摘要： PURPOSE:To improve the workability and profitability and eliminate the dispersion due to the personal difference by independently providing a brazing section added with projections and recesses on the surface of a brazing material filled in a metal case and a bond line junction storing brazing materials and foaming resin respectively and integrally forming them. CONSTITUTION:A rail bond 1 is enveloped by a heating agent molded material 2 and is fixed to the head side face R-1 or abdomen side face R-2 of a rail R. A molded material 2 is then burnt to melt brazing materials A and C. The brazing material A of a brazing section added with projections end recesses flows into recesses from projections when melted and is diffused and infiltrated on the rail surface, and bubbles on the rail surface are simultaneously discharged to the outside. Foaming resin B is concurrently foamed at a bond line junction 1-2, the melted brazing material C is extruded to the opened end, the brazing material is infiltrated into the bond line to integrally braze a tube body and the bond. The brazing material A is set higher than the case upper edge by 1-2mm, the depth of grooves formed by projections and recesses is set to 1-2mm, the width of the grooves is set to 1-3mm.

摘要： PURPOSE: To improve working efficiency by accommodating a cement mixture in a container that is formed by combining a non-woven cloth with a hydrophilic polyvinylalcohol resin film. CONSTITUTION: A container 4 of a heading capsule 1 is formed by combining a non-woven cloth 2 with a hydrophilic polyvinylalcohol resin film in the longitudinal direction and thermocompressing them in a bag shape or the like. Also, a cement mixture is accommodated in the container 4 and both the ends are closed. Then, the capsule 1 is dipped into water for absorbing water by the container 4 and then is inserted into a boring hole 6 of a concrete block 8, an anchor bolt 1 is driven for breaking the container 4, and the mixture is allowed to flow out for filling the gap of the hole 6, thus sealing the bolt 7, thus easily manufacturing the capsule, at the same time eliminating such trouble as moisture absorption, and improving working efficiency.

摘要： PURPOSE:To magnify a fine arc trace so as to easily detect the arc trace of an arc horn where any fault current occurs by igniting a heating agent in a metallic container fixed at the end of the arc horn with application of energy of a surge current or a fault current flowing the arc horn. CONSTITUTION:Arc horns 1 are fixed with clamps 23 above and under an insulator string 22 to protect the string 22 from a lightning discharge toward a transmission-distribution line 21. When a fault current caused by a lightning short flows through the arc horns 1 fixed in the insulator string 22, the fault current flows in a heating agent 3 via a metallic container 2 so as to ignite the heating agent 3. The temperature at the container 2 becomes higher by the reaction heat of the heating agent 3 caused by the ignition so that the surface thereof is discolored by oxygen in the atmosphere. With this discoloring, an arc trace caused by the fault current can be displayed magnified. Therefore, the arc trace caused by the fault current can be visually detected with ease.

摘要： PURPOSE:To provide the title device designed to volatilize active ingredients such as a fumigant for vermin control, by sandwiching a match tip chemical in between slide members having match side chemical layer to facilitate ignition confirmation and improve operability. CONSTITUTION:A vessel 2a is charged with a chemical 1 such as a fumigant, and the lower part of an igniting composition 5 is embedded into said chemical 1. The objective ignition device is comprised of a match tip chemical 3 and a slide member 4a for rubbing said tip chemical 3. For said tip chemical 3, its base end is in contact with said composition 5, and the slide member 4a, which is made of an elastic material with part of the facing inner surface in a narrow space provided with a match side chemical layer 8, is set to so as to sandwich said tip chemical 3 with said facing inner surface. When the slide member 4a is put to reciprocating motion, the match tip 3 is rubbed. Said match tip 3 and slide member 4a may be covered with a light-transmissive cover or a cover with aperture capable of confirming ignition.

摘要： PURPOSE: To reduce manufacturing cost by forming a container from a nonwoven cloth coated with one or more kinds of cement admixtures selected from water reducing agents, early strengthening agents, accelerators, retardants and fluidizing agents and housing a cement mixture. CONSTITUTION: A container 2 is formed from a nonwoven cloth coated with a cement admixture as an anchor bolt settling capsule 1 and a cementitious mixture 3 is housed therein. The container 2 uses a material having a high water permeability and a specified strength even after penetration of water, and both the inner and outer surfaces of the container 2 are coated, meeting the purpose, with one or more kinds of cement admixtures selected among water reducing agents, early strengthening agents, accelerators, retardants, fluidizing agents, etc. This constitution reduces the hardening characteristics variation and a high reliability can be obtained.

摘要： PURPOSE:To permit tensioning members to be drawn out readily by a method in which a grout is powdered by hydration or vibration by using an expandible grout. CONSTITUTION:An expandible grout 5 composed primarily of quick lime is injected into an anchor hole 2, and a tensioning member 1 is inserted into the hole 2 to fix the member 1 by the expansion pressure of the grout 5. When the anchor becomes unnecessary, water is added to or vibration is applied to the grout 5 to crush the grout into powder. The tensioning member 1 can thus be easily removed away by very small pulling forces.

摘要： PURPOSE:To obtain the connection part of metallic pipe of high reliability with simple method by forming an exothermic agent with setting to the shape of the connection part of a tubular material and by fitting to the connection part with the state of setting up the brazing material to the inner part of the exothermic agent and by burning it with igniting. CONSTITUTION:A heater 1 is formed by solidifying with forming in cylindrical shape the self-exothermic agent having a thermit reaction function and the inner diameter of cavity parts 3, 4 is set to the outer diameter of tubular materials 6, 7 and joint 8. The brazing material 5 of semiannular shape is fixed on the step part 2 of the heater 1 and the end part of the joint 8 being fitted to the tubular materials 6, 7 to be connected is positioned so as to about the brazing material 5. The brazing is performed by melting the brazing material 5 with igniting the heater 1 and by pouring it into the gap of the overlapped part of the tubular materials 6, 7 and joint 8. The metallic pipe connection part of high reliability is thus obtd. with a simple method.
