    摘要: Liquid crystal for a right eye and liquid crystal for a left eye are not positioned in one plane, but are positioned to incline at an angle of 5°. To be concrete, both liquid crystal are inclined so that they become closer to the viewer's face as making toward the side of the face from the middle of the forehead. The inclination of liquid crystal as above-described to set the preferential direction of visual view of liquid crystal to be horizontal leads in that the direction by which the high contrast of liquid crystal can be obtained is toward the 3D display. It diminishes a phenomenon like cross-talk and allows the viewer to view the appropriate stereoscopic image. Liquid crystal for a right eye and liquid crystal for a left eye have the same construction. These liquid crystals make contrast with each other and then they are mounted on the liquid crystal shutter glasses portion. This makes it possible for each electrode to position in the center of liquid crystal shutter glasses portion. The construction in which the electric circuit is in the center of the liquid crystal shutter glasses portion makes it easy to make electric contact between the circuit and the electrode.

    摘要: A flat CRT having a phosphor screen inclined with respect to the center axis of an electron beam and formed by applying phosphors to the inner surface of a tube wall. The tube inner surface is defined by rotating a plurality of logarithmic spiral curves having a constant angle of incidence and present in the x-y plane of a polar coordinate system in which the deflection center of the electron beam is its origin, the center axis extends through the origin and serves as the x-axis, and the y-axis extends through the origin and intersects the x-axis at right angles therewith. The spiral curves are rotated about the y-axis each through a specified angle to obtain a group of logarithmic curves defining the tube inner surface.

    摘要: An automatic record feeding device particularly advantageous for use in association with a flexible foil-type video disc record used by a video disc player. The record feeding device includes a transfer roll having at least one escapement recess or notch formed in the outer peripheral surface thereof, and a back-up guide cooperative with the transfer roll to hold the disc record between it and the transfer roll during transfer of the disc record from one position to another.
