摘要： PROBLEM TO BE SOLVED: To carry out slicing work by a wire saw by covering an outer peripheral surface of a conductor of high strength applied with coppering with a resin bond layer containing abrasive particulates of a specific grain diameter and a filler in resin having a specific elastic modulus and softening temperature. SOLUTION: A conductor 2 is made by applying coppering on a piano wire. Abrasive particulates 3 are fastened on an outer peripheral surface of this conductor 2 of high strength by a resin bond 5 layer. As these abrasive particulates 3, super-abrasive particulates like diamond are favourable, and those of more than 2/3 of thickness of the resin bond 5 layer and less than 1/2 of a diameter of the conductor 2 are used. Additionally, as resin bond 5, resin an elastic modulus of which is more than 100 kg/mm2 and softening temperature of which is more than 200 deg.C and in which a filler 4 a grain diameter of which is less than 2/3 of thickness of the resin bond 5 layer is included is used. Fastening power of the conductor 2 and the resin bond 5 layer is improved and flexibility is also improved by carrying out surface treatment applied on the conductor 2 by coppering.

摘要： PROBLEM TO BE SOLVED: To provide a manufacturing method of a wire saw and the wire saw whereby slicing work or the like of a silicon wafer can be performed. SOLUTION: In this manufacturing method of a wire saw, after a core wire 1 of high strength is made to pass in mixed paint mixing an abrasive grain 3 and a filler 11 in a resin solution, the mixed paint adhering to the core wire 1 is squeezed while rotating a die 2 having a recessed part B in an internal peripheral surface, the abrasive grain 3 is positioned spirally on a peripheral surface of this core wire 1 to be guided to a baking furnace, and this mixed paint is baked on the peripheral surface of the core wire 1 to be secured. In this case, the secured abrasive grain in a manufactured wire saw is formed to protrude in helical shape on the core wire to be sharpened.

摘要： PROBLEM TO BE SOLVED: To firmly fix the abrasive grain by containing a filler of the prescribed grain size in a resin having the prescribed elasticity and softening temperature, and to form an abrasive cutting edge and a tip pocket from the beginning by the raise of the abrasive grain. SOLUTION: A core wire 1 is formed by a roving 2, and its outer circumferential surface is covered with a coating in which the abrasive grain 3 and a filler 4 are mixed in a solution where the resin is solved in the solvent by a resin bond 5 formed through baking and hardening. The grain size of the abrasive grain 3 is not less than 2/3 of the thickness of a resin bond layer, and not more than 1/2 of the diameter of a fiber body, and the resin bond 5 is formed of a resin of not less than 100 kg/mm in elasticity and not less than 200 deg.C in softening temperature. The resin contains the filler 4 whose grain size is less than 2/3 of the thickness of the resin bond layer.

摘要： PROBLEM TO BE SOLVED: To improve a function by forming constricted sections to an airtight flexible jacket, in which one end is installed to a corrugated weir and the other end onto a river-bed and which is extended in the downstream direction, at regular intervals. SOLUTION: A Jacket 11 consisting of a flexible membrane is disposed on the downstream side of a corrugated weir 1 crossed over a river, and one end 11a is joined with the rear surface of the weir 1 and the other end 11b with a ribbed-bed A. The jacket 11 is pulled to the river-bed A by wires 12-15, and stepped irregularities composed of constricted sections 12a-15a are formed while the other end 11b side is lowered gradually. When a fluid is poured into the weir 1 and the jacket 11 and the weir 1 and the jacket 11 are expanded, a stepped water flow close to natural environment is formed towards an upstream, and the overall width of the river is used as a fish ladder 10 suiltable for the ascent of fishes. When the fluid is discharged from a port 3 at the time of the nonuse of the fish ladder 10, the fish ladder 10 is brought down and a water flow capable of reaching the weir 1 disappears. The fluid is discharged from a port 2 at the time of a swelling and the weir 1 is brought down, and a sufficient river cross section is ensured. Accordingly, the gradient and shape of the fish ladder can be formed freely.

摘要： PROBLEM TO BE SOLVED: To improve the function of a fish ladder by expanding a flexible jacket disposed along a corrugated weir for a cutoff by a fluid and lowering the height of the flexible jacket from one end to the other end. SOLUTION: A corrugated weir 1 for a cutoff consisting of a flexible membrane is crossed over a river and installed onto a river-bad A, and a fish ladder 10 composed of a flexible jacket 11 is extended on the downstream side of the weir 1 along the corrugated weir 1. Height is lowered gradually towards the other end section 1 from one end section of the jacket 11 under the state, in which the jacket 11 is supplied with a fluid and expanded, and the height of the end section 14 is set in height, in which fishes are transferred to the corrugated weir 1, while the height of the other end section 15 is set in height, in which fishes are transferred from the river to the fish ladder 10. When a water flow ride acrosses the corrugated weir 1, fishes ascend from the end section 15 of the fish ladder 10 to the end section 14, and ride across the corrugated weir 1. When the fish ladder 10 is not used, the fluid is discharged and the jacket 11 is shrunk, and the fluid in the corrogated weir 1 and the jacket 11 is discharged and both the weir 1 and the jacket 11 are brought don at the time of a swelling. Accordingly, fishes can be made to ascend smoothly.

摘要： PROBLEM TO BE SOLVED: To provide a water cut-off structure which is just installed without special fixing work. SOLUTION: A temporarily constructed water cut-off structure comprises a pair of flexible bag bodies 10, 20, wherein the respective bag bodies 10 are provided with water supply and discharge openings 11, 21 and with exhaust ports 21, 22, and the opposite surfaces of the bag bodies 10, 20 are separably connected to each other by band-like members 13, 23. When a water flow (w) works on the water cut-off bag body 10, though the bag body is about to roll clockwise, it receives the force of rolling counter-clockwise to prevent rolling of the water cut-off bag body 10, because the supporting bag body 20 is connected to the member body 10 through the band-like members 13, 23.
