INK EJECTION TYPE WRITING SYSTEM USING AMPLITUDE-MODULATED ELECTRIC SIGNALS |
摘要 |
<p>An ink ejection system of the invention includes an electrical circuit generating sinusoidal wave pulses and a liquid applying unit operable to discharge the liquid in pulsed jets in response to the sinusoidal wave pulses. The circuit comprises means for generating a sinusoidal signal of constant amplitude and frequency higher than the highest instantaneous frequency of a video signal, and means for modulating the amplitude of the sinusoidal signal in accordance with the video signal to generate a signal containing no harmonic components.</p> |
