    • PROBLEM TO BE SOLVED: To enable a matter adhered on a floor to be efficiently removed, by equipping a supply regulator to supply a prescribed amount of coolant from a coolant storage container onto a remover and blowing the coolant through a nozzle to a matter adhered on a floor to cool and harden the matter to make the matter be easily crushed. SOLUTION: When a matter 51 adhered on a floor, such as chewing gum, is to be removed, the adhered matter 51 is covered by a hood 25 for cooling, a prescribed amount of coolant such as liquid nitrogen, low temperature carbon dioxide gas, etc., is supplied to a coolant discharging nozzle 14 from a coolant storage container 11 of a cooling means 10 through a supply amount regulator 15 to discharge the coolant into a hood 25 for cooling through the nozzle 17 to cool and harden the matter 51 so as to be brought into an easily crushable condition. Next, a crushing cutter 21 detachably equipped on a crushing cutter holder 26 on the lower end of an elevating and rotatable shaft 22 is rotated to crush the matter 51. The crushed matter 51 is, after that, sucked by action of a suction blower 34 to recover the crushed matter into a bag 32 for recovery.

    • PROBLEM TO BE SOLVED: To make one cleaning product perform a plurality of wiping functions by arranging an integrated joint part each between a base layer of a thermoplastic synthetic resin, a dirt trapping layer laminated on the base layer and a cover layer laminated on the dirt trapping layer intermittently in one direction. SOLUTION: A wiping sheet is rectangular as demarcated by side rim areas 16 parallel with each other and end rim areas 14 parallel with each other orthogonal to the side rim areas 16 and is constituted of a base layer 21 of a thermoplastic synthetic resin contacting the bottom surface of a header, a dirt trapping layer 22 laminated on one side of the base layer 21 and a cover layer 23 laminated on the dirt trapping layer 22 partially covering the layer 22. The dirt trapping layer 22 is arranged at the central area across the width of the base layer 21 except for the side rim areas 16 and individual filaments 22A are continuously extended between the end rim areas 14 arranged side by side with the side rim areas 16. A plurality of open holes 24 are arranged at a portion overlapping the dirt trapping layer 22 of the cover layer 23 and the filaments 22A are exposed.

    • PROBLEM TO BE SOLVED: To prevent the generation of the laceration in a fluoroplastic layer and to certainly remove the contaminant of the fine recessed parts of the fluoroplastic layer by coating the surface of a membrane structural material with a soln. containing a film forming substance mixed with fibers and drying the layer of the coating soln. to form a film and peeling this film. SOLUTION: The surface of a membrane structural material is coated with a soln. containing a film forming substance such as water-soluble polyvinyl alcohol or water dispersible methyl acrylate mixed with synthetic fibers such as viscose or acetate fibers or glass fibers and, after coating, the coating material is dried not only to evaporate a solvent but also to take in the contaminant bonded to the surface of the membrane structural material by the film forming substance to form a film. Next, the formed film is peeled. By this constitution, since the soln. containing the film forming substance certainly flows in the fine recessed parts of the surface of the membrane structural material, the contaminant of the fine recessed parts can be also removed at the same time.
