Abstract: A method of recording fingerprints in which a solution of monohydrogen or dihydrogen ester having an AAV of about 9 or more is applied to a person's fingerprint area with the area then pressed onto a thermosensitive substrate.

Abstract: A coating method for a coating liquid includes preparing a coating surface which has a plurality of regions that are to be coated with said coating liquid; providing a plurality of storage chambers under atmospheric pressure in which said coating liquid is stored in respective amounts that enable the coating surfaces of said corresponding regions being coated to be coated to substantially the same coating thickness; disposing said corresponding regions being coated on the undersides of said storage chambers; and applying said coating liquid on the coating surfaces of said regions being coated by pushing said coating liquid stored in said storage chambers by said atmospheric pressure.

Abstract: After a first processing solution is spread over the front surface of a substrate and the temperature of the front surface of the substrate is regulated at a predetermined substrate temperature, a second processing solution is spread over the front surface of the substrate. The second processing solution can be spread while the front surface temperature of the substrate is maintained at the predetermined substrate temperature. Hence, a layer insulating film with good adhesion properties can be formed uniformly on the front surface of the substrate, and the quantity of the processing solution to be used can be reduced.

Abstract: The present invention relates to a chemical treatment process which makes it possible to modify the chemical structure of securities, bank notes or paper documents during their transportation or their storage, either in a vehicle or by a man on foot, thus making it impossible for criminals to be able to reuse them.

Abstract: A method of forming a perovskite thin film includes preparing a perovskite precursor solution; preparing a silicon substrate for deposition of a perovskite thin film, including forming a bottom electrode on the substrate; securing the substrate in a spin-coating apparatus and spinning the substrate at a predetermined spin rate; injecting a perovskite precursor solution into the spin-coating apparatus thereby coating the substrate with the perovskite precursor solution to form a coated substrate; baking the coated substrate at temperatures which increase incrementally from about 90° C. to 300° C.; and annealing the coated substrate at a temperature of between about 500° C. to 800° C. for between five minutes to fifteen minutes.

Abstract: A process solution applying apparatus comprising a substrate holding mechanism for holding a substrate, a process solution supplying system for applying process solution in a prescribed amount to the substrate held by the substrate holding mechanism, the process solution supplying system having a supplying mechanism for changing a rate at which the process solution is supplied, and a substrate rotating mechanism for rotating the substrate holding mechanism, thus rotating the substrate at a predetermined speed to spread the process solution by virtue of centrifugal force and to coat the substrate with the process solution.

Abstract: A process of coating a refractory turbine part with a protective coating which is ultimately diffusion bonded to the part. A slurry coating material is prepared from a mixture of a silicon alkyd paint and suspended particles of an aluminum or aluminum alloy powder. Parts may be dipped in the slurry and subsequently be heat treated in selected atmospheres and temperatures to diffuse the coating into the surface of the part.

Abstract: This invention is directed to apparatus and a method for removing particles from a surface, such as a semiconductor wafer. A fluid is applied to the surface on which the particles are distributed so as to coat the particles with the fluid. At least some of these particles have a dimension of less than approximately one micron. A suction force is applied in the vicinity of the surface after applying the fluid so as to remove from the surface the majority of those particles having the dimension of less than approximately one micron.

Abstract: A method of applying a layer of a flowable material to a substrate. The substrate is received with a rotatable chuck, and an amount of the flowable material is dispensed on to the substrate. The substrate is spun on the rotatable chuck, thereby spreading the flowable material across the substrate and conveying a surplus amount of the flowable material away from the substrate. An exhaust stream is created with a vacuum source. At least a portion of the surplus amount of the flowable material conveyed away from the substrate is entrained into the exhaust stream, which exhaust stream is conveyed into an exhaust system. A pressure drop is created in the exhaust stream across a vane anemometer within the exhaust system. The blow back of the entrained portion of the surplus amount of the flowable material from a downstream position in the exhaust system to the substrate is thereby reduced.

Abstract: A method for creating a pattern by applying varying concentrations of pigment in water to a synthetic fabric and allowing the pigment to bleed and preferably to reverse bleed. A pleated window shade having an Aurora Borealis like pattern is also provided. The preferred method comprises the steps of stretching a pleated synthetic fabric window shade vertically, applying pigment in water to the surface of the fabric and allowing the pigment to bleed, then inverting the fabric so that the pigment in solvent bleeds in the opposite direction. Optionally, the method further includes at least one of the steps of applying the solvent, such as for example water, to the pigmented surface before inverting or after inverting thereby inducing additional bleeding, blending, and dilution of the pigment in the wetted area.
