    摘要： A polymer dispersed liquid crystal optical device is presented which has optical elements which control reflection, transmission and diffraction of incident light entering the device by adjusting the magnitude of the electrical field applied to the device between a maximum and a minimum limits. An optical element consists of a polymer material having an electrical field-independent refractive index, and a liquid crystal material having an electrical field-dependent refractive index. The optical elements are distributed through the device at specific inter-element spacings, thus enabling to generate reflection of incident light in accordance with Bragg's law of reflection. The inter-element spacings can also be varied by the application of the field, thus enabling to generate reflection of light of a desired wavelength. Such optical elements are ideal for use in full color optical display apparatus of a matrix driven type. Methods for producing the optical device and optical display apparatus are also presented.

    摘要： An electrophotographic process of this invention is achieved by subjecting a photosensitive screen to a matched performance of voltage applications and image irradiation to form a primary electrostatic latent image for modulating the flow of corona ions to enable a secondary electrostatic latent image on a recording member disposed in close proximity to the screen bearing the primary electrostatic latent image. The screen is made of a conductive member as the basic element for the screen, a photoconductive member covering the substantial part of the conductive member, and a surface insulating member also covering the substantial part of the conductive member and the photoconductive member, in which the conductive member is partly exposed at one surface side of the screen, or it is entirely covered by the surface insulating member with another conductive member to be exposed being provided on said insulating member, and the coating thicknesses of the photoconductive and surface insulating members are thicker at the portion opposite to the surface part of the conductive member to be exposed.
