Publication number: 20140349811Abstract: A vehicle driving system in which a clutch is disposed between an engine output member and an automatic transmission and the clutch is used as a start clutch that is slip-controlled when a vehicle starts. When a lubricant relay valve is switched to the communicating position, oil from the pressure-regulating oil passage is supplied to the clutch via the input port, the output port, and the clutch lubricant passage. When the lubricant relay valve is switched to the cutoff position, the oil from the pressure-regulating oil passage is supplied to the clutch via the orifice and the clutch lubricant passage, the feedback pressure of the feedback port is increased, the communication rate between the pressure-regulating port and the back-pressure port is increased, and the amount of lubricant supplied from the back-pressure oil passage to the lubrication portion of the automatic transmission is increased.Type: ApplicationFiled: February 27, 2013Publication date: November 27, 2014Inventors: Shinya Ichikawa, Kazuyuki Noda, Kazuhito Enomoto, Takayoshi Yonezu

Publication number: 20110067962Abstract: A vehicle hydraulic control device for driving a parking rod to a parking disengagement position and a parking engagement position, and switching a shift range at least between a parking range and a non-parking range by switching an engagement state of a parking gear and a parking pole. The vehicle hydraulic control device includes a parking cylinder and a switch valve. The parking cylinder receives an oil pressure for driving the parking rod to the parking disengagement position. The switch valve is driven based on an electric actuator and switches an operation state between a parking disengagement state in which a source pressure from an oil pressure supply source is supplied to the parking cylinder as a disengagement pressure for disengaging the parking gear and the parking pole from each other, and a parking engagement state in which the disengagement pressure is not supplied to the parking cylinder.Type: ApplicationFiled: August 24, 2010Publication date: March 24, 2011Applicant: AISIN AW CO., LTD.Inventors: Takayoshi YONEZU, Yuhei Yoshioka, Kazuyuki Noda, Kazuhito Enomoto

Patent number: 7637336Abstract: Drain holes are arranged in positions offset from valve holes of a valve body. The drain holes have a long chimney-shaped space such that even if insulation material, that has peeled off of an electric motor, is suspended in oil, it is less likely to enter drain chambers through the drain holes.Type: GrantFiled: March 17, 2006Date of Patent: December 29, 2009Assignees: Aisin AW Co., Ltd., Toyota Jidosha Kabushiki KaishaInventors: Kazuhito Enomoto, Kiyotomo Mirua, Satoru Wakuta, Kazuhisa Ozaki, Nobuyuki Nagashima, Masato Fujikawa, Tomoyuki Maruyama, Masatoshi Adachi

Patent number: 7466359Abstract: An image-pickup apparatus for capturing an object includes a distance calculating unit for measuring a phase difference (time difference) from the emission of light from a light emitting unit to the reception of reflected light by a light receiving unit for each unit composed of a predetermined number of adjacent pixels of the object to calculate a distance from the image-pickup apparatus to each corresponding pixel unit of the object, and an image processing unit for corresponding the distance calculated in units of the predetermined number of pixels to the image captured by the light receiving unit. The image processing unit supplies a display unit with only pixels corresponding to a predetermined range in the image generated by the distance calculating unit to display the pixels in units of the predetermined number of pixels on the display unit.Type: GrantFiled: March 24, 2005Date of Patent: December 16, 2008Assignee: Hitachi Kokusai Electric Inc.Inventors: Kazuhito Enomoto, Nobuaki Fujimura

Patent number: 7460156Abstract: A method and apparatus for transmitting a signal between a television camera and a video apparatus. When time-division multiplexing parallel image signals and transmitting them as a serial signal from the camera side to the video apparatus side, a control signal destined from the camera to the video apparatus is also time-division multiplexed. Furthermore, a plurality of kinds of trigger signals may be time-division multiplexed into one serial signal and transmitted from the video apparatus to the camera.Type: GrantFiled: March 17, 2004Date of Patent: December 2, 2008Assignee: Hitachi, Ltd.Inventors: Kazuhito Enomoto, Nobuaki Fujimura, Kazuhisa Yoshihara, Katsumasa Ueno

Patent number: 7128676Abstract: A failsafe hydraulic circuit designed to avoid simultaneous engagement of two friction engagement elements (e.g., clutches, brakes, etc.) incorporated in a speed change apparatus of a motor vehicle or the like. If a first failsafe valve is in the open position state and a first engaging pressure is supplied to a first hydraulic servo via the first failsafe valve, the first engaging pressure is also input to a first oil pressure switch via a second failsafe valve being in the closed position state. Therefore, using the first oil pressure switch, it can be detected that the first engaging pressure is supplied to the first hydraulic servo. Furthermore, if the first engaging pressure is, for example, greater than the set pressure of the first oil pressure switch, this situation can also be detected. Such detections provide confirmation of normal operation of the first failsafe valve and the second failsafe valve.Type: GrantFiled: October 29, 2004Date of Patent: October 31, 2006Assignees: Aisin AW Co., LTD, Toyota Jidosha Kabushiki KaishaInventors: Seiichi Kinugasa, Masanori Onoda, Kazuhito Enomoto, Kiyotomo Miura, Naoyuki Fukaya, Satoru Wakuta, Masatoshi Adachi, Akira Murakami
