摘要： 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.

摘要： PURPOSE:To contrive to produce simply the tool horn with high freedom by providing one slit or more extending longitudinally at each 1/4 wave length in the direction of transverse width for the plate shape member having the transverse width equal to or more than 1/4 wave length, the longitudinal width equal to 1/2 wave length and the thickness equal to or less than 1/8 wave length. CONSTITUTION:A plate shape member has the transverse width equal to or more than 1/4 wave length of an used ultrasonic wave vibration, the longitudinal width equal to 1/2 wave length, the thickness equal to or less than 1/8 wave length and at least one slit or more extending longitudinally at each 1/2 wave length in the direction of the transverse width. Each part of the slit width equal to or less than 1/24 wave length, the column part width being in the range of 1/4-5/24 wave length and the bridge part width being in the range of 2/24-4/24 wave length is caused to be the same in dimension, and said plate shape member is caused to be symmetrical to vertical and horizontal (left and right) direction. The mixing of transverse wave into the longitudinal vibration on the emitting surface 2 is prevented by causing the slit width S to be equal to 1/24 wave length or less, and the longitudinal vibration on the emitting surface is uniformalized. For instance, when two slits, the slit width of 1/24 wave length, the columnpart width W of 1/4 wave length are used, the bridge part width T obtains the resonance frequency corresponding to the dimension in the range of 2/24-4/24 wave length.

摘要： PURPOSE:To measure easily acoustic output power at a practical particle speed level in a short time by moving an annular electromagnetic type oscillation detector along a transmitter and obtaining a maximum and a minimum output values. CONSTITUTION:The transmitter 10 in which the annular electromagnetic oscillation detector 12 is fitted movably is inserted into an ultrasonic oscillation system for outputting oscillation power generated by an oscillator 8 to an acoustic load 1. While the annular electromagnetic oscillation detector 12 is moved along the axis of the transmitter 10, the maximum value Vmax and minimum value Vmin of the ultrasonic particle speed in the transmitter 10 are measured to calculate an acoustic output Pa sent to the acoustic load from an equation. Further, a standing wave ratio SWR is calculated from Vmax/Vmin and the acoustic output Pa is calculated from an equation II. In the equations, K is a constant of proportion, rho the density of the transmitter, C the acoustic velocity in the transmitter, and S the sectional area of the transmitter.

摘要： PURPOSE:To simplify the structure by radially polarizing a circular vibrator, and equally dividing one of electrodes on the inner and outer peripheral surface into four or more, thereby forming a vibration wave motor of sole electrostric tive element. CONSTITUTION:A circular vibrator 1 made of a ceramic electrostrictive element is radially polarized inside into positive and outside into negative, equally divided at the inside into four to provide polarized electrodes 3. The outside becomes an earth side electrode 3. Further, a semicircular pressure contacting inner ring 5 is disposed through a contactor 4 on the inner peripheral surface, and similar semicircular pressure contacting outer ring 6 is provided on the outer peripheral surface. The rings 5, 6 are pressed to pressure contacting the vibrator 1 by pushing and pulling springs 9, 11. Thus, when an alternating voltage of phase displacement of 2pi/x is applied to the electrode 3 of the inner peripheral surface to obtain the excitation of a traveling wave, and a driven unit contacted with the electrodes 2, 3 can be rotated in the width having no node over the entire periphery.

摘要： PURPOSE:To measure acoustic output power easily at a practical particle speed level in a short time by inserting a transmitter in which an annular electromagnetic oscillation detector is fitted into an ultrasonic oscillation system, and detecting data at a node position of the standing wave in the transmitter. CONSTITUTION:The transmitter 10 in which the annular electromagnetic oscillation detector 12 is fitted is interposed between an acoustic load 11 and an oscillator 8, and the detector 12 is fixed at a node position of the standing wave in the transmitter to measure acoustic output power through the operation of an acoustic output meter part 9 or 9'. Namely, the transmitter 10 is run through the hole 4 of the detector 12 of this structure or circuit to transmit oscillation, and then voltages proportional to the particle speed are induced across coils 3 and 3'. Therefore, the sum of the two voltages is also proportional to the particle speed, so when the position where the sum voltage is reduced to minimum is derived, the position is as the node of the standing wave. The differential electric power between the coils 3 and 3' at the node position is proportional to force F, so the acoustic output power is found by calculating the product of the difference voltage and sum voltage.
