  • Compressor and oil amount management system for compressor
    Patent number: 9689593
    Abstract: A compressor compresses a coolant gas returned from a refrigerator and supplies the coolant gas to the refrigerator. A compression capsule compresses the coolant gas and cools compression heat generated by compressing the coolant gas, using oil. An oil separator separates and stores the oil contained in the coolant gas compressed by the compression capsule. A capsule oil level gauge that measures an oil level in the compression capsule. A separator oil level gauge that measures an oil level in the oil separator.

  • Cooling system and maintenance timing determination method
    Patent number: 9217593
    Abstract: A cooling system includes a refrigerator and a thermal load application unit applying a thermal load to the refrigerator. A detector detects, when the thermal load is applied to the refrigerator by the thermal load application unit, a change in a physical quantity generated in the refrigerator or a refrigerator-mounting portion where the refrigerator is mounted. A determiner determines a maintenance timing of the refrigerator based on the change in the physical quantity detected by the detector.

  • Cryogenic cooling apparatus
    Publication number: 20050126187
    Abstract: A cold head of a refrigerator is secured to a support stage provided separately from a cryostat so that the support stage supports the load of the cold head. On the other hand, a low-vibration stage for supporting a load of an object to be cooled is secured to a top flange of the cryostat. Thus, vibration that occurs due to the refrigerator is prevented from being transmitted to the entire cryostat and the object to be cooled.
