摘要： Protrusions made of an electrically conductive material such as a metal or ceramic are formed around a node point or a node line of vibrations of a piezoelectric plate on two principal planes thereof by a spraying process. The piezoelectric plate is held at the protrusions with leaf springs on the two principal planes. Thus, protrusions of a small surface area are formed without deteriorating the piezoelectric plate. The piezoelectric plate can be held stably without deteriorating the vibration characteristics. An alternating voltage is applied to electrodes of the piezoelectric plate through the electrically conductive protrusions. Because a spraying process is used, the protrusions can be thickly and precisely formed in a small area and held surely and reliably, with a good mechanical strength of the protrusions.

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.
