  • 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: 10330469
    Abstract: A bank angle detection device for a motorcycle includes a bank angle estimator configured to estimate a moving body bank angle ?b and a correcting section configured to estimate a vehicle body bank angle ?f. The bank angle estimator estimates the moving body bank angle ?b that is a gradient of a moving body axial line A1, on the basis of a balance state where a centrifugal force CF acting on a moving body and a gravitational force GF acting on the moving body during cornering are in balance with each other. The correcting section corrects the moving body bank angle ?b on the basis of an inertia force about a longitudinal axis acting on a vehicle body, so as to estimate the vehicle body bank angle ?f that is a gradient of a center of gravity G of the vehicle body with respect to a vertical line.
