摘要： A printing head for an ink jet printer is provided with a plurality of ink jet sets. Each of the ink jets. Each of the ink jets includes an ink nozzle through which ink is ejected; a pressure chamber communicated with the ink nozzle and having a diaphragm made of a flexible plate; and a piezoelectric member bonded on an outside of the diaphragm for deforming the diaphragm to eject ink through the ink nozzle from the pressure chamber. The piezoelectric member includes a layer, having titanium an upper PZT layer chemically bonded on an upper surface of the titanium layer and polarized in a first direction; and a lower PZT layer chemically bonded on a lower surface of the titanium layer and polarized in a second direction opposite to the first direction. The titanium layer includes an interconnecting member and titanium members interconnected to each other by the interconnecting member forming a single titanium plate comb having teeth corresponding to the titanium members extending from two sides of the interconnecting member.

摘要翻译： 用于喷墨打印机的打印头设有多个喷墨组。 每个喷墨喷嘴。 每个喷墨喷嘴包括一个墨水喷嘴，墨水通过该墨水喷射; 压力室与墨水喷嘴连通并具有由柔性板制成的隔膜; 以及压电构件，其结合在所述隔膜的外侧，用于使所述隔膜变形，以从所述压力室通过所述墨喷嘴喷射墨。 压电元件包括​​具有钛的上部PZT层化学键合在钛层的上表面上并沿第一方向极化的层; 以及化学键合在钛层的下表面上并沿与第一方向相反的第二方向极化的较低PZT层。 钛层包括互连构件和通过互连构件彼此互连的钛构件，所述互连构件形成具有对应于从互连构件的两侧延伸的钛构件的齿的单个钛板梳。
