  • Publication number: 20190285339
    Abstract: A raw material gas liquefying device includes a feed line; a refrigerant circulation line; and a controller. In a refrigerant liquefaction route, a refrigerant flows through a compressor, a heat exchanger, a circulation system JT valve, a liquefied refrigerant storage tank, and the heat exchanger, and returns to the compressor. In a cryogenic energy generation route, the refrigerant flows through the compressor, the heat exchanger, an expansion unit, and the heat exchanger, and returns to the compressor. The controller determines if a refrigerant storage tank liquid level is within an allowable range, manipulates a feed system JT valve opening rate to control refrigerant temperature at the high-temperature-side refrigerant flow path exit side of the heat exchanger, and manipulates the opening rate of the feed system JT valve to control the refrigerant storage tank liquid level so that the refrigerant storage tank liquid level falls into the predetermined allowable range.

  • Patent number: 7286080
    Abstract: Provided is a millimeter-wave transmitting/receiving apparatus of pulse-modulation type in which pulse-modulated millimeter-wave signals for transmission are prevented from being outputted to a reception system due to inner reflection or other causes. Included are: an NRD guide (basic structure) formed of a dielectric line sandwiched between parallel plate conductors; a millimeter-wave signal oscillator; a pulse modulator; a circulator; a transmitting/receiving antenna; and a mixer. At the output end of the mixer is disposed a switching device which interrupts intermediate-frequency signals in an opened state, and, when a millimeter-wave signal for transmission from the pulse modulator enters a non-output state and the condition is stabilized, changes into a closed state to pass intermediate-frequency signals.
