Abstract: The invention discloses a fastening member with external threads, which is capable of mating with a fastening member with internal threads via the external threads and the internal threads; each external thread includes a leading flank and a trailing flank; the external thread further includes an oblique surface extending between the leading flank of the external thread and the trailing flank of the external thread; a joint between the oblique surface of the external thread and the leading flank of the external thread is farther away from an axis the external thread, compared with a joint between the oblique surface of the external thread and the trailing flank of the external thread; the oblique surface of the external thread is attached against the oblique surface of the internal thread. The invention also provides a threaded fastening assembly.

Abstract: In a self-contained plug-in display cabinet system (100), the evaporation temperature of the evaporator (25) is between ?4° C. and 2° C., and with the adaption of constant pre-cooling means (22), the high-temperature and high-pressure refrigerant gas discharged by the compressor (21) is pre-cooled allowing use of a low system pressure ratio and, thus, a high temperature compressor (21). Furthermore, there may be no need for the evaporator to be defrosted, which overcomes the drawbacks of the currently available display cabinet systems that the refrigeration cycles have to be interrupted for defrosting the evaporator, thereby having further energy saving and being advantageous in keeping the temperature of the food stable.

Abstract: A medium- and low-temperature integrated refrigerating/freezing system (40) comprises an integrated unit (41), a medium-temperature refrigerating cabinet (43), a low-temperature freezing cabinet (42) and corresponding connecting pipes (44). The integrated unit (41) further comprises a common condenser (54) for condensing the high-temperature and high-pressure gaseous refrigerant in the medium-temperature refrigerating system and the low-temperature freezing system, a common reservoir (55) for the storage of the high-temperature and high-pressure liquid refrigerant in the medium-temperature refrigerating system and the low-temperature freezing system, a subcooling adjusting mechanism (56, 57) for adjusting the subcooling degree in the low-temperature freezing system and a suction temperature adjusting mechanism (431, 432, 58) for adjusting the suction temperature of the low-temperature freezing system.

Abstract: A medium and low-temperature integrated refrigeration/freezing system (100) has the function of discharge gas defrosting. It comprises medium and low-temperature compressors sets (120, 122) and medium and low-temperature evaporators, as well as control valves (141, 142, 143, 144), adjusting valves (145, 146), one-way valves (147, 148) and expansion valves (150, 152, 154), and the switching between a refrigerating cycle and the discharge gas defrosting cycle is performed by the combination of actions between multiple control valves. When a first control valve is opened, a second valve is closed and a fourth valve is closed to the refrigerant pipeline to said reservoir, the refrigerating cycle operation is performed; and when the first control valve is closed, the second valve is opened and the fourth valve is closed to the refrigerant pipeline of an intercooler (128), the discharge gas defrosting operation is performed.

Abstract: The present invention provides isolated nucleic acids and proteins that are new and distinct members of the bHLH-PAS superfamily of transcription regulators. These “MOPs” (members of PAS) are useful in a variety of research, diagnostic and therapeutic applications. Several of the MOPs of the present invention are ?-class hypoxia-inducible factors. Several other of the MOPs of the invention are involved in circadian signal transduction.
