摘要： An apparatus for detecting obstructions behind a vehicle, employing ultrasonic waves is disclosed. The apparatus comprises an ultrasonic transmitting and receiving device disposed on the rear portion of the vehicle, an electric motor for rotating the transmitting and receiving device at a constant velocity, an angle sensor for detecting the rotating angle of the transmitting and receiving device and a sonar circuit for emitting ultrasonic waves through the transmitting and receiving device at predetermined rotating angles, receiving ultrasonic waves reflected from obstructions through the transmitting and receiving device at predetermined rotating angles and measuring the distance to the obstructions from the time taken from the transmission to the reception of the ultrasonic waves. According to the apparatus of the present invention, the distances to obstructions in every region behind the vehicle can be accurately and easily measured by rotating a single transmitting and receiving device by means of the electric motor at a constant velocity.

摘要： An ultrasonic transmitting and receiving device comprises a bimorph vibrator including two piezoelectric elements each connected electrically to the corresponding one of a plurality of terminals for receiving and delivering electric signals and a metallic member made of a thin metal plate and including a flat plate portion and a cylindrical portion extending from the circumferential periphery of the flat plate portion. The flat plate portion is placed between the piezoelectric elements and the cylindrical portion increases in outer diameter as it becomes distant from the flat plate portion.

摘要： A hollow tubular handle is connected at one end to a pressurized water supply and carries a sprinkler head at its other end. A brush attached to the sprinkler head is formed with a hole through which water from sprinkler head passes without contact with the brush. A tubular member extends from the sprinkler head partially through the hole in the brush to prevent the bristles of the brush from being bent into the flow from the sprinkler head when the brush is pressed against a surface to be washed such as an automobile body.
摘要翻译：中空管状手柄在一端连接到加压水源，并在其另一端承载喷头。附着在喷洒头上的刷子形成有一个孔，喷洒头的水通过该孔穿过而不与刷接触。管状构件从喷洒头部分地延伸穿过刷子中的孔，以防止当刷子被压靠在诸如汽车车身的待清洁表面上时刷子的刷毛弯曲成来自喷洒头的流动。
