摘要： A method of producing a piezoelectric/electrostrictive actuator including preparing first, second and third ceramic green sheets, and laminating the green sheets to form an unfired ceramic body which is then fired. The first, second and third green sheets form spacer, closure, and connecting plates, respectively, the spacer plate having a plurality of windows. An outer surface of the connecting plate that is remote from the spacer plate is machined so as to have a maximum waviness of not larger than 50 .mu.m. Additionally, piezoelectric/electrostrictive elements are formed on an outer surface of the closure plate over respective pressure chambers defined by the windows in the spacer plate.

摘要： A matrix type piezoelectric/electrostrictive (P/E) actuator includes a plurality of piezoelectric/electrostrictive elements, each including a piezoelectric/electrostrictive body and at least one pair of electrodes formed on a ceramic substrate. The matrix type P/E actuator is activated by the displacement of the piezoelectric/electrostrictive bodies. The piezoelectric/electrostrictive elements are joined to the ceramic substrate as respective unified bodies, and are two-dimensionally arranged independently from each other. The piezoelectric/electrostrictive actuator provides a greater displacement with a lower voltage, a high responsive speed, and a greater generating force, as well as enhancing the mounting ability and the integration. A method for manufacturing such a matrix type P/E actuator is also disclosed.

摘要： A ceramic element comprises a main actuator element 26 having an anti-ferroelectric film 22 and a pair of electrodes 24a, 24b formed on a first principal surface (front surface) of the anti-ferroelectric film 22, a vibrating section 18 for supporting the main actuator element 26, and a fixed section 20 for supporting the vibrating section 18 in a vibrating manner. The anti-ferroelectric film 22 after polarization has a region Zt in which its average dielectric constant is increased in an analog manner in accordance with a voltage V applied to the pair of electrodes 24a, 24b. Specifically, an expression of p/t≦2.5 is satisfied provided that an average film thickness of the anti-ferroelectric film 22 is t, and a pitch between the pair of electrodes 24a, 24b is p. Accordingly, the mechanical displacement amount is changed in an analog manner in accordance with the applied voltage, making it possible to maintain a displacement amount equivalent to that obtained during application of a driving voltage, in a no voltage-loaded state after completion of application of the driving voltage.

摘要： A piezoelectric/electrostrictive actuator includes a plurality of piezoelectric/electrostrictive elements arranged in comb teeth-like alignment on a base plate. The actuator is driven by means of dislocation of the piezoelectric/electrostrictive elements. The cell driving type actuator is characterized in that each of the cells is formed independently from adjacent cells by positioning cover plates between two adjacent piezoelectric/electrostrictive elements. Thus, there is provided a piezoelectric/electrostrictive actuator wherein a heating process at a high temperature can be applied and mass production at low cost is possible. The actuator includes cells with slit portions having a width of 60 μm or less and a high aspect ratio and can be activated with high electric field strength, and great displacement can be obtained with small electric field strength.

摘要： A piezoelectric/electrostrictive film-type actuator has a ceramic base and a piezoelectric/electrostrictive element, which has piezoelectric/electrostrictive films and electrode films and which is disposed on the ceramic base, and is driven in accordance with a dislocation of the piezoelectric/electrostrictive element. The piezoelectric/electrostrictive element is formed such that the piezoelectric/electrostrictive films and the electrode films are alternately laminated so as to construct the uppermost layer and the lowermost layer with the electrode films. Also, the piezoelectric/electrostrictive films have two layers and no pores, containing a different phase formed by a decomposed material thereof, in the boundary sandwiched therebetween. In addition, the upper layer of the two-layered piezoelectric/electrostrictive films is thicker than the lower layer. This piezoelectric/electrostrictive film-type actuator solves the problem in that a withstand voltage of the piezoelectric/electrostrictive films is likely to decrease, and effectively achieves a bending dislocation.
