摘要： PROBLEM TO BE SOLVED: To promote execution efficiency by coating the head of an anchor with a synthetic resin molten material after a synthetic resin water leak prevention sheet is fixed on a ground with the anchor. SOLUTION: An anchor 2 is driven from the upper part of a synthetic resin water leak prevention sheet 1, and the sheet 1 is fixed on a ground 3 of a concrete wall. Then, for example, a die 5 having a space 51 formed in the shape covering the head 21 of the anchor 2 and circumference thereof is fixed to the front end of a molten material extruder 4. Then, the die 5 is brought into contact with a position to which the head 21 is exposed, and the extruder 4 is operated to pour molten synthetic resin 6 into the space 51 through a resin inlet port 52. The die 5 is removed together with the extruder 4, and the synthetic resin 6 is cooled, and the exposed head 21 and circumference thereof is coated with it. By the constitution, the smooth water leak prevention sheet without projection can be used, at the same time, even the existing concrete wall can be easily constructed, the sheet can be easily executed since the head of the anchor can be seen, and a coating state can be confirmed after the execution is carried out.

摘要： PURPOSE: To resist the resistance of a water-conveyance flow in a valve body, to resist even an impact, to impart durability, to improve the flexibility of the peripheral section of the valve body, to enhance sealing properties and to facilitate mounting by simple structure. CONSTITUTION: In a check valve, a shaft body 11 is penetrated to a through-hole 3 being penetrated to the partition wall 2 of a water-conveyance tunnel 1 and functioning as a water through-hole in combination, a sheet-like valve body 2 is connected at one end of the shaft body 11 in the water-conveyance tunnel 1, and a stopper 13 for preventing a slip-off is connected at the other end on the inside. The shaft body 11 receives internal and external pressure, and is moved forward and retreated in the through-hole 3. The sealing surface 14 of the valve body 12 is brought into contact with and separated from the internal surface section 2a of the partition wall 2 as a valve seat surface with the forward movement and retreat of the shaft body 11, and the through-hole 3 is opened only at the time of water passage from the outside to the inside. A projected surface-shaped pressure-receiving surface 15 is formed to the rear of the sealing surface 14 of the valve body 12, and the peripheral section of the valve body 12 is thinned.

摘要： PURPOSE:To restrict movement of warp and uniformalize end distribution and further improve durability by using knitted cloth, knitted with knitting yarn instead of weaving warp and woof with predetermined intersecting angles, for the reinforcing layer of a bead part. CONSTITUTION:With respect to warp 2 which is organic fiber filament such as nylon or the like and fiber group of 5-50 denier, woof 3 of the same quality is arranged so as to intersect, instead of weaving, said warp 2 with density of arrangement with 80-140% of the warp 2 and at an angle of 60-90 deg.. Then, knitted cloth 1 is made with knitting yarn 4 of fine fiber, and, after its undergoing adhesion processing and heat treatment, a ply is made by burying cords in the rubber through topping rubber treatment. The ply is cut at an angle of 20-70 deg. with respect to the warp 2 and made into a strip to be pasted on a bead part. Thus, movement of the warp is restricted, end distribution is uniformalized and further duration is improved.

摘要： PURPOSE:To improve the adhesion performance with rubber by forming a side strand so as not to have the joint part constituted of broken edges, in a steel cored in a multilayer structure which is formed by covering the periphery of a core strand by the side strand. CONSTITUTION:A steel cord 1 is constituted of, for example, a core strand 3 constituted of three filaments 2 and a side strand 4 constituted of three filaments twisted around the core strand 3, and the broken filaments 2 are used as the core strand 3, and the broken edge parts of the filaments 2 are twisted each other to form a joint part J. In this case, the side strand 4 which has not joint part is arranged around the joint part J of the core strand 3 so as to cover the whole, and the point part J is prevented from being exposed to the outside of the side strand 4. Thus, the adhesion performance with rubber in the case when the joint part J is buried into rubber can be improved.

摘要： PURPOSE:To obtain a pneumatic tire with excellent uniformity and durability by using, as reinforcement, a fabric woven with knitting yarn of a fine filament thread. CONSTITUTION:A fabric 1 is made of the warp 2, arranged in parallel with each other, and the loosely arranged woof 3, intersecting said warp 2 nearly orthogonally. Said fabric is formed by uniting the warp and the woof into one body through weaving these warp and woof by means of fine fiber yarns 4 along the longitudinal direction of the warp. After the fabric, thus obtained, undergoes adhesion treatment and heat treatment, topping rubber treatment is further applied to the fabric to form the reinforcement made by burying a cord in rubber. The reinforcement is used for carcass ply, belt ply or bead filler and the like.

摘要： PROBLEM TO BE SOLVED: To enable movement of a gun main body in conformity with a speed of extrusion of a molten resin material, to make a welding width and the like prescribed and thereby to reduce nonuniformity in a welding strength by a method wherein running rollers driven by a driver and designed for moving the gun main body in a floated state are provided in the vicinity of the fore end of an extruding metal fitting. SOLUTION: This extrusion welding machine 1 is equipped with a gun main body 2 extruding a molten resin material B prepared by melting thermoplastic resin and a running implement 3 moving this gun main body 2. Herein a juncture line L of two thermoplastic resin sheets A is formed on one plane. By extruding the molten resin material B along this juncture line L, it is formed for plane welding whereby the sheets A are welded on the juncture line L. The running implement 3 is fixed removably to the gun main body 2, as an integral unit constructed by fitting a frame F with a pair of running rollers 15 disposed in the vicinity of the fore end of an extruding metal fitting 9 and with a driver M2 being a motor or the like for driving these running rollers.
