Title: Method for tempering fly ash contained in combustion gas of boiler
Inventor: HIRATA JIYUNTA
IPC: B03C3/013
Filed: 1981-10-15
Abstract: PURPOSE:To lower the resistivity of fly ash to resistivity facilitating electric dust collection, by directly spraying a tempering agent into the combustion chamber of a boiler. CONSTITUTION:When an electric dust collecting apparatus generates inverse ionization caused by high resistivity of fly ash, a charging state becomes unstable and the current and the voltage of a charging installation show abnormal values. A control apparatus 17 receives this abnormal output to increase the opening degree of a flow amount control valve 15. By this mechanism, the spray amount of a tempering agent such as sodium carbonate or sodium hydroxide is increased and the resistivity of fly ash is lowered. Because of the lowering of resistivity, inverse ionization in the electric dust collecting apparatus 12 is dissolved. As the result, the fly ash in the combustion gas of a boiler can be effectively tempered and the capacity of the electric dust collecting apparatus can be maintained stably.

IPC: H04N5/335
Filed: 1985-07-23
Abstract: PURPOSE:To increase light-gathering power by forming a microlens by an silicon nitride film. CONSTITUTION:An N-type semiconductor region 2 is shaped onto an silicon substrate 1, an silicon oxide film 4 and a polysilicon film 9 are deposited, an silicon nitride film 10 is deposited, and patterning so as to cover sections except the N-type semiconductor region 2 and oxidation are conducted, thus forming end sections covered with the silicon nitride film 10 to a tapered shape. When the silicon nitride film 10 and the upper silicon oxide film 4 are removed and the polysilicon film 9 is oxidized, the silicon oxide film 4 is shaped as the form is left as it is, and the silicon nitride film is deposited on the surface of the silicon oxide film 4 and flattened, thus shaping an silicon nitride lens 5, then depositing the silicon oxide film 4 on the surface of the silicon nitride lens 5. The silicon nitride lens 5 is held by materials having low refractive indices, thus displaying a convex lens effect.
