摘要： PURPOSE:To apply to a machine requiring a large stroke under a pressurized fluid, simplify a sliding seal device, and reduce its cost. CONSTITUTION:When a movable member (sliding shaft) 4 is reciprocated, a sliding seal plate 2 mounted on the movable member 4 is brought into contact with an elliptic seal member 1 mounted on the peripheral part of an elliptic hole 8a with a determined pressing force in such a manner as to be capable of sliding to fluid-tightly seal up a machine body 8. Although the corner part (part other than the center of a semicircular part) of the elliptic seal member 1 receives an oblique unbalanced load, then, this part is thickened, causing no lip inversion or the like.

摘要： PURPOSE:To measure the mass flow rate of flowing fluid highly accurately in real time by providing a horizontal U-tube at a part of a fluid pipe line, and providing both strain gages for measuring bending moment and for measuring axial tension at the connecting part of the tube and the pipe line. CONSTITUTION:A bending-moment measuring strain gage 5 and an axial-tension measuring strain gage 6 are stuck to a joint 3. A 0 point is set under the state wherein mixed fluid 1 is not present. A fluid weight rhogV in a U-tube 4 is measured with the bending-moment measuring strain gage 5 as the bending moment M=rhogV(e+e') in a vertical plane. The resultant force F of centrifugal forces acting on the U-tube 4 is measured with the axial tension measuring strain gage 6 as the axial tension of F=2rhoV.V /(r+d/2). Here, the distance (r) between a center 7 of the U-tube 4 and the inner wall, the diameter (d) of the U-tube 4, the distance (e) between a center of a figure 8 and the center 7, the distance e' between the center 7 and the gage sticking position and the volume V of the U-tube 4 are known. Therefore, the mass flow rate rhoV can be obtained highly accurately in real time by measuring the bending moment M and the axial tension F.

摘要： PURPOSE:To continuously and moreover accurately measure the flow rate of excavated earth and sand by detecting the sectional area of the excavated earth and sand transported on an earth discharging belt conveyor by a selected cutting method and multiplying the sectional area by the transport speed of the belt conveyor. CONSTITUTION:When excavated earth and sand A discharged from the earth discharging screw conveyor 11 of a shield tunneling machine is transported on a belt conveyor 12, the surface configuration of the earth and sand in the transverse direction of the belt conveyor is optically cut by laser slit light 14 irradiated from a laser beam generator 13 and the appearing profile 14' of the surface of the excavated earth and sand is continuously taken up by an ITV camera 15. The sectional area of the excavated earth and sand A is obtained from an optically cut image 14' thus obtained. By multiplying the sectional area by the transport speed of the belt conveyor 12 measured by a speedometer 20 mounted thereto or the like, namely, the moving speed of the earth and sand, its flow rate is obtained. Thus, the flow rate of the excavated earth and sand can be continuously and moreover accurately measured.

摘要： PURPOSE:To prevent a group of heat transfer pipes from being excited and vibrated by a fluid flowing through the pipes, by contacting a vibration stopping metal fitting to the heat transfer pipes. CONSTITUTION:A rectangular vibration stopping metal fitting 4A of which thickness is smaller than its width is inserted between rows of heat transfer pipes 2. After insertion, the rectangular vibration stopping metal fitting 4A is turned round at 90 deg. in order to let it contact to the heat transfer pipes on the wider side of the metal fitting 4A. By this method, the contacting state of the metal fitting 4A to the heat transfer pipes 2 is improved, and vibration of the group of heat transfer pipes caused by being excited by the flowing fluid can be suppressed.

摘要： PURPOSE:To completely prevent leak of water through the outer periphery of a steel pipe, by a method wherein an initial tightening force is previously exerted on waterproof rubber located to the outer periphery of a steel pipe water channel, and after concrete placed on the outer periphery of the waterproof rubber is cured, the initial tightening force is released. CONSTITUTION:Waterproof rubber 12 is disposed to the outer periphery of a steel pipe water channel 11, and a loading plate 13 and a tightening bolt 14, having the forward end threadedly attached to the loading plate 13, are inserted into a hole 12a formed in the waterproof rubber 12. A nut 15 is threadedly fastened to the base end screw part of the tightening bolt 4 to exert an initial tightening force on a waterproof rubber 12 through the loading plate 13. Concrete 17 is placed in the outer periphery of the waterproof rubber 12 to form a side wall 3 of a water tank 1. By releasing the initial tightening force by unscrewing the nut 15 after the concrete 17 is cured, the waterproof rubber 12 is expanded to block a gap between the concrete 17 and the waterproof rubber. This enables complete prevention of leak of water in a water tank 1 through the outer periphery of the steel pipe water channel 11.

摘要： PROBLEM TO BE SOLVED: To properly excavate a tunnel having a prescribed cross-section using the tunnel excavator without attaching an additional excavating device at its peripheral part. SOLUTION: The body of the excavator consists of a front body 11 and a rear body 12. A small-diameter cutter head 13 capable of rotating while driving is mounted at the front part of the front body 11, a first roller cutter 14 is mounted about at the central part of the front surface of the cutter head 13, and a second roller cutter 15 inclined in one direction is pivoted to the peripheral part of the front surface. The cutter head 13 is formed so as to be eccentrically-oscillated in the excavated surface by an eccentrically oscillating drive mechanism 18. Under the eccentrically oscillating operation of the cutter head 13, the second roller cutter 15 is rotated so as to turn to the inside and outside of the excavation surface by a second cutter rotating mechanism 23.

摘要： PROBLEM TO BE SOLVED: To reduce treatment cost by treating and recycling building sludge in generated-soil treatment. SOLUTION: A dispersant J, cement F, water glass G and hydrochloric acid H are added to dehydrated cake E, and agitated and mixed by an agitating mixer 37, and internal substances are parted and granulated by a disintegrating and granulating machine 38, thus forming granular bodies 1. Each loading of the dispersant J, cement F, water glass G and hydrochloric acid H is adjusted by a controller 50 on the basis of the moisture content of dehydrated cake E measured by a moisture-content measuring device 51 and the quantity of fine particles measured by a fine-particle quantity measuring device 2 at that time.
