摘要： PURPOSE:To simplify the construction by elevationally polarizing an annular vibration element, providing electrodes equally divided into four or more on the upper and lower directions, and engaging a slider with the oblique surface of a drive ring. CONSTITUTION:An annular vibrator 1 is made of ceramic electrostrictive element, and polarized elevationally to form four or more (8 in the drawings) equally divided electrodes 3 on the lower surface. Inner and outer oblique surfaces 4, 5 having equal oblique angles are formed on an earth side electrode 3 of the upper surface, and bonded with a drive ring 6 of isosceles triangular shape of section. A disk-shaped slider 7 having an interlocking surface 8a planely contacted with the inner oblique surface 4 is placed on the ring 6. Thus, alternating voltage (Vsinomegat) displaced in timing phase of 2pi/x (x is the number of division) is applied to the electrode 3 to obtain the excitation of traveling wave to rotate the slider 7.
摘要翻译：目的：为了简化通过使环形振动元件垂直偏振的结构，提供在上下方向上等分成四个或更多个的电极，并且将滑块与驱动环的倾斜表面接合。构成：环形振动器1由陶瓷电致伸缩元件制成，并且在垂直方向偏振以在下表面上形成四个或更多个（图中为8）等分电极3。在上表面的接地侧电极3上形成具有相等倾斜角的内外倾斜面4,5，并与等腰三角形状的驱动环6接合。具有与内斜面4平面接触的互锁面8a的盘状滑块7放置在环6上。因此，在2pi / x（x为分割数）的定时相位移位的交流电压（Vsinomegat）为施加到电极3以获得行波的激发以旋转滑块7。
