Abstract: PURPOSE:To prevent a hydrocarbon of a foaming agent from being exploded, since even if static electricity which is apt to be generated by progressing the foaming of a foamed heat insulation material is led outside, by a method wherein a wall surface of an inner box comprised of a synthetic resin on the foamed heat insulation material side is made into the same electric potential as that of an outer box by applying a conductive coating to the wall surface. CONSTITUTION:A heat insulation box body 1 of a refrigerator is formed of a metallic outer box 2, an inner box 3 made of a synthetic resin and a foamed heat insulation material 4 wherein a hydrocarbon filled into a space between both the boxes 2, 3 is taken as a foaming agent. In the outer box 2, a double flange 5 is formed on a front edge of an opening, in which an outward flange 6 formed on the front edge of the opening of the inner box 3 is inserted. A conductive coating 7 is applied to the surface of a foamed heat insulation material side of the inner box 3. The conductive coating 7 is positioned at the flange also, joined electrically to the double flange 5 of the outer box 2 and formed into the same electric potential as that of the outer box 2. Hereby, it becomes earthable easily through the outer box 2. Such a hazard that the circumference is destroyed by an explosion of a foaming agent during a foaming operation of a heat insulation material is eliminated.

Abstract: PURPOSE:To produce safely without having hazards of an explosion and fire in a foaming process, by providing a communicating port for setting an evaporated hydrocarbon streamed out through a heat insulation box body free out of a jig is provided in the jig. CONSTITUTION:A foaming jig is constituted of an outer jig 5 and inner jig 6. The outer jig 5 makes a circumferential frame 5a covering the circumference of an outer box 8 and a top frame 5b movable by a hinge. A vent hole 10 comprised of a small hole is formed in the rear 8a of the outer box 8 also and a communication port 7 and the vent hole 10 become coincident with each other. An evaporated hydrocarbon streamed through the vent hole 10 provided in the outer box 8 can be set free to the outside through the communication port 7. Consequently, even if a foamed heat insulation material 11 for which such a substance that has explosive properties is used as a foaming agent, dwelling of the evaporated hydrocarbon between the outer jig 5 and inner jig 6 is eliminated.

Abstract: PURPOSE:To eliminate the danger of explosion or a fire in a urethane foaming process and thereby to enable execution of safe production by providing a process of eliminating static electricity of a jig for foaming, an inner jig, a workpiece, etc., before injection of urethane in urethane foaming equipment using hydrocarbon as a foaming agent. CONSTITUTION:A process of eliminating static electricity is executed by a foaming jig of a heat-insulating box which is formed by a bottom jig 9 a part of which is grounded, by an inner jig 10 being in contact with the bottom jig 9 and by a top jig 11 of synthetic resin and lateral jigs 12 of synthetic resin which surround the inner jig 10. A static electricity eliminator 13 of a voltage impression type generates ions 14 and thereby eliminates electric charges generated in the inner jig 10, the top jig 11 and the lateral jigs 12 made of the synthetic resin and being nonconductors. Even when an explosive substance, hydrocarbon such as pentane or cyclopentane, is used as a foaming agent in a posterior process, as the result, the static electricity is hardly generated in the advance of foaming and the danger that the foaming agent explodes in the course of a heat-insulative foaming operation and destructs the surroundings is eliminated.

Abstract: PROBLEM TO BE SOLVED: To make reducible the production lead time and development lead time by reducing the integrated formation type preprocessing process of a complicated part forming a meander-shaped commodity path being an obstacle to consistent line production from material to assembly for a commodity housing device for an automatic vending machine. SOLUTION: This commodity housing device forms a commodity path 27 which heaps and houses commodities in a vertically meandering manner between the left and right side boards 28a and 28b erecting in an opposite way with facing path formation plates 29 provided so as to make intervals almost constant. The plates 29 form a meander cross section shape in which small curved parts 29a and large curved parts 29b alternately are arranged in a vertical manner so as to make the intervals almost constant. The meander cross section shape is formed by pressing the plates 29 to be bent in an assembly stage, and the plates 29 are made to engage between the left and right side boards 28a and 28b.

Abstract: PURPOSE:To ensure that an object consisting of a non-conductive element is not susceptive of explosion due to static electricity or fire due to ignition to avoid a danger as the surface of the object becomes easily earthed due to an increase in electroconductivity by filling an explosion-proof chamber maintained higher than a specified level of relative humidity with a raw material such as a foaming agent. CONSTITUTION:A space between paired walls 2 covered with a fixture 4 is filled with a raw material for a foamed heat insulating material such as hydrocarbon or polyol. After the supply of the raw material, foaming develops and hydrocarbon leaking from the fixture 4 following the foaming is exhausted. This foamed resin is cured and paired walls 2 are obtained. An explosition-proof chamber 13 is equipped with a suction air blower 14 and an exhaustion air blower 15, and is heated through an electric heater 16. In addition, an object in the explosition-proof chamber 13 is earthed. Further, the relative humidity of the chamber is maintained higher than 65% using a humidity adjuster installed at the chamber 13. Thus the surface of the object becomes electroconductive more highly so that it is more susceptible of earthing.

Abstract: PURPOSE:To prevent static electricity from being generated, by a method wherein a metal containing resin of a conductive material is used for a wall surface of an inner jig comprised of a synthetic resin and the wall surface is made to have the same electric potential as that of an inner box part comprised of the synthetic resin of a heat insulation box body. CONSTITUTION:A heat insulation box body A is formed of an inner box 7 which is made of a synthetic resin and provided with an outward flange 7a on the front end, an outer box which is made of a metal and provided with an inward flange 8a abutting against the flange 7a of the inner box 7 on the front end and a foaming heat insulation material 9 which takes an inflammable hydrocarbon such as pentane or cyclopentane as a foaming agent between wall surfaces of both the boxes 7, 8. Hereby, even if static electricity is generated between the inner jig 3 for wall surface of which a conductive material 3a is used and the inner box 7 comprised of the synthetic resin, earth becomes easy to take. Consequently, safe foamed jig wherein such a hazard that the circumference is damaged by explosion of the foaming agent during foaming of the heat insulation material is eliminated is obtained.

Abstract: PURPOSE:To reduce the number of component parts and simplify a manufacturing procedure by a method wherein a plurality of steel plates are overlapped on each other, an opening is left at the outer-most circumference of the steel plate, an entire circumference of the steel plate is welded and then adequate fluid is added from the opening, an expanded part is formed through a pressurization and formation and then a gas blowing hole is opened at the expanded part at its proper position. CONSTITUTION:At first, two stainless steel plates 21 are overlapped on each other while they are not formed. An inner-most circumference 22 and an outer-most circumference 23 are welded by TIG welding which is a kind of arc welding with an opening 24 being left at an outer-most circumference 23 of the stainless steel plate 21. After the stainless steel plate 21 is fixed to forming dies 29 and 30, proper fluid such as water, oil, solvent and air is forcedly inputted from the opening 24 with a proper pressure. An expanding part 26 is formed along grooves 31 and 32 formed in the forming dies 29 and 30, a gas accumulation part 27 is formed so as to make a combustion device 20 having a gas blowing hole 25 at a proper position in the expanding part 26. In this way, it is possible to eliminate a cutting process, simplify a manufacturing procedure and then a less-expansive combustion device with high productivity can be manufactured.
