IPC: F25B41/04
Filed: 1996-09-27
Abstract: PROBLEM TO BE SOLVED: To obtain an air conditioner of a low cost with small size and small power consumption without influence of instantaneous power interruption. SOLUTION: A normally open type heating solenoid valve 6 is provided at a heating absorption liquid channel L4, and opened without energizing at the time of heating. At the time of cooling, the value 6 is energized and forcibly closed while a temperature in a high temperature regenerator 1 is a predetermined temperature or lower, and when it becomes the predetermined temperature or higher, the valve 36 is stopped. A valve disc of the valve 6 is maintained closed by a pressure from the regenerator 1 due to a temperature rise in the regenerator 1, and the valve 6 is not opened. At the time of heating, even if an instantaneous power interruption occurs, the valve 6 is not closed.  At the time of cooling, when the interruption occurs, if the temperature in the regenerator 1 is low, even if it is opened due to the power interruptions, since the pressure in the regenerator 1 is low, it can be again closed when the power is recovered. When the temperature is high, the valve is hot opened due to the power interruption, but the closure of the valve is maintained. Since the closing drive force of the valve 6 can be reduce, powder consumption is small with a small size.

Abstract: PURPOSE:To hasten the confirmation of an amplifying output due to a sense amplifier at the time of reading memory cell data by amplifying the potential difference in a bit wire pair driven to a complementary level in accordance with the complementary switching action of a transistor to constitute a memory cell. CONSTITUTION:A memory cell MC is composed of a pair of transistors switching-operated complementarily by the difference in the threshold voltage, and in accordance with the complementary switching action of the transistor to constitute the memory cell MC, the potential difference of bit wire BL1-BLn pairs driven to the complementary level is amplified by a sense amplifier SA. Consequently, at the time of reading the memory cell data, the level of a pair of the bit wires BL1-BLn is complementarily forced, and thus, the potential difference necessary to the definition of the amplifying output action due to the sense amplifier SA to detect and amplify the level difference is brought by means of the level change of the bit wires BL1-BLn of both. Thus, at the time of reading the memory cell data, the early confirmation of the amplifying output due to the sense amplifier SA can be executed and further, the reading time of the data can be shortened.
