Patent number: 11973453Abstract: A first actuator and a second actuator each have a plurality of control calculation units provided redundantly and a plurality of motor drive units provided redundantly. In the first and the second actuators, the control calculation units of the systems paired with each other transmit and receive information to and from each other by a communication between the actuators. When a failure occurs in any system in either of the two actuators, or when a failure occurs in a communication between actuators in either system, the control calculation unit of each actuator of the system in which the failure occurred stops the motor drive control. Then, the motor drive control is continued by the control calculation unit of the normal system in both actuators.Type: GrantFiled: April 26, 2022Date of Patent: April 30, 2024Assignees: DENSO CORPORATION, TOYOTA JIDOSHA KABUSHIKI KAISHA, JTEKT CORPORATIONInventors: Hiroki Tomizawa, Masaharu Yamashita, Kenji Shibata, Yosuke Yamashita, Shoji Kubota, Yugo Nagashima, Yuji Fujita, Kenichi Abe

Patent number: 10419009Abstract: The variation of the oscillation frequency of an oscillator can be suppressed even in the case where the amount of interference with the oscillator accompanied by an amplifying operation of a power amplifier and the polarity are not constant. An oscillator is configured to be capable of oscillating at an oscillation frequency in accordance with control signals Vcont and FREQ_CTRL. A phase locked loop allows the oscillator to output an oscillation signal Vout in synchronization with a reference signal RELCLK using the control signal Vcont. A power amplifier amplifies the electric power of the oscillation signal Vout. A variation detection unit detects a variation with respect to the time change of the control signal Vcont after an amplifying operation is started by the power amplifier causing 3interference with the oscillator.Type: GrantFiled: April 11, 2018Date of Patent: September 17, 2019Assignee: RENESAS ELECTRONICS CORPORATIONInventor: Kenichi Shibata

Patent number: 8881781Abstract: A pneumatic tire capable of reducing air column resonance arising from circumferential grooves without changing the shape of unilaterally open-ended lug grooves. Lug grooves 20 are formed in land portions 15, which are defined by the circumferential grooves, and each of the lug grooves 20 consists of a lateral groove portion 21, which extends axially to open at one end into the circumferential groove and communicate at the other end with a sub-groove 12 provided in the land portion 15, and an oblique groove portion 22, which extends in a direction intersecting with the tire axial and circumferential directions to communicate at one end with the sub-groove 12 and terminate at the other end within the land portion 15. Also, the lateral groove portion 21 of the lug groove 20 is provided with a projection 23 protruding toward the tread surface from the bottom of the lug groove 20 and having a height smaller than the height H of the land portion 15 as measured from the bottom of the lug groove 20.Type: GrantFiled: February 17, 2009Date of Patent: November 11, 2014Assignee: Kabushiki Kaisha BridgestoneInventors: Takashi Ookawara, Kenichi Shibata

Patent number: 8538364Abstract: Gain setting can be performed at high speed while reducing DC offset due to a filter cutoff frequency changeover without the need for input signal muting. A filter circuit having first and second filters is capable of allowing settings of first and second cutoff frequencies. First and second filter switch circuits and a charging circuit including a charging resistor and a charging switch are provided. For a first time period, the first switch circuit is controllably turned on while the second switch circuit is controllably turned off, thereby providing the first filter function. For a second time period, the first switch circuit is controllably turned off while the second switch circuit is controllably turned on, thereby providing the second filter function. For the first time period, the charging switch is controllably turned on so that the second capacitor is charged via the charging resistor.Type: GrantFiled: May 28, 2010Date of Patent: September 17, 2013Assignee: Renesas Electronics CorporationInventors: Yusaku Katsube, Junichi Takahashi, Masaaki Yamada, Toshihito Habuka, Kenichi Shibata, Fumihito Yamaguchi

Patent number: 8531244Abstract: A high frequency signal processing device is capable of carrying out high-accuracy modulation by a PLL circuit. A digital loop is configured in addition to an analog loop having, for example, a phase frequency detector, a charge pump circuit, and a loop filter. A digital calibration circuit is provided which searches for the optimal code set to a capacitor bank upon frequency modulation. Upon the search for the optimal code, a calibration controller first sets a division ratio based on a center frequency to a divider and determines the value of a voltage control signal using the analog loop. Then, the loop filter holds the value of the voltage control signal therein, and a division ratio corresponding to a “center frequency+modulated portion” is set to the divider, thereby operating the digital loop. The optimal code is obtained by a convergent value of the digital loop.Type: GrantFiled: June 22, 2011Date of Patent: September 10, 2013Assignee: Renesas Electronics CorporationInventors: Kenichi Shibata, Toshiya Uozumi
