    Abstract: An apparatus includes a conduit configured to circulate magnetic fluid, and a magnetic field generator that applies a magnetic field to the magnetic fluid. The conduit includes at least four areas of a first conduit area in which the magnetic fluid receives heat from a heating unit, a second conduit area from the first conduit area to a cooling unit, a third conduit area in which the magnetic fluid is cooled by the cooling unit, and a fourth conduit area from the cooling unit to the heating unit. When the apparatus is used, a volume of the magnetic fluid in one of the first to fourth conduit areas, in which a flow direction of the magnetic fluid coincides with a gravity direction, is larger than that of another conduit area, in which the flow direction of the magnetic fluid does not coincide with the gravity direction.

  • Patent number: 11867926
    Abstract: An optical unit that corrects a shake of an optical module includes: a movable portion having a holder that holds the optical module; and a fixed portion that rotatably supports the movable portion. The movable portion is rotatable relative to the fixed portion in first-third rotation directions correspondingly centered on first-third axes which correspondingly extend in first-third directions. The first direction is parallel to an optical axis direction of the optical module in a state in which the movable portion is stationary. The first direction, the second direction, and the third direction are perpendicular to each other. The movable portion further includes a protrusion protruding toward the fixed portion from an end of the holder closer to the fixed portion in the optical axis direction. The fixed portion includes a support portion that rotatably supports the protrusion.

  • Publication number: 20230169775
    Abstract: If there is a detection point that is erroneously recognized as an obstacle even though the detection point indicates a control-target vehicle, an obstacle that does not exist has been detected near the control-target vehicle. Consequently, the control-target vehicle might become unable to autonomously travel in an attempt to avoid a collision with the erroneously recognized obstacle. Considering this, an object indicated by a detection point that is detected by a road-side sensor and that exists within a certain distance range from a position of a control-target vehicle specified by an image recognition camera of a road-side unit, is not regarded as an obstacle.
