Ionizer

An ionizer includes a discharge needle, a discharge needle holder holding the discharge needle, and a carrying air jet mechanism jetting out ion-carrying air toward a charge cancellation target. The carrying air jet mechanism is disposed at a position adjacent to the discharge needle holder, and it includes a drive nozzle having a drive air jet port, and a diffuser disposed in front of the drive nozzle with an ambient air suction gap interposed therebetween. A carrying air flow hole is formed inside the diffuser to be coaxial with the drive air jet port, and a carrying air jet port from which the carrying air is jetted out is formed at a fore end of the carrying air flow hole.

An ionizer includes: a positive-side transformer, and a negative-side transformer; a positive-side high-voltage output circuit that has a first input terminal and a second input terminal that are respectively connected to a ground terminal and a power supply terminal, the ground terminal and power supply terminal being provided on the secondary of the positive-side transformer, and also has a first output terminal from which a direct-current positive high voltage is output; a negative-side high-voltage output circuit that has a third input terminal and a fourth input terminal that are respectively connected to a ground terminal and a power supply terminal, the ground terminal and power supply terminal being provided on the secondary of the negative-side transformer, and also has a second output terminal from which a direct-current negative high voltage is output; and a discharge electrode connected to the first output terminal. The ground terminal in the positive-side transformer and the first input terminal in the positive-side high-voltage output circuit are mutually connected through an attenuating capacitor.

The present invention relates to an ionizer, a static charge eliminating system, an ion balance adjusting method, and a workpiece static charge eliminating method. In an ionizer, when positive and negative voltages are applied to an electrode, an amplitude Vm of the negative voltage is set to be smaller than an amplitude Vp of the positive voltage, and further, the time Tm for which the negative voltage is applied to the electrode is set to be longer than the time Tp for which the positive voltage is applied thereto.

Ionizer, static charge eliminating system, ion balance adjusting method, and workpiece static charge eliminating method

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.
