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.

摘要： A cold accumulation type refrigerating machine having a high refrigeration efficiency. Rotation output of a stepping motor is converted to a reciprocative motion of a displacement member carrying a cold accumulator and disposed within a cylinder in which first and second closed chambers are defined above and below the displacement member, respectively. A compressed gas discharged from a compressor is introduced into the second closed chamber through the cold accumulator upon opening of a suction valve and undergoes expansion within the second closed chamber, the gas being then fed back to the compressor through the cold accumulator upon opening of an discharge valve, whereupon one cycle of refrigerating operation is completed. Rotation speed of the stepping motor is varied during every one cycle of operation by means of a pulse oscillation controller such that a time taken for the displacement member to reach a top dead center position from a time point at which the discharge valve is opened is increased while the remaining period of the one cycle is correspondingly shortened.
摘要翻译： 一种制冷效率高的冷堆式制冷机。 步进电动机的旋转输出被转换成承载冷蓄库器的位移构件的往复运动，并且设置在气缸内，第一和第二闭合腔分别位于位移构件的上方和下方。 从压缩机排出的压缩气体在打开吸入阀时通过冷蓄积器被引入第二闭合室，并且在第二封闭室内经历膨胀，然后气体在开启时通过冷蓄积器反馈回压缩机 排出阀，从而完成一个循环的制冷操作。 步进电动机的转速通过脉冲振荡控制器在每一个操作循环期间变化，使得从排出阀打开的时间点起到位移构件到达上死点位置所花费的时间增加 而一个周期的剩余时间相应缩短。
