摘要： PURPOSE:To provide an antireflection coating whose refractive index increases in steps from the outermost surface to a transparent base and an antireflection film. CONSTITUTION:A layer of ultramicro powders is formed directly or via an intermediate layer over a transparent base film. The layer of ultramicro powders may be formed either by application of a dispersion liquid of ultramicro powders not containing binder resin or by application of a dispersion liquid of ultramicro powders containing a binder resin whose surface tension is weak enough so that the surface of ultramicro powders is exposed. The coating obtained completely exposes the ultramicro powders with no film of binder resin on their surface, thereby forming an uneven outermost layer in which air and the ultramicro powders intermingle. When the binder resin is used the antireflection coating comprises an air layer 1 contacted with the coating, an ultramicro powder/air layer 2 forming the outermost layer of the coating, a layer 3 of ultramicro powders, and a lowermost ultramicro powder/binder layer 4, with the refractive index of the coating increasing in a stepwise gradient from the surface to the base. Therefore, reflection of light can be prevented effectively.

摘要： PURPOSE:To cut down the cost by reducing the removed part of a thick film forming material. CONSTITUTION:After the formation of a pattern of a thick film forming material in a slightly larger size than a specific pattern shape on a substrate 1, any needless part is removed by subtracting step through the intermediary of a subtracting mark 3 in a specific pattern shape. Through these procedures, the title thick film pattern in an objective pattern shape can be formed by removing the thick film forming material slightly extending out of the subtracting mark 3 so that the applicable thick film forming material may suffice for less amount than the case when the whole substrate is coated with the material thereby enabling the removing time of the needless part to be cut down.

摘要： PURPOSE:To enlarge a selecting range of mask materials for sand-blasting, adapted to be used for forming a thick film pattern on a substrate by sand- blasting. CONSTITUTION:After a peel-off layer 3 is formed on a pattern forming layer 2 on a substrate, a mask layer 4a having a desired shape and made of a mask material having a sand-blast resistance is formed on the peel-off layer 3. After sand-blasting is carried out through the mask layer 4a, the mask layer 4a is removed from the peel-off layer 3 so as to provide a desired thick film pattern. After the sand-blasting, the masking layer 4a can be easily peeled off from the peel-off layer 3, and accordingly, a mask material which cannot be easily peeled off if it is directly applied over the pattern forming layer 2, can be also used.

摘要： PURPOSE:To repair a breakage portion in a short time as the dimensional accuracy of an electrode pattern is maintained by applying electrode paste to the breakage portion, and firing the breakage portion locally by means of laser without firing the whole board. CONSTITUTION:In repairing a breakage portion 3, the same stuff as an electrode paste is used as a repairing paste 4, and the repairing paste 4 is applied so as to fill up the breakage portion 3, and is dried in an oven. YAG laser with optimized energy density, spot diameter, processing time is radiated to an irradiation area 5 covering the repairing paste 4 so as to burn up organic component in the repairing paste 4. The laser radiation of CW oscillation is generated, is transmitted through optical fiber, and is radiated to the repairing paste 4. This irradiation conditions are for instance as follows, lamp current is 25-30 A, a beam diameter is 0.1-5mm, an irradiation time is 0.1-6 seconds. Thereby it is possible to repair the breakage portion 3 so as to obtain conductivity equivalent to that of a nonbreakage portion.

摘要： PURPOSE:To provide a high luminousity and efficiency DC type plasma display pannel with a wide operation margin. CONSTITUTION:A selection anode 14 is provided at a front plate 11 and cathode 15 and a maintenance anode 16 are also provided on a back plate 12 so as to be vertical to the selection anode 14. The anode 16 can be used commonly to an adjacent cell. Since among conventional anode functions only the selection discharge function is required for the anode 14, an electrode with a narrow wire width or a transparent electrode can be used, and as a result, the opening rate of a display cell is improved, thereby increasing the luninousity and luninous efficiency. The anode 16 and cathode 15 are formed on the same surface of the back plate 12 with good accuracy, which provides a uniform operation characteristic, thereby reducing maintenance discharge current so as to improve luninous efficiency. By the adoption of tranparent electrode to the selection anode 14, the opening ratio is further increased.

摘要： PURPOSE:To obtain the compsn. for detection having high quality and safety and excellent dispersibility and printability of a reagent, etc., by using potassium iodide as an oxidizability indicator and additively using cellulose or cellulose deriv. CONSTITUTION:A grape sugar oxidizing enzyme GOD and a hydrogen peroxide decomposing enzyme POD are added to the pretreated adsorbent calcium triphosphate to be subjected to ball mill treatment and thereafter, the low substitution degree type hydroxypropyl cellulose L-HPC which is added with the oxidizability indicator potassium iodide and is pretreated is added thereto and the mixture is subjected to a ball mill treatment to obtain a powder mixture. Amyl alcohol, butyl cellosolve acetate, blue dye, etc., are uniformly mixed and dissolved and thereafter, span, K1 gel and various resin liquids are successively added to the mixture to obtain the binder liquid mixture. The previously prepd. powder mixture is gradually added under stirring to this liquid mixture to obtain the ink compsn. Further, a test piece for inspection is obtd. The test piece obtd. in such a manner is immersed in the anodic liquids to be inspected of various concns. and is immediately taken out. The color is uniform and bright if the formed color is observed. The coloration density is proportional to the concn. of the grape sugar.

摘要： PURPOSE:To enable simultaneous coating of plural kinds of viscous materials by discharging the viscous materials from plural discharge nozzles onto a continuously traveling base material sheet, coating the materials onto the sheet and leveling off the respective viscous materials on the down stream of the nozzles. CONSTITUTION:The base material about sheet 2 is left off from a feed roll, travels at a specified speed under the plural discharge nozzles 13 and is taken up on a take-up roll. The viscous materials A-C are supplied at a specified flow rate from respective constant rate discharging machines 14A-14C to the respective discharge nozzles 13 and are coated in the form of continuous band-shaped films from the nozzles 13 onto the sheet 2 during the travel of the sheet. The sheet 2 to which the materials A-C are stuck is then passed between a surface smoothing roller 15 and a supporting roller 16 by which the viscous materials are leveled off and smoothed to a uniform thickness. The sheet is thereafter dried by passing a dryer 17. The band-shaped reagent layers 3-5 are thus formed.

摘要： PURPOSE:To enable complicated printing to be carried out, by a method wherein a screen printing plate having a recessed part in conformity with a from of a thick film pattern on the back of a plate surface is used and another pattern is printed on a printing surface on which the thick film pattern is formed. CONSTITUTION:A plate hole 3, a part to which ink is transferred, is provided at the central part of a plate surface 4, and a recessed part 5 is provided around a plate hole 3 on the back 4' of the plate surface. The plane form and section form of this recessed part 5 are manufactured so as to conform to a pattern 1. Then, when a screen printing plate is placed on a matter to be printed which has a pattern 1, close adhesion of the screen printing plate to the matter to be printed is kept. Further, a probjected part 6 whose an inner contour is almost equal to a contour of the plate hole 3 is provided all over between the plate hole 3 equivalent to a pattern 2 of the back 4' of the plate surface and the recessed part 5. Then, on printed matter, the pattern 2 is enclosed by the pattern 1 and both are formed in close vicinity to each other.
