Title: Projection aligner
Inventor: SATO HIROSHI
IPC: G03F7/20
Filed: 1999-11-05
Abstract: PROBLEM TO BE SOLVED: To minimize variation of illuminance when illumination conditions are altered and to correct variation of illuminance inherent to each projection aligner. SOLUTION: Effect z of an optical filter 17 can be represented by z=a(x2+y2). When the optical filter 17 is moved two-dimensionally along a plane perpendicular to the optical axis, a variation of one-dimensionally inclining illuminance distribution can be generated. Illuminance at the meshed part on fig. 7 (C) is thereby measured previously and used as basic data. The ND filter 17 is moved by a specified distance d0 in the X direction and Y direction and variation of illuminance is measured, variation of illuminance is calculated at four points on the periphery of a plane to be irradiated and the effect of variation is stored when the ND filter 17 is moved. Moving direction and amount of the ND filter 17 are then calculated based on the effect.  Finally, the filter 17 is driven by a specified amount in a specified direction through an optical filter drive mechanism 18 based on the calculation results.

IPC: A61G7/047
Filed: 1993-12-17
Abstract: PURPOSE: To obtain a bed pad for water treatment applied to patient, by making it with a united multi layer cloth having hydrophobic and hydrophilic adjacent layers of cloth. CONSTITUTION: Body temperature pushes out water along the hydrophobic tissue of an outer cloth 16, then the water is pulled inside the integrated hydrophilic tissue of the inner cloth 17. Middle layer cloth 12 in face contact adjacently with the hydrophilic inner cloth 17 of an upper layer cloth 11 would receive the absorbed water from the upper layer cloth 11 composed of hydrophilic tissue and disperse it. The middle layer cloth 12 would keep almost all of the absorbed water contained, which would improve the ability of a bed pad 10 to keep its cloth surface to contact the patient comparatively dry. The lower layer cloth 13 is made liquid impermeable as well as vapor permeable, then it vaporizes the water in a vapor form concurrently representing a leakage protection layer of bed auxiliaries against the liquid.  Cloth layers are jointed together with spot juncture having intervals covering the whole surface of the bed pad 10, which can be washed on and be used again.
