Abstract: A wearable device includes a sensor device and a clothes to which the sensor device is attached. The clothes includes a clothes body and an insertion and extraction portion that has an opening formed in the clothes body and enables the sensor device to be inserted into or extracted from the clothes body. The sensor device includes a humidity sensor configured to measure humidity in the clothes body and a housing having a first region exposed to an inside of the clothes body and a second region exposed to an outside of the clothes body, while the sensor device is inserted from the insertion and extraction portion into the clothes body. The humidity sensor is accommodated in the first region of the housing.

Abstract: A vehicle periphery display control system displays peripheral images of a vehicle which are captured by a plurality of cameras mounted on the vehicle in respective different positions thereon. A storage medium stores road configuration information of a road. A positioning unit identifies the present position of the vehicle on the road. A image switching decision unit selects either one of images captured by the cameras based on specific road configuration information of a peripheral area around the vehicle, which includes the present position identified by the present position identifying unit, of the road configuration information stored in the storage medium. The image switching decision unit controls a display unit to display the image selected by the selecting unit.

Abstract: A rotary piston vacuum pump has a rotor eccentrically disposed in a cylinder and mounted therein for revolution in rolling contact with the cylindrical inner peripheral surface of the cylinder so that a crescent-shaped space is defined between the rotor and the cylinder and moved around the axis of the cylinder. A vane is radially reciprocally mounted in a vane chamber having an inner end open to the cylindrical inner peripheral surface of the cylinder. The vane has an inner end in sliding contact with the outer peripheral surface of the rotor to divide the crescent-shaped space into a suction chamber in communication with a suction port and a discharge port to be communicated with a discharge port having an inner end open in a wall of an outer part of the vane chamber.
