、１ことえば活性炭ビ入れることは既に知られている。BACKGROUND OF THE INVENTION Double-walled containers with a vacuum evacuated between the walls are the best insulated containers. Relatively small containers are usually made of glass (thermos), but larger containers can be made with only steel walls. However, the vacuum in the vacuum mantle of an insulated container made of octopus can In particular, it was found that when a radiation-reflecting shield is installed in a vacuum space, it also decreases.This decrease in vacuum is first absorbed by the walls and the radiation shield, and gas is released. Second, gases, such as hydrogen, can diffuse through the steel walls. However, the insulation provided by the vacuum decreases rapidly when the pressure in the vacuum mantle is high (above 10-4 mlJ). It is already known to include a maintaining medium, such as activated carbon.

To minimize the amount of vaporization, add 7 low-temperature melting components to the mixture. To reduce the acid content of the alloy, it is conventionally reduced by adding a known reducing agent (lanthanum, metal, etc.) to it.

Then under a protective gas, the obtained material can be further finely crushed (by hydrogen absorption and release 7 cycles), so that the alloy 9 hydrogen absorption and release It is possible to reduce the particle size of the alloy to less than 1 micron during the process. Release occurs at temperatures of about 100-150°C. However, the reduction in vacuum in the vacuum mantle occurs over a very long period of time, and therefore the alloy particle size A particularly fine powder is not absolutely necessary for use as a vacuum maintenance medium in the alloy mantle, as a high rate of gas absorption is not required. (Applies to hydrogen.) This alloy reliably absorbs gases normally present in the vacuum mantle, such as hydrogen, water vapor, telogen, etc.
