Abstract: An object detection apparatus is arranged to detect the distance to the object and includes: a transceiver repeatedly transmitting a wave as an ultrasonic wave and receives a reflection wave of the transmission wave; a transmission controller controlling the transceiver to transmit the transmission wave; a distance calculator calculating a distance to the object, based on a time interval from a moment when the transceiver transmits the wave to a moment when the reflection wave is received; and a transmission timing controller controlling timing at which the transmission controller controls the transmission wave to be transmitted. Moreover, the transmission timing controller inserts at least one type of temporary waiting time between a transmission/reception period in which the transceiver transmits the transmission wave and receives the reflection wave and a next transmission/reception period, when a predetermined crosstalk identification condition is established based on the distance to the object.

Abstract: A motor includes a rotor fixed to a rotary shaft, a stator arranged so as to surround the rotor with a gap from the rotor in a radial direction orthogonal to an axis direction of the rotary shaft, and a case accommodating the rotor and the stator. The rotor includes a plurality of rotor cores made from a soft magnetic material, and a rotor fixing member that fixes the rotor cores. The stator includes a plurality of stator cores made from a soft magnetic material, a stator fixing member that fixes the stator cores, and coils wound around the stator cores, respectively. The motor includes at least two sets of the rotor and the stator, and the sets are stacked in an axis direction of the rotary shaft.

Abstract: In an axial gap motor, a rotor includes a plurality of rotor cores fixed in a circumferential direction of a rotor base, and a stator includes a plurality of stator cores fixed in a circumferential direction of a stator base, and coils wound around the stator cores. End faces of each of the rotor cores and end faces of the corresponding stator core are opposed to each other while being exposed to each other.
