Abstract: A parking assist device is used for a vehicle on which a power receiving coil including a first coil and a second coil is mounted. The parking assist device includes a hardware processor functioning as an acquisition unit and a vehicle control unit. The acquisition unit serves to acquire route information for parking the vehicle at a facing position where a power feeding coil and the first coil of the power receiving coil face each other. The vehicle control unit serves to perform control of parking the vehicle by using the route information. The power receiving coil is mounted on the vehicle such that a distance between a center position of the first coil and a center position of the vehicle in a vehicle length direction becomes shorter than a distance between a center position of the second coil and the center position of the vehicle.

Abstract: A high frequency wireless circuit apparatus is formed by connecting a phase shifter between an antenna duplexer and a low noise amplifier, so that the impedance of the receiving terminal of the antenna duplexer at a transmission frequency and the input impedance of the low noise amplifier may not be matched in complex conjugates of each other. Therefore it prevents the transmission output passing through the receiving terminal of the antenna duplexer and the interference signal entered through the antenna from making the cross modulation in the low noise amplifier. Thus it improves the reception sensitivity and immunity to interference signals of the high frequency wireless circuit apparatus at the same time.

Abstract: A particle size distribution measuring apparatus includes a source of laser light for providing a laser beam to a sample cell that can hold a sample to be measured. A condenser lens converges the laser beam towards the sample cell along an optical axis.

An array of detectors can be operatively positioned on a substrate with appropriate amplifying multiplying and analog to digital conversion capacity for measuring light intensity at relatively large scatter angles. The outputs of the ring detector unit and the array of detectors can be used to determine the particle size distribution of particles in the sample.
