摘要： PROBLEM TO BE SOLVED: To prevent occurrence of solidification or clogging of paint by electric deposition.
SOLUTION: An aqueous paint coating device is constituted by using combination of materials to hardly generate electric potential difference for a connection part of a metal pipe for paint to a joint to be used for the aqueous paint coating device, and using combination of metallic materials of noble electric potential. Therefore, solidification or clogging of the paint caused by the electric deposition phenomenon at the connection part of the metal pipe for paint to the joint in the paint passage in which the paint stays for a long time can be prevented. In addition, consistent coating can be performed by cleaning and refilling the paint only in a part of the coating passage.

摘要： PROBLEM TO BE SOLVED: To prevent clogging in a transportation pipe and destruction of a valve due to an impact pressure with the powder when it is transported pneumatically. SOLUTION: An opening/closing valve 52 is installed in an exhaust pipe 51 tied with the powder exhaust hole 5 in a powder fluidizing tank, and a porous aeration ring 61 having a diameter the same as the inner diameter of the exhaust pipe 51 is fitted in upstream of the opening/closing valve 52, followed by connection of an aux. air chamber 6 provided with a ring-shaped space 62 at the periphery of the ring 61, and an aux. air pipe 63 to feed by pressure the aux. air to the aux. air chamber 6 is connected as capable of being opened and closed. In particular, the fluidizing air pressure and aux. air pressure are sensed by pressure sensors 73 and 74, respectively, and a control mechanism 7 emits a drive command to vary the air pressures to the optimum values to pressure adjusting valves 71 and 72 for the two air pressures automatically on the basis of the initial conditions stored previously in a control device 75 to effect excellent rationalization.

摘要： PROBLEM TO BE SOLVED: To reduce the burden at site to a great extent by introducing an assist means on a mirror scale for replacing the material such as powder in a powder flow tank and changing to an efficient operation. SOLUTION: A sealed tank 1 having an approx. rectangular cross section is divided into an over-situated powder flow chamber 3 and an under-situated air chamber for flowing 4 by a porous plate 2 laid transversely on the whole section with a mild gradient, and the air chamber 4 is further divided by vertical bulkheads 41 into a plurality of minor air chambers 42A, 42B, 42C... about the inclining direction, wherein the air pressure is adjustable for individual minor chambers. In particular, the adjustment should preferably be made by a controlling mechanism 5 which performs control automatically in conformity to the initial conditions stored in memory in advance. With a decrease of the residual amount, powder P slides smoothly toward the exhaust port owing to the inclination of the porous plate, and further the flow of the powder is promoted through adjustment of the air pressures in the minor chambers so that the powder is allowed to gather at the exhaust port and then exhausted.

摘要： PROBLEM TO BE SOLVED: To prevent a powder from being violently stirred up and flowing out to the outside, when the fluidized powder in a fluidizing tank is consumed and the make-up powder is supplied to replenish the consumed quantity, so as to retain a pleasant working environment. SOLUTION: The powder feed inlet 2 is a cylindrical body provided with the cover face 21 protruded from the top face 11 of a hermetically sealed tank 1 to detachably fit the upper cover 23, and the bottom face 22 projecting to the inside. And a cone 3 with a conical body contained in the cylindrical body is fitted to form an inclined space E narrowed as it goes down between both cylindrical and conical bodies. A powder suction duct 4 wound up on the outer peripheral face 25 of the feed inlet on the top face 11 of the hermetically sealed tank is connected to the inside of the tank at one end 41 and connected to a duct collector 6 at the other end 42 so as to be freely opened or closed. On feeding the powder P, a large quantity of the powder is stirred up, but as the nearby position of the end 41 is always in a negative pressure through the powdery material-suction duct 4, the entrained air passing through the inclined space narrowed as it goes down is sucked while increasing the speed to prevent the stirring-up dust from flowing out to the outside.

摘要： PROBLEM TO BE SOLVED: To provide a polyethylene sleeve for pipe corrosion protection which suppresses a cost thereof, reduces labor of construction, moreover, prevents cleavage from occurring on a joint part of the pipe and prevents the penetration of ground water.SOLUTION: A polyethylene sleeve 11 for pipe corrosion protection is configured such that a foam sheet or an air bubble sheet is overlapped and adhered onto the inner circumferential surface of basic sleeve material 21 as cushioning material 22. Outer circumferences of a pipe 1 to be joined together with a joint part 2 are covered with the polyethylene sleeve 11 respectively over the pipe axial direction, the joint part 2 is covered with the polyethylene sleeve 11 which clads one side pipe 1 and, on the other hand, the polyethylene sleeve 11 gets over the joint part 2 and covers the polyethylene sleeve 11 which clads the other side pipe 1. In the polyethylene sleeve 11, the foam sheet or the air bubble sheet of the cushioning material 22 is soft, is excellent in cushion property, is hardly water-permeable and water-absorptive and is almost moisture-impermeable and, therefore, only by covering the outer circumference of the metallic pipe 1 with the polyethylene sleeve, the occurrence of cleavage accompanied by back-filling of earth and sand, or the like can be prevented.
