Inventor: SHIMAMURA TAKASHI
IPC: H02M3/28
Filed: 1995-02-22
Abstract: PURPOSE: To reduce the discharge current flowing from a snubber circuit to a main switching element and reduce switching loss by sufficiently delaying the saturation time of a saturable reactor even if there is a wide range of delay in input voltage. CONSTITUTION: Discontinuous period between the second period and on period of a main switching element FET by applying a signal to the gate of the main switching element FET by the series circuit composed of a saturable reactor MA', a resistor R1 , and a first capacitor C1 series with the control winding of a transformer T. In that case, the saturable reactor MA' is provided with a secondary winding of second polarity, and the series circuit of the secondary winding of this saturable reactor MA' and the second capacitor C2 is connected in parallel with the main switching element FET, thus the saturation time of the saturable reactor MA' is delayed enough regardless of a wide range of ripple of the input voltage. Hereby, the discharge current flowing from a snubber circuit to the main switching circuit FET decreases, and switching loss can be reduced.

IPC: C02F1/40
Filed: 1997-03-13
Abstract: PROBLEM TO BE SOLVED: To extend the range capable of being covered with one scum skimmer. SOLUTION: Scum is sucked from a scum skimmer 5 along with water, and discharged through a suction pump 4, a rotary air-lift pipe 1, a fixed air-lift pipe 2 and a scum transfer pipe 6. When the scum removing device is intermittently operated for a short time to suppress the lowering of the water purifying efficiency, the rotary air-lift pipe 1 is alternately rotated back and forth by the motor 12 provided with a reduction gear. Consequently, the scum suction pipe 4 and skimmer 5 directly connected to the rotary air-lift pipe 1 are alternately rotated back and forth to cover almost the entire surface of a storage tank C. Accordingly, the range where the scum is not sucked in is not practically left in the large storage tank even with a small number of scum skimmers.
