摘要： An airborne ultrasonic sensor is obtained in which a sensor body and a housing have an integrated structure, and which can reduce spurious waves which propagate through the housing to arrive at the sensor body. The sensor is provided with the sensor body that radiates ultrasonic waves into air and at the same time receives reflected waves from a reflection source which exists in the air, a transmission and reception device that drives the sensor body and at the same time obtains a distance to the reflection source or a propagation speed of sound based on the reflected waves, and the housing that has the sensor body fixedly secured thereto with an integrated structure. The housing has groove portions which are different in acoustic impedance from their surroundings. The groove portions are arranged obliquely regarding either one of a horizontal direction or a vertical direction of the sensor body.

摘要： A disk holding device is for use with a disk having a center hole. A disk holding mechanism with coupling levers is movable between a holding position and a release position, for engagement with an edge of the center hole when in the holding position, and for coming away from the edge when in the release position. A solenoid shifts the disk holding mechanism, to hold the disk by setting the disk holding mechanism in the holding position, and to enable loading or unloading of the disk by setting the disk holding mechanism in the release position. A separating projection is opposed to the edge when inserted in the center hole, for receiving the edge while the disk holding mechanism moves to the release position, to ensure separation of the disk from the disk holding mechanism.

摘要： An obstacle detection device includes one or more emitter ultrasonic sensors, each emitting an ultrasonic wave toward an obstacle, and one or more detection ultrasonic sensors for reception, each detecting a reflected wave from the obstacle. A control unit drives a specific one of the emitter ultrasonic sensors to cause it to emit an ultrasonic wave, stops the emission of the ultrasonic wave by the specific emitter ultrasonic sensor at the time that one of the detection ultrasonic sensors detects a reflected wave from the obstacle, and carries out detection of the obstacle and measurement of the distance to the obstacle from the time that the control unit stops the emission of the ultrasonic wave by the emitter ultrasonic sensor and the time that the reflected wave cannot be detected anymore.

摘要： A disk unit wherein a disk is inserted by a plurality of arms, the arms being able to convey two types of disks different in diameter while supporting an outer periphery edge of each of the disks. A disk is loaded to the interior of the disk unit by automatic loading, and a disk accommodated in the interior of the disk unit is unloaded to the exterior of the disk unit. The disk unit comprises a limit switch, the limit switch being actuated by an arm that is pressed by an outer periphery edge of a large diameter disk or a small diameter disk upon insertion of the disk from a slot of a bezel. The insertion of the large diameter disk or the small diameter disk is determined on the basis of the state of operation of the limit switch.
