Title: Piezoelectric actuator
Inventor: SONODA KOJI
IPC: H02N2/00
Filed: 1990-06-12
Abstract: PURPOSE:To decrease the number of parts by applying voltage having different phase to two piezoelectric actuators respectively, utilizing expansion and contraction generated by the application of voltage, converting expansion and contraction into a rotary motion by a rotational conversion section through a pawl and transmitting the rotary motion over a shaft. CONSTITUTION:When voltage is applied in the direction that piezoelectric ceramics are shrunk, a rotational conversion section 5 starts its revolution by a pawl 3 fitted at a front end and a shaft 4 begins to be rotated. Since the pawl 3 is separated from the rotational conversion section 5, revolution is stopped temporarily. Piezoelectric ceramics 2 are stretched while applying voltage in the direction that piezoelectric ceramics 1 are extended. The pawl 3 and the rotational conversion section 5 are brought into contact by applying voltage in the direction that piezoelectric ceramics shrink. The shaft 4 is turned in a stepped manner by repeating a series of said operation. Accordingly, the effect of electromagnetic noises can be ignored, and miniaturization and improvement in precision are enabled.

Abstract: PURPOSE:To generate uniform plasma along the surface of dielectric material deposited to the anode surface by providing an auxiliary anode connecting an impedance element to the positive pole in such a magnetic field where it is prevented for electrons to move between the cathode and anode. CONSTITUTION:A plurality of protrusions 9 are provided in the form of belts to the anode 1 in such a device as comprising the anode 1, cathode which extracts ions from the anode sheathed plasma generated by the anode 1 and magnetic field generating appratus which prevents movement of electrons between the cathode and anode 1. A dielectric material 7 is filled between protrusions so that it is closely placed in contact with the anode 1 and moreover the lines of an auxiliary anode 11 are closely disposed in parallel at the center on the dielectric material 7. The anode 11 and 1 are connected to each other through an impedance Z12. When a high voltage pulse is applied to the anode 1, a charging current flows through the anode 11 and a potential of anode 11 is different from the potential of anode 1. Such difference of potential causes surface discharge 8 between the protrusion 9 and the anode 11 and such discharging 8 occurs uniformly for almost the entire surface of dielectric material. Thereby, the dielectric material can be used for a longer period of time.
