Publication number: 20240074030Abstract: An electronic apparatus includes a first board having a heat generating element, a second board, a support member having a fixing part to which the second board is fixed, and which supports the second board so as to overlap with the first board separated by a distance, and a heat dissipation member on an opposite side of the first board across the second board and the support member, so as to overlap with the second board separated by a distance. The support member includes a heat receiving part thermally connected to the heat generating element, a first heat transfer part which transfers heat received by the heat receiving part to the heat dissipation member, and a second heat transfer part which transfers heat received by the fixing part to the heat dissipation member. The support member has a shape which reduces heat transfer from the heat receiving part to the fixing part.Type: ApplicationFiled: November 3, 2023Publication date: February 29, 2024Inventors: Honkai TOMIMOTO, Hideki KAWASHIMA

Patent number: 11003047Abstract: A lens barrel that is capable of miniaturizing and thinning an image pickup apparatus by enabling to switch manual lens drive and electric lens drive with a simple mechanism. A lens barrel is mounted on an image pickup apparatus that supports an operation member rotatably. A drive barrel engages with a lens holding member to drive it in an optical axis direction. A motor transfers rotation to the drive barrel through a transfer mechanism. A switching mechanism switches between electric lens drive that drives the lens holding member by transferring rotation of the motor to the drive barrel and manual lens drive that drives the lens holding member by transferring rotation of the operation member to the drive barrel via an elastic member that rotates together with the operation member according to a user's operation. The drive barrel engages with the elastic member while shifting to a photographing area.Type: GrantFiled: July 6, 2018Date of Patent: May 11, 2021Assignee: CANON KABUSHIKI KAISHAInventors: Yosuke Fukai, Hideki Kawashima, Kenichi Katano

Patent number: 10000205Abstract: A fail-safe control device is provided for hybrid vehicles which allows a travel distance of a vehicle to be extended in an event of an ON-failure of a second clutch. An integrated controller switches between an HEV mode and an EV mode by controlling a first clutch between an engine and a motor, and a second clutch between the motor and a continuously variable transmission. The integrated controller prohibits the transition from the HEV mode to the EV mode when a clutch failure determination unit detects an ON-failure of the second clutch while the vehicle is traveling in the HEV mode.Type: GrantFiled: March 20, 2015Date of Patent: June 19, 2018Assignee: Nissan Motor Co., Ltd.Inventors: Kenji Koshiba, Takeo Aizawa, Hideki Kawashima

Patent number: 9376167Abstract: A inject gas control device that performs, for example, control reflecting variation in vessel velocity over time without adversely affecting the main engine is realized. That is, it is prevented that gas is drawn too much and thereby a gas supply or charged air rate becomes insufficient, efficiency of the main engine is decreased and exhaust gas is deteriorated, and analogous events occur because the gas supply or charged air rate is too much instead. There are provided a main engine 4010 acquiring propelling power for a vessel 1, and a turbocharger 4011 that is driven by exhaust gas from the main engine 4010 and blows pressurized gas to the main engine 4010. A part of the pressurized gas and/or exhaust gas is drawn from between the turbocharger 4011 and the main engine 4010 (5023, 5024 and 5025).Type: GrantFiled: March 31, 2009Date of Patent: June 28, 2016Assignee: NATIONAL MARITIME RESEARCH INSTITUTEInventors: Hideki Kawashima, Tetsugo Fukuda, Yoshiaki Kodama, Munehiko Hinatsu, Toshifumi Hori, Masahiko Makino, Kazuyoshi Harumi, Masashi Ohnawa, Haruya Takeshi, Tadanori Takimoto
