Patent number: 12040729Abstract: A motor control device includes an inverter circuit to convert a DC power source voltage into a three-phase AC voltage and supply the three-phase AC voltage to the three-phase motor and a controller to generate three-phase PWM signals based on three-phase duty command values updated at a predetermined updating cycle and control the inverter circuit based on the three-phase PWM signals. The controller is configured or programmed to shift, when duty command values of at least two phases of the three-phase duty command values updated at a first update timing are the same, the duty command value of one phase of the duty command values of the two phases by a predetermined shift amount and shifts a duty command value of the one phase of the three-phase duty command values updated at a second update timing which is an update timing next to the first update timing by the shift amount in a direction opposite to a shift direction at the first update timing.Type: GrantFiled: June 23, 2022Date of Patent: July 16, 2024Assignees: NIDEC CORPORATION, NIDEC ELESYS CORPORATIONInventors: Takashi Koikegami, Isao Sanbonmatsu, Akihiro Okamura, Tomohiro Fukumura, Kotaro Kataoka

Patent number: 8335846Abstract: The multi-functional peripheral judges whether or not the last display screen at the time of logout is usable as the initial display screen at the time of next login. Then, when the last display screen at the time of logout is not usable as the initial display screen at the time of next login, not information to specify the last display screen at the time of logout but a predetermined screen information is set to be transmitted to an authentication server. The authentication server manages information to specify the last display screen given from a multi-functional peripheral, and notifies the multi-functional peripheral of the last display screen information of the user to display the screen on the multi-functional peripheral when a user logs in the multi-functional peripheral next time.Type: GrantFiled: August 18, 2010Date of Patent: December 18, 2012Assignee: Sharp Kabushiki KaishaInventor: Akihiro Okamura

Patent number: 7193345Abstract: A collection-distribution ring comprises three busbars, each having a circular ring shape, which are integrally connected together with prescribed distances therebetween by an insulating resin. Coil connection terminals project inwardly in a radial direction and are alternately arranged in relation to the three busbars. External terminals project outwardly in the radial direction and are arranged to adjoin together at the prescribed position. These terminals are all exposed from surfaces of the insulating resin. A stator comprises the prescribed number of stator units that are arranged in a circumferential direction and are assembled together with the collection-distribution ring. Each stator unit comprises a core unit realizing magnetic teeth, an insulating member, and a coil. An outer terminal member electrically connects a first end of the coil and the coil connection terminal, and an inner terminal member provides electrical connections between second ends of the adjacent coils.Type: GrantFiled: September 3, 2002Date of Patent: March 20, 2007Assignee: Honda Motor Co., Ltd.Inventors: Satoru Shinzaki, Tatsuro Horie, Kenji Fukuda, Akihiro Okamura
