Title: Photoreceptive member
Inventor: SAITOU KEISHI
IPC: G03G5/082
Filed: 1984-03-28
Abstract: PURPOSE:To make the titled member applicable to coherent light by forming a photoreceptive layer provided, successively from a base side, with the 1st layer consisting of a-SiGe and the 2nd layer consisting of photoconductive a-Si into specific layer structure and incorporating a conductivity governing material therein in a secifically distributed state. CONSTITUTION:The titled member has a photoreceptive layer 1000 made into the multi-layered structure provided, successively from a base 1001 side, with the 1st layer 1002 contg. a-SiGe and the 2nd layer 1003 contg. a-Si having photoconductivity. A material (C) which governs conductivity is incorporated into at least either of the layer 1002 and the layer 1003. The material C in the layer region contg. the material C is distributed nonuniformly in the layer thickness direction. The layer 1000 has >=1 pairs of non-parallel boundaries within the very small part and many of such non-parallel boundaries are arranged in at least one direction within the plane perpendicular to the layer thickness direction. The interference effect of irradiated light is prevented by increasing the number of the layers constituting the layer 1000 in the above-mentioned way. The interference fringes generated in the very small part do not apear on the image as the size of the very small part is smaller than the spot diameter of the irradiated light, i.e., said size is smaller than the resolution threshold. The generation of the interference fringes is thus prevented and the member is used for laser light, etc.

Filed: 1998-03-12
Abstract: PROBLEM TO BE SOLVED: To treat raw water containing iron, manganese, and organic substances stably and efficiently by a method in which the raw water, after being oxidized with air, is oxidized with ozone and subjected to membrane separation. SOLUTION: In the purification of water, raw water containing iron, manganese, and organic substances is exposed to air from an air diffusing pipe 2 in a raw water tank 1 to be oxidized with air. The most part of oxidation- vulnerable iron is oxidized by the aeration to be deposited. The air oxidized raw water is oxidized with ozone in an ozone column 3. The organic substances is oxidation-decomposed into low molecular weight compounds by the ozone oxidation, and the manganese is oxidized to be deposited as insoluble manganese dioxide. After that, water treated by ozone oxidation is passed through an active carbon column 4 for active carbon treatment, and the low molecular weight compounds are adsorbed/removed.  The treated water of the active carbon column 4 is subjected to membrane separation by an UF membrane separator for the solid-liquid separation of the insoluble substances of iron and manganese and other suspended substances.
