  • Fluorescent display device having an outer light source and light shielding film
    Patent number: 8648521
    Abstract: A fluorescent display device is disclosed. The fluorescent display device includes an anode plate, aluminum anode wirings arranged on the anode plate, a first light shielding aluminum film arranged on the anode plate, an insulation layer arranged on both the anode wiring and the first light shielding film, a second light shielding graphite film arranged on the insulation layer, an anode electrode arranged on the insulation layer, and an outer light source display formed by removing a portion of the first light shielding film. The outer light source display is illuminated by a LED to display a predetermined pattern. The second light shielding film is formed along a wiring array arranged on the first light shielding film and the wiring so that a gap between the first light shielding film and the wirings is covered with the second light shielding film.

  • Optical waveguide modulator having a reduced D.C. drift
    Patent number: 5526448
    Abstract: An optical waveguide device usable as an optical wave-modulator and having a reduced DC drift includes a LiNbO.sub.3 substrate, an optical waveguide formed in a front surface portion of the substrate, a dielectric layer covering the front surface of the substrate and the optical waveguide surface, and an electrode system arranged on the dielectric layer, the dielectric layer comprising a matrix component consisting of an amorphous SiO.sub.2 and a doping element component consisting of Li and/or Nb; and having a refractive index lower than that of the amorphous SiO.sub.2 matrix free from the doping element component.
