摘要： The illuminating apparatus of the present invention has two light conductive bars which have one spot-like light source in common on their end surfaces, and which are disposed with their respective side surfaces facing each other and along the end surface of a light conductive plate. The spot-like light source has the center of its light emitting surface positioned to an interface portion between the two light conductive bars, whereby non-uniformity in brightness of lights at the end surfaces of the light conductive bars is diminished at the end surface of the light conductive plate with respect to the length direction of the light conductive bars while the lights emitted from the spot-like light source and introduced into the light conductive bars have their optical paths changed at respective optical path conversion means formed on the light conductive bars, and travel into the light conductive plate.

摘要： A light conductive bar has a plurality of flat portions parallel to a side surface thereof facing a light conductive plate and formed on a side surface thereof opposite to the side surface and a plurality of inclined surfaces descending from one end surface facing a spot-like light source toward the other end surface, wherein the flat portions step down gradually from the one end surface to the other end surface. When light introduced into the light conductive bar from the one end surface is repeatedly reflected at the flat portions and the side surface facing the light conductive plate, angles of reflections thereat can stay larger than the critical angle because the flat portions are parallel to the side surface. Accordingly, the light can travel to the other end surface without leakage, thereby improving the luminance of the apparatus.

摘要： A spread illuminating apparatus provides a uniform illuminance, an accurate illumination, an improved visibility, and an expanded screen size. Light sources (5a, 5b) comprising bar-like light conductive members (3a, 3b) and spot-like light sources (4a, 4b), respectively, are disposed close to end surfaces (8a, 8b) of a transparent substrate (2). A light reflection pattern (29) is formed on a surface of the transparent substrate (2) along the length of the light conductive members (3a, 3b). The light reflection pattern (29) comprises grooves (27) and flat portions (28) adjacent to the grooves. The grooves (27) are shaped trapezoidal in section, and the depth thereof increases in proportion to the increase in distance from the light sources (5a, 5b) and measures maximum at the center of the transparent substrate (2).

摘要： The invention describes a light reflection pattern to spread the volume of the emitted light from a bar-like light source with a plurality of grooves provided along a transparent substrate and plane portions adjacent to the grooves. By setting the inclined angle of the grooves along the transparent substrate the light is introduced with a high efficiency to a liquid crystal display device in the direction perpendicular to the substrate. By restricting the ratio of the width of the grooves to the pitch that is the occupied area in the range of 0.01-0.15 (preferably 0.01-0.1) the ratio becomes one in which the duplicate image component is not recognized by the naked eyes while image brightness is maintained.

摘要： A plug for an optical fiber cable comprises a plug proper having a line-inserting portion for insertion of an optical fiber and a primary covering layer in a state communicating with the interior, an optical fiber-inserting portion for inserting only the optical fiber, a cylindrical portion formed on the outer wall of the line-inserting portion to caulk and fix the line, and a pressing portion having a concave-convex part formed to anchor the filamentary reinforcing fiber exposed from the end of the optical fiber cable onto the periphery of the pressing portion, and at least one ferrule for caulking the filamentary reinforcing fiber exposed from the end of the optical fiber cable to the concave-convex part of the pressing portion of the plug proper, and further, caulking the secondary covering layer. By adopting the above-mentioned structure, an optical fiber cable plug is obtained in which the primary covering material is caulked and secured, and therefore, problems such as a turning and protrusion of the line of the optical fiber do not arise.

摘要： In apparatus for following sun light, at least two pairs of diametrically facing light-receiving elements (30a, 30c and 30b, 30d) are provided along the periphery of a circular end plane of incidence (24) of an optical fiber cable (20) where sun light is condensed by way of a lens 14. The deviation of a condensed light area from the circular end plane of incidence (24) will be effectively detected by the light-receiving elements to control a drive unit (46) which drives an equatorial (18) carrying an optical system including the lens (14) and the end plane of incidence (24) of the optical fiber cable (20). In one embodiment, another light-receiving element (50i) is provided at the center of the end plane of incidence (24) to detect when light condensing area is deviated to a great extent. The output signal of this light-receiving element (50i) is used to perform speed control of the drive unit (46). In another embodiment, a circuit arrangement for detecting abnormal state of the optical system is also used.
