  • Patent number: 6822799
    Abstract: An exposing apparatus for a microlens array allows for easy alignment and attains high accuracy. An exposing method for a microlens array attains high accuracy and high light efficiency. The exposing apparatus for a microlens array includes a micro fly-eye lens for converting a light beam from a light source into a secondary point light source, a transmittance distribution mask for adjusting the luminance of the light of the secondary point light source, and a collimator lens for converting the light of adjusted luminance into a parallel light beam and for guiding the parallel light beam, via a first microlens array which is formed in advance, to a photosensitive resin layer to be a second microlens array. The light emitted from the light source is transmitted through the micro fly-eye lens, the transmittance distribution mask, and the collimator lens. The light is then adjusted to a desired luminance to expose the photosensitive resin of a microlens substrate.

    Abstract: An object of the invention is to provide a method of manufacturing a microlens array and a projection-type liquid crystal display apparatus which can increase the efficiency of use of light, facilitate a method of manufacturing a microlens array and reduce the cost of equipment. By an operation of only irradiating a first lens with parallel light which has an intensity distribution corresponding to the shape of a second lens and irradiating an ultraviolet curing resin layer with transmission light, the first and second lenses are placed with a high alignment accuracy in a mutual positional relation thereof. By irradiating the first lens with the parallel light, it becomes possible to uniformly expose a broad area, and it becomes possible to expose by the wafer.

  • Patent number: 6642320
    Abstract: A multi-functional cement dispersant contains a graft copolymer obtained by a graft reaction of one or more selected from polyoxyalkylene monoalkylester, polyoxyalkylene monoalkylether and polypropyleneglycol of specified kinds to a copolymer obtained by radical polymerization of a mixture of radical polymerizable monomers containing maleic anhydride and monomers of a specified kind at a specified ratio. Hydraulic cement compositions produced with such a multi-functional cement dispersant have a superior fluidity with reduced loss over time and hardened objects produced from such a composition exhibit a superior early strength and have a low dry shrinkage and a high resistance against freezing and thawing.

  • Publication number: 20030128321
    Abstract: An optical device includes an optical path shifter that has at least one optical path shifting section. The optical path shifting section includes: a polarization modulator for changing the polarization state of an incoming light ray; and a birefringent element for shifting the optical path of an outgoing light ray of the polarization modulator based on the polarization state of the outgoing light ray. The optical device further includes a polarization corrector, which selectively changes the polarization state of an outgoing light ray of the optical path shifter, thereby keeping the polarization state of an outgoing light ray of the polarization corrector substantially unchanged no matter where the optical path has been shifted.

  • Publication number: 20030095092
    Abstract: An optical shifter includes at least one shifting section that periodically displaces the optical axis of incoming linearly polarized light. The shifting section includes first and second liquid crystal cells and a birefringent element. Each of the liquid crystal cells changes the polarization direction of the incoming light from a first direction into a second direction, or vice versa, responsive to a voltage being applied to the cell. The first and second directions are perpendicular to each other. The birefringent element changes its refractive indices with the polarization direction of the light incident thereon. The first and second cells and the birefringent element are arranged to transmit the incoming light in this order. The liquid crystal layer of the second cell compensates for a disturbance in polarization that was caused while the incoming linearly polarized light was transmitted through the liquid crystal layer of the first cell.
