Patent number: 9046145Abstract: A shock absorber in which a flow of hydraulic oil caused by sliding movement of a piston in a cylinder is controlled by a pilot type main valve and a pilot valve to generate damping force. The valve-opening operation of the main valve is controlled by adjusting the pressure in a pilot chamber with the pilot valve. A valve block and a solenoid block are connected together into one unit and inserted into a casing before being secured with a nut. At this time, an actuating rod of the solenoid block is engaged with a pilot valve member retained by a pilot spring and a fail-safe spring in a cylindrical portion of a pilot body of the valve block.Type: GrantFiled: May 24, 2012Date of Patent: June 2, 2015Assignee: HITACHI AUTOMOTIVE SYSTEMS, LTD.Inventors: Hiroshi Murakami, Osamu Yuno, Tomohiko Fujioka, Takashi Nezu, Shunsuke Mori

Patent number: 8599470Abstract: A suspended particle device is realized which enables control of the amount of light transmitted through a prescribed area, without any complicated switching circuit on a substrate. A suspension, containing charged particles and a disperse medium, is filled between an A-substrate and a B-substrate, and first and second electrodes are formed on the A-substrate. A DC voltage is applied across the first and second electrodes, to localize the charged particles on the second electrode side. Subsequently, an AC voltage is applied across the first and second electrodes to orient, while maintaining the localized state of the charged particles, the charged particles along a direction of an electric field. Light transmittance is lower in an area where the charged particles are present than in an area without charged particles, whereas, in the area where the charged particles are present, the light transmittance can be controlled by adjusting the AC voltage.Type: GrantFiled: July 25, 2011Date of Patent: December 3, 2013Assignee: Hitachi Chemical Company, Ltd.Inventors: Shunsuke Mori, Yoshiro Mikami, Toshiaki Kusunoki

Patent number: 8117836Abstract: A pressure keeping mechanism is provided downstream of a discharge port of a compressor. The pressure keeping mechanism is set to a small flow path area having only a bypass orifice until a pressure in a downstream pipe reaches a predetermined pressure after the operation is started, the pressure keeping mechanism is set to a large flow path area of a pressure keeping valve which is opened when the pressure exceeds the predetermined pressure and the bypass orifice, thereby changing the flow path area at least in two stages. The pressure in the upstream pipe which is almost closed by the pressure keeping valve can be thus increased at a dash and the pressure in a compression chamber can also be increased swiftly immediately after the compressor is started.Type: GrantFiled: September 29, 2008Date of Patent: February 21, 2012Assignee: Hitachi, Ltd.Inventors: Shunsuke Mori, Kazutaka Suefuji
