Abstract: A method and an apparatus for decomposing halogenated hydrocarbon gas economically and stably without relying on any special treatment and without generating dioxins. A catalyst to decompose halogenated hydrocarbon gas, 4, is supported on a carrier 3. A target gas, which contains the halogenated hydrocarbon gas, is passed through the carrier 3, while heating the carrier 3 using an electromagnetic induction heating mechanism 5, 6.

Abstract: The object is to provide a method and an apparatus for decomposing halogenated hydrocarbon gas economically and stably without relying on any special treatment and without generating dioxins. The apparatus includes a carrier supporting a catalyst for decomposing halogenated hydrocarbon gas, wherein the carrier is resistant to a halogen-containing gas and is electrically conductive, the halogenated hydrocarbon gas passing through the catalyst which is supported by the carrier; and a heating mechanism for heating the carrier by an electromagnetic induction heating.

Abstract: A soil or soil improver for plants which is characterized by combining a charcoal or activated carbon on which oxygen is adsorbed with a soil or soil improver comprising an inorganic or organic ion exchanger and a porous mineral, and a soil or soil improver which further comprises polyacrylamide. By using the soil or soil improver of the invention, plants can continue to grow for four months to one year without supplying water and fertilizer, and various decoration patterns of plants are possible, such as horizontal decoration, reverse decoration and space decoration.

Abstract: A cooling box is divided into cooling chambers, and each of the cooling chambers is communicated with a water pipe, so that each of the water supplies is independent. If a front part of the cooling box were lost by melting due to wearing of bricks in the furnace, cooling by the rear part of the cooling box would be available. Therefore, it is no longer necessary to substitute a new cooling box for an old one, since the cooling box by the invention could go with until the last period of the furnace and damages could be avoided of the furnace bricks in vicinity of the cooling box, which is caused inevitably by substituting a new cooling box for the old one.
