Abstract: A mat, in which a pile yarn is tufted onto a base cloth and the entire or a part of pile shape is a cut pile. A part of or the entire pile yarn on a mat surface comprises a twist yarn formed by twisting two or more temporary twist yarns together. Each temporary twist yarn is formed by twisting a paralleled yarn comprising a great number of single yarns of one-kind fiber selected voluntarily from BCF nylon, vinylon, rayon, acryl, polyester and cotton; and one or more nylon monofilament single yarns. A number of kind of paralleled yarn fiber is one or two or larger in the entire temporary twist yarn of the twist yarn. In this mat, merits of both: conventional outdoor and indoor mats, can be provided and demerits of them can be compensated.

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 rental mat in which a pile yarn is tufted onto a base cloth and the total or a part of pile shape is a cut pile. The pile yarn is composed of one BCF nylon twist yarn and one or more nylon monofilament single yarns. The BCF nylon twist yarn and the nylon monofilament single yarns are tufted as one pile yarn under a state of being twisted each other, and are separated and isolated respectively from the twisted state at a part of the cut pile on a mat surface.

Abstract: An oil coater for mats which comprises a mat-supporting moving surface, a coating roller disposed above said mat-supporting moving surface and having on the periphery thereof a foam layer capable of being impregnated with an oiling composition, a press roller having a diameter smaller than the diameter of said coating roller and having on the periphery thereof a foam layer capable of being impregnated with an oiling composition, a first bearing mechanism which supports said press roller at a position upstream of said coating roller so that the top face of said press roller is substantially on the same horizontal plane with the top face of said coating roller and the degree of pressed contact between said coating roller and said press roller can be adjusted, a mat-feeding roller disposed below said mat-supporting moving surface, a second bearing mechanism which supports said feeding roller so that the axis of said feeding roller is substantially on the same vertical plane with the axis of said coating roller a
