An ultrasonic sensor () includes a transmission and reception unit () for transmitting and receiving an ultrasonic wave, a holder () and an attachment () for fixing the transmission and reception unit () to the bumper () of a vehicle, and light source units () mounted in a back side of the bumper (). The holder () is shaped so as to be exposed on a surface of the bumper (), and guides light beams emitted by the light source units () to the surface of the bumper (), to project the light beams from a light projecting surface () to the outside of the vehicle.

Ultrasonic sensor and obstacle detection apparatus

In a headlight for in-vehicle use, an LED serving as an optical source is provided in which one edge side of its light-emitting face is formed into a linear portion and placed at a side of an optical axis so that the center of the light-emitting face is displaced from the optical axis. A projection lens is constituted by a radiation-side convex lens and an LED-side convex lens that are arranged in a direction of the optical axis. Between the LED and the projection lens, a light distribution member is placed that is formed using a transparent material and has, on its inner surface, a reflection face for reflecting light emitted by the LED.

Headlight for in-vehicle use

An exhaust gas purification device is provided. The device includes: in an exhaust gas passage for a combustion exhaust gas containing a nitrogen oxide, a hydrocarbon, and an oxygen in a larger amount than a theoretical reaction amount with respect to the hydrocarbon to flow therethrough, in order from upstream, a first catalyst part for selectively reducing a nitrogen oxide; a plasma discharge part for generating a plasma; a second catalyst part for selectively reducing a nitrogen oxide; and a purifying catalyst part for purifying a reducing agent.
