Abstract: PURPOSE:To increase the quantity of displacement by impressing constant voltage which exceeds the greatest value of driving voltage to one side electrode of an electrostrictive actuator and impressing constant voltage which is lower than the least value of driving voltage to the other side electrode. CONSTITUTION:Output voltage of an amplifier 14 is impressed to electrodes 11b and 12b that are sandwiched between electrostrictive plates 11 and 12 out of respective electrodes of bimorph electrostrictive actuators consisting of two sheets of electrostrictive plates 11 and 12. Constant voltages (+E0, -E0) which are fed to the amplifier 14 are impressed to electrodes 11a and 12a at both surfaces of the above plates 11 and 12. Then constant voltage which exceeds the greatest value of driving voltage is impressed to the electrodes 11b and 12b that are formed at one side main surface of the electrostrictive actuators and constant voltage which is lower than the least value of driving voltage is impressed to the electrodes 11a and 12a that are formed at the other side main surface of the foregoing actuators. The bimorph electrostrictive actuators in which the electrostrictive plates 11 and 12 are laminated are driven by one driving amplifier 14 and further, the actuators have linear displacement for drive voltage without having hysteresis in displacement; besides, a displacement generating device having a large quantity of displacement to driving voltage is obtained.

Abstract: PURPOSE:To efficiently drive a piezoelectric fan using a piezoelectric bimorph element and apply a necessary wind speed with a low voltage, by making an AC signal to be applied to the piezoelectric bimorph element for driving same into a rectangular wave. CONSTITUTION:Piezoelectric elements 6 are laminated to form a bimorph structure. When negative potential is applied to electrodes 5a and 5c, and positive potential is applied to electrode 5b, polarizable piezoelectric materials 2a and 2b are curved. This property is utilized for a piezoelectric fan to obtain a wind by applying an AC voltage to the electrodes and vibrating the piezoelectric elements. An AC signal to be applied for driving the piezoelectric bimorph elements is made into a rectangular wave. Accordingly, a large wind speed can be obtained most efficiently with a given voltage, and a necessary wind speed can be applied with a low voltage.

Abstract: PURPOSE:To obtain a solid-state image pickup device without generating picture quality deterioration such as moires with small size and light weight by providing a filter made of an acoustooptic material and using a piezoelectric transducer to propagate an ultrasonic wave. CONSTITUTION:A filter made of an acoustooptic material 3 is fitted to the front face of the solid-state image pickup element 4, the piezoelectric transducer 1 propagates an ultrasonic wave to cause ultrasonic wave diffraction. Thus, light made incident on a part being substantially optically ineffective comes to a photoelectric conversion aperture of the solid-state image pickup element 4 together with the vertical light thereby spreading the area of the photoelectric conversion aperture effectively. Thus, the picture quality deterioration such as moires is not caused, the device small in size and light in weight are attained and the solid-state image pickup device with low cost is realized.

Abstract: PURPOSE:To avoid deterioration of characteristics caused by depolarization even if a high electric field is applied by a method wherein electrodes are provided on both sides of the polarizing direction of a piezoelectric slipping effect type actuator element and a DC source is connected so as to apply an electric field with the same direction as the polarization to the element. CONSTITUTION:Two terminals of a driving source 30 are connected to electrodes 22 and 23 formed on a piezoelectric slipping effect type actuator 11. An electric field formed between the electrodes 22 and 23 deforms the piezoelectric slipping effect type actuator 11 and creates a fine displacement. A subsidiary source 60 is a DC source for preventing depolarization and its two terminals are connected to electrodes 41 and 42 formed on the piezoelectric slipping effect type actuator 11 and an electric field formed between the electrodes 41 and 42 has the same direction as the polarization of the element. With this constitution, the depolarization of the element can be avoided.
