Abstract: A tool having switch with support function includes a main body and a switch. The main body extends along an axis. The switch is slidably mounted on the main body and is slidable between an ON position and an OFF position. The switch includes a base slidably connected to the main body. The switch is adapted to stand on a surface stably, and the main body is able to be supported on the surface by the switch. The switch has a supporting structure which projects from the base and extends transversely to the axis. The supporting structure has an abutting end disposed on a first plane which extends transversely to the axis. When the switch stands on the surface, the surface bears the switch from the supporting structure.

Abstract: A method for manufacturing a power capacitor including at least one capacitor element and equipment for carrying out the method. The capacitor element includes a roll of alternate dielectric films and electrode films. The roll has first and second end surfaces facing away from each other. The electrode films are connectably exposed. A solder tip is preheated in a pot with a preheated solder. The solder tip is coated with solder, whereupon at least one of the surfaces of the capacitor element is coated with solder by bringing the solder tip into contact with the end surface. The contact is brought to cease. At least one lead is fixed by soldering to the end surface.

Abstract: A materials heating device includes rod-shaped electrical heating element which serves both to heat a thermoconductive receptacle containing the material to be heated as well as tools and instruments for working with the material. The heating element is mounted in spaced relationship to the receptacle by a thermoconductive bracket through which heat is conducted to the receptacle to heat the contents thereof. The end of the heating element protrudes from the bracket, whereby tools and instruments to be heated can be held in direct contact with the exposed end portion of the heating element until sufficient heat is transferred thereto. An adjustable heat dissipator can be provided on the receptacle to regulate the temperature of the receptacle.
