  • Patent number: 5432587
    Abstract: A reticle (25) is displaceably supported in an optical axis relative to a reticle pattern image (33). When the reticle is displaced, a pattern image (35) has a negative longitudinal spherical aberration. The pattern image is clear on a photo resist layer on a wafer (37) that has a central surface and a side surface which is lower than the central surface. A first transparent parallel-plate may be removably placed between the reticle and the wafer. The first transparent parallel-plate gives a positive longitudinal spherical aberration of the pattern image. A second transparent parallel-plate may be movably placed between the reticle and the wafer. The second transparent parallel-plate gives a negative longitudinal spherical aberration to the pattern image.

  • Patent number: 5432636
    Abstract: In a rear-projection screen comprising a Fresnel lens and a light-diffusing member such as a lenticular lens sheet, a rise angle in a central region of the Fresnel lens is smaller than a rise angle in an intermediate region thereof (e.g., the former is not larger than 3.degree. and the latter is larger than 3.degree. ). The rise angles may preferably gradually increase from the central region of the Fresnel lens toward the intermediate region thereof. The central region of the Fresnel lens may preferably be a region extending within the range of from 1/4 to 1/3 from the middle point of a diagonal of the rear-projection screen. Such a Fresnel lens is effective for improving white uniformity in the intermediate region of the rear-projection screen and eliminating color corn in the central region thereof.

  • Patent number: 5424804
    Abstract: A method and apparatus for establishing optimum film exposure time for documents of different reflectances, A photo-sensor is used to produce a signal proportional to the intensity of light reflected from the document to be microfilmed, The signal is integrated and a time is determined for the integrated signal to reach a threshold or reference value, The time needed to reach the threshold value is measured very accurately by a microprocessor, The measured time is then convened to new time by using a look-up table, The new or desired shutter time is controlled by the microprocessor by terminating the exposure when the total time the shutter was open equals new exposure time found in this look-up table.
