A terminal device includes: a tilt sensor that detects a tilt; a communication unit that transmits a signal according to the tilt detected by the tilt sensor; and a display unit that displays a status of charging performed according to the tilt detected by the tilt sensor. The rotation unit includes a main shaft that is rotated around its longitudinal axis by means of a rotating motor. A sealing material may applied between the neck and the cap, to adhere the same. The overall conversion process is enhanced by calculating conditions to optimize recovery of both oil and bitumen. The sensor device uses a ratio of the amount of the received light by the first light reception element and the amount of the received light by the second light reception element to determine wetting on the windshield.
