摘要： An actuator 1 in which a displacement element 7 has a piezoelectric ceramic layer 4 and a pair of electrodes 5, 6 interposing therebetween the piezoelectric ceramic layer 4. The entire thickness of the actuator 1 is 100 μm or less. The piezoelectric ceramic layer 4 and the substrate 2 have as their principal component a perovskite crystal containing at least Pb; Zr and Ti, and, the maximum difference in a composition ratio Pb/(Ti+Zr) between the surface of the piezoelectric ceramic layer 4 and the inside of the substrate 2 is 0.02 or less.

摘要： An inkjet printer whose ink discharge characteristic will rarely change even when used for a long period of time is developed. The inkjet printer has a pressure chamber and a piezoelectric actuator and a controller. The piezoelectric actuator has a first electrode, a first piezoelectric film, a second electrode, a second piezoelectric film, and a third electrode, and they are laminated together in this order. The piezoelectric actuator forms a portion of the wall defining the pressure chanter. The controller applies ink discharge signal between the first and second electrode, ink discharge signal comprises advanced voltage change from a predetermined voltage to the lower voltage and subsequent voltage change from the lower voltage to the predetermined voltage. Ink can be effectively discharged by applying the ink discharge signal, but the ink discharge signal could change piezoelectric characteristic in the second piezoelectric film due to the deformation of the first piezoelectric film. The additional signal applying the second piezoelectric film via the second and the third electrode can reduce the changes of the piezoelectric characteristic. As a result, changes of ink discharge characteristic can be prevented.

摘要： The lnkjet printer has a pressure chamber, a plezoelectric actuator, and a controller. The plezoelectrlc actuator has a piezoelectric film, a first electrode, a second electrode, and a third electrode. The first electrode, positioned in the region facing the pressure chamber, and the third electrode, positioned adjacent to the first electrode, are attached on one surface of the piezoeiectric film. The second electrode is attached on an opposite surface of the piezoelectric film and overlaps the first and third electrodes. To discharge ink, the controller applies an ink discharge signal between the first and second electrodes comprising an advanced voltage change from a predetermined voltage to the lower voltage and a subsequent voltage change from the lower voltage to the predetermined voltage. The controller also applies a peripheral signal between the second and thIrd electrodes to prevent changes in characteristics of the piezoelectrlc actuator that may affect ink discharge.

摘要： A safety device having a thin plate of a brittle material adapted to be ruptured by a difference between pressures exerted on opposite sides thereof; and a conductive path provided on the thin plate and adapted to be cut off by the rupture of the thin plate. One surface of the thin plate is present in a reference pressure chamber. The safety device with its reference pressure chamber being sealed is incorporated in a secondary battery. When the secondary battery is overcharged, the pressure difference between the opposite sides of the thin plate is increased, so that the thin plate is ruptured to cut off the conductive path.

The inkjet printer has a pressure chamber and a piezoelectric actuator and a controller. The piezoelectric actuator has a piezoelectric film, a first electrode, a second electrode and a third electrode. The piezoelectric actuator forms a portion of the wall defining the pressure chanter. The first electrode is attached on the surface of the piezoelectric film and is positioned in the region facing the pressure chamber. The third electrode is attached on the surface of the piezoelectric film and is positioned adjacent to the first electrode. The third electrode is attached on the other surface of the piezoelectric film and is overlapping with the first and third electrode. The controller applies ink discharge signal between the first and second electrode, ink discharge signal comprises advanced voltage change from a predetermined voltage to the lower voltage and subsequent voltage change from the lower voltage to the predetermined voltage. Ink can be discharged by applying the ink discharge signal, but the ink discharge signal may change piezoelectric characteristic because, within the piezoelectric film, a deformed portion which is sandwiched by the first and second electrode and a non-deformed portion which is not sandwiched by the first and second electrode appear. The controller also applies peripheral signal between the second and third electrode. The characteristic change of the piezoelectric actuator that may be caused by application of the ink discharge signal can be prevented by applying the peripheral signal to the non deformed portion. The change of ink discharge characteristic that is caused by the characteristic chance of the piezoelectric actuator can be prevented.
