    Abstract: An arc runner has a pair of side panels covering movable contacts and fixed contacts from a width direction of a movable contactor, a back panel covering the movable contacts and the fixed contacts from a longitudinal direction of the movable contactor, and a top panel covering the movable contacts and the fixed contacts from above, is formed of a magnetic material, and guides arcs to be generated between the movable contacts and the fixed contacts when the movable contacts and the fixed contacts separate from each other, toward an upward direction of the movable contactor. Furthermore, the arc runner includes, in a central portion of the top panel, a top panel hole flow-path area which is larger than top-panel to side-panel gaps formed between the side panels and the top panel.

    Abstract: Disclosed is a low-temperature regenerative type refrigerator installed in a low temperature environment, in which a cooling water flow rate controller for adjusting the flow rate of cooling water automatically in accordance with the temperature of gas fed to an expansion unit from a compressor, is provided in a water cooling type cooler for cooling the compressor, to keep the temperature of the gas discharged from the compressor high to the extent of not deteriorating the function of a seal due to shrinkage or not causing convection or deflecting flow in a regenerator, whereby it is made possible to prevent the deterioration in the cooling efficiency of the regenerator which is caused by a lowering of the ambient temperature in the refrigerator installed place, and hence possible to prevent the deterioration of the refrigerating capacity as the entire refrigerator.

    Abstract: 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.

    Abstract: An object of the present invention is to obtain a superconductive magnet, the size of which can be reduced by shortening the radial length of a magnetic device thereof and the refrigerating performance of which can be improved. A cylinder for fastening a refrigerator has an end facing an ambience of helium gas evaporating in a helium chamber and another end which is substantially horizontally fastened to a vacuum chamber. Further, the three-stage regenerative refrigerator is inserted and fastened to the cylinder for fastening the refrigerator. A heat insulator, such as a convection prevention tube, made of a hollow Teflon tube is wound around the outer surface of each stage of the cylinder of the three-stage regenerative refrigerator. The convection prevention tube is enclosed into a gap between the cylinder for fastening the refrigerator and the three-stage regenerative refrigerator without no undesirable gap so that heat convection of the helium gas is prevented.
