Filed: 1996-03-12
Abstract: PROBLEM TO BE SOLVED: To always cool a liquid agent at very high efficiency by sending the compressed air to an air blow member for the disperse blow thereof from blow holes to the liquid agent, and cooling the liquid agent in direct contact with the blown air as a refrigerant. SOLUTION: The compressed air generated with an air compressor 2 is reserved in a pressure tank 7 and when a temperature sensor detects the rise of the temperature of a liquid agent in a liquid tank 1 above an established temperature range, an open/close valve 4 is opened, thereby sending the compressed air from the pressure tank 7 to an air blow member 8 via a feed pipe 3. The compressed air blown from the blow holes of a pipe 9 forming the air blow member 8 rises in the liquid agent like a continuous columnar form or an air bubble form. As a result, the the compressed air cools the liquid agent until being released from a liquid level and at the same time, the compressed air agitates the liquid agent for enhancing cooling efficiency.

Filed: 1990-03-30
Abstract: PURPOSE:To simplify a circuit to be processed by permitting a detection circuit to detect that respective bits of data which are read from a memory are coincident when respective outputs of a coincidence/non-coincidence detection circuit coincide and respective outputs of a selector coincide. CONSTITUTION:When one of the output lines R1-4 at every two bits from the coincidence/non-coincidence detection circuit 10 is a '0'-output, namely, non- coincident, an output line R6 outputs '0' by a NAND gate G4. Even if data are errored in two bits and all the outputs of the output lines R1-R4 are coincident, the non-coincidence of read/write data (RWD line) D9-D12 is detected in an exclusive NOR (XNOR) gate G1 and the output line R6 outputs '0'. Consequently, an eight bits parallel test at the time of X1-constitution can be conducted without errors. Thus, the circuit to be processed can be simplified.
