摘要： A stacked piezoelectric device and a method of fabrication thereof includes a piezoelectric stack having a first side electrode and a second side electrode, piezoelectric layers and internal electrode layers. The piezoelectric layers and internal electrode layers have substantially the same area. The internal electrode layers have ends thereof exposed to one side of the stack. The first side electrode includes first insulative portions formed at the ends of alternate ones of the internal electrode layers and a first conductive portion formed over the first insulative portions. The second side electrode is similarly configured to form insulative portions at the other ends. The first and second insulative portions are formed of an insulative resin, while the first and second conductive portions are formed of a conductive resin. The first and second conductive portions are also formed to directly cover the ends of the internal electrode layers.

摘要： For superfinishing an elongate cutting tool which has been rough-ground by a separate machine, a pair of grinding wheels are first urged against the opposite sides of the work via respective fluid-actuated cylinders, until sufficient fluid energy builds up in the cylinders to enable the grinding wheels to grind the work to any desired depths. Being mounted on a common carriage, the grinding wheels are then reciprocated longitudinally of the work while being held in constant rotation and being urged against the work under the fluid pressure. On reaching either end of the work during such reciprocation, the grinding wheels are relieved of the fluid pressure until they restart traveling toward the other end, in order to avoid overgrinding the opposite ends of the work. The reciprocation of the grinding wheels is terminated when the opposite sides of the work are ground to required degrees. The complete operation can be automated. Preferably, one of the grinding wheels is angularly displaceable relative to the work about an axis parallel to the longitudinal direction of the work.

摘要翻译： 对于通过单独的机器进行粗磨的细长切割工具，首先通过相应的流体致动圆柱体将一对研磨轮推压到工件的相对侧上，直到足够的流体能量积聚在气缸中以使得 磨轮将工件磨削到任何所需的深度。 安装在公共的托架上，砂轮随后在工件的纵向往复运动，同时保持恒定的旋转并且在流体压力下被推动抵抗工作。 在这种往复运动期间到达工作的任一端时，磨轮减轻流体压力，直到它们重新开始朝向另一端运动，以避免过度研磨工件的相对端。 当工件的相对侧被磨削到所需的角度时，磨轮的往复运动被终止。 完整的操作可以自动化。 优选地，一个砂轮相对于工件围绕平行于工件的纵向的轴线成角度地移位。

摘要： To provide a stacked piezoelectric device which is inexpensive and excellent in bonding strength between a piezoelectric layer and an internal electrode layer, the piezoelectric device comprises piezoelectric layers and internal electrode layers containing not less than 50 percent by weight of Cu stacked alternately. Between the internal electrode layer and the piezoelectric layer, there is a diffusion region formed by mutual diffusion of components of the internal electrode layer and the piezoelectric layer to the other layer and comprising at least one component of the piezoelectric material and Cu. The diffusion region occupies not less than 90 percent of area of interface between the internal electrode layer and the piezoelectric layer, and a thickness of the diffusion region is not more than 10 percent of a thickness of the internal electrode layer. A piezoelectric material constituting the piezoelectric layer preferably comprises PZT which is a Pb(Zr,Ti)O3— based oxide having a perovskite structure, and Pb, Cu, and O elements coexist in the diffusion region.
