    摘要: A ribbon supply shaft drive motor (8) and a ribbon take-up shaft drive motor (10) are drivingly controlled separately. If the state of a ribbon is not changed after a control cycle is repeated for a set time, the rotational speed of the drive motors (8, 10) is increased step by step.

    摘要: The invention provides a method for improving the contrast ratio of the display image projected on a screen from a liquid crystal projector that comprises at least a light source, an electrode-having, twisted nematic liquid crystal cell comprising at least one nematic liquid crystal, and two polarizers disposed so that the liquid crystal cell is sandwiched between them, which is characterized in that at least two HBLC optical films are so arrayed between the polarizers that the slow axes of the films are approximately perpendicular to each other so as not to cause a retardation in the direction normal to the film surfaces; and provides a liquid crystal projector that uses the improving method.

    摘要: A tubing including an overlap portion formed by the first and second circumferential end portions overlapping and joined with each other, and a fluid leakage preventing member for preventing pressurized fluid from leaking from the tubing upon the tubing being subjected to hydrostatic forming. An apparatus and method for hydrostatic forming of a tubing having an overlap portion. The apparatus includes a die and a nozzle having fluid leakage preventing means for preventing the pressurized fluid supplied into the tubing from leaking from a clearance between the first and second circumferential end portions of the overlap portion of the tubing at the longitudinal end portions of the tubing.

    摘要: A viewfinder display apparatus which can realize superimpose having good visibility without giving uncomfortable feeling to a photographer is disclosed. The viewfinder display apparatus includes an eyepiece lens unit, an a member on which illumination unit which irradiates illumination light, and a plurality of region display sections arranged in a viewfinder optical path respectively to correspond to the focus detection regions. Each of the region display sections includes an outer frame which partially transmits light from an object to display edges of the focus detection regions in the viewfinder field and reflecting region in which reflecting surface which reflects illumination light from the illumination unit to guide the reflected light to the eyepiece lens unit are formed.
