Abstract: A Fresnel lens includes a Fresnel lens body, grooves formed on the lens surface of the Fresnel lens body and having bottom surfaces and inclined surfaces and a light absorber formed over the inclined surfaces and the bottom surfaces in which a contact angle at an end portion of the light absorber with respect to the bottom surface is larger than 70 degrees is used. A method of forming a film of a lens includes coating inclined portions of a plurality of grooves formed on a lens surface with ink, fixing the ink and removing unnecessary portions of the ink by laser.

Abstract: A vehicle-mounted radar device has: a radar transmitting circuit transmitting a radar transmission waves to be reflected at a target; a radar receiving circuit receiving the reflected waves; a radar's axial deviation detecting circuit deciding whether the radar axis of the radar device has a deviation, according to the difference between a first value (distance between the vehicle and the known still object based on a shape of the known still object) and a second value (distance between them at a time when a radar reflected wave having attenuated power of the known still object among the radar reflected waves is received); and an axial deviation notifying circuit making a notification of the axial deviation.

Abstract: A printing unit includes a plurality of ink jet parts and an X-axis linear motion mechanism that moves each of the plurality of ink jet parts in the same main scanning direction. The X-axis linear motion mechanism moves the ink jet part involved in printing the workpiece among the plurality of ink jet parts so as to face the surface of the workpiece and moves the remaining ink jet part on the one X-axis linear motion mechanism so as to retreat from the surface of the workpiece. As a result, a printing apparatus that is capable of printing accurately onto the workpiece having a three-dimensional curved surface is provided.
