PROBLEM TO BE SOLVED: To provide a frame which is reused by mounting new wire cloth on a plastic material through stripping of wire cloth (158, 159) from a top part of a frame and heating an area surrounding the new wire cloth. SOLUTION: A method of forming the frame for a filter screen from a polymer material is explained. A whole reinforced wire frame is enclosed in the liquid polymer during a frame molding process, and two parallelly spaced wires are extended through each perpendicularly intersecting rib that defines an opened area of the frame on which the wire cloth (158, 159) is spread. A surface of the frame in which the wire cloth (158, 159) is embedded is formed of ridges and topmost parts of the ridges are extended in a different length. The topmost parts are softened by heating during a production process and the wire cloth (158, 159) spread over the frame is pressed into the softened topmost part. Thereafter an assembly grows cold and becomes hard. COPYRIGHT: (C)2008,JPO&INPIT

PROBLEM TO BE SOLVED: To provide a construction method of a frame for a boiler not degrading work efficiency so much even in bad weather while dispensing with a high lift crane. SOLUTION: The top parts of a plurality of steel posts 20 erected beforehand are connected to each other by a beam, and a ninth-floor floor unit F 9 of the uppermost floor is temporarily fixed to the intermediate floor. An eighth-floor floor unit F 8 is then connected to hanging rods 42 hung from jacks 38, and while it is jacked up, floor units F 7 , F 6 of the lower stories than the eighth-floor floor unit F 8 are connected to a plurality of stories on the ground side. After the floor units of the plurality of stories are connected to the ninth-floor floor unit F 9 , temporary fixing is released to move the floor units of the plurality of stories upward, and the respective floor units are mounted to the respective set floors. This process is repeated. COPYRIGHT: (C)2007,JPO&INPIT

PROBLEM TO BE SOLVED: To provide a method for closing a damaged area of mesh of a sieve for screening and to provide an apparatus therefor. SOLUTION: The method is characterized in that a woven wire mesh which is spread over a support, frame including a plurality of windows is fixed in tight-stretched so that the method is applicable to such a type of sieve is in the mesh area where the local damage to the mesh overlaps with one of windows. This method comprises a step of inserting the apparatus to be put on the window closely and a step of fixing the apparatus to the window so that the damaged mesh area is covered. The apparatus may contain a former in which the similar mesh to those spread over the window is spread over and fixed to, or simply a plate or a block. The apparatus may be fixed in the predetermined position by force insertion, fastening insertion, mechanical means or an adhesive and the apparatus may be elastically deformable so that it is pushed in over the protrusion of the window and inserted tightly in the predetermined position.
