    Abstract: PURPOSE:To convert strong vibration enegy of supersonic wave into rotation or linear movement by utilizing traveling wave combined with lateral wave and longitudinal wave excited on the surface of an elastic material. CONSTITUTION:A surface wave combined with a lateral vibration and a longitudinal vibration is formed on the surface 1a of an elastic material 1 such as metal. This surface wave is called ''Rayleigh wave'', and transmitted along the surface 1a of the elastic material 1. This Rayleigh wave is generated by exciting a vibrator which laterally or longitudinally vibrates. When the surface of a free movable body 2 is pressurized in contact on the surface 1a of the material 1 under this state, this body 2 is driven by the frictional force with the elastic body 1.

    Abstract: To provide a multi-purpose type magnetostrictive device that may be used as an acceleration sensor or a vibration sensor capable of detecting forces acting in more than one direction and which may also be employed as a torque sensor, an actuator, a motor and the like. Coils 110 to 310 of magnetostrictive bodies 10 to 30 are wound around magnetostrictive members 120 to 320 in such a manner that voltages corresponding to enlongation/contraction of the magnetostrictive members 120 to 320 are generated. The magnetostrictive members 120 to 320 are each constrained at the two ends. The magnetic circuits 130 to 330 apply a bias magnetic field to the magnetostrictive members 120 to 320. The magnetostrictive bodies 10 to 30 are positioned so that they are all aligned in the direction of the Z axis which is taken in the direction of the two ends of each of the magnetostrictive members 120 to 320 and they are also arranged in such a manner that a relationship is maintained in which, on the flat plane formed by the X axis and the Y axis running at a right angle to the direction of the Z axis, a polygonal flat plane S is constituted by connecting the points P1 to P3 at which the magnetostrictive bodies 10 to 30 are positioned, the number of sides of which corresponds to the number of bodies.

    Abstract: PURPOSE:To simplify the construction by elevationally polarizing an annular vibration element, providing electrodes equally divided into four or more on the upper and lower directions, and engaging a slider with the oblique surface of a drive ring. CONSTITUTION:An annular vibrator 1 is made of ceramic electrostrictive element, and polarized elevationally to form four or more (8 in the drawings) equally divided electrodes 3 on the lower surface. Inner and outer oblique surfaces 4, 5 having equal oblique angles are formed on an earth side electrode 3 of the upper surface, and bonded with a drive ring 6 of isosceles triangular shape of section. A disk-shaped slider 7 having an interlocking surface 8a planely contacted with the inner oblique surface 4 is placed on the ring 6. Thus, alternating voltage (Vsinomegat) displaced in timing phase of 2pi/x (x is the number of division) is applied to the electrode 3 to obtain the excitation of traveling wave to rotate the slider 7.
