The time targeted for measurement.
Electrostatic energy discharged from a charged object through a conductive object in close proximity.
Discharging brushes utilize this principle.
A type of light irradiation ionizer. The ionizer uses soft X-rays, a type of electromagnetic wave with an
extremely short wavelength.
Brush-shaped self-discharging devices commonly equipped with OA equipment (such as at the paper
outlet on copy machines). These do not require power supplies, as they remove charges by grounded
conductive fiber as electrodes. Although low-priced and simple to attach, their theoretical charge
removal capacity is greatly affected by the potential of the charged object and they therefore cannot
perform charge removal when the amount of charge is low (approx. 3 kV or less).
In ionizers, such characteristics as static charge removing time, static charge removing range, ion
balance, etc.
The time required for reduction from a certain voltage down to a specified voltage. Also called
electrostatic decay time.
Electricity where the charge’s spatial movement is very small.
An ionizer. Also called a static charge removal device. (See Ionizer.)
A metallic element, with the element symbol W. It has the highest melting point of the metals, and
because it possesses an electrical resistance that is relatively high for a metal, it is used as a filament
for incandescent bulbs, etc. It is often used for ionizer discharging needles.
A type of light irradiation ionizer. It features ultraviolet, a type of electromagnetic wave with a
wavelength longer than soft X-rays, and uses the optoelectric effect to ionize the atmosphere.
