Title:
液滴吐出装置の駆動
Document Type and Number:
Japanese Patent JP2011522717
Kind Code:
A
Abstract:
Methods, systems, and apparatus, for drop ejection, specifically, for driving drop ejectors using n-type double-diffused metal oxide semiconductor (NDMOS) transistors with sputtered piezoelectric transducers. In general, in one aspect, an apparatus includes a n-type double-diffused metal oxide semiconductor transistor. The apparatus also includes a piezoelectric transducer. A first surface of the piezoelectric transducer is coupled to the n-type double-diffused metal oxide semiconductor transistor. The apparatus also includes a first waveform generator configured to generate an ejector waveform to apply to a second surface of the piezoelectric transducer. The ejector waveform includes at least a positive pulse and a negative pulse. The apparatus also includes a second waveform generator configured to generate a control waveform to apply to the n-type double-diffused metal oxide semiconductor transistor to selectively actuate the piezoelectric transducer.
