20080252179 | Piezoelectric Element and Method for Manufacturing the Piezoelectric Element - A piezoelectric element includes a piezoelectric ceramic body containing an internal electrode. The piezoelectric ceramic body is mainly made of a perovskite complex oxide containing an alkali metal niobate-based compound containing at least one element selected from among K, Li, and Na. The internal electrode is made of a base metal material, such as Ni or Cu. The piezoelectric element is produced by co-sintering the internal electrode and the piezoelectric ceramic body. Thus, there is provided an inexpensive piezoelectric element that can be properly used in practice even though it has been fired in a reducing atmosphere. | 10-16-2008 |
20080284284 | RESONANT ACTUATOR - A resonant actuator includes a driving unit having a displacement element that vibrates at a resonance frequency or in a frequency range in the vicinity of a resonance frequency and having a driven member that is driven by the displacement element, in which the displacement element has a piezoelectric ceramic body made of a bismuth layered compound. The displacement direction of the displacement element is preferably substantially the same as the direction of polarization of the piezoelectric ceramic body. The bismuth layered compound is preferably oriented such that the direction of the c crystallographic axis is substantially perpendicular to the direction of polarization of the piezoelectric ceramic body. More preferably, the degree of c-axis orientation is determined to be at least about 75% by the Lotgering method. Thereby, it is possible to provide a resonant actuator having a large saturated vibration velocity, minimizing reductions in the resonance frequency fr and the mechanical quality factor Qm without the destabilization of the vibration velocity even at a high vibration velocity, and having a large amount of displacement even at a high electric field. | 11-20-2008 |
