Abstract: In a motor, a dynamic pressure gas bearing is prevented from seizing when the motor shaft and a sleeve contact each other. The number of rotations of a rotating body with respect to a case is maintained substantially constant both before and after contact. Auxiliary bearings are arranged in series with the gas bearing. A non-contact detent torque generation mechanism in parallel with the auxiliary bearings suppresses rotation in the auxiliary bearings. The sum of a predetermined detent torque generated by the torque generation mechanism during a rotation suppression time and the friction torque of the auxiliary bearings is smaller than the magnitude of an adhesion-time contact friction torque generated when the motor shaft and sleeve adhere to each other and is greater than the magnitude of a rotation-time viscous friction torque of the dynamic pressure gas bearing while the motor shaft and sleeve are spaced from each other.

Abstract: An X-ray inspection device achieves a high cooling effect without using an expensive air conditioner and is excellent in cleaning property. The inside of a first case of an X-ray inspection device is separated into plural cooling partitions by separation walls by the use limit temperature and the like, and heat sources respectively having intrinsic use limit temperature are stored in respective partitions. Because a flow passage of air is set inside the cooling partition so that the heat sources having low use limit temperature are disposed upstream of the heat sources having high use limit temperature, the cooling efficiency is excellent. A heat absorption member of a heat exchange device exists inside the first case, and a heat radiation member exists inside a second case communicating with the external air. Because there is no protrusion of the heat radiation member as the total cases, cleaning property is excellent.
