Abstract: A purifying agent or the like which can improve purifying performance is obtained. A container (12) of a purifying agent generating apparatus (10) contains a solution (14), into which a surface-active agent has been dissolved, and ozone gas is supplied thereto. In this way, a purifying agent (34) (i.e., aggregate of ozone-containing bubbles (32), each of which includes an ozone-containing membrane, into which ozone has been dissolved, and ozone-containing gas, which is contained in the inner portion of the membrane and includes ozone) is generated. Therefore, odor which fills a sealed space can be removed and a higher purifying performance is obtained.

Abstract: A technologically advanced portable toilet has a purifying agent producing/supplying device built into a periphery of a toilet bowl. Due to an ozone producing mechanism, a tank assembly, and a bubble generating tank, which are provided by this purifying agent producing/supplying device, when an upper cover of the toilet is opened, a purifying agent that is an aggregate of ozone-containing bubbles is supplied to an inside of the toilet bowl. As a result, a superior odor-extinguishing effect can be obtained.

Abstract: A waste disposal apparatus in which a container main body includes an introduction opening at a top wall portion of the container main body and a discharge opening at a bottom wall portion of the container main body. A cylindrical body having an exit portion is disposed within the container main body and is formed of an elastic material. An exit portion opening/closing device selectively holds the exit portion between a closed state, in which an exit portion of the cylindrical body is pressed and sealed, and an opened state, in which the exit portion of the cylindrical body is opened and the waste accumulated within the cylindrical body is discharged. The exit portion opening/closing device includes exit portion protruding device which, at the time of dumping of the waste, protrudes the exit portion of the cylindrical body to below the bottom wall portion of the container main body and through the discharge opening thereof.

Abstract: An apparatus for separating piled iron sheets one by one has a plurality of magnets arranged vertically with the same magnetic poles thereof facing each other. Magnetic fluxes generated from the magnets react with each other at a position between the magnets and flow horizontally and then vertically, with the result that opposite, vertically separating forces act on two superposed iron sheets.

Abstract: An automatic seam welding apparatus for fuel tanks comprises a jig for holding two workpieces disposed one above the other to form a fuel tank, a pair of roller electrodes vertically arranged for nipping and welding the overlapping peripheral flange portion of the workpieces, and a robot assembly rotatably supporting the jig and controlling the horizontal and vertical positions and the inclination of the jig held workpieces relative to the electrodes for welding peripheral flange portions that are irregular with high quality welds. The jig is easily detachable from the robot to permit many different shaped tanks to be welded by the same apparatus.

Abstract: A movable yoke-type lifting magnet device including a core having first and second ends and at least one yoke provided so as to be movable relative to the core in a vertical direction at each of the first and second ends of the core. A movable framework and a drive member for driving the movable framework relative to the core are further provided for lifting and lowering each yoke relative to the core. When the movable framework is driven upwards, the movable framework engages with each yoke and forcibly lifts each yoke. When the movable framework is driven downwards, the movable framework releases the yokes to allow them to move downwards by their own weight and to be gently brought into contact with a workpiece to be lifted.

Abstract: A movable yoke-type lifting magnet device including a main core wound with a coil and at least one yoke magnetically coupled to the core. The movable mechanism of the yoke enables the yoke to freely follow the contour of a workpiece to be lifted. An auxiliary core may be provided between each said at least one yoke to provide a yoke-type lifting magnet device. The auxiliary core greatly increases the magnetic forces induced between the cores and the yoke. Combination of the magnetic coupling between the yokes and the core and the provision of the auxiliary core provides a movable yoke-type lifitng magnet device wherein the yoke can freely follow the contour of a workpiece and the magnetic forces between the cores and the yoke are greatly increased. Such a combination prevents the yoke from slipping relative to the cores and stable lifting is possible.

Abstract: An apparatus for carrying a workpiece to and out of a press is provided with at least a pair of workpiece carrying mechanism assemblies which are driven and controlled independently, and each of the mechanism assemblies includes at least one attachment for attracting the workpiece.

Abstract: A method and apparatus are provided for removing spatter from a torch of a gas shielded arc welding apparatus. After a series of welding operations are completed, pressurized air mixed with a small amount of oil is injected through a passage defined between a member supplying a welding electrode and a gas nozzle. This oil emitted adheres to the surface of the electrode supply member and the gas nozzle, thereby generating an oil film thereon. The pressurized air removes any spatter on the apparatus and the oil film prevents any further spatter from adhering to the surface.

Abstract: The resistance welding machine of this invention has an arm carrying a movable electrode and provided with a supporting bore, a power receiving bushing fitted in the supporting bore, and a power feeding shaft mounted on the main body of the welding machine on which a second electrode, is also mounted. The power feeding shaft is received by the bore of the power receiving bush to support the arm while supplying electric power to the movable electrode. A plurality of grooves are formed in the inner peripheral surface of the power receiving bushing to receive powders generated as a result of local wear due to sliding contact between the power feeding shaft and the power receiving bushing. The grooves are filled with grease which adsorbs and holds the powders.

Abstract: In effecting resistance welding, fluid pressure is applied to a piston in a cylinder to drive the piston rod ahead so that work being welded is clamped between an electrode provided at the end of the rod and another electrode carried by an arm to apply a suitable welding pressure to the work. As the piston is further moved ahead, a collector ring is expanded radially outwardly to make electrical contact with the power feeding liner, so that welding current fed from a feeder cable is supplied to the electrode through the cylinder, feeding liner, collector ring, collector plate and the rod, thereby to effect the welding while applying a suitable pressure to the work.
