液滴排出装置和用于排出液滴的方法
摘要：
液滴排出装置包括，液滴排出头，其中液滴排出头包括与压力腔连通的喷嘴；第一压电元件，其构造为将液体压入到压力腔中以便引起液滴被排出；和能够将液体压入到压力腔中的第二压电元件；第一驱动波形生成单元，其构造为生成要被施加到第一压电元件的第一驱动波形；第二驱动波形生成单元，其构造为生成要被施加到第二压电元件的第二驱动波形；以及控制单元，其构造为在第一压电元件由于施加的第一驱动波形被驱动之后而施加第二驱动波形到第二压电元件。在压力腔中的液体的残留振动通过由第二压电元件引起的振动被抑制。
摘要（英）：

A droplet ejection apparatus includes, a droplet ejection head, wherein the droplet ejection head includes a nozzle communicated with a pressure chamber, a first piezoelectric element configured to pressure liquid in the pressure chamber so as to cause a droplet to be ejected, and a second piezoelectric element capable of pressuring the liquid in the pressure chamber, a first drive waveform generation unit configured to generate a first drive waveform to be applied to the first piezoelectric element, a second drive waveform generation unit configured to generate a second drive waveform to be applied to the second piezoelectric element, and a control unit configured to apply the second drive waveform to the second piezoelectric element after the first piezoelectric element is driven due to the applied first drive waveform. Residual vibration of the liquid in the pressure chamber is suppressed by a vibration caused by the second piezoelectric element.
