  • Method for drying resin-used electronic parts
    Patent number: 6045743
    Abstract: Provided is a method for drying resin-used electronic parts which comprises enclosing resin-used electronic parts together with both an oxygen absorbent requiring no moisture for absorption of oxygen and a drying agent in a container having a gas barrier property and then sealing the container and removing oxygen and, preferably, then heating the sealed container. Thereby, no quality deterioration due to oxidation and degradation of a metal surface occurs in a drying step of resin-used electronic parts.

  • Inhibitor parcel and method for preserving electronic devices or electronic parts
    Patent number: 5510166
    Abstract: Disclosed are an inhibitor parcel comprising (a) a composition comprising an unsaturated fatty acid compound as its main ingredient and (b) a permeable diffusing-parcelling material prepared by laminating and bonding an oxygen-permeable resin layer onto one side of a base sheet made of a fibrous material and an adhesive or onto one adhesive-coating side of a base sheet made of a fibrous material, then laminating and bonding thereonto an oxygen-permeable resin layer and laminating and bonding a porous film of low softening point resin or a low softening point unwoven fabric onto the other side of the base sheet, said permeable diffusing-parcelling material (b) having an oxygen permeability of 10.sup.4 to 10.sup.6 ml/m.sup.2.Atm.Day and a (water vapor permeability/oxygen permeability) ratio of 0.02 H.sub.2 O mg.Atm/O.sub.2 ml! or above at 25.degree. C.

  • Method of preserving article with an oxygen absorbent composition
    Patent number: 5378428
    Abstract: A method of preserving an article which includes enclosing the article and an oxygen absorbent parcel in a container having gas-barrier properties and sealing the container. The parcel is formed by packing an oxygen absorbent composition with a gas permeable packing material, the oxygen absorbent composition containing an linear hydrocarbon polymer having one or more unsaturated groups or a mixture of the polymer with an unsaturated fatty acid compound, an oxidation promoter, a basic substance and an adsorption substance.

  • Oxygen absorbent composition and method of preserving article with same
    Patent number: 5286407
    Abstract: An oxygen absorbent composition containing a linear hydrocarbon polymer having one or more unsaturated groups or a mixture of a linear hydrocarbon polymer having one or more unsaturated groups with an unsaturated fatty acid compound and an oxidation promoter as essential components and optionally containing a basic substance and/or an adsorption substance; an oxygen absorbent parcel formed by packing the oxygen absorbent composition with a gas-permeable packing material; and a method of preserving an article by means of same.
