摘要:
There is provided a panel structure for an electronic apparatus that is capable of exhibiting two types of design images. During daytime hours for example, a design-applied portion of a panel main body can be visually recognized through a panel made of a light transmitting material. During nighttime hours for example, when light is conducted from one X direction-wise end to the other x direction-wise end in the panel, as well as from the other x direction-wise end to one X direction-wise end in the panel 1, the design-applied portion is shielded with the light illuminating the panel. In this way, by making a difference between the daytime visual impression and the nighttime visual impression of the panel, it is possible to impart two types of design images to the panel structure.
摘要:
An alcohol production system that produces alcohol by alcoholic fermentation using a saccharide solution, including an alcoholic fermentation vessel in which the saccharide solution is fermented by adding yeast to produce alcohol, which is an organic feedstock, and a biomass-hydrothermally-treated-product adding means that adds a biomass hydrothermally-treated product obtained by hydrothermally treating a biomass feedstock to the alcoholic fermentation vessel. The alcohol production system can improve alcoholic fermentation efficiency and realize cost reduction without adding only a mineral salt from outside.

A mercury reduction system includes an NH4Cl supplying unit that sprays an NH4Cl solution into a flue of the boiler, a reduction denitration apparatus that includes a denitration catalyst for reducing NOx in the flue gas with NH3 and oxidizing Hg in the presence of HCl, and a wet desulfurization apparatus for reducing Hg oxidized in the reduction denitration apparatus with limestone-gypsum slurry. The NH4Cl supplying unit includes an NH4Cl solution feed pipe that supplies the NH4Cl solution into the flue in a liquid state, a blow pipe that is inserted into the flue so as to surround the NH4Cl solution feed pipe and through which air is injected into the flue, and a two-fluid nozzle that is fitted to an end of the NH4Cl solution feed pipe and through which the NH4Cl solution is injected. Through the two-fluid nozzle, the NH4Cl solution is injected and sprayed in fine liquid droplets. NH3 is supplied by an ammonia supplying unit and HCl is supplied by a hydrogen chloride supplying unit wherein both units are located between the NH4Cl agent supplying unit and the reduction denitration apparatus.

An air pollutant control system comprises: a denitration apparatus that reduces nitrogen oxide in flue gas discharged from a coal combustion boiler, and that sprays hydrogen chloride into the gas to oxidize mercury, an air heater that recovers heat in gas, a dust collector that reduces dust in gas, a desulfurization apparatus that reduces sulfur oxide in gas from which the dust has been reduced, a hydrogen chloride vaporizer that evaporates concentrated hydrochloric acid to obtain the hydrogen chloride, and a hydrochloric acid neutralization tank where dilute hydrochloric acid discharged from the hydrogen chloride vaporizer or the concentrated hydrochloric acid is neutralized with an alkali agent. Neutralized chloride is supplied to a fuel feeder, mixed with a fuel, and then burned as a fuel in a boiler to produce hydrogen chloride in flue gas. Together with sprayed hydrogen chloride derived from the hydrogen chloride vaporizer, the mercury is reduced.
