摘要： In a multi-stage cold accumulation type refrigerator including a compressor disposed at an ordinary temperature, a helium gas as a common operating fluid to be compressed by the compressor, and one or more expansion chambers and cold accumulators of different temperature levels; a cold accumulating member of the cold accumulators is formed of an alloy or compound containing a rare earth metal, so that the efficiency of the refrigerator can be improved. Further, a heat generation quantity due to sliding resistance of a seal is set to be smaller than a theoretical generated refrigeration quantity to be obtained on the assumption of isothermal expansion in the expansion chambers, so that the refrigerating capacity can be improved. The refrigerator is applied to a cooling device for cooling a superconducting magnet, SQUID, superconducting computer, infrared telescope, etc.

摘要： A chip part (6) is mounted on bus bars (2, 3), and connection portions (6t) of the chip part (6) are soldered to the bus bars (2, 3), respectively. At this time, recesses (10, 11) are beforehand formed respectively in soldering lands of the two spaced-apart bus bars each corresponding to a predetermined solder wetting area. The chip part is soldered to the bus bars in such a manner that the connecting portions are spaced apart from inner edges of these recesses, respectively, thereby forming a solder fillet between at least part of each of the recesses and the corresponding connecting portion of the chip part.
