  • Publication number: 20210149000
    Abstract: A magnetic sensor includes a magnetic sensor tip that includes a magnetoresistive effect element and a sealed part. The magnetoresistive effect element includes a free layer and a pinned layer. The sealed part has a first surface and a second surface, which is opposite the first surface. The shape of the sealed part in the plan view from the first surface side is substantially quadrilateral. The substantially quadrilateral shape has a first side and a second side, which are substantially parallel to each other. In the plan view, from the first surface side of the sealed part, the magnetization direction of the pinned layer, in a state in which the external magnetic field is not applied on the magnetoresistive effect element, is inclined with respect to an approximately straight line found through the least squares method using a plurality of points arbitrarily set on the first side.

  • Patent number: 10953794
    Abstract: A loudspeaker 14 outputs a warning sound for announcing the presence of a vehicle to the outside of the vehicle. A travel start detection unit 122 detects travel start of the vehicle. A sound pressure control unit 124 controls sound pressure of the warning sound to be output from the loudspeaker 14, depending on travel status of the vehicle. The sound pressure control unit 124 makes the loudspeaker 14 output the warning sound during stopping of the vehicle, and increases the sound pressure of the warning sound upon detection of travel start of the vehicle. This makes it possible to announce the travel start of a low-noise vehicle such as an electrically powered vehicle, without making the surroundings feel unnatural.
