发明名称 Method of achieving noise control and noise controlled system
摘要 <p>Described herein is a method and apparatus for achieving optimum noise control of multiple coronode wires (71, 72) in a copier/printer involves optimizing phase relationships of the voltage on the wires (71, 72) in such a way so as to steer the maximum part of the noise distribution profile in the direction best suited for absorption or dissipation. In a two corotron charging system, the coronode wires (71, 72) are connected to respective power supplies (90, 91) which are controlled by a phase controller (77). The wires (71, 72) are preferably charged such that the phase angle, charge frequency and spacing between wires (71, 72) are optimized. &lt;IMAGE&gt;</p>
