    摘要： A grating light valve is provided with a plurality of spaced reflective ribbons, spatially arranged over a semiconductor substrate, the ribbons and substrate being provided with reflective surfaces. The grating light valve is configured to optimize the conditions for constructive and destructive interference with an incident light source having a given wavelength. In a preferred embodiment, one set of ribbons is moveable with respect to the substrate and the second set of ribbons. The substrate is typically provided with a protective layer, which may be thermally grown silicon dioxide or other dielectric. A conductive trace is provided on the dielectric layer and grounded through the dielectric layer to the substrate, comprising a conductive trace for easy release of charge otherwise trapped on or at the dielectric layer.

    摘要： A photo film cassette has a spool core about which photo film is wound in a form of a roll. A cassette shell contains the spool core in a rotatable manner. Two flanges have a disk shape, and are secured to respective ends of the spool core, for regulating lateral edges of the roll of the photo film. A circumferential lip is disposed on each flange, is extended toward the opposite one of the flanges, wraps one of the lateral edges of an outermost turn of the photo film of the roll, and prevents the photo film from being loosened. A rim portion is disposed on an circular edge of the circumferential lip confronted with the opposite one of the flanges, to project with a bend away from the spool core. A contact face is disposed on the rim portion, and contacts the one of the lateral edges of the photo film when the photo film is unwound from the spool core or wound back about the spool core. The contact face has a contact range of 0.15-0.8 mm in contacting the one of the lateral edges of the photo film. At least one support projection projects from an axially outer face of said flange.

    摘要： A liquid crystal display of improved contrast is provided. Image contrast is determined by the ratio of light from the display pixels that are in an on state to the light from the display pixels that are in an off state. The disclosed system improves on the image contrast by selecting the illumination direction and the panel orientation in such a way as to minimize the amount of light entering the viewing field that is due to scattered and/or diffracted light from the fine features of the display panel.
