摘要： Disclosed is a water-cooled winding for an electromagnetic stirrer, which comprises a coil including a plurality of wound flat type wires having a wire-insulating turn insulation, and a porous polyamide fiber having an air permeation rate not higher than 25 seconds/100 cm.sup.3 of air covering the periphery of the coil, which is impregnated with an epoxy resin composition. In this water-cooled winding, the polyamide fiber is sufficiently impregnated with the epoxy resin composition and this epoxy resin composition is cured stably and assuredly. Accordingly, the mechanical rigidity of the winding is sufficiently high, and the water resistance of the winding is highly improved and is maintained for a long time, with the result that the life of the winding is greatly prolonged.

摘要： A high-voltage transformer drive circuit and a high-voltage transformer drive discharge tubes. In at least one example embodiment, a tube current synthesis/high pass filter circuit synthesizes tube currents in the discharge tubes, and extracts a pulse component resulting from arc discharge from the synthesis tube current. A pulse hold circuit holds the extracted pulse component for a predetermined time. A comparator compares an output from the pulse hold circuit with a threshold value, and outputs a signal indicating the presence or absence of the arc discharge. Upon detection of the arc discharge, a logic circuit stops the operation of the high-voltage transformer drive circuit. Thus, arc discharge is detected with high accuracy at low cost.
