发明名称 Electrostatic attraction apparatus
摘要 An electrostatic attraction apparatus has circuitry for eliminating electrostatic charge. The circuitry has: (i) a short-circuiting mechanism for short circuiting a pair of conductors; and/or (ii) an impressed polarity-inverting mechanism for inverting the polarity of the DC voltage, or the voltage equivalent thereto, which is applied between the pair of conductors, and which is responsive to termination of the DC voltage applied between the pair of conductors from the voltage-generating means. Thereafter, an attracted body can be detached very easily from an attraction layer irrespective of the relaxation time, that is, the length of time required to extinguish the electrostatic charge.
