Abstract: A vehicular lamp includes a lamp outer case formed by a cover and a lamp housing; a light source disposed inside the lamp outer case; and a light guide that guides light emitted from the light source, wherein the light guide is shaped as a column. The light guide includes a first extension portion that extends on a horizontal plane side, and a second extension portion that extends on a vertical plane side with respect to a reference line that extends in a direction inclined 45 degrees with respect to the horizontal plane. An outer surface of the light guide includes an incident surface to which light emitted from the light source is incident, an internal reflection surface that internally reflects light incident from the incident surface, and a radiation surface that is formed as an outward-convexly curved surface and radiates at least light reflected by the internal reflection surface.

Abstract: An optical element comprises a pair of substrates each having an electrode and bonded together with a gap therebetween and a light adjusting material including a liquid crystal and enclosed in the gap. Each of the pair of substrates has an electrode connecting portion to be connected to an external circuit. At least a part of the electrode connecting portion of each of the substrates is located on the same side as that of the optical element. The electrode connecting portion of one of the substrates and the electrode connecting portion of the other of the substrates have respective electrode portions at regions that are not opposed to each other. The electrode portion of each of the electrode connecting portions is connected to the external circuit.

Abstract: A crushing apparatus is provided for crushing a printed circuit board on which electronic components are mounted into pieces of a size ranging from a few to ten centimeters square and separating some of the components and sheathed wires from the printed circuit board. The crushing apparatus comprises a rotor 3 having a substantially conical or truncated conical projected center 6 mounted at the center of rotation thereof, a plurality of extensions 3a thereof extending from the conical projected center 6 radially and horizontally, and studs 3 and 4 mounted on the extensions 3a thereof. A drive motor 8 is provided for rotating the rotor 3, a cylindrical case 1 accommodates the rotor 3 therein, and a plurality of studs 2 mounted are on the inner side of the cylindrical case 1.

Abstract: A light emitting reference point is set for a light source attached to a reflecting mirror having an opening on one end thereof, and it is assumed that a point light source is set on the reference point. Then, a reference surface formed as a set of half lines extending from the reference point to an arbitrary point on a front end edge of a socket arranged so as to interrupt rays of light from the point light source. Then, a partial surface of the basic surface of a reflective surface around the socket is arranged so that the partial surface projects more frontward than the reference surface, and a curved form of the partial surface is arranged so that the rays of light emitted from the point reach everywhere on the surface. Then, a group of paraboloids of revolution formed by a number of paraboloids of revolution whose focal distances are different from one another, is prepared, and intersecting lines between the basic surface and the group of paraboloids of revolution are obtained.
