Patent number: 7594387Abstract: A gas turbine which can be easily employed in an area where it is hard to obtain a sufficient amount of water, such as an isolated island. Heated and pressurized heavy oil and water in a supercritical state are mixed with each other in a modifying unit to produce fuel-purpose modified oil. The fuel-purpose modified oil is depressurized by a depressurizing valve. Due to a temperature fall caused by adiabatic expansion with the depressurization, the fuel-purpose modified oil is brought into a two-phase state where moisture is in a gas phase (steam) and modified oil is in a liquid phase. The fuel-purpose modified oil is separated into the steam and the modified oil by a gas-liquid separator. The separated steam is condensed to water in a condenser and returned to a water supply line. The modified oil in the liquid phase is supplied to a combustor, thereby driving a gas turbine.Type: GrantFiled: July 12, 2005Date of Patent: September 29, 2009Assignees: Hitachi, Ltd., Petroleum Energy CenterInventors: Shinichi Inage, Nobuyuki Hokari, Osami Yokota, Hirokazu Takahashi, Masahiko Yamagishi

Patent number: 7591983Abstract: The invention is intended to produce high-pressure light fuel gas with good combustibility by contacting and reacting high-temperature, high-pressure water and heavy oil with each other in a contact-reaction unit to extract light oil components from the heavy oil and to remove metals. The high-temperature, high-pressure water and the heavy oil are introduced to the contact-reaction unit for contact and reaction with each other therein. Heavy oil components not dissolved in the high-temperature, high-pressure water are separated by precipitation from hydrocarbon gases and light oil components which are dissolved in the high-temperature, high-pressure water. The separated heavy oil components are burnt or incinerated without any further modification.Type: GrantFiled: August 4, 2004Date of Patent: September 22, 2009Assignees: Hitachi, Ltd., Petroleum Energy CenterInventors: Hirokazu Takahashi, Shinichi Inage, Nobuyuki Hokari, Masahiko Yamagishi, Akinori Hayashi, Osami Yokota, Youji Ishibashi

Patent number: 7593225Abstract: In the disk array system, in the basic chassis, HDD modules are installed from a front surface in a front part of a backboard, and duplex CTL modules are installed up and down from a rear surface in a rear part, and duplex power source modules containing fans are installed in the left and right sides thereof. By the operation of the fans, in the rear part, the cooling air flows separately into each CTL module and into each power source module, and the cooling air having passed through the area of the duct by a block in the CTL module is drawn by the fans in the power source module through a ventilation hole and is then exhausted outside. The cooling air flow path to the plurality of ICs is divided by the block. The rotation speed of the fans is controlled by using a temperature sensor.Type: GrantFiled: January 30, 2008Date of Patent: September 22, 2009Assignee: Hitachi, Ltd.Inventors: Tsuyoshi Sasagawa, Hirokazu Takahashi, Takahiko Iwasaki, Taro Takahashi, Chikazu Yokoi

Publication number: 20090178168Abstract: In a two-dimensional probe array, an interval between the leading ends of probes adjacent to each other in an X direction is made shorter than that between the leading ends of probes adjacent to each other in a Y direction. Thus, the leading ends of the probes are arranged to form a lattice wherein many rectangles are arranged. Furthermore, the lowest resonance frequency of an actuator which moves a recording medium in the X direction is set higher than the lowest resonance frequency of an actuator which moves the recording medium in the Y direction. At the time of recording or reading information, the recording medium is reciprocated in the X direction at a frequency substantially equal to the lowest resonance frequency of the actuator.Type: ApplicationFiled: March 30, 2007Publication date: July 9, 2009Inventors: Takanori Maeda, Jun Suzuki, Atsushi Onoe, Hirokazu Takahashi, Kiyoshi Tateishi
