Patent number: 9897380Abstract: A carrier transport system transports a plurality of carriers by a transport conveyor into a heating furnace, advances a comb-shaped carrier stopper having a plurality of protrusions toward the carriers, moves the carriers by the transport conveyor in a transport direction to engage cutout grooves, provided respectively for the carriers, with the protrusions of the carrier stopper to thereby position the carriers at a time. The carrier transport system advances the carrier stopper toward the carriers to insert distal ends of the protrusions of the carrier stopper into insertion holes, and then determines, on the basis of a moved distance X of the carrier stopper, whether the carriers are properly positioned.Type: GrantFiled: September 4, 2013Date of Patent: February 20, 2018Assignees: TOYOTA JIDOSHA KABUSHIKI KAISHA, HIRATA CORPORATIONInventors: Masanari Matsuura, Sotaro Oi, Tomoyuki Kubota

Patent number: 9033705Abstract: A hydrogen vacuum furnace (100) is provided with a process chamber (1) wherein a subject (10) to be heated is stored; a heating chamber (2) wherein a heater lamp (25) is stored; and a crystal board (3) for separating the subject (10) and the heater lamp (25) one from the other. In the hydrogen vacuum furnace (100), the subject (10) is heated by a radiant ray applied from the heater lamp (25). The process chamber (1) and the heating chamber (2) are provided with gas feed ports (11, 21) and exhaust ports (12, 22), respectively, for feeding and exhausting a gas. When the subject (10) is being heated, atmospheric pressure in each chamber is adjusted so that the heating chamber (2) is under positive pressure to the process chamber (1) by feeding or exhausting the gas.Type: GrantFiled: August 6, 2008Date of Patent: May 19, 2015Assignees: TOYOTA JIDOSHA KABUSHIKI KAISHA, HIRATA CORPORATIONInventors: Masanari Matsuura, Sotaro Oi, Tomoyuki Kubota, Masaya Tsuruta

Patent number: 8297429Abstract: A conveyance section positioning method has carrier pallets on which workpieces are fixed, a conveyer, a heating furnace for heating the workpieces, and a positioning mechanism for positioning the carrier pallets, and the method stops the carrier pallets at predetermined positions. The heating furnace has halogen heaters for heating the workpieces. The carrier pallets each have projections and output grooves. Comb tooth-shaped stopper projections engaging with the projections are formed on a carrier stopper. When the carrier stopper is moved forward, the stopper projections and the projections are engaged with each other. In this one operation, the carrier pallets are positioned at places corresponding to the halogen heaters, and then the workpieces are heated.Type: GrantFiled: November 5, 2008Date of Patent: October 30, 2012Assignees: Toyota Jidosha Kabushiki Kaisha, Hirata CorporationInventors: Masanari Matsuura, Sotaro Ol, Tomoyuki Kubota, Masaya Tsuruta

Patent number: 8271124Abstract: An object is heated to a preheating temperature in an atmosphere of a reducing gas under the atmospheric pressure while adjusting the setting of the emissivity of a non-contact temperature measuring part and regulating the temperature of the object according to the measured value measured by a contact temperature measuring part. The pressure of the atmosphere is reduced. The object is further heated to a heating temperature under a lowered pressure while regulating the temperature of the object according to the measured value measured by the non-contact temperature measuring part whose setting of the emissivity is adjusted during the heating process to the preheating temperature. The pressure of the atmosphere is increased back to the atmospheric pressure while maintaining the heating temperature of the object. The temperature of the object is decreased under the atmospheric pressure.Type: GrantFiled: December 8, 2008Date of Patent: September 18, 2012Assignees: Toyota Jidosha Kabushiki Kaisha, Hirata CorporationInventors: Sotaro Ol, Masanari Matsuura, Tomoyuki Kubota, Masaya Tsuruta

Patent number: 7649159Abstract: The present invention provides technology that uniformly heats and melts a plurality of solder material arranged in a plurality of locations on a board, and uniformly solders a plurality of parts to the board that are arranged in a plurality of locations on the board. A soldering apparatus includes an induction coil having a length in the longitudinal direction that is longer than the length of the board. An inner space having a size sufficient to arrange the board therein is maintained inside the induction coil. The board supporting the parts and the solder material will be positioned in the approximate center of the inner space of the induction coil. An alternating current will flow through the induction coil in this state. An alternating magnetic field will be generated in the inner space of the induction coil. Magnetic fluxes will substantially uniformly pass through the inner space of the induction coil along the longitudinal direction of the induction coil.Type: GrantFiled: July 14, 2006Date of Patent: January 19, 2010Assignees: Toyota Jidosha Kabushiki Kaisha, Hirata Corporation, Nihon Den-Netsu Keiki Co., Ltd.Inventors: Masanari Matsuura, Masahiro Koizumi, Masaya Tsuruta, Tomoyuki Kubota, Yoshiyuki Nakamura
