  • Patent number: 5978627
    Abstract: A method and system for measuring sensitivity of an electrophotography photoconductor. The sensitivity is determined using changing information of the surface potential of the photoconductor and an exposure amount information which is precisely obtained by measuring relative illuminance on the surface of the photoconductor with a photo-sensor disposed between a shutter performing ON/OFF operations of light and the photoconductor while the photoconductor is exposed to light. Then, a changing curve of digitized measured relative illuminance is integrated from a rising point thereof to a point thereof at a time when the surface potential information becomes a specified value.

  • Patent number: 5300966
    Abstract: An original image is divided into a plurality of image parts in the forms of image signals which are then given to liquid crystal light valves, respectively so that liquid crystal light valves display the plurality of image parts therein. These liquid crystal light valves allow light from light sources to pass through so as to form image light beams which are intensity-modulated in accordance with the divided image parts. A plurality of mirrors reflect the image light beams and introduce them onto a projecting lens system. In this arrangement, the plurality of mirrors are located in such a way that their reflecting surfaces do not cross the optical axis of the projecting lens system, and the image light beams are synthesized on the screen so as to reproduce an original image. Accordingly, the pixel density of the original image can be multiplied by a multiplier which equal to the number of used liquid crystal light valves.
