Publication number: 20190291599Abstract: An electric power supply apparatus includes a first power supply unit, a second power supply unit, diodes, detection units, and an electric power control unit. The first power supply unit and the second power supply unit supply electric power to a thruster which is a load. The diodes are provided in the first power supply unit and the second power supply unit, respectively, to restrict reverse flow of currents to the power supply units. The detection units are provided between the first power supply unit and the thruster and between the second power supply unit and the thruster, respectively, to detect at least one of a voltage and a current. The electric power control unit controls electric power transmission between the first power supply unit and the second power supply unit based on detection values of the detection units.Type: ApplicationFiled: March 11, 2019Publication date: September 26, 2019Inventors: Shinji ANDOU, Satoru YOSHIKAWA, Tetsuji MITSUDA

Patent number: 10220953Abstract: In an aerial vehicle, a malfunction determiner determines whether there is a malfunction in one of thrusters of the aerial vehicle. A flight controller activates the thrusters, and controls the output of each of the thrusters. The flight controller deactivates, when it is determined that there is a malfunction in one of the thrusters as a malfunctioned thruster, the malfunctioned thruster. The flight controller deactivates a selected thruster in the thrusters; the selected thruster being paired to the malfunctioned thruster, and controls the active thrusters except for the deactivated thrusters in all the thrusters to make the flight attitude of the aerial vehicle stable. The flight controller controls the active thrusters to cause the aerial vehicle to land while maintaining the flight attitude of the aerial vehicle being stable.Type: GrantFiled: December 2, 2016Date of Patent: March 5, 2019Assignees: SOKEN, INC., DENSO CORPORATIONInventors: Hiroki Ishii, Koji Kawasaki, Takenori Matsue, Shinji Andou, Hiroyasu Baba

Patent number: 9391472Abstract: A battery charger of a battery charging apparatus is disposed on an exterior case of an engine in such a manner that a generated heat is transferred therebetween. An ECU drives a cooling system when an engine temperature and temperature of the battery charger satisfy a predetermined cooling temperature condition. A cooling capacity for cooling the battery charger is improved by establishing a heat radiation passage to radiate a heat from the battery charger efficiently.Type: GrantFiled: September 21, 2012Date of Patent: July 12, 2016Assignees: DENSO CORPORATION, NIPPON SOKEN, INC.Inventors: Seiji Iyasu, Shinji Andou, Sadahisa Onimaru, Kazuyoshi Obayashi

Patent number: 9067477Abstract: A power supply device includes a refrigeration cycle having a compressor, a motor, an inverter-integrated charger, a heat exchanger unit, and a controller having a determining unit. The inverter-integrated charger selectively controls operation of the motor using electrical power of a battery and charge of the battery with external power. The heat exchanger unit cools a cooling-necessary part of the inverter-integrated charger using refrigerant in the refrigeration cycle. When the vehicle is stopped and the battery is charged with the external power, the controller makes the inverter-integrated charger serve as: a charger to perform the charge of the battery; or an inverter to control the operation of the motor, thereby driving the compressor, upon determination that the cooling-necessary part needs to be cooled by the determining unit.Type: GrantFiled: April 17, 2012Date of Patent: June 30, 2015Assignees: DENSO CORPORATION, NIPPON SOKEN, INC.Inventors: Sadahisa Onimaru, Shinji Andou, Seiji Iyasu, Kazuyoshi Obayashi, Akira Sakamoto, Shigeru Kawano

Publication number: 20120314461Abstract: A power converter that is able to lower the level of switching noise in a wide frequency range is disclosed. In detail, the power converter converts an input power by controlling a switching element on the basis of a switching frequency discrete pattern. The switching frequency discrete pattern is composed in such a manner that a main discrete pattern and a sub discrete pattern are synthesized. The main discrete pattern is regulated by a plurality of transitionally discrete frequencies. Also the sub discrete pattern is regulated by a plurality of transitionally discrete frequencies in which a gap of the magnitude among consequent frequencies is smaller than that of the main discrete pattern.Type: ApplicationFiled: June 8, 2012Publication date: December 13, 2012Applicant: DENSO CORPORATIONInventors: Satoru YOSHIKAWA, Seiji Iyasu, Shinji Andou, Shinji Ohoka, Jun Ishii

Patent number: 6813967Abstract: To reduce entire length and radial dimension of a starter, the starter includes a driving lever composed of a lever body and a lever pin as a pivot center of the driving lever body. Further, the lever pin is disposed close to a center case in the radial direction. The dimension between supporting positions of both arm portions supporting the lever pin is set large. To provide the waterproof structure of a starter, a projection provided on a lever seal is inserted into a positioning hole of a lever holder in a lever assembly of a starter. Further, a tip of the projection comes in contact with a peripheral surface of a lever pin at a lower side than the center of the lever pin.Type: GrantFiled: May 5, 2003Date of Patent: November 9, 2004Assignee: Denso CorporationInventor: Shinji Andou
