JP2000323296A - Charge neutralization device of static electricity on vacuum layer and its manufacture - Google Patents

Abstract

PROBLEM TO BE SOLVED: To enable charge neutralization without using an extremely thin discharge electrode of a self-discharging type charge neutralizing device by installing an intermediate part of a high tension wire from a high tension power supply of a high tension application charge neutralizing device and a discharge electrode provided in its top, or a high tension application charge neutralization device body and a discharge electrode in a vacuum layer. SOLUTION: Positive and negative DC currents generated independently by stepping-up of a piezoelectric transformer of a high tension power supply 1 are made to flow to a high tension wire 3 via a high resistance resistor 2 as necessary. A positive electrode discharge electrode 4, which is provided at the tip of the wire 3 and has a linear needle tip prevented from being bent by impact, and the intermediate part of the high tension wire 3 are installed in a vacuum layer 6. Electrons generated thereby move to the positive electrode discharge electrode 4 to lower the voltage of negative electrification on a film 7 in the vacuum layer 6 and the voltage is made zero eventually. The negative electrode discharge electrode may be installed in the vacuum layer 6 at a prescribed distance apart from the positive electrode discharge electrode 4. The electrification on the film 7 or the like is eliminated by being involved in the movement of the electrons toward the positive electrode discharge electrode 4.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION In the present invention, various kinds of disasters occur in a target object due to electrostatic charging in the action in a vacuum layer. The present invention relates to a device for removing the charge and a method for manufacturing a static eliminator used for the device.

[0002]

2. Description of the Related Art Conventionally, static elimination in a vacuum layer has been carried out by using a self-discharge type static eliminator. However, a static eliminator with a high voltage has not been implemented yet.

[0003]

In the conventional self-discharge static eliminator, since there is no buffer in the vacuum layer due to air, a part of the ultra-fine discharge electrode of the self-discharge static eliminator is broken and adheres to a film or the like. There was a problem.

In the conventional self-discharge static eliminator, since there is no buffer in the vacuum layer due to air, a part of the very fine discharge electrode of the self-discharge static eliminator is bent by the impact of static elimination, and the static elimination effect is significantly reduced. There was a problem.

An object of the present invention is to provide a static elimination method capable of eliminating static without using a very thin discharge electrode of a self-discharge type static eliminator.

[0006]

In order to achieve the above-mentioned object, in the static eliminator of the present invention, a high-voltage power supply type static eliminator is installed at an intermediate portion of a high-voltage electric wire from a high-voltage power supply and at an end thereof. It is an object of the present invention to install a certain discharge electrode in a vacuum layer or to install a high voltage application type static eliminator body and a discharge electrode in a vacuum layer.

In order to remove electricity in the air, the air is ionized by the energy discharged from the needle tip, which is a discharge electrode, and the ions are removed by this ion. In a vacuum, however, electrons are transferred from the charged body to the discharge electrode. The charge of the charged body is removed by the movement of the charge.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment will be described with reference to the drawings. As a high-voltage power supply 1, a piezoelectric transformer is boosted to generate DC + and + separately, and a high resistor 2 is inserted as required. The intermediate portion of the high-voltage electric wire 3 is inserted into the vacuum layer 6, and at the tip of the high-voltage electric wire 3, any one of a positive electrode discharge electrode, a linear discharge electrode, and the like is installed as the positive electrode discharge electrode 4.

In the vacuum layer 6, both the middle portion of the high-voltage wire 3 and the positive electrode 4, the middle portion of the high-voltage wire 3, and the minus electrode 5 are installed.

[0010]

Since the present invention is configured as described above, it has the following effects.

The film 7 in the vacuum layer is almost negatively charged. Since the negative portion of the high-voltage electric wire 3 and the positive electrode 4 are disposed in the vacuum layer 6, the electrons generated by the negative charging of the film 7 move to the positive electrode 4, and the negative electrode of the film 7 moves. After the charging voltage drops, the charging voltage becomes zero and the charge is eliminated. The positive electrode 4 and the negative electrode 4
When the electrode 5 and the electrode 5 are arranged at a fixed interval, electrons move from the electrode 5 to the electrode 6. The charge of the film 7 or the like, which is a charged body in the vicinity, was attracted by the movement of the electrons, and the charge of the film 7 disappeared and the charge was removed. The charge elimination in the vacuum layer is charge elimination due to the movement of electrons.
