Abstract: A parking control system of a parking facility, the parking control system including: an acquisition unit configured to acquire behavior information on a user; an estimation unit configured to, based on the behavior information, estimate a probability of vehicle exit performed by the user; and an execution unit configured to, based on the probability, perform a process related to vehicle exit in the parking facility.

Abstract: A parking control system configured to perform a motion process to move a vehicle between a stopping area in which at least any one of getting in the vehicle and getting out of the vehicle is performed and a parking area in which a vehicle is parked, the parking control system including: a buffer control unit configured to perform a motion process to move a vehicle between the stopping area and a buffer section capable of having a plurality of vehicles arranged in the parking area; and motion process to move a vehicle between the buffer section and a parking section capable of having a plurality of vehicles arranged in the parking area including a region farther than the buffer section from the stopping area.

Abstract: In a fixing structure for a rolling bearing in which a bearing fixing ring is incorporated in a device and a rotating member is fixed to a bearing rotating ring using bolts, fastening areas with the bolts are set so that the natural frequency of the device as a whole is larger than the frequency of vibration resulting from the rotation of the rolling bearing. This prevents generation of noise or vibration in the rolling bearing.
