摘要： The invention relates to a piezoactuator (1) comprising a piezoelectric body (4) and elements for pre-tensioning the piezoelectric body, consisting of a first (2) and a second (3) connecting element for transferring forces to the piezoelectric body (4). The actuator is provided with an element (6) for transferring tensile/pressure forces between the connecting elements (2, 3), said element being at least partially located in a gap (5) in the form of a bore in the piezoelectric body (4). According to the invention, the piezoactuator (1) is set to a defined working curve using the pre-tensioning elements (2, 3, 6). The piezoelectric body (4) is preferably produced by the lamination of piezoelectric layers, into which a gap is drilled after lamination and the component is subsequently sintered.

摘要： A laminated piezoelectric element is applicable as a driving source of opening and closing mechanism of an injection nozzle in a fuel injecting device. A laminated piezoelectric/electrostrictive element 1 has: a columnar laminate 10 constituted by alternately laminating a plurality of piezoelectric/electrostrictive layers 14 and inner electrode layers 18, 19; and outer electrodes connected to the inner electrode layers 18, 19 every other layer. This laminated piezoelectric/electrostrictive element 1 has stepped portions A formed periodically at every laminating cycle T in a side surface of the columnar laminate 10 of the element, the side surface being parallel to an axial direction (S-direction) of the columnar laminate 10. Due to the constitution mentioned above, the electrode is not easily worn even during an expanding and contracting operation during practical use, and the element can sufficiently circulate and cool a lubricant through the casing even during practical use.

摘要： The invention relates to a fully active piezoelectric actuator (90) and to a method for producing a fully active piezoelectric actuator (90). A fully active piezoelectric stack (1) is first of all provided, which stack has alternately successive piezoelectric layers (2) and inner electrodes which pass through to the outer side (5, 6) of the piezoelectric stack (1) and each have a first region (31), which does not adhere or adheres poorly to a coating, and a second region (32) which adheres well to the coating. The inner electrodes are provided for the purpose of using their first regions (31) to alternately contact-connect a first outer electrode (10) and a second outer electrode (11) of the piezoelectric actuator (90). The outer side (5, 6) of the fully active piezoelectric stack (1) is coated with the coating at least in regions which are assigned the outer electrodes (10, 11) of the piezoelectric actuator (90). The coating (70) is then removed in regions which border the first regions (31) of the inner electrodes and the two outer electrodes (10, 11) are applied to the remaining coating (80), with the result that the outer electrodes (10, 11) contact-connect the first regions (31) of the inner electrodes and the coating (80) is otherwise arranged between the inner electrodes and the outer electrodes (10, 11).

摘要： Amultilayer piezoelectric actuator and a liquid discharge head are provided which are equipped with dense piezoelectric ceramics having improved insulation performance. The multilayer piezoelectric actuator comprises a multilayered body comprising a plurality of piezoelectric ceramic layers containing a PZT phase as a main crystal phase; and an electrode layer containing Ag, which is disposed at least one of on the surface and in the interior of the multilayered body. A lattice constant c of c-axis of the PZT phase is 0.4085 nm to 0.4100 nm, and a ratio of the lattice constant c of the c-axis of the PZT phase and a lattice constant a of a-axis, namely, the ratio c/a, is 1.011 or more. A second phase containing Ag different from the PZT phase is not substantially contained in the piezoelectric ceramic layer. A Zn 2 SiO 4 phase is contained at grain boundaries of the PZT phase, and a Pb 2 SiO 4 phase is not substantially contained at the grain boundaries of the PZT phase.

摘要： In a piezoelectric multilayer actuator (1) having micromechanical relief zones (30) and an insulation layer (40) as well as in a method for producing said actuator, as a result of the micromechanical relief zones (30), poling cracks are concentrated in these relief regions (30). This makes it possible to provide the sections I, II, III of the multilayer actuator (1) with an insulation layer (40) which only has an extension behavior similar to the multilayer actuator (1) without poling cracks.

摘要： In the manufacture of a laminated piezoelectric/electrostrictive element by lamination of a piezoelectric/electrostrictive film and an electrode film containing either platinum or an alloy composed mainly of platinum and having a thickness of 2.0 µm or less, both or either one of yttrium oxide (Y 2 O 3 ) and cerium oxide (CeO 2 ) is added to the electrode film or the piezoelectric/electrostrictive film, and the electrode film and the piezoelectric/electrostrictive film are fired simultaneously. This simultaneously achieves a reduced thickness and improved thermal resistance of the electrode film and a reduced change in piezoelectric/electrostrictive properties with time, thereby producing a piezoelectric/electrostrictive element with good initial piezoelectric/electrostrictive properties and with a small change in the piezoelectric/electrostrictive properties with time.
