IPC: H01L29/861
Filed: 1990-02-15
Abstract: PURPOSE:To reduce a surge voltage at the time of recovery by distributing a part having a high-speed recovery characteristic and a part having a low-speed recovery characteristic by diffusing a lifetime killer substance selectively in the whole of an anode region or a cathode region. CONSTITUTION:An anode region 3 wherein an impurity of a P-type conductivity type is diffused is provided on a semiconductor substrate of an N-type conductivity type which is to be a cathode region. When a lifetime killer substance is diffused selectively in a part of the anode 3, the substance is diffused only from the surfaces of parts 3a and 8a of the anode 3, due to the presence of an oxide film 4 operating as a mask. Accordingly, the concentration of the lifetime killer substance is high in a part 6, while the concentration thereof is low in other parts since the substance is not made to stick thereto positively, and thus a part having a high-speed recovery characteristic and a part having a low-speed recovery characteristic are distributed. According to this constitution, it is possible to maintain the high-speed recovery characteristic and further to reduce a surge voltage.

Abstract: PROBLEM TO BE SOLVED: To make it possible to separate and settle air bubbles sticking to floating sludge by agitating the sludge in a vessel by the floating effect of the air injected into a sludge layer, then allowing the sludge to stand still and restarting the charging of the excess sludge. SOLUTION: The amts. of supernatant water and the thick sludge are balanced and the position of the sludge boundary is stabilized by repeating the cycle motion of charging the excess sludge, then allowing the sludge to stand still and executing thickening, removing the thick sludge in the bottom and executing the next charging. In a high-water temp. season, such as summer or hot season, however, gaseous nitrogen and anaerobic gases are formed and is adhered in the form of the air bubbles to the sludge. The sludge partly floats, giving rise to the formation of the floating sludge (b). The air is injected from the air discharge port 6a of an air piping 6 by opening an actuator valve 7 at such time. As a result, the inside of the vessel is agitated and the high-concn. floating sludge (b) and the intermediate water (c) are mixed.  The concn. of the floating sludge (b) is thinned and the air bubbles sticking to the sludge is made easily partable. The settlement in the form of the sludge not contg. the air bubbles is thus accelerated.
