Patent number: 10686395Abstract: In a brushless motor control device, a microcontroller determines a current-on phase of a motor based on zero crossing detected by a position detection circuit, and the inverter circuit generates a voltage for current-on to the determined current-on phase. In a case in which zero crossing has been successively detected plural times, in a phase that was switched from the current-on phase to a current-off phase, in a PWM control cycle after a predetermined masking period, the microcontroller controls to interrupt current to coils of all phases of the motor body. In a state in which current-on has been interrupted, the microcontroller determines the current-on phase based on zero crossing detected in one of the three phases, the inverter circuit generates the voltage for current-on for the determined current-on phase and restarts current-on to the coils.Type: GrantFiled: April 5, 2019Date of Patent: June 16, 2020Assignee: DENSO CORPORATIONInventor: Masakazu Matsumoto

Patent number: 9964278Abstract: A reflecting surface of a reflector has a structure where a plurality of reflecting elements are arranged in rows in an up-and-down direction, and the reflecting elements are arranged as a plurality of sets in a left-and-right direction. The surface of each reflecting element is composed of a curved surface having a horizontal section curvature larger than a vertical section curvature. Thus, a horizontally long light distribution pattern may be easily formed by light reflecting from each reflecting element. Each reflecting element is connected to each of four reflecting elements which are adjacent thereto in the left-and-right direction and are shifted therefrom in the up-and-down direction, through a boundary line extending from a vertical plane in an inclined direction in the left-and-right direction. Thus, the horizontally long light distribution pattern formed by the light reflecting from each reflecting element becomes a bright light distribution pattern having four chipped corners.Type: GrantFiled: June 10, 2016Date of Patent: May 8, 2018Assignee: Koito Manufacturing Co., Ltd.Inventors: Masakazu Matsumoto, Takayuki Suzuki
