Abstract: PURPOSE:To eliminate a possibility of dissolving a surface diffusion sheet and rear surface reflection sheet and to enable easy production of intricate adhesive patterns as well so as to shorten stages by printing sheets to be stuck to a light transmission plate with tacky adhesives and sticking these sheets to the light transmission plate. CONSTITUTION:A ray source 7 is arranged on the flank of the light transmission plate 1. The front surface diffusion sheet 3 is arranged on the front side of the light transmission plate 1 and the rear surface reflection sheet 4 is arranged on the rear surface of the light transmission plate 1. A flank reflection sheet 5 is formed on the other flank of the light transmission plate 1 facing the ray source 7. These sheets 3 to 5 are first printed with the tacky adhesives 6 in order to fix the sheets 3 to 5 to the light transmission plate 1 by the tacky adhesives 6. A separator is then stuck to the light transmission plate and outside shape blanking is executed. The outside shape blanking is executed to process the sheets 3 to 5 to the same size as the size of the light transmission plate 1 by a method, such as pressing. Finally, the separator is peeled and the sheets 3 to 5 are stuck to the light transmission plate 1.

Abstract: PURPOSE:To obtain the light transmission plate for a panel light emission device with which panel light emission of high brightness is obtainable. CONSTITUTION:A polyethylene terephthalate film, the surface of which is subjected to sand blasting, is used as a base body sheet 2. A radiation curing resin consisting of polyester acrylate contg. calcium carbonate as light diffusible pigment and pentaerythritol acrylate is applied over the entire surface of this sheet by a gravure coater method. The radiation curing resin is crosslinked and shrunk by irradiation with electron beams to form a light diffusion layer 3 having ruggedness on the surface. An adhesive layer 4 consisting of an acrylic resin is formed as gradation patterns on this light diffusion layer 3 by a screen printing method to form a transfer material. Such transfer material is used and is transferred onto the rear surface of a transparent photoconductor 1 consisting of an acrylic resin and thereafter, the base body sheet 2 is peeled, by which the light transmission plate for the panel light emitting device is obtd.

Abstract: PURPOSE:To obtain a patterned light diffusion sheet which is easily changed in optical characteristics and has the pattern having high accuracy and high resolution by controlling the pigment and resin ratios of a matting agent and the thickness of a matte layer and patterning transparent parts and non- transparent parts by a photomechanical process. CONSTITUTION:The matte layer 2 is formed of the matting agent contg. the pigment having a light diffusing effect is formed on a film 1 on which the transparent parts 3 and the non-transparent parts 3 are formed by the photomechanical process. The light from a light source disposed on the rear face of the light diffusion sheet is, therefore, passed through the transparent parts 3 of the film and is uniformly diffused by the matte layer 2 so that the pattern formed by the transparent parts 3 and the non-transparent parts 4 can be evenly illuminated to the uniform brightness. The desired optical characteristics are obtd. by adjusting the compsn. of the matting agent and the thickness of the matte layer 2 at this time. The patterns are formed by the photochemical process. The optical characteristics are thereby easily changed and the patterns having the high accuracy and high resolution are obtd.

Abstract: PURPOSE:To execute an almost uniform surface light emission by constituting the titled plate so that light beams having a high luminance among light beams from a light source transmits through a part where an occupied rate of a printing film per unit area is large, of a light transmissive plate, and on other hand, light beams having a low luminance transmit through a part where occupied area rate is small. CONSTITUTION:In a part where light beams having a high luminance transmit through, of a transparent plate 1, an occupied area rate of a printing film 2 is large a gap through which the light beams transmit through is small, therefore, the transmissivity of light beams from a light emission diode 4 is deteriorated, and a luminance of a transmission light beam drops. On the other hand, in a part where light beams having a low luminance transmit through, of the transparent plate 1, the occupied area rate of the printing film 2 is small and the gap through which the light beams transmit is large, therefore, the transmissivity of the light beams from the light emission diode 4 is good, and the light beams from the light emission diode 4 hold its luminance roughly as it is and transmit through, and also, reflected light beams which have been reflected by a reflecting plate 3 transmit through the part corresponding to the peripheral part of the light emission diode 4 of the transparent plate 1. In this way, an almost uniform surface light emission can be executed extending over a wide range to not only the part opposed to the light source but also the part corresponding to the peripheral part of the light source.

Abstract: PURPOSE:To simultaneously regenerate a used silver halide photographic developer and a used silver halide photographic bleaching bath with high efficiency by pouring the developer into the cathode side of an electrolytic cell partitioned by a monovalent anion exchange membrane and the bath into the anode side followed by electrolysis. CONSTITUTION:Cathode chamber 4 of electrolytic cell 1 in which rodlike or platelike graphite cathode 2 and rodlike or platelike graphite anode 3 are separated by one or more monovalent anion exchange membranes 6 is filled with a used silver halide photographic developer, and anode chamber 5 with a used silver halide photographic bleaching bath. By supplying an electric current, hydrogen is generated on cathode 2 to reduce oxides such as an oxidized developing agent contained in the developer by the reducing power, and a reduced oxidizing agent in the bath is oxidized on anode 3. Excess bromine ions present in large quantities in chamber 4 are shifted to chamber 5. The used developer and the sude bath are regenerated simultaneously through the above-mentioned reaction processes.

Abstract: PROBLEM TO BE SOLVED: To provide an EMI shielding material which is provided at a low cost, superior in productivity, and capable of keeping a display image plane highly visible. SOLUTION: This EMI shielding material is provided with a conductor that forms a grounding part and a shielding part and an adhesive layer are high in adhesion to each other by a method, wherein an adhesive layer 2 is provided to the entire surface of a transparent base material 1, a metal foil layer 3 provided with a frame-like grounding part and one of a shielding part of lattice, stripe, or honeycomb pattern surrounded with the grounding part is provided to the adhesive layer 2, and a transparent overcoat layer 4 is formed so as to cover the exposed part of the adhesive layer 2. Such an EMI shielding material is planarized by covering the rugged exposed surface of an adhesive layer 2 with a transparent overcoat layer 4, so that the light rays emitted from the display image plane are restrained from being scattered or reflected at a part, where a metal foil layer is not provided even if the EMI shielding material is arranged on a display screen making its transparent base material face toward the display screen, the EMI shielding material is improved in light transmission in the front direction, and a superior visibility is obtained.
