IPC: H02M3/28
Filed: 1986-04-04
Abstract: PURPOSE:To prevent the second DC output of a switching power source from decreasing by enhancing the reference voltage of a first DC output at no load time. CONSTITUTION:An output 1 is compared by a voltage comparator 4 with the output of a reference voltage generator 3, and a switching controller 5 controls the driving pulse width of a switching transformer 6 to be stabilized on the basis of a compared result. An output 2 is stabilized by controlling the unstabilized DC output obtained from another secondary winding of the transformer 6 by a dropper 7. A CPU 8 controls a load circuit 9, and feeds a signal to the generator 3 at no load time. The generator 3 receives the signal to enhance the output voltage to the comparator 4. Accordingly, when the output 1 is at no load time, the driving pulse width of the transformer 5 does not extremely decreases to eliminate the decrease of the output 2.

Abstract: PURPOSE: To keep a regenerative container safe against heat, by maintaining the temperature of the container below a maximum service level by a temperature buffer means which comprises a drain valve and a feed water valve.  
     CONSTITUTION: When the heat collection temperature approaches the maximum service level of the regenerative container 1 made of synthetic resin, the drain valve 12 is opened to discharge water. At that time, low-temperature water is supplied to the whole of a heat exchanger 4 through the holes 11 of a water conduit 8 and a ball tap 7 actuated because of the fall in the level of water 9 so that the heat exchanger 4 is instantly covered with the low-temperature water. The drain valve 12 senses the low-temperature water so that the valve closes. The hot water in the regenerative container 1 is thus kept below the maximum service temperature of the container. For heating a room, the hot water is conducted to heaters through circulating pipes 14, 15 by a pump controlled by a heat collection regulating sensor 13. For supplying hot water, heat exchange is instantaneously performed by a heat exchanger 5 of large heat transfer surface and the hot water is conducted through water conduits 5a of the heat exchanger.
