Title: Freezing cycle
Inventor: SATOU MASAAKI
IPC: F25B41/04
Filed: 1996-03-14
Abstract: PROBLEM TO BE SOLVED: To flow a refrigerant from a high pressure part of the refrigerant to a low pressure part of the same even when the high pressure part of the refrigerant and the low pressure part are reversed in their order following the reversal of the flow direction of the refrigerant by providing a pressure release valve for releasing the refrigerant in a high pressure side piping into a low pressure side piping. SOLUTION: A flow direction of a refrigerant is changed over with a four way valve 2 upon cooling operation and heating operation, whereby a high pressure side of the refrigerant and a low pressure side of the same are reversed. When pressure in a piping 8 on a high pressure side of a freezing cycle exceeds set working pressure of a pressure release valve 6, the pressure release valve 6 is actuated and hence the piping 8 on the high pressure side and the piping 9 on the low pressure side are communicated whereby the high pressure refrigerant is released from the piping 8 on the high pressure side to the piping 9 on the low pressure side until proper pressure is attained to reduce the pressure in the piping 8 on the high pressure side.  Accordingly, when the piping 8 on the high pressure side of the freezing cycle becomes abnormarily high pressure, the high pressure refrigerant is reduced whereby parts and the piping 8 are prevented from being broken down owing to high pressure and stability of the freezing cycle is improved.

Title: Semiconductor device
Inventor: MATSUMOTO AKITO

Filed: 1997-02-26
Abstract: PROBLEM TO BE SOLVED: To achieve the high speed, the large capacity and the large scale of a synchronous SRAM or the like and the high speed and the high performance of an engineering workstation(EWS) or the like containing the SRAM or the like as a cache memory. SOLUTION: In a synchronous SRAM or the like which constitutes a cache memory for an EWS, e.g. a noninverting data line Wtn and an inverting data line Wbn in a complementary data line Wn* which constitutes a memory array are formed by using, e.g. a second-layer metal wiring layer M2 and a third-layer metal wiring layer M3 whose formation height is different. Thereby, the line-to-line capacitance of a noninverting signal line and that of an inverting signal line in every complementary data line are reduced, and the level of every data line is changed at high speed. Inversely, while an increase in line-to-line capacitance is being suppressed, the wiring pitch between the complementary data lines is reduced, and the high integration of the memory array is achieved.
