Abstract: PURPOSE:To enable to efficiently re-utilize waste heat by a method wherein the hot  water left-over in a bathtub after taking bath is sent to a heat exchanger in a hot  water storage tank by the action of a pump in order to heat-exchange when the temperature in the hot water storage tank is lower than that in the bathtub. CONSTITUTION:When the temperature in a solar heat collector 10 exceeds the water  temperature in the hot water storage tank 1 during the sun shines, the temperature of  the respective temperature detectors 13 and 14 are compared at a controller 15 and  heat transfer medium is circulated in the collector 10 and a second heat exchanger 11  so as to heat-exchange with the water 20 in the hot water storage tank 1 in order to  turn the water 20 into hot water. After that, the hot water 20 is lead from a hot water  outflowing port 17 into the bathtub 3 by opening a faucet 18 due to the water pressure  applied to a feed water port 16. In this case, when the hot water temperature in the  bathtub 3 is higher than that in the hot water storage tank 1, the pump 4 is put into  operation by com-paring the hot water temperature in the bathtub 3 with that in the  hot water storage tank 1 with a controller 8. As a result, the hot water 20' in the  bathtub 3 is heat-exchanged with the water 20 in the hot water storage tank 1 in order to raise the temperature of the water 20.

Such compound is then coated onto substrate 1 to form magnetic layer 2 and then to be used as the magnetic recording medium (Fig. a). The true signals are recorded on the magnetic recording medium mentioned above via the recording current of I 2 , and then the false signals are recorded via the recording current of I 1 . As a result, the true signals could not be read because of coexistence of the false signals (Fig. b). Thus the erasing current of I 3  is applied to erase the false signals recorded on the low magnetism keeping power magnetic powder. As a result, the true signals recorded on the high magnetism keeping power magnetic powder can be read (Fig. c).
