摘要： PROBLEM TO BE SOLVED: To make an activated carbon adsorbent dust-free. SOLUTION: The surface of an activated carbon particle is coated with a coating layer consisting of a thin resin film with fine holes. The coating layer is formed of an acrylic resin. The activated carbon particles each other are integrally formed with the coating layer. A chemical agent adsorbing acidic gas or basic gas is stuck on the activated carbon particles. A method for preparing it comprises a process wherein the activated carbon particles are immersed in the treating liquid, a process wherein a resin solution is stuck on the surface of the activated carbon particles and a process wherein at the same time when a coating layer is formed by heating and drying, the treating liquid is evaporated to form fine hols. At the same time when the coating layer is formed, the activated carbon particles each other are stuck together with the coating layer to integrally form them. As the treating liquid, a solution of the chemical agent adsorbing an acidic gas or a basic gas is used.

摘要： PURPOSE:To prevent charging of wafers, to decrease the amount of adhesion of particles to the wafers and to improve the yield of products, by arranging semiconductors or metal wires which are in contact with the wafers in the insides of grooves so that the grooves communicate with one another, and providing grounding terminals. CONSTITUTION:A side plate 13 is manufactured with a nonconductive material such as polypropylene and tetrafluoroethylene resin and the like. A plurality of grooves 12 for holding wafers 10 are formed at the inside of the side plate 13. Conductive semiconductors or metal wires 17 are arranged in contact with the wafers in the grooves 12 so that the grooves 12 are communicated without adverse effects on the semiconductor elements. Grounding terminals 17a and 17b are provided so that the metal wires 17 are brought into contact with a grounding member 18. For example, said metal wires 17 and the grounding terminals 17a and 17b are manufactured with the following materials: thin wire of platinum and the like which are not corroded with chemicals and the like; and thin films of conductive semiconductors such as doped silicon which do not give adverse effects on the semiconductor elements even if the films are corroded with chemicals.

摘要： PROBLEM TO BE SOLVED: To suppress the amount of gas to be generated from a wiring cable and enhance cleanliness in a clean room. SOLUTION: An adhesive is applied to one surface of a polymer organic film 2 of an ethylene, vinyl alcohol copolymer, polyethylene, polypropylene, or polyester, or the like, then a wiring cable 1 used in the clean room is covered with the polymer organic film 2. The generation of organic gas is suppressed even if a CV cable, a CE cable, a flame retardant crosslinked polyethylene cable, or the like, usually generating very small amount of organic gas, is used. The effect on suppressing the generation of the organic gas is furthermore enhanced by bonding a metal foil onto the one surface of the polymer organic film, or laminating the polymer organic film on the upper surface of the metal, and preventing the exposure of the metal at ends.

摘要： PROBLEM TO BE SOLVED: To provide an outgas generation inhibitor which effectively inhibits (curtails) the emission amount of an outgas such as ammonia gas to be bleeded from the constituent material of a clean room or a structure as well as a method for inhibiting an outgas-generation phenomenon. SOLUTION: This out-generation inhibitor is composed of a microcapsule, including a photocatalyst, attached to an outgas treating material. The photocatalyst is preferably of an anatase-type titanium dioxide before any other materials. The microcapsule is preferably of such a construction that the wall material obtained by an interfacial reaction method is an inorganic (especially, silica with high light-transmission is preferable) porous material. The method for inhibiting an outgassing phenomenon is to cause an outgas to come into contact with the outgassing inhibitor.
