    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.

    摘要: Light-emitting elements are divided into chromaticity groups on the basis of their chromaticity. In a planar light source, light-emitting elements selected from two of the chromaticity groups are alternately provided in a longitudinal direction and in a transverse direction, respectively. The two chromaticity groups are substantially equally away from a target chromaticity in directions reverse to each other. Further, pairs of two of the light-emitting elements belonging to the two chromaticity groups which are separated from each other, are provided so that distances d2 at which two of the light-emitting elements in each of the pairs are provided are less than distances d1 at which the pairs are provided.
