    摘要: A piezoelectric actuator is constructed to have a displacement value caused by bending to be added to a usual d31 component displacement, thereby increasing the total amount of displacement of the actuator. The actuator includes an actuator body having a layered structure of piezoelectric layers and internal electrodes, and external electrodes disposed on an external surface of the actuator body at both ends thereof. One of the outermost piezoelectric layers is made piezoelectrically active as a result of making an extension portion of the first external electrode, through the one of the outermost piezoelectric layers, face the inner electrodes, to have a polarity which is different from that of the extension portion, while a second of outermost piezoelectric layers is made piezoelectrically inactive as a result of either making an extension portion of the second external electrode facing, through the second of the outermost piezoelectric layers, the inner electrodes, to have a polarity which is identical to that of the extension portion of the second external electrode or as a result of not forming an extension portion on the outer electrode.

    摘要: A monolithic piezoelectric body includes first internal electrodes which extend to a first side surface of the piezoelectric body but do not extend to a second side surface of the piezoelectric body, and second internal electrodes which extend to the second side surface but do not extend to the first side surface. A connecting internal electrode is disposed within the piezoelectric body and extends between the first and second side surfaces. A first external electrode is disposed on the first side surface and is electrically connected to the first internal electrodes. A second external electrode is arranged on the first side surface so as to be separated from the first external electrode and electrically connected to the connecting internal electrode. A third external electrode is disposed on the second side surface so as to electrically connect the second internal electrodes and the connecting internal electrode.

    摘要: Disclosed is a piezoelectric resonator device. This piezoelectric resonator device comprises a piezoelectric substrate having an almost rectangular plane shape. The piezoelectric substrate is provided with a slit extending to the inside from one edge of the piezoelectric substrate, for forming a tuning fork portion, and a pair of slits for separating the tuning fork portion, spaced apart from the slit forming the tuning fork portion by a predetermined distance on both sides of the slit forming the tuning fork portion, and approximately parallel with the slit forming the tuning fork portion. Vibrating electrodes are formed on both major surfaces of the piezoelectric substrate at a piezoelectric vibrating portion, between the slits separating the tuning fork portion from non-vibrating portions of the substrate.
