  • Patent number: 10928597
    Abstract: A light emitting module including a semiconductor light emitting element, a first lens, a second lens, and an optical fiber stub, is disclosed. The first lens collimates light output from the semiconductor light emitting element. The second lens is a meniscus lens and condenses the collimated light to the optical fiber stub. A light entering surface of the second lens has a cross-sectional shape in which an increase rate of a curvature radius is zero or more. A light exiting surface of the second lens includes a first region and a second region. The first region has a cross-sectional shape in which a sign of the increase rate of the curvature radius is positive. The second region surrounds the first region and has a cross-sectional shape in which a sign of the increase rate of the curvature radius is negative.

  • Patent number: 5998917
    Abstract: A flat picture tube including a glass vessel which is internally evacuated, a heater installed inside the glass vessel for emitting heat electrons, a plurality of anodes extended in one direction and disposed at a constant interval on one inner plane of the glass vessel for absorbing the heat electrons, a plurality of fluorescent units disposed on the plurality of anodes in a matrix shape for radiating depending on heat electrons absorbed to the anodes, and a plurality of control grids extended perpendicularly to the anode extended direction and disposed in a constant interval for controlling the absorption of the heat electrons toward the anodes operates in a matrix digital method and does not necessitate an electron gun nor deflection yokes, thereby reducing the volume thereof. In the case of a 20 inch picture tube, the maximum thickness thereof is only 5 cm so that it can be adopted for a wall television. Also, since a high-voltage power is not required, the overall power consumption is lowered.

  • Patent number: 5218264
    Abstract: An image pick-up apparatus is disclosed which includes a target portion having a photoconductive film on a substrate and a target electrode and reads video information converted into an electric signal in the photoconductive film by an electron beam. An insulating region is provided for the target portion such that carrier generated in an ineffective scanned region (a target region corresponding to an area not scanned by the electron beam) does not appear on a surface of the target portion.

  • Patent number: 5029963
    Abstract: An image intensifier retrofit system for a Generation II based driver's viewer assembly, identified as AN/VVS-2. The system includes a housing which is dimensionally the same as the Generation II tube housing. Positioned at one end of the housing is a Generation III image intensifier tube and at the other end of the housing is a fiber optic element. Positioned between the tube and the fiber optic element is a relay lens assembly. The Generation III tube receives the light from a viewed scene from an objective lens assembly of the dirver's viewer. The intensified image output from the tube is received by the relay lens system which inverts and magnifies the image and transfers the image to the input surface of the fiber optic element. The fiber optic element in turn transfers the image to its output surface from which surface the image is viewed by the user of the driver's viewer through a biocular eyepiece.
