Abstract: An optical deflector includes: a reflecting section driven to rotate or oscillate around a drive axis; and a diffraction section configured to diffract light reflected by the reflecting section. The reflecting section is driven to change a first incident angle of light, around the drive axis, incident on the diffraction section from the reflecting section. The diffraction section changes a first emission angle of light emitted from the diffraction section, around a first axis perpendicular to the drive axis and a predetermined direction defined to extend from the reflecting section toward the diffraction section perpendicularly to the drive axis. The diffraction section is driven about the drive axis together with the reflecting section to maintain a second incident angle of light incident on the diffraction section from the reflecting section, around the first axis.

Abstract: A refrigeration cycle device includes a compressor, an upstream branch portion, a heating portion, a decompression portion, a bypass passage, a bypass flow adjustment portion, and a mixing portion. The mixing portion mixes a bypass side refrigerant flowing out from the bypass flow adjustment portion with a decompression-portion side refrigerant flowing out from the decompression portion, and causes the mixed refrigerant to flow to a suction port side of the compressor. The mixing portion mixes the bypass side refrigerant and the decompression-portion side refrigerant such that an enthalpy difference obtained by subtracting an enthalpy of an ideal homogeneously mixed refrigerant from an enthalpy of a suction side refrigerant actually sucked into the compressor is equal to or less than a predetermined reference value.

Abstract: A steering control device includes a control circuit configured to control driving of a reaction force motor that generates steering reaction force applied to a steering wheel in which power transmission with turning wheels of a vehicle is separated. When a vehicle power source is turned on, the control circuit requests a vehicle control device to stop traveling of the vehicle when information is exchanged with the vehicle control device in a manner that does not follow a predetermined pattern.

Abstract: An inverter device includes an inverter outer peripheral wall, a high voltage board, a control board, and an arm switch unit. The inverter outer peripheral wall has an inner peripheral surface. The high voltage board and the control board extend in a direction orthogonal to an axial direction. In the high voltage board and the control board, an outer peripheral end extends in a ring shape in a circumferential direction along the inner peripheral surface. In the arm switch unit, a drain terminal and a source terminal are connected to the high voltage board, and a gate terminal and a driver source terminal are connected to the control board. Multiple arm switch units are arranged in the circumferential direction along the outer peripheral end.

Abstract: An optical ranging device detects a distance to a target by using a round-trip time of light. The optical ranging device includes a light receiving module that is a plate-shaped member on which detectors are arranged and responds to sensing light having a predetermined wavelength, light emitting elements configured to emit the sensing light, and an aperture module disposed upward of the light receiving module. The aperture module is a plate-shaped member having openings through which reflected light passes toward the detectors. The reflected light is the sensing light reflected by the target. The light emitting elements are provided on portions of the aperture module where the openings are not provided on the aperture module.

Abstract: To a first electronic control unit, three or more sensors excluding one predetermined sensor are connected. To a second electronic control unit, two sensors, which include one common sensor, of the three or more sensors, are connected. When the first electronic control unit does not determine that a sensor in a normal state is present among the three or more sensors, and the second electronic control unit determines that both of the two sensors are in the normal state, the electronic control unit controls the brake circuit based on the operation amount detected by at least one of the predetermined sensor or the common sensor.
