Patent number: 8960036Abstract: A gear coupling device and a gear coupling method reduce a vibration and noise caused at the time of engagement of gears. The gear coupling device transmits power through the engagement of the gears and uncouples the gears from each other by causing at least one of the gears to move in an axial direction of the gear. A determining section determines, on the basis of signals detected by rotation sensors, whether or not an end surface of a tooth of the axially moving gear lies between an end surface of a first tooth of the other gear and an end surface of a second tooth of the other gear. A driving section causes the gear to move in the axial direction on the basis of the determination result of the determining section and causes the gears to be coupled to each other.Type: GrantFiled: February 8, 2012Date of Patent: February 24, 2015Assignee: Hitachi, Ltd.Inventors: Akira Nishioka, Hiroyasu Kuniyoshi

Patent number: 8688359Abstract: There is provided an idle stop system that can more quickly restart with small noise in conducting idle stop. In preparation for a restart request during an engine inertial rotation, after a motor is rotated in a state where a starter motor is not coupled to the engine, a pinion is engaged with a ring gear during the motor is subjected to inertial rotation like the engine. In this situation, the rotational speed including future pulsation of the engine is estimated with the use of information on the crank angle, and a pinion pushing timing is controlled so that the pinion and the ring gear contact each other with a given rotational speed difference taking a delay time of a pinion pushing unit into consideration.Type: GrantFiled: August 2, 2011Date of Patent: April 1, 2014Assignee: Hitachi Automotive Systems, Ltd.Inventors: Hiroyasu Kuniyoshi, Akira Nishioka, Ryuu Kai, Kenichi Machida, Yoshiaki Nagasawa

Patent number: 8033714Abstract: A cylinder-shaped flow passage in which a first fluid flows includes an internal cylinder which is smaller in diameter than the flow passage. A swirl-generating stator having four vanes is radially fixed in the internal cylinder. A header space for supplying a second fluid is provided to the outer circumference of a wall surface of the internal cylinder in contact with flow separation areas which are formed along downstream surfaces of the swirl-generating stator as the first fluid runs into the swirl-generating stator. The wall surface of the internal cylinder is formed with openings through which the flow separation areas communicate with the header space. The second fluid supplied into the header space flows through the openings into the flow separation areas, and is diffused along the vanes of the swirl-generating stator to be swirled and mixed into the first fluid applied with swirling force by the swirl-generating stator.Type: GrantFiled: April 27, 2006Date of Patent: October 11, 2011Assignees: Hitachi High-Technologies Corporation, Babcock-Hitachi K.K.Inventors: Akira Nishioka, Kiyoshi Amou, Yoshihiro Sukegawa, Takehiko Kowatari, Yasunaga Hamada, Ikuhisa Hamada, Toshifumi Mukai, Yoshinori Taguchi, Hiroshi Yokota

Patent number: 6598245Abstract: An automatic water feed mechanism and method is provided by equipping a lavatory with a two dimensional sensor array such as a camera unit for monitoring a target area that a user may enter. An infrared emitter and an infrared detector can also be activated at low light levels. A two dimensional image signal can be processed and compared with a stored reference signal for activating the release of water. At a low ambient light, the infrared emitter unit can be activated to emit infrared rays which can then be detected when reflected by a user by the infrared detector. Such a detection can provide an alternative release of water.Type: GrantFiled: January 8, 2002Date of Patent: July 29, 2003Assignee: San-Ei Faucet Mfg. Co., LTDInventor: Akira Nishioka
