摘要： A monoblock dielectric duplexer comprises resonant holes. Conductive electrodes and couplers are formed on one side of the dielectric block, whose other sides are covered with a conductive material. The conductive electrodes in a transmit-filtering portion are formed in an inter-digitating manner while the conductive electrodes in receive-filtering portion are formed to be of pad-shape. In the duplexer, capacitances of capacitors comprised of the conductive electrodes are easily and accurately set to desired values by determining the number and/or the lengths of fingers that the inter-digitating electrodes have.

摘要： The present invention relates to a linear motor which draws its operating power from ultrasonic vibration above the frequency of 20 kHz which is generated by piezoelectric ceramic. More particularly, the invention relates to a linear piezoelectric ultrasonic motor which linearly operates a slider due to a frictional force generated by applying sinusoidal electric field with a 90 degree phase difference to a pair of piezoelectric ceramic. This causes an elliptical mechanical vibration on a shaking beam which is connected to the piezoelectric ceramic.

摘要： A ring type piezoelectric ultrasonic resonator includes a piezoelectric ceramic segmented for each quarter of wavelength of an applied AC electric field, wherein the piezoelectric ceramic is alternately polarized in polarization units each having two segments, and a sine wave AC electric field and a sine wave AC electric field having a predetermined phase difference from the sine wave AC electric field are alternately applied to each of the segments. Further, the number of the segments of the piezoelectric ceramic is an integral multiple of 4. Moreover, the sine wave AC electric field applied to each of the segments of the piezoelectric ceramic has a phase difference of 90-degree with respect to adjacent segments.

摘要： A piezoelectric linear motor for amplifying the change in at least one dimension of a piezoelectric material is disclosed. A shaft is connected axial-movably to a piezoelectric actuator. The actuator includes a piezoelectric ceramic that expands or contracts in response to an applied voltage. The expansion or contraction of the piezoelectric ceramic is amplified by converting the displacement due to expansion/contraction into a greater displacement of a top plate to which the shaft is coupled. The greater displacement is, for instance, by causing the expansion/contraction of the piezoelectric ceramic into a convex or concave bending of a complex of which the piezoelectric ceramic is a part. In a preferred embodiment the base plate is attached to the piezoelectric ceramic, a slanted plate conically extending from the base plate, and a top plate formed at the center of the slanted plate to form an assembly that changes its curvature to amplify the displacement.
