  • Patent number: 10951868
    Abstract: In an MEMS projector (10), an image signal processing unit (110) outputs an inspection signal, and an inspection signal processing unit (114) outputs a light emission instruction signal. An inspection light source drive unit (112) outputs a light emission signal, and an inspection light source (13) radiates an inspection light. The inspection light radiated from the inspection light source (13) is reflected at the reflection position RP of a first support portion (22), and then received by a light receiver (14). Then, the light receiver (14) outputs a received light signal. Based on the received light signal, the inspection signal processing unit (114) detects the angle of the light deflecting mirror (20) around the X axial line.

  • Publication number: 20020041344
    Abstract: A method and an apparatus for reducing radiation of a cathode-ray tube display are provided. According to the invention, the voltage signals of the two terminals of the horizontal deflection yoke are pulses of equal amplitude but opposite polarity. Thus, at positions which is equally apart from the two terminals of the horizontal deflection yoke, the electromagnetic radiation generated from the two terminals during operation of the cathode-ray tube can be substantially cancelled. Thus, the influence of the electromagnetic radiation from the horizontal deflection yoke on a user sits in front of the cathode-ray tube display is effectively reduced to a minimum. Further, it is only required to modify the way of winding in the flyback transformer and the cathode-ray tube remains unchanged. In this way, it requires almost no additional power dissipation for the reduction of the undesired electromagnetic radiation. Therefore, the electromagnetic radiation reduction is achieved and the cost is lowered.

  • Patent number: 6323592
    Abstract: Disclosed is a conductive antireflection film comprising a laminate structure consisting of a conductive layer and an insulating covering layer covering the surface of the conductive layer and a conductive member connected at one end to the conductive layer and exposed at the other end to the outside. The conductive member is brought into contact with an electrolytic solution so as to control the state of the metal contained in the conductive layer, making it possible to prevent effectively an electromagnetic wave from leaking to the outside and to obtain a clear image of a high contrast.

  • Patent number: 6229085
    Abstract: A filter 2A(2C), which prevents the leakage of electromagnetic waves from a PDP 1, is provided with a filter base 11 in front of the PDP 1 and a grounded conductive mesh 12 which transmits light from the base 11 on the PDP 1 side. A light scattering layer 13 is bonded to the mesh 12 by a conductive adhesive 14 which transmits light, and the spaces of the lattice, when the base 1 exists, of the mesh 12 are filled with the adhesive 14 so that, when an electric charge is induced in the mesh 12 by a pulse voltage applied to the PDP 1 for write/erase, the voltage across the lattice of the mesh 12 is made nearly equal to the potential of the mesh 12 so as not to cause an electric discharge and generate noise.

  • Patent number: 6195135
    Abstract: A substantially flat television display comprises, in accordance with the present invention, a plurality of superluminescent or laser diodes which are mounted to a substrate or carrier for spacing in a planar array. A protective sheet covers the diodes and is connected to the substrate or carrier, while energization componentry is operatively connected to the diodes for energizing the diodes in accordance with an incoming video signal to reproduce an image embodied in the video signal. In a color television or video display, the superluminescent or laser diodes are tuned to different frequency ranges, so as to reproduce the image in color.

  • Patent number: 5965974
    Abstract: A heat-shrink band for a cathode ray tube (CRT) has a light weight, corrects the deformation of an object, such as a panel of a CRT due to the air pressure, effectively prevents implosion of the CRT, can suppress the color deviation, and in addition is excellent in formability. The method of fabricating the heat-shrink band includes a composition of cold rolled steel sheet such that the heat-shrink band offers both a high elongation characteristic at an ambient temperature and a high stress of yielding point characteristic after the heat-shrink process. The reduction of the weight of the heat-shrink band contributes to an overall reduction of the weight of the CRT.
