Abstract: A purpose of this invention is to provide an apparatus which can carry out a deodorization/odor-removal/disinfection work even on a large-scaled matter such as a room etc. effectively and efficiently. A deodorization/odor-removal/disinfection apparatus of this invention is equipped with an ozone generator (1), an ozone blow-off mechanism which blows generated ozone from a blow-off port (12), a device (2) which atomizes aqueous hydrogen peroxide, and an aqueous hydrogen peroxide blow-off mechanism which blows the atomized aqueous hydrogen peroxide from a blow-off port (32). This apparatus generates ozone and at the same time produces aqueous hydrogen peroxide under atomized state, makes the both contact each other and then makes them contact with an object.

Abstract: A duster of an improved type for dust capturing efficiency, comprising a cylindrical stem with a continuous spiral thread extending along a portion thereof, a grip engaged with said stem, and fabric materials comprising a band of fiber or fibril bundles which are made of a ductile synthetic resin film or foil which has been split into fibers or fibrils and crimped. The bundles are arranged in a meandering manner. One edge of the band comprises loose edges while the other edge is held together by one or more strings. The secured edge is disposed within the thread with the ends of said material being engaged, respectively, by a supporting member provided at the tip of said stem and an engaging member provided at the root portion of the thread.

Abstract: A method for manufacturing a duster and the duster manufactured therefrom are described, the duster head being made of strands of a blend polymer film of a mixture of isotactic polypropylene and polyethylene, which has been processed to be in an electret state, so that dust collecting and holding efficiency are improved and gross bulk, and texture of the head of the duster are highly improved with rich resiliency and a convenient usage being provided.
