Abstract: PROBLEM TO BE SOLVED: To provide a chemical supply device which can feed liquid without the necessity of a pump so as to eliminate the man-hours for the maintenance of the pump so that the total cost of the chemical supply device can be reduced since no special device such as a pump is used, that is, it can feed the liquid only under the gravity. SOLUTION: In a chemical supply device 12, a chemical supply tank 14 is located at a position higher than a position from which chemical is fed, and accordingly, the chemical is fed into a chemical supply position 9 through dropping of the chemical under the gravity. Further, the chemical supply tank 14 is replenished with the chemical from a chemical filing tank 18 in response to a signal delivered form a liquid level sensor 20 which is provided in the chemical supply tank 14. Since only the gravity is used as energy for feeding liquid, no special components including a pump are required, and accordingly, the structure of the device is simplified. Thus, such advantages that the man-hours for the maintenance, and the cost can be reduced, may be effected.  Further, since the chemical supply tank 14 is replenished with the chemical from the chemical filling tank in response to a signal from the liquid level sensor 20 provided in the tank 14, the height of the liquid surface can be restrained, thereby it is possible to provide such an advantage that the chemical can be fed at a stable discharge pressure.

Filed: 1988-09-19
Abstract: PURPOSE:To reduce the influence due to the fault of a power supply system by transferring at least one of plural volumes having the same data for multiplication to the power supply system of another volume. CONSTITUTION:A CPU 1 writes the same data into the volumes 11, 12 and 15 for triplication of a kind of volume. The volume 15 is set under a power supply system different from those of volumes 11 and 12.
