Publication number: 20200395133Abstract: A nuclear fusion system includes: a muon generation unit for generating negative muons; a gas supply unit for circulating and supplying gaseous deuterium or gaseous deuterium-tritium mixture as raw material gas for a nuclear fusion reaction; and a Laval nozzle for accelerating the raw material gas to supersonic velocity including a flow regulation portion in which the muons are decelerated and a reaction portion in which the nuclear fusion reaction occurs, wherein an oblique shockwave, which is generated as a result of collision of a shock wave generator arranged inside the reaction portion and the raw material gas accelerated to supersonic velocity, converges on a center axis of the Laval nozzle, and thereby a high-density gas target is retained in a gas phase, and wherein the muons are introduced into the high-density gas target, and thereby the nuclear fusion reaction is caused to occur.Type: ApplicationFiled: August 25, 2020Publication date: December 17, 2020Applicant: CHUBU UNIVERSITY EDUCATIONAL FOUNDATIONInventors: Motoyasu SATO, Atsuo IIYOSHI, Yasushi KINO, Takashi MUTOH, Yoshiharu TANAHASHI, Norimasa YAMAMOTO, Hirohisa TAKANO, Yukihiko HASEGAWA

Patent number: 9109497Abstract: A vehicle cooling device includes a pump, circulation paths connected to the pump for circulating coolant between a cooling object and a heat exchanger, a solenoid valve for opening and closing at least one of the circulation paths, and a control unit for controlling pump operation. The solenoid valve includes a valve body movable between a position separated from a valve seat and a position abutting the valve seat, the valve body being held in abutment with the valve seat, and a solenoid maintaining the abutment when energized. The valve body allows coolant fluid pressure to move the valve body separate from the valve seat when the solenoid is not energized and the pump is in operation, and the control unit performs controlling to stop the pump and start solenoid energization when conditions are ready for stopping coolant circulation through the circulation path in which the solenoid valve is disposed.Type: GrantFiled: January 12, 2012Date of Patent: August 18, 2015Assignee: AISIN SEIKI KABUSHIKI KAISHAInventors: Masanobu Matsusaka, Tadayoshi Sato, Hirohisa Takano

Patent number: 8967095Abstract: An engine cooling apparatus includes an engine for vehicle traveling, a pump driven by the engine, a heat exchanger, a circulation passage for circulating cooling liquid between the engine and the heat exchanger by driving the pump, a solenoid valve capable of opening/closing the circulation passage, and a controller for controlling operations of the engine. The solenoid valve includes a valve body movable between a position away from a valve seat and a position contacting the valve seat and held to contact the valve seat and a solenoid capable of maintaining contact between the valve body and the valve seat in response to supply of power thereto. When driving of the pump under a non-energized state of the solenoid, the valve body is movable to the position away from the valve seat by the cooling liquid fluid pressure.Type: GrantFiled: January 12, 2012Date of Patent: March 3, 2015Assignee: Aisin Seiki Kabushiki KaishaInventors: Masanobu Matsusaka, Tadayoshi Sato, Hirohisa Takano

Patent number: 7311547Abstract: A cable connector having a receptacle connector, the receptacle connector includes a receptacle body which is made of an insulating material and into which a cable is inserted; a plurality of contacts which are provided in the receptacle body; a spacing member which separates the cable inserted into the receptacle body from the contacts by an elastic force of the spacing member to thereby provide an electrically disconnected state; and a biasing member which biases the cable toward the contacts against an elastic force of the spacing member. A movement restricting portion which restricts the movement of the cable toward the contacts so that the cable is brought into conductive contact with the contacts by the biasing force of the biasing member only when the cable is inserted to the predetermined position in the receptacle body.Type: GrantFiled: August 1, 2006Date of Patent: December 25, 2007Assignee: Kyocera Elco CorporationInventors: Hirohisa Takano, Tomoyuki Satoh

Patent number: 7264484Abstract: A connector includes a plug connector including a plug body, and at least one plug contact held by the plug body; and a receptacle connector including a receptacle body having a plug-in slot, and at least one receptacle contact held by the receptacle body so as to make contact with the plug contact for electric connection when the plug connector is plugged into the plug-in slot. The plug-in slot is formed between an island portion formed on the center of the receptacle body, and opposing wall portions of the receptacle body formed so as to oppose lateral surfaces of the island portion. Four corners at the top of the island portion are formed as slopes which approach the wall portions and extend downward from the top of the island portion, and are connected to the lateral surfaces which extend vertically.Type: GrantFiled: May 30, 2006Date of Patent: September 4, 2007Assignee: Kyocera Elco CorporationInventor: Hirohisa Takano
