摘要:
The present invention relates to a labeling enzyme and a method of detecting and/or quantifying a target substance using this labeling enzyme. The present invention provides a labeling enzyme that catalyzes a reaction of gelling a substrate. By measuring changes in physical properties such as the film thickness and/or refractive index of a film produced by the gelling reaction catalyzed by the labeling enzyme of the present invention, it is possible to quickly and highly sensitively detect and/or quantify a target substance while minimizing the effects of coexisting substances.

A process for formation of tin oxide film is described, wherein a glass substrate is heated to a high temperature and then tin oxide film is formed on the surface of said substrate by a thermal decomposition oxidation reaction caused by bringing a tin compound or a mixture of a tin compound and a fluorine-containing compound into contact with the surface of said glass substrate, and wherein prior to the formation of tin oxide film, said glass substrate is preliminarily brought into contact with a solution of chloride of a metal belonging to Group IVB of the Periodic Table so that a layer of a composition containing the chloride of the Group IVB metal as the primary component is formed on the surface of said substrate.

A combined cycle power plant comprises a gas turbine system and a steam cycle system having a steam turbine to be driven by the steam generated by the waste heat of the exhaust gas of the gas turbine system, wherein the steam from the steam cycle system flows through a gas turbine cooling system of the gas turbine to cool the gas turbine blades and other elements of the gas turbine system to be cooled and the waste heat of the gas turbine system is effectively collected. The gas turbine cooling system has two or more than two cooling ducts formed in two or more than two elements of the gas turbine system to be cooled such as the gas turbine blades and the combustor of the gas turbine system so that steam is made to flow through the cooling ducts of these two or more than two elements to be cooled to effectively and maximally exploit the cooling potential and the waste heat collecting potential of the steam and hence improve the overall thermal efficiency of the plant.

摘要:
A display member that provides clear and uniform illumination through a light diffusion layer while enabling a wider selection of display colors that can be applied to the part of the display member body not covered by a light-blocking layer in order to clearly identify the uncovered part when the display member is not illuminated. A display member body is covered by a light-blocking layer. Light irradiating the rear side of the display member body illuminates the front side of the display member body through a displaying part that includes a region where the light-blocking layer has not been applied. The display member body provides a light diffusing effect through a light diffusing layer, and includes a specifically colored transparent layer which is applied over the light diffusing layer and which has greater transparency than the light diffusing layer.
