摘要： A method for manufacturing a piezoelectric /electrostrictive element includes a step of subjecting the piezoelectric/electrostrictive film to a heat treatment and a polarization treatment after the film is allowed to stand until the value of an electric constant has converged after the heat treatment. The piezoelectric/electrostrictive element manufactured in this method has small stress remaining in the piezoelectric/electrostrictive film, and predetermined performance regarding, for example, a displacement amount, a displacement-generating force, and an electric power efficiency (consumed electric power) as a piezoelectric/electrostrictive element (piezoelectric/electrostrictive film) is never spoiled.

摘要： A liquid-drop spraying device is provided which can perform a stable liquid discharge without making air bubbles produced in the liquid of the pressurized room as well as the amount of liquid supply per unit time is increased. As applying voltage signal to the piezoelectric / electrostriction element of the drive electronics is shown along with the passage of time, the liquid can be flowed into the liquid pressurized room uniformly, and without entrainment of bubbles from the nozzle side by making the initial discharge time constant being larger than the second discharge time constant in the range of a fall time T3 or T4 in which different discharges are in turn performed with discharge time constant and by suctioning the liquid at a slow supply speed from the inlet hole after liquid discharge. On the other hand, as for the liquid having started to move, since the liquid can be rapidly suctioned with the second smaller discharge time constant, the liquid supply can be performed smoothly and a driving period time T5 can be shortened comparing with the case of suctioning the liquid to the last with the initial time constant, thereby enabling a stable and large amount of liquid discharge per unit time period.

摘要： A vibration gyro sensor is constructed as follows. Namely, a detecting piezoelectric/electrostrictive element 12, which detects displacement generated in a direction perpendicular to a direction of vibration of a vibrator 2 when the vibrator is rotated, is provided on a detecting section. The detecting section is constructed by an integrated fired product made of ceramics together with the vibrator 2 and a support base 4. The detecting section is constructed by a first plate-shaped section 6 which is more thin-walled than the vibrator 2 and which has its principal surface extending in the direction of vibration. The piezoelectric/electrostrictive element 12 is formed in an integrated manner on the first plate-shaped section 6 in accordance with a film formation method. Further, a thin-walled second plate-shaped section 8, which is provided for decreasing rigidity in the direction of vibration and facilitating the vibration for the vibrator 2, is formed in an integrated manner so that its principal surface extends in the direction perpendicular to the direction of vibration. Accordingly, it is possible to obtain the vibration gyro sensor made of ceramics having excellent sensitivity, in which the characteristics of the vibrator are scarcely affected by an ambient magnetic field, processing or machining can be easily performed, and the electric characteristics can be advantageously adjusted.
