    摘要: A piezoelectric filter is one not changing in the holding position of resonator in spite of impulse, small in the number of parts, easy to assemble from one direction, small, thin, and stable in characteristic. For example, as shown in FIG. 7, on electrode patterns on a package 10 forming wiring electrode patterns 11, holding protrusions 13 for holding resonators, and partition boards 14 for positioning resonators, a rectangular plate type piezoelectric resonators 12 are adhered with conductive adhesive. The rectangular plate type piezoelectric resonators 12 and the package 10 are adhered and reinforced from above with a vibration absorbing member 15, and wiring is formed from above the resonators by a wire bonding 16, thereby wiring resonators in a ladder form. Or, as shown in FIG. 11, after forming electrode patterns 102 on a piezoelectric substrate 101, a rectangular plate resonator 104 is cut out from a piezoelectric substrate 101 by laser in a shape consecutive to the piezoelectric substrate 101 by the node of length expander mode, and the piezoelectric substrate 101 is enclosed by a spacer 106 and a sheet 107 from above and beneath.

    摘要: An ultrasonic motor has a vibrating body 3 and a moving body 11 supported by a supporting component 7. A rounded lower end of the supporting component is supported in a tapered dent of a supporting base 10, and therefore when a side pressure is applied, it inclines to the supporting base so as to keep the contact between the vibrating body and moving body stable. As a result, a stable motor rotation is always obtained regardless of side pressure. A lead wire 8 is held between a metal elastic element 1 and supporting component, and is pressed against the elastic element. Hence, the lead wire, through contact with the elastic element, is electrically coupled to the common electrode on the upper surface of a piezoelectric element without soldering and without use of conductive resin.

    摘要: In an ultrasonic motor wherein an elastic travelling wave is excited in a vibrating stator comprising a piezoelectric element and an elastic element thereby to drive and a rotor which is disposed to touch the vibrating stator with pressure by friction forces, an ultrasonic motor having high efficiency is obtained. In the present invention, the above-mentioned vibrating stator is substantially disk-type, electrodes being provided to the piezoelectric element are disposed in a form of two sets of concentric circles having different phases with respect to each other in a circumferential direction in which the vibration is travelling, and have a constitution which excites the vibrating stator by flexural vibration modes of second order or higher in a radial direction and of third order or higher in the circumferential direction, and also, are designed so that at least mechanical impedances seen from each electrode become equal. By superimposing standing waves of the flexural vibration which are excited by those two sets of electrodes, the flexural vibration is made to travel in the circumferential direction, thereby to obtain a driving force.
