Patent number: 8082080Abstract: An electric power steering (EPS) apparatus 1 includes a motor 12, an EPS actuator 10, a torque sensor 14, and an ECU 11. The EPS actuator 10 uses the motor 12 as a drive source to apply assist force to a steering system, thereby assisting a steering operation. The torque sensor 14 detects a steering torque ? of the steering system. The ECU 11 controls the operation of the EPS actuator 10. Based on the steering torque ? detected by the torque sensor 14, the ECU 11 computes a basic shift amount ?ts_b of the assist force applied to the steering system. The ECU 11 determines which one of returning, holding, and turning is the state of the steering operation. When the state of the steering operation is returning or holding, the ECU 11 executes compensation control for correcting the steering torque ?, which is used in the computation of the basic shift amount ?ts_b of the assist force, thereby increasing the assist force applied to the steering system.Type: GrantFiled: June 2, 2009Date of Patent: December 20, 2011Assignee: JTEKT CorporationInventors: Masayuki Kita, Terutaka Tamaizumi, Akihiko Nishimura, Shinya Aono, Jun Hasegawa, Akira Nambu

Patent number: 8041377Abstract: A radio device is located far from other radio devices in a radio network system. The radio device determines a threshold WIth for detecting a strength equal to or more than the minimum strength of radio waves transmitted/received in a stable radio wave environment based on a plurality of reception signal strengths of Hello packets received from radio devices adjacent to the radio device. Then, if the number of radio devices adjacent to the radio device when the threshold WIth is introduced is less than a standard value (such as five), the radio device stores the adjacent radio devices in the neighbor list without introducing the threshold WIth, and then, maintains in the routing table the routing information of routes passing through the adjacent radio devices based on the neighbor list.Type: GrantFiled: September 27, 2007Date of Patent: October 18, 2011Assignees: NEC Communication Systems Ltd., Advanced Telecommunications Research Institute InternationalInventors: Satoko Itaya, Jun Hasegawa, Akio Hasegawa, Peter Davis, Tetsuya Ito, Akira Matsumoto, Naoto Kadowaki, Sadao Obana

Patent number: 7905215Abstract: A fuel supply apparatus includes a movable unit, a coil, a drive circuit portion, and a drive control portion. The drive circuit portion energizes the coil with a drive electric current of a first value such that the movable unit is displaced from an opening-side position to a closing-side position. The drive circuit portion energizes the coil with the drive electric current of a second value that is smaller than the first value such that the movable unit is held at the closing-side position. The drive control portion controls the drive circuit portion to change the drive electric current from the first value to the second value while the movable unit is being displaced toward the closing-side position based on energization of the coil with the drive electric current of the first value.Type: GrantFiled: June 4, 2009Date of Patent: March 15, 2011Assignee: DENSO CORPORATIONInventors: Yoshihito Suzuki, Tsutomu Furuhashi, Masahiro Yokoi, Jun Hasegawa

Patent number: 7890112Abstract: The route maintenance unit outputs a period setting request to the period setting unit when the communication unit normally receives a Hello packet for the first time. The period setting unit sets a link connection confirmation period in response to the period setting request and outputs the set period to the route maintenance unit. The route maintenance unit maintains a radio link between the radio device in which the route maintenance unit is provided and an adjacent device upon receiving a data packet other than a Hello packet from the adjacent radio device even if a Hello packet is not received in the link connection confirmation period. Consequently, route disconnection or switching occurs less often.Type: GrantFiled: September 4, 2007Date of Patent: February 15, 2011Assignees: NEC Communication Systems, Ltd., Advanced Telecommunications Research Institute InternationalInventors: Tetsuya Ito, Jun Hasegawa, Satoko Itaya, Akira Matsumoto, Hiroyuki Iizuka, Yuichiro Ezure, Akio Hasegawa, Peter Davis, Naoto Kadowaki, Sadao Obana

Publication number: 20110022270Abstract: A current command value computing section includes an integration control computing section. Based on an integration of the steering torque ?, the integration control computing section computes a steering torque integration control amount Iint*, which is a compensation component for increasing the assist force. The integration control computing section functions as a determining device that determines whether the vehicle is traveling forward in a straight line. When the determining device determines that the vehicle is traveling forward in a straight line, the integration control computing section outputs the steering torque integration control amount Iint* to an adder. The current command value computing section superimposes the steering torque integration control amount Iint* on a basic assist control amount Ias* computed by a basic assist control section, and outputs the obtained value, as a current command value Iq* corresponding to a target assist force, to an output section.Type: ApplicationFiled: April 15, 2009Publication date: January 27, 2011Applicant: JTEKT CORPORATIONInventors: Terutaka Tamaizumi, Hirozumi Eki, Shinya Aono, Jun Hasegawa, Masayuki Kita
