    • A method for assembling a printhead such as an ink jet printhead can include the use of an ultrasonic bonding process to bond two or more printhead layers together. In an embodiment, an ultrasonic frequency is directed to an interface between a first layer and a second layer to generate heat at the interface. In an embodiment, the heat melts at least one of the first layer and the second layer, and the layers are cooled to cure the melted layer. In another embodiment, the heat generated using the ultrasonic frequency cures an adhesive layer between the first layer and the second layer. The ultrasonic lamination process described can result in a fluid-tight seal which requires less processing time and materials over an adhesive-based process.
    • 用于组装诸如喷墨打印头的打印头的方法可以包括使用超声波接合工艺将两个或更多个打印头层粘合在一起。 在一个实施例中,超声波频率被引导到第一层和第二层之间的界面,以在界面处产生热量。 在一个实施例中,热量熔化第一层和第二层中的至少一层,并且将层冷却以固化熔融层。 在另一个实施例中,使用超声频率产生的热量固化在第一层和第二层之间的粘合剂层。 所描述的超声波层压方法可以产生流体密封,其在基于粘合剂的方法上需要较少的处理时间和材料。

    • The present application is directed to novel electrostatic actuators and methods of making the electrostatic actuators. In one embodiment, the electrostatic actuator comprises a substrate, an electrode formed on the substrate and a deflectable member positioned in proximity to the electrode so as to provide a gap between the electrode and the deflectable member. The deflectable member is anchored on the substrate via one or more anchors. The gap comprises at least one first region having a first gap height positioned near the one or more anchors and at least one second region having a second gap height positioned farther from the anchors than the first region. The first gap height is smaller than the second gap height.
    • 本申请涉及新型静电致动器和制造静电致动器的方法。 在一个实施例中,静电致动器包括衬底,形成在衬底上的电极和位于电极附近的可偏转构件,以便在电极和可偏转构件之间提供间隙。 可偏转构件经由一个或多个锚固件锚定在基底上。 所述间隙包括至少一个第一区域,其具有位于所述一个或多个锚固件附近的第一间隙高度和至少一个第二区域,所述第二区域具有比所述第一区域更远离所述锚定件的第二间隙高度。 第一间隙高度小于第二间隙高度。
