Publication number: 20100225431Abstract: Provided are a steel having a non-magnetic portion, which can be applied to the steel of the remaining portion irrespective of the material and which has a structure of a short treating time required and a determined depth direction, its manufacturing method, and a revolving electric core. There is prepared an electromagnetic steel sheet having a recessed groove. A two-layered chip of a modifier metal foil and a stainless steel foil is so set in the groove of the electromagnetic steel sheet that the electromagnetic steel sheet and the stainless steel foil have surfaces of the same height. The modifier metal foil is melted when electric current is applied under pressure. When this pressing and current applying is continued, inner sides of the electromagnetic steel sheet and the stainless steel foil contacting the modifier metal foil are melted to form a nonmagnetic alloy layer in the region excepting the surface portions of an electromagnetic steel sheet layer and a stainless steel layer.Type: ApplicationFiled: August 27, 2008Publication date: September 9, 2010Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Keisuke Kadota, Hideo Aihara, Masahiko Mitsubayashi

Patent number: 6749959Abstract: The gas separator is provided with a substrate portion having a predetermined concave-convex shape, an underlying coating layer formed on the substrate portion, a first coating layer for coating the substrate portion and the underlying coating layer, and a second coating layer formed thereon. The second coating layer is formed from a carbon material, and is sufficiently conductive. Moreover, the second coating layer protects the underlying layer. The first coating layer is formed from a noble metal. Therefore, the first coating layer coated with the second coating layer exhibits extremely high corrosion resistance. The underlying coating layer and the substrate portion are coated with the first and second coating layers, so that the progress in corrosion can be sufficiently prevented. Thus, excellent overall corrosion resistance of the separator can be realized.Type: GrantFiled: March 12, 2001Date of Patent: June 15, 2004Assignee: Toyota Jidosha Kabushiki KaishaInventors: Hiromichi Nakata, Masayoshi Yokoi, Masazumi Onishi, Hideo Aihara, Masashi Murate, Yoshifumi Kaji
