  • Patent number: 11142019
    Abstract: A method for manufacturing a decorated-part comprises a first and second base coat-layer-forming process, a surface coat-layer-forming process and a laser-decorating process. In the first base coat-layer-forming process, the first base coat-layer colored in a highly light color at a lightness-level of 70 or more is formed on the surface of the resin base-material 12. In the second base coat-layer-forming process, the second base coat-layer 21C colored in a chromatic color is formed on the first base coat-layer. In the surface coat-layer-forming process, the surface coat-layer colored in a less-bright color at a lightness-level of 20 or less is formed on the second base coat-layer 21C. In the laser-decorating process, the first laser-processed groove penetrating the surface coat-layer and exposing partially the second base coat-layer is made by irradiating the infrared laser onto such surface coat-layer, thus providing a fine decoration onto the surface of said decorated-part.

  • Patent number: 5268781
    Abstract: A homeotropic-alignment liquid crystal display device having a high photostability and a high contrast ratio and a method of producing the same are disclosed, wherein while two glass substrates having patterned transparent electrodes are set obliquely at a first angle with respect to an evaporation source, then a first SiO.sub.2 film is deposited on each of the glass substrates while irradiating the glass substrates with an ion beam emitted from an ion gun. Subsequently, the glass substrates are turned in their planes over an angle of 90 degrees and set obliquely at a second angle with respect to the evaporation source, and thereafter, a second SiO.sub.2 film is deposited on the respective first SiO.sub.2 films while irradiating the first SiO.sub.2 film with the ion beam. The first and second SiO.sub.2 films thus deposited on the glass substrates jointly form homeotropic-alignment undercoat films.

  • Patent number: 5200283
    Abstract: An information recording medium includes a first transparent electrode, and a carrier transport layer formed on the first transparent electrode for generating an electric current on the basis of fed carriers. A carrier generation layer formed on the carrier transport layer serves to generate carriers corresponding to a distribution of an intensity of incident information-writing light containing information, and serves to feed the generated carriers to the carrier transport layer. An electric power supply electrically connected to the first transparent electrode serves to generate an electric field corresponding to the distribution of the intensity of the incident information-writing light in cooperation with the carrier transport layer and the carrier generation layer.

  • Patent number: 5087929
    Abstract: A method of electrophotographic printing is disclosed. A recording medium comprising a photoconductive member and photo-modulation member laminated to each other, both exhibiting a photoelectric effect and a sensitized member made of a chargeable photoconductive member are arranged so as to face each other. A first electro-magnetic radiation beam (abbreviated in a beam hereinafter) which is intensity-modulated with data to be recorded is radiated to the recording medium at the photoconductive member side thereof to record the data to the photo-modulation member with the photoelectric effect. A second beam of constant intensity is radiated to the recording medium to emit therefrom a third beam exhibiting intensity variation subjected to the recorded data. The sensitized member is exposed with the third beam to form thereon a charge image corresponding to the recorded data. Toner is stacked onto the sensitized member formed with the charge image to form thereon a toner image.
