Abstract: A static eliminator that can be placed at a close distance capable of eliminating static electricity while preventing furious elevation of the surface electric potential of a work when the static eliminator is placed at a close distance to the work. A cover formed by an electro conductive porous material covering discharge needles is attached to a holding member in which a plurality of the discharge needles are provided and air blowing openings for ejecting air around the discharge needles are provided. The cover evenly discharges ionized air from the surface of the cover, and is electrically connected to ground to have a function for absorbing a part of generated ions.

Abstract: To provide an ionizer wherein an air flow path in a hollow casing is formed so as to be pressure-resistant while ensuring an effective cross sectional area without becoming voluminous, and the flow path is ensured simply and easily. In an ionizer including a hollow casing that contains a high voltage power unit and a control unit inside, along the longitudinal direction of the casing, a plurality of electrode units each including needle electrodes and an air outlet for blowing out an air stream around the needle electrodes are arranged in a line. A part along the longitudinal direction of the hollow casing is formed of a synthetic resin, and a resin casing composed of the synthetic resin is integrally formed with a conduit of an air flow path extending in the longitudinal direction of the casing so that a part of the inner wall of the resin casing serves as a wall of the conduit and that the air flow path communicates with the air outlet.

Abstract: To provide a static eliminating method and apparatus therefor which applies a high voltage to one of a pair of electrode needles and earths the other thereof, and eliminates the need of an earthed ground plate. A single or several electrodes are provided, having one pair of electrode needles for individually applying positive and negative high voltages facing each other in a holding member made of insulating material.
