  • Patent number: 11966072
    Abstract: A planar light source device includes a plurality of light sources that is independently drivable, a first light guide to emit light incident from the first light source from an emitting surface in an emitting direction, a second light guide that is contained in a second light emitting region adjacent to a first light emitting region containing the first light guide and emits light incident from a second light source from the emitting surface in the emitting direction, and a partition frame having a partition wall that is positioned between the first light guide and the second light guide, partitions the first light emitting region and the second light emitting region, and is provided with a gap from the emitting surface of the first light guide, in which an angle formed by a wall surface and a bottom face of the partition wall is an acute angle.

  • Patent number: 8149320
    Abstract: A shooting optical system for performing flange back adjustment by moving a lens unit included in the shooting optical system in an optical axis direction includes: a drive gear engaging a lens holding frame for holding the lens unit; a drive unit for rotating the drive gear; a first gear rotating relatively to the drive gear; an operation unit for the flange back adjustment, for rotating the first gear; a detection unit for detecting a relative positional relationship between the first gear and the drive gear; and a control unit for driving the drive unit so as to rotate the drive gear based on a detection signal detected by the detection unit, thereby moving the lens holding frame in the optical axis direction so that the flange back adjustment is performed.

  • Patent number: 5500754
    Abstract: A two-way optical transmitter in which optical transmitters each having light projecting means and light receiving means on an optical axis intersecting the optical axis of the light projecting means are disposed in opposed relationship with each other with a predetermined distance interposed therebetween and which effects two-way optical transmission, wherein a polarizing beam splitter, having a cemented surface forming a certain angle with respect to the optical axes of the light projecting means and the light receiving means is installed near the point of intersection between the two optical axes, linearly polarized light from the light projecting means is reflected by the cemented surface of the polarizing beam splitter to thereby provide transmission light, and an optical axis leading from the polarizing beam splitter to the light projecting means or an optical axis leading from the polarizing beam splitter to the light receiving means is set at an angle of approximately 45.degree.

  • Patent number: 4663105
    Abstract: In producing a SiC base sintered material containing a small amount of B as a sintering assistant, a boron-containing organic compound obtained by reaction between a boron compound and an uncross-linked phenolic resin, either a resol or a novolac, is used instead of using an elemental boron powder. The starting boron compound is, e.g., H.sub.3 BO.sub.3, BCl.sub.3 or (C.sub.2 H.sub.5).sub.2 BOH. A mixture comprising 100 parts by weight of SiC powder and 2-10 parts by weight of the boron-containing organic compound is compacted or molded into a desired shape, and the shaped material is heated in a nonoxidizing atmosphere first at a relatively low temperature to accomplish thermal decomposition of the boron-containing compound and then at a sufficiently high temperature such as 1800.degree.-2200.degree. C. to accomplish sintering of SiC. By this method agglomeration of boron in the sintered material is prevented, so that sound sintering is achieved in every region of the shaped material.

  • Patent number: 3947943
    Abstract: A machine comprises a wire station for supplying various wires, a harness board on which a cable harness is to be formed, and a harness laying head movable relative to the harness board for receiving selected one of the wires from the wire station laying the selected wire on the harness board. The wire station comprises a plurality of wire clampers for releasably clamping the respective wires with their free ends protruding approximately a predetermined length towards the harness laying head.
