摘要： PROBLEM TO BE SOLVED: To reduce gas generated after sealing in high vacuum in a vacuum heat insulating material by a method wherein a printing method for a packing material of a getter to be put into a vacuum heat insulating material wherein a core material is inserted into an airtight container, and after the inside is made highly vacuum, the container is sealed. SOLUTION: A PET film as thick as 12 μm with a getter for vacuum heat insulating material endlessly printed in Mincho-writing type at 5 mm intervals using a carbon dioxide gas laser marker and a PE film as thick as 30 μm are laminated. Thereafter, after fine vent holes are opened mechanically, 5 g of molecular sieve 13X is filled, and heat-welding is performed to obtain a pillow-shaped packaging bag. This bag package is put into a stainless steel vacuum chamber with an internal volume of 750 cc, and a pressure is reduced at 0.001 Torr for 10 minutes. Thereafter, a rise in pressure in the vacuum chamber is observed as time passes by a capacitance manometer by a pressure raising method, and a pressure rise is measured 30 minutes later. The pressure reaches 0.002 Torr, showing that there is little gas generated.

摘要： PROBLEM TO BE SOLVED: To retain a heat-insulating capacity for a long period, by limitting the total gas volume permeating from the end face of a plastic film laminated in the inside of metallic foil of an external bag within a specified volume. SOLUTION: Heat fused plastic films are laminated in the inside of a gas- barrier layer including a metallic foil to form an external bag made of a vacuum heat-insulation material. Most of gas permeates from the heat fused layer into the external bag. The permeating volume is proportional to the gas permeability of the film. And hence, A heat fused plastic film of which total permeation gas volume is 0.08μL/day or smaller per 1 lit. of the inner volume of the vacuum heat-insulation material at 25 deg.C, 50% RH atmosphere, is used, in the gas permeation from the end face of the plastic film laminated in the inside of a metallic foil of the external bag of the vacuum heat-insulation material. In this way, even if a getter is not used against gas permeation from the outside, the heat- insulating capacity can be retained for a long period.

摘要： PROBLEM TO BE SOLVED: To obtain a getter as a gas absorbent to remove gas and to make a heating process at high temp. to remove the water content from a getter unnecessary, by preparing a getter from a water absorbent comprising a physical water-adsorbing material and a chemical-absorbing material, and an oxygen absorbent which does not require a water content for adsorption of oxygen. SOLUTION: The vacuum getter to be used for a vacuum desiccator and the like consists of a water absorbent comprising a physical water-adsorbing material and a chemical water-absorbing material, and an oxygen absorbent which does not require a water content for absorption of oxygen. The both absorbents are housed in a same closed space of a gas barrier type sealed container. Thereby, the water content which is held in the physical water- adsorbing material and/or in the oxygen absorbent which can be desorbed in vacuum is transferred to the chemical water-absorbing material and chemical fixed. After the water absorbent and oxygen absorbent are housed in a same closed space of a gas barrier sealed container, these absorbents are preferably further heated to obtain a dry state. The heating temp. is specified to 40 to 150 deg.C.

摘要： PURPOSE: To prevent the deterioration of bare chips while they are stored temporarily in a manufacturing process and while they are kept on a shelf as stocks to maintain the quality of the chips in a good condition by tightly sealing the bare chips in a container having gas barrier properties from which oxygen and moisture has been substantially removed. CONSTITUTION: It is necessary to simultaneously create such a condition that the inside of a system is substantially free from oxygen and at a low humitity. A condition in which oxygen has been removed means that concentration of oxygen is 5% or less, preferably 1% or less, more preferably 0.1% or less. And a condition in which moisture has been substantially removed means that relative humidity is 10% or less, preferably 5% or less, more preferably 1% or less. Bare chips are tightly sealed in a container having gas-barrier properties together with oxygen absorbent which requires no moisture to absorb oxygen and dehumidifying agent. The oxygen absorbent is composed of, as principal agent of oxygen absorbing reaction, unsaturated fatty acid compounds and/or straight-chain hydrocarbon polymer having unsaturated groups, accelerator for accelerating oxygen absorbing reaction of the principal agent, and carriers, and preferably further composed of acid gas absorbent.
