Filed: 1988-01-09
Abstract: PURPOSE:To improve a rate of recovery of Hg contained in the title waste water by separating a heating tank into an acidic first tank packed with a specified metal and an alkaline second tank packed with a reducing agent, and feeding waste gas of a closed gas-liquid separating tank back to the waste water from the first and the second tank again. CONSTITUTION:Waste gas 2 from an incineration furnace 1 is fed to a cooling tower 3, and discharged washing water 5 contg. Hg is transported to a heating tank 6. The heating tank 6 is separated into an acidic first tank 7 packed with a metal 10 having higher electronegativity than Hg and an alkaline second tank 8 packed with a reducing agent. By this constitution, metallic Hg deposits in the first tank 7 by the reaction of Hg<2+> in the waste water with the metal 10. The metallic Hg is transported in the form of Hg vapor 14 to a cooler 15, and then to the gas-liquid separating tank 18 in the form of liquid Hg 17. The gas-liquid separating tank 18 is closed tightly, and liquid Hg 17 is recovered from its bottom, and Hg vapor 14 is discharged as waste gas 19 and fed back to the first and the second tank 7, 8 again. Thus, the reaction in the first tank 7 is prompted by the stirring effect of air. On one hand, the Hg vapor 14 in the waste gas 19 of the second tank is brought back to a reduced state, and unreacted Hg<2+> is volatilized in the form of metallic Hg.

Filed: 1984-01-09
Abstract: PURPOSE:To increase the yeild of products by obtaining n type layers with less defect by a method wherein the n type layer of the titled device of n<+>p-i-n-p<+> structure is formed by the diffusion method. CONSTITUTION:n<+> Type layers 6 are formed on both main surfaces by deeply diffusing the V-group element such as phosphorus to a low concentration n type (i type) semiconductor substrate 1, and the width of the i type layer 1 is adjusted by lapping removal by including one n<+> type layer 6. Then, a p type layer 2 is formed by diffusing the III-group element such as Ga. The surface part of the n<+> type layer 6 where the impurity concentration is high is removed by lapping, thus leaving an n type layer 6a; then, a p<+> type layer 4 is formed by diffusing the III-group element such as boron only to the surface part. n<+> Type layers 5 are formed by selective diffusion of the V-group element such as phosphorus only on the side of the p type layer 2 into a required pattern. Since the n<+>p-i-n-p<+> structure is formed only by the diffusion method, the manufacturing cost can be reduced.
