摘要： A single piezoelectric is excited at a first frequency to cause two vibration modes in a resonator producing a first elliptical motion in a first direction at a selected contacting portion of the resonator that is placed in frictional engagement with a driven element to move the driven element in a first direction. A second frequency excites the same piezoelectric to cause two vibration modes of the resonator producing a second elliptical motion in a second direction at the selected contacting portion to move the driven element in a second direction. The piezoelectric is preloaded in compression by the resonator. Walls of the resonator are stressed past their yield point to maintain the preload. Specially shaped ends on the piezoelectric help preloading. The piezoelectric can send or receive vibratory signals through the driven element to or from sensors to determine the position of the driven element relative to the piezoelectric element or resonator. Conversely, the piezoelectric element can receive vibration or electrical signals passed through the driven element to determine the position of the driven element. The resonator is resiliently urged against the driven element, or vice versa. Plural resonators can drive common driven elements.

摘要： A piezoelectric apparatus comprising a piezoelectric element that is held in static compression is manufactured using moldable materials and a molding process, e.g., injection molding or die casting. The static compression is caused by an intrinsic urge of the moldable material to expand, contract, or deform otherwise, which develops in the material during the hardening phase of the molding process. To enhance the usefulness of the device, a variety of inserts can be connected to the device and various features can be formed by the moldable material at the same time as the molding process takes place. Static preloads may also be caused by mechanically preloaded elements that are introduced during the molding process or by elements that concurrently introduced but that are permanently deformed thereafter.
摘要翻译：包括保持静止压缩的压电元件的压电装置使用可模制材料和模制工艺（例如注模或压铸）制造。静态压缩是由于可模制材料在模制过程的硬化阶段期间在材料中产生的膨胀，收缩或变形的内在冲动引起的。为了提高装置的有用性，可以将各种插入件连接到装置，并且可以在模制过程发生的同时由可模制材料形成各种特征。静态预载荷也可能由在模制过程中引入的机械预加载元件或同时引入但在其后永久变形的元素引起。
