Title: Insulation vessel
Inventor: ITO SUSUMU
IPC: H01F6/04
Filed: 1988-04-27
Abstract: PURPOSE:To reduce the amount of evaporation of saved liquefied gas, by comprising an outside vessel at least partially provided with magnets in the upper and lower parts and the shell and an inside vessel which is housed in said outside vessel and which is made of superconductivity in parts opposed to said magnets. CONSTITUTION:When an inside vessel 22 is at an ambient temperature, the inside vessel 22 composed of superconductivity, is normal conductivity state. The bottom of the inside vessel 22 is in contact with the bottom of an outside vessel 24. When liquefied gas 10, such as liquefied nitrogen is injected into the inside vessel 22 from an injection nozzle 23, the inside vessel 22 is cooled below a critical temperature and is moved to superconductivity state. As a result, repulsion due to minus effect acts between permanents magnets of the outside vessel 24 and the inside vessel 22 so that the inside vessel may be supported in the air within the outside vessel 24 without any contact with the outside vessel 24. Therefore, the inside vessel 22 is immune to the outside heat transmitted by heat conduction from an insulation vessel 20, and placed under thermally insulated state, which makes it possible to reduce the amount of evaporation of the liquefied gas 10.
