Patent number: 11273513Abstract: A coupling device couples, using a coupling member, a first plate of a first metal to a second plate of a second metal. A power source is connected to first and second electrodes. A driver moves the first and second electrodes relative to the coupling member and the first and second plates. A controller controls the power source and the driver to electrify the coupling member and the first and second plates under pressure. The coupling member includes a third metal approximately identical to the second metal. The first metal has a melting point lower than melting points of the second and third metals. The coupling member includes a pilot portion that is located about a center of a flat surface of a body of the coupling member and that protrudes in an extending direction. The flat surface has discharge grooves radially extending from the pilot portion.Type: GrantFiled: February 27, 2019Date of Patent: March 15, 2022Assignee: SHINKO HOLDINGS CO., LTD.Inventors: Rikiya Nishimura, Etsuo Masunaga

Patent number: 11267070Abstract: A coupling device is configured to, using a coupling member, couple a first plate made of a first metal and a second plate made of a second metal to each other, and includes a first electrode, a second electrode, a power source, a driver, and a controller. The power source is connected to the first electrode and the second electrode. The driver is configured to move the first electrode and the second electrode relative to the coupling member, the first plate, and the second plate. The controller is configured to control the power source and the driver to electrify the coupling member, the first plate, and the second plate while controlling the first electrode and the second electrode to apply pressure to the coupling member, the first plate, and the second plate.Type: GrantFiled: February 27, 2019Date of Patent: March 8, 2022Assignee: SHINJO HOLDINGS CO., LTD.Inventors: Rikiya Nishimura, Etsuo Masunaga

Patent number: 8052417Abstract: A first and second inner dies are combined to form a molding cavity, in which a fluidic material is charged and hardened for molding a tubular member, which has a side surface at least partially defining a projected portion being higher at one end than the other end. The first inner die forms an inner space of the tubular member. The second inner die forms the projected portion. A first actuating unit draws the first inner die from the other end along a first moving path, which is substantially linear along an axis of the tubular member. A second actuating unit draws the second inner die from the other end along a second moving path, which bulges toward the inner space and passes through the inner space.Type: GrantFiled: January 8, 2009Date of Patent: November 8, 2011Assignee: Denso CorporationInventors: Rikiya Nishimura, Masaei Mitomi, Hiroyuki Sato
