Patent number: 9115589Abstract: An impeller integrally includes a substrate and multiple impeller blades provided upright along a curved shape and circumferentially spaced apart on one face of the substrate. The impeller blades expand in diameter and each include an inner circumferential-side blade portion on the inner circumferential side of the substrate and extending in the rotary shaft core direction and have a tip side that is bent, and an outer circumferential-side blade portion on the outer circumferential side of the substrate and extending in the rotary shaft core direction. In the direction along the rotary shaft core, the length of the inner circumferential-side blade portion from the substrate side to the tip side is longer than the length of the outer circumferential-side blade portion from the substrate side to the tip side, and the blade thickness of the inner circumferential-side blade portion gradually decreases from the substrate side toward the tip side.Type: GrantFiled: June 6, 2011Date of Patent: August 25, 2015Assignee: AISIN SEIKI KABUSHIKI KAISHAInventors: Motohisa Ishiguro, Tomoyasu Hirano

Patent number: 5395037Abstract: A method for bonding a solder wire is provided wherein a lower ball end of a material solder wire is first bonded to a first bonding portion of a workpiece. Then, the material solder wire is thermally cut to provide a solder wire segment held bonded to the first bonding portion and having an upper ball end. Finally, the upper ball end is bonded to a second bonding portion of the workpiece. All of the wire bonding process steps are performed in an oxygen-free atmosphere to prevent oxidation of the solder wire.Type: GrantFiled: December 20, 1993Date of Patent: March 7, 1995Assignee: Rohm Co., Ltd.Inventors: Hiroyuki Takahashi, Shinichi Fujino, Kazuhiro Sakamoto, Tomoyasu Hirano
