abstract: A projected end of a bus bar (20), including projection portions (21A, 22B, 23C, 24D, 25E, 26F), and a recessed connector (30), including a cylindrical portion (43A), a recess portion (31B), a cylindrical portion (42C), a recess portion (31D), a cylindrical portion (41E), and a recess portion (31F), are engaged with each other, thereby enabling the bus bar (20) and the connector (30) to electrically connect with each other. That is, only inserting the bus bar (20) into the connector (30) makes an electrical connection possible, so it is not necessary, for example, to fasten the terminal with a screw. Therefore, this facilitates the connection between the bus bar (20) and the connector (30).Type: GrantFiled: June 3, 2010Date of Patent: August 6, 2013Assignee: Kobe Steel, Ltd.Inventors: Nagoya Fujiwara, Akio Sugimoto, Hiroshi Hashimoto, Takayasu Fujiura, Naoki Kikuchi, Koji Inoue
