    Abstract: A drive device for controlling a power switching element to turn on and off includes: an on-side circuit performing an on operation of the power switching element; an off-side circuit performing an off operation of the power switching element; and a temperature detector detecting a temperature. At least one of the on-side and off-side circuits includes a current path for supplying or drawing a gate current of the power switching element and a switch circuit for switching the gate current. The switch circuit transitionally changes the gate current based on the temperature of the power switching element when the switching circuit switches the gate current.

    Abstract: A discharge circuit discharges a smoothing capacitor that smooths a DC voltage through a plurality of resistive elements mounted on a substrate. The discharge circuit includes a series connection of at least three resistive elements spaced apart from each other in a first direction and connected in series by wires. The resistive element positioned more centrally in the first direction, included in the series connection, has a lower resistance value. The resistive elements adjacent to each other in the first direction and included in the series connection are displaced from each other in a second direction perpendicular to the first direction.

    Abstract: A detection apparatus includes a base part, a bearing, a discoid rotating part for detection, and a displacement detection unit. The bearing has a first bearing member fixed to a rotating object, and a second bearing member fixed to the base part. The rotating part for detection is provided so as to rotate together with the first bearing member and extends radially outward of the bearing with respect to the first bearing member. The displacement detection unit is provided at a position in the base part which is radially away from the bearing and faces the rotating part for detection in an axial direction of the bearing. Moreover, the displacement detection unit is configured to output a voltage signal according to displacement of the rotating part for detection in the axial direction and displacement of the rotating part for detection in a direction perpendicular to the axial direction.

    Abstract: A vehicular device includes a bearing, an annular detection target, a planar receiving coil extending in a direction intersecting an axial direction of the bearing and provided at a position facing the detection target in the axial direction in a state of not contacting the detection target, and an excitation coil to which an AC excitation voltage is supplied. The detection target is provided to rotate with the rotation of the wheel of the vehicle. When an excitation voltage is supplied to the excitation coil, a voltage is induced in the receiving coil. The vehicular device includes a parameter calculation section for calculating a rotational speed of the wheel based the output voltage signal from the receiving coil.

    Abstract: A detection device for vehicles includes a base section fixed to a body of a vehicle, and a bearing having an outer ring member, an inner ring member, and rolling elements, which rotatably supports a wheel of the vehicle against the base section. A first bearing member of the outer ring member and the inner ring member is fixed to the wheel, and a second bearing member of the outer ring member and the inner ring member is fixed to the base section. The detection device includes a disk-shaped rotating section for detection that extends radially outward of the bearing with respect to the first bearing member, and a displacement detection section that outputs a signal in response to an axial displacement of the rotating section for detection.
