摘要： PURPOSE:To obtain braking force more than that on an asphalt road surface at the time not only when a road surface is in a frozen state but also when in a dry state by providing protruding strips, each having a triangular section and a slant face, in a sawteeth way on a mat. CONSTITUTION:An elastic rubber mat 1, wherein slant faces 2 are provided on protruding strips 3 while being opposed to the advancing direction of an automobile, is laid on a road surface. This imparts speed reduction action due to gravity as in the case of traveling an up-grade road to a wheel, on a flat road. In downward traveling on a slope, braking action due to gravity as in the case of traveling an up-grade road is imparted to a wheel so as to provide physical speed reduction action. Particularly, car weight partial to front wheels when braking is applied is decreased by the slant faces 2 to secure braking force of rear wheels. Accordingly, braking force more than that on an asphalt road surface can be obtained even when a road surface is in a dry state.

摘要： PROBLEM TO BE SOLVED: To prepare the subject formed product capable of exhibiting excellent cushioning property, durability, abrasion resistance, etc., by pulverizing waste materials of vinyl chloride resin, adding specific amounts of specific fine powders of vulcanized rubbers and a urethane binder to the resultant fine powder and subjecting the obtained mixture to a urethane processing. SOLUTION: This formed product is obtained by adding (C) a urethane binder to a mixture of (A) vinyl chloride resin powder and (B) vulcanized rubber powder, and the resultant mixture is formed into sheets. Preferably, that mixture is prepared by mixing 60-40 pts.wt. of the component A having particle diameters of 1-5 mmϕ and 40-60 pts.wt. of the component B having particle diameters of 1-5 mmϕ, and to 100 pts.wt. of the resultant mixture is added 20-30 pts.wt. of the component C. As the component A, products obtained by pulverizing waste materials of thermoplastic vinyl chloride film or sheet with a crusher can be used. Further, as the component B, products obtained by pulverizing waste materials of industrial rubber products with a crusher can be used.

摘要： PURPOSE:To enhance the workability at a field and to enhance the water- tightness in a sheath pipe system joint, by interposing a packing which is compressed at a specific charge rate and in which the center part thereof is outwardly deformed into an 811918 shape, between a receiving port pipe of a sheath structure and a push pipe on which a thrust preventing part is fitted. CONSTITUTION:A sheath pipe 10 fitted at its inner surface with a stationary ring 20 is welded to the front end of a steel pipe so as to form a receiving pipe, and stopping rings 14 are welded to a steel pipe at a position having a predetermined distance from one end of the steel pipe so as to form a push pipe 11. A packing 13 having inner and outer surfaces on which bent grooves are formed at predetermined intervals, is fitted onto the end part of the push pipe 11, and the one end part thereof is pressed against the stopper rings 14, and a slide ring 19 is fitted thereon on the end side. Further, the push pipe 11 is inserted into the sheath pipe 10 so that the packing is deformed into a bellows-like shape by compression so as to be made into press-contact with the sheath pipe 10 and the push pipe 11, and thereafter, locking bolts 16... are fastened so as to complete the connection of the pipes. In this phase, the charge rate of the packing 13 is set in range of 70 to 130%.

摘要： PURPOSE:To facilitate insertion of a packing so as to prevent the packing from separating by providing a pair of bending grooves whose sections are outwardly deformed in triangle at a center part so as to swell a chevron part so that surface pressure is generated on a copper pipe outer surface at the ridge part of the chevron part when the packing is compressed in the direction of its length and also mounting O-rings on both ends of the packing. CONSTITUTION:The cylinder body 13 of a wave-shape packing is peripherally provided with bending grooves 15 which form the projection parts 18 of chevrons 14 in the center parts of inner surfaces. The bending grooves 16, 17 which form left/right skirt parts 19, 20 of the chevron parts 14 are peripherally provided at regular intervals from the left/right of the bending grooves 15. O-rings 11, 12 which have hardness higher than rubber hardness for the packing and have diameters approximately equal to a clearance between a steel pipe and a sleeve pipe are mounted on both ends of the cylinder body 13 of the wave- shape packing. Hereby, deformation of the cylinder body 13 of the wave-shape packing can be sufficiently retained so as to completely prevent water leakage. Further, the packing is prevented from making separation at the ends of the sleeve pipe.

摘要： PURPOSE:To prevent separation from a packing push ring and an angled packing retainer ring by forming at least a set of grooves, generating bearing pressure on the external surface of a steel pipe at the ridge of an angled section, and making the hardness of a packing end larger than the hardness of a packing intermediate section. CONSTITUTION:Slidable packing push rings 7 are coupled to the most forward ends of steel pipes 1 and 2 as main pipes along the periphery thereof, and fixed type packing push rings 6 fastened to a sheath pipe 3 with ring fastening welding 10 is laid inside like a stopper for acting as a stopper for the rings 7. In addition to this construction, corrugated packing sheets 4 are inserted between an angled packing retainer ring 9 at each end of the main pipes 1 and 2 forming a pipeline and the rings 7, and stoppers 5 welded to both ends of the sheath pipe 3 and the ring 9 are bolted to each other, thereby ensuring the pipeline to be strongly fastened to the sheath pipe 3.
