Abstract: A known pattern comparison type phase difference detection unit (12) detects a phase difference between a known pattern extracted from a received signal and a true value of the known pattern as a first phase difference. M indicates the number of modulation phases in a phase modulation method of the received signal. An M-th power type phase difference detection unit (13) removes a modulation component by raising the received signal to M-th power, and detects phase variation from a modulation phase point used for mapping on a transmission side, as a second phase difference. A phase compensation unit (11) compensates phase variation of the received signal based on an addition result of the first phase difference and the second phase difference.

Abstract: The present invention provides a cleaning unit that is attached to a vehicle and cleans an outer lens configured to cover a light source for illuminating an outer side of the vehicle and form part of an outer surface of the vehicle, the cleaning unit including a tank configured to reserve a washer fluid for cleaning the outer lens, and a supply unit provided above the outer lens and configured to supply the washer fluid reserved in the tank by dropping the washer fluid on the outer lens.

Abstract: A shift actuator of the present invention includes a first and a second fluid pressure chamber for providing fluid pressure to each of a first and a second piston defined in a cylinder and a shift operating member inserted and disposed between the first piston and the second piston to move back and forth along the axial direction. On a side surface to the axial direction of the cylinder, an opening portion to which the shift operating member is inserted is formed. The opening portion is provided opening only to a part of the circumferential direction of the cylinder, and a lower end of the opening portion in a circumferential direction of the cylinder reaches a just under position in the vertical direction of the cylinder. This enables to discharge foreign matters included in hydraulic oil in the cylinder according to a stroke of the piston, with a simple configuration.
