Abstract

PURPOSE: To prevent an insulation breakdown and sputter while lessening discharge tending to concentrate at a narrow gap, by applying a bisa voltage to each electrode.
CONSTITUTION: Since discharge tends to concentrate between electrodes arranged at a narrow interval, electrode G4 with such a gap is supplied with bias voltage 11 so as to reduce a potential difference between adjacent electrodes. Then, it is made possible to apply high voltage 10 as it is between electrodes with the gap and switch 9 is turned ON-OFF to carry out spot knocking. In this case, sparks fly from a part small in potential difference to a large-difference part. The part is therefore cleaned with priority given, so that dielectric-strength characteristics with opposite one can be improved.
