Title: Optical system for lsi manufacturing contraction projection aligner by light
Inventor: SHINOHARA YASUKO
IPC: G03F7/20
Filed: 1991-09-02
Abstract: PURPOSE:To obtain a mirror type stepper in which a short wavelength ultraviolet ray is used as a light source and which has a deep focal depth, a wide exposure area and a large numerical aperture. CONSTITUTION:A light source is mounted at one focal point of a rotational elliptical concave mirror, the small hole 8 of the mirror 7 is mounted at the other focal point, and the hole 8 also becomes a focal point of a parabolic mirror 10. A high coherent light is used as a light source thereby to deepen a focal depth, to remove various aberrations and to improve an effective numerical aperture. Further, a reticle image is increased larger than an image on a wafer and the width of the wavelength of an illumination light is increased thereby to prevent deterioration of the image due to the use of the coherent light. In this case, its resolution is improved when transparent liquid is filled between optical systems.

Title: Photocatalyst body, light source and lighting fixture
Inventor: WATANABE TSUTOMU
IPC: F21V3/04
Filed: 1996-12-09
Abstract: PROBLEM TO BE SOLVED: To increase transmittance for visible rays without decreasing the photocatalytic effect and to prevent production of interference colors by forming a photocatalyst film having higher transmittance for visible rays at a specified wavelength by a specified ratio than the transmittance for UV rays at a specified wavelength on at least a part of the surface of a base material which transmits light of a specified wavelength range. SOLUTION: The base body 2 consists of a glass plate which transmits at least light in <=410nm wavelength region. The photocatalyst film 3 is formed by applying titania alkoxide on the film forming face of the base body 2 by dip coating method, drying and baking at about 650 to 800 deg.C for about 30sec to 5min. The transmittance of the photocatalyst film 3 for visible rays at 550nm wavelength is higher by >=15% than the transmittance for UV rays at 365nm wavelength. Even when the back surface of the base body 2 is irradiated with light, the light is transmitted through the base body 2 to activate the photocatalyst film 3. The photocatalyst film 3 hardly absorbs visible rays and hardly produces interference colors.

Abstract: PURPOSE:To prevent the ionization of the foreign matter stuck by rubbing and the deterioration in the voltage holding rate of a liquid crystal in spite of long-time continuous driving by terminating plural pieces of scanning lines near a rubbing start point near picture elements. CONSTITUTION:The orientation of the liquid crystal is executed by printing an org. material of a polyimide system on the surfaces of an active substrate 1 and a counter electrode substrate 7 in contact with the liquid crystal to deposit this material in the form of thin films, then rubbing these thin films plural times with cloth in a specified direction. The scanning lines 2 on the rubbing start point side of the active substrate 1 and the counter electrode substrate 7 are made into the structure terminating at the switching element parts of picture element parts 9. The scanning lines are not disposed in the regions packed with the liquid crystal exclusive of the picture element parts 9 near the rubbing start point and, therefore, the foreign matter stuck by the rubbing are stuck to the inside of the picture element parts 9. The foreign matter stuck to the inside of the picture element parts 9 is, however, as small in size as a microscopic level and is, therefore, negligible for practicable use.
