Abstract
To perform a corona discharge treatment, a high voltage needs to be impressed between a base electrode and a discharge electrode. One of the electrodes is linked to a high frequency and high voltage source, and the other electrode is grounded. When the electrode linked to the source is moved to be accommodated to a surface to be treated of an object, accidents of an electric shock or a short-circuit often result from an unexpected contact of the electrode on an operator or installation, or a troubles often result from spark or coming-part of contacts. In this invention, one of the electrodes is linked to the source and immovably arranged, while the other is grounded and is allowed to make the movement for accommodating the surface to be treated of the object and the discharge electrode to each other. According to the corona discharge treatment apparatus of this invention, such accidents as an electric shock or a short-circuit, etc., are foreclosed, and troubles are reduced.
