    Abstract: PURPOSE:To measure the liquid level of a low-temperature refrigerant bringing a superconductig magnet to a cryogenic temperature without giving heat to the low-temperature refrigerant by connecting a gas flowmeter to a liquid helium cryostat, processing the flow rate of the evaporating gas of the low-temperature refrigerant measured by a converter and indicating the liquid level. CONSTITUTION:An electric type gas flowmeter 20 is connected to a draw-out- in port 17 for liquid helium in a cryostat A, and the flow rate of helium gas evaporated by a liquid helium tank 7 is measured and integrated by an integrator 21. An analog signal corresponding to the flow rate of the gas is converted into a digital signal by an A-D converter 22, and inputted to an arithmetic processor 23. Physical various conditions, such as the shape and volume of the liquid helium tank 7, the quantity of liquid helium 8, the conversion coefficient of a liquid-a gas, etc. are memorized previously to the arithmetic processor, and the residual quantity and liquid level of liquid helium are obtained on the basis of the inputted flow rate. The result of arithmetic operation is displayed to a CRT display 24 as the quantity of liquid helium reducing with the lapse of time.

    Abstract: PURPOSE:To supply a low flow rate of gas in a gaseous state under a weightless condition, by mounting a heat source for boosting the inner pressure of a tank and a pressure detector in a storage tank, and meanwhile, constituting a pressure regulating tank such that the pressure therein can be maintained at a value within an allowable range. CONSTITUTION:A temperature signal by a temperature detector 11 is fed back, and a pressure regulating tank is maintained at a given temperature higher than the liquefying temperature of gas through the working of a heater 9. A pressure is monitored by a pressure detector 10, and when the pressure in a pressure regulating tank attains an allowable lower limit, a secondary valve 13 is closed, a primary valve 12 is opened, gas, in which a liquid phase 2 and an air phase 3 are mixed, is guided from a storage tank 1, and when the pressure detector 10 finds that the pressure in the pressure regulating tank attains the allowable upper limit, the primary valve 12 is closed. In order to increase the internal pressure of the storage tank 1 to a value higher than the allowable upper limit pressure of a pressure regulating tank 7, the internal pressure is increased to a given value by heating the storage tank by means of a heat source 4 for boosting a pressure.

    Abstract: PURPOSE:To facilitate the production of a supporting structure for an aluminum spherical tank by inserting the connecting end of the lower end portion of aluminum skirt in a recess groove of a steel aluminum skirt supporting member. CONSTITUTION:The bonding end 2 of an aluminum skirt 1 is merely inserted into the recess groove 4a of the aluminum skirt supporting member 4 of a steel skirt 3, and both skirts 1, 3 are constructed to be moved freely from one another. Since the deformation of the aluminum skirt 1 does not affect the influence of the steel skirt, the skirt 3 may merely support the vertical load of the aluminum spherical tank, thereby enabling to simplify and reduce the weight of the structure of the skirt 3.

    Abstract: PURPOSE:To provide a simple structure easily constructible and quality controllable by attaching heat insulating panels, in which polystyrene foam member is used as the main heat insulating member, to the tank body with bolts and filling the joint of panels with a foaming agent. CONSTITUTION:A heat insulating panel consists of a main heat insulating member 7 made of polyurethane and other materials, and polystyrene foam members 8 treated for flexibility and having high contraction and expansion properties, which is placed around the main insulating member 7. Each panel is joined to the other after the insulating bolt 12 provided in its center is installed on the stud nut 11 welded on the tank 1, and polyurethane foam (injection foaming agent) 18 is filled in the joint of the panels. If the heat insulating members contract more than the tank 1 due to some low temp. contents, the displacement due to the contraction is absorbed primarily by the polystyrene foam material 8. Shoud the tank be cracked, the leakage escapes through the clearance between the tank and the members constituting the heat insulating structure.
