摘要： PURPOSE:To shorten a processing by automatically deciding the damaged position of a coated film in accordance with the waveform characteristics obtd. by detecting the potential difference of the ground surface by the leak current from the damaged part and smoothing and differentiating twice the potential difference by a computer after A/D conversion. CONSTITUTION:A voltage is impressed between the buried pipe 2 and a grounding point 3 from a signal transmitter 1 and the potential of the ground surface generated by the leak current from the damaged part is measured. The potential difference is detected by a signal receiver 6 on a vehicle connected to a rotary electrode 4 or the like and is digitized by an interface 7 from which the potential differential is sent to a personal computer 8. The computer 8 smoothes the digitized original waveform for the purpose of noise removal and executes twice the differential processing thereof, then the computer decides the damaged position of the coated film from the size and sharpness of the peak thereof. The results thereof are displayed on a display 9, etc., and are marked on the road surface in the damaged position by an automatic road surface marker 20.

摘要： PURPOSE:To prevent an underground pipe line from being corroded, by inserting an inner pipe in an outer pipe having its inner surface covered with an electrical insulator, with a predetermined gap therebetween in which a filler is charged so that corrosive current or the like can be blocked. CONSTITUTION:The inner surface 11 of an outer pipe 1 in which inner pipes 2 is inserted with a predetermined gap therebetween, is covered with an insulating paint such as a paint containing therein glass flakes, a tar epoxy paint, an epoxy paint, an asphalt or the like, or an electrical insulator 3 such as polyethylene, FRP, vinyl or the like. A filler such as sand mortar, cement mill or the like is charged between the gap between the inner and outer pipes. The inner pipes are joined together by welding or using mechanical joints. As a result, the pipe line is protected against corrosion, uniformly in its entirely, by means of the coating in a double structure. Further, a stray current of a macrocell corrosive current can be blocked and so forth.

摘要： PURPOSE: To uniformly coat the inside of a pipe even which may have a bent part of small radius of curvature, by forming at least rear one of two pigs between solventless paint is interposed from a spherical body having elasticity, and transferring each pig with fluid pressure from the backside.
CONSTITUTION: A preceding pig 2 and a rear pig 3 comprising an elastic spherical body are inserted into a pipe body 1 such as a steel pipe, and solventless paint 4 is interposed in a space therebetween. The backside of the pig 3 is affected by fluid pressure such as air pressure, pressure difference is held between the front and rear sides of the pig 3, and said paint 4 is transferred through the pig 3. Hence, the film of said paint 4 is formed on the inner surface of the pipe body 1. As a material for forming the pig 3, rubber, soft synthetic resin, etc. may be used. As said paint, a substantially solventless type is preferable, and its viscosity is 200W600 poise at an ordinary temp. (0W40°C). By this method, the formation of a uniform coating film can be performed, said uniform coating can be applied onto piping even which may have small radius of curvature, and the labor of treatment after the application processing can be remarkably curtailed.

摘要： PROBLEM TO BE SOLVED: To provide a water storage tank in which no water retains. SOLUTION: A central flow is formed by making discharged water from a first branch pipe 25 hit on a mirror plate 12 (arrow mark 1) and counter flowed (arrow mark 2). The fear of generation of vortexes on corner sections of the mirror plate 12 by the flow of the arrow 2 is eliminated. Then a helical flow (arrow mark 3) is formed by flowing the discharged water from a second branch pipe 26 along an inner wall 11a. Water is returned to a water feed pipe through an outflow pipe 30 by sucking water in the vicinity of another mirror plate 13 shown by the arrow mark 4. The discharged water from the first branch pipe 25 is made to heat the mirror plate 12 and counter flowed by the arrangement to form a central flow, and the discharged water from the second branch pipe 26 is flowed along inner wall 11a to form a swirl flow. As no water remains, the fear of deterioration of water is eliminated.

摘要： PROBLEM TO BE SOLVED: To wind a steel plate in an elastic range, and to prevent to from being an elliptical shape by bending the steel plate into a cylindrical tubular body, mounting contracting jigs on the inside of the tubular body whose edge portions are not joined with each other yet, and connecting two inner surface points by the jigs to substantially form a diameter after the contraction to contract the plate edge portions of the tubular body. SOLUTION: Contracting jigs 2 are mounted on an inner surface of a cylindrical tubular body 1-1 whose edge portions are not joined with each other yet. Connection pieces 3A, 3B are mounted on plate end portions of an inner surface of an inner steel plate after winding and contraction at the position symmetrical in the right- to -left direction. The connection piece 3B is mounted at the position with the overlapping margin (winding margin) on the inner steel plate subtracted. Connection pieces 3C, 3D are mounted at the positions on the opposite side to the connection pieces 3A, 3B by 180 deg. form a diameter with the connection pieces 3A, 3B. The connection pieces 3A, 3C, and the connection pieces 3B, 3D are connected to each other by the contracting jigs 2, respectively. The diameter is reduced to the diameter of the tube to be contracted by the jugs 2. Then, the plate end portions of the inner steel plate are temporarily welded to an inner surface of the tube, and the contracting jigs 2 are detached.

摘要： PURPOSE:To obtain a water reservoir with a simple structure which makes smooth the horizontal and vertical water circulation in the water reservoir and prevents the water from stagnating. CONSTITUTION:A water reservoir is provided with an inflow pipe 2 and an outflow pipe 3 in the inside of the reservoir horizontally installed in the ground to use the water repeatedly. The inflow pipe 2 is connected to one end of the water reservoir 1 and the outflow pipe 3 is connected to the other end thereof. And an outlet 21 is provided at the end plate 11 of one end of the reservoir where the inflow pipe is connected and the peripheral position. And further, a spiral rib 22 having a specified shape is attached near the outlet 21, along the inner periphery of water reservoir to generate a whirl flow. A suction opening 31 is provided at the end plate of the other side of the water reservoir where the outflow pipe 3 is connected. In this way, a simple-structural and low cost water reservoir can be fabricated and it prevents stagnation of the water.
