Patent number: 11285562Abstract: A friction stir welding apparatus and method maintains a depth of a welded part constant without varying a depth-direction position of a welding tool leading end part relative to welded members. A control device controls an operation of the friction stir welding apparatus, and a holder unit is connected to a swing mechanism unit via a revolving mechanism section, and a welding tool is held to the holder unit. The control device has a first welding mode in which friction stir welding is performed on the basis of a welding condition signal for deciding a welding condition of the welding tool, a swing control signal for controlling the swing mechanism unit, a first hold position decision signal, and a second welding mode in which friction stir welding is performed on the basis of the welding condition signal, the swing control signal, and a second hold position decision signal.Type: GrantFiled: March 27, 2019Date of Patent: March 29, 2022Assignees: HITACHI POWER SOLUTIONS CO., LTD., MAZDA MOTOR CORPORATIONInventors: Tomio Odakura, Hiroki Abe, Akihiro Satou, Kohei Funahara, Koichi Ishiguro, Shun Shinohara, Yukihiro Sugimoto, Katsuya Nishiguchi, Koujirou Tanaka, Yasuhiro Morita

Patent number: 10335895Abstract: A friction stir welding device includes: a control device which causes a pin part to be inserted into members to be joined while causing a joining tool to rotate and which causes a joining head to move along a joint line via a robot main body; and an image pickup device which detects a junction deviation that is a deviation between the joining head and a direction along the joint line. Also, when a junction deviation is generated, this control device causes the joining head to move in a direction toward the joint line and thus resolves the junction deviation.Type: GrantFiled: April 7, 2016Date of Patent: July 2, 2019Assignee: Hitachi Power Solutions Co., Ltd.Inventors: Tomio Odakura, Koichi Ishiguro, Kenji Ando

Patent number: 7442516Abstract: The present invention provides an antibody which specifically recognizes a CNS tau protein but not a peripheral tau protein. More specifically, the present invention provides an antibody obtainable by using a polypeptide comprising an amino acid sequence of a connective portion between the amino acid sequence encoded by Exon 4 of a gene encoding a tau protein and the amino acid sequence encoded by Exon 5 thereof as an epitope specific to the isoform of tau protein predominantly existing in central nervous tissues. The present invention further provides a method of detecting Alzheimer's disease and a reagent kit using the antibody.Type: GrantFiled: February 11, 2005Date of Patent: October 28, 2008Assignees: Mitsubishi Chemical Corporation, Mitsubishi Kagaku Iatron, Inc.Inventors: Hideto Ohno, Koichi Ishiguro, Masaki Imagawa
