  • the vibratory energy is discharged radially from the peripheral face R of the flange.
  • the radius of said flange may be calculated from the following equation.
  • Input Power 20 watts The vibratory energy from the transducer, which is fixed to face L or L, is shifted through 90 at the junction of the rod and flange which is one-quarter wavelength long from the transducer, and is then radially diverged from face R.
  • the vibration of output face R has less amplitude than that of input face L under these no load conditions. This is a characteristic of this embodiment.
  • FIGS. 2 and 3 vibratory energy transmitted from a transducer 1 to a rod-shaped transmission element is radially diverged from a circular flange l1 placed at a distance of one-quarter wavelength from the transducer.
  • FIG. 5 shows an extension of the principle.
  • the device of FIG. 5 has three flanges 18, 19 and 20 on a transmission rod 17. The flanges are spaced one-half wavelength apart and the distance between each end-face of the rod 17 and the neighboring flange is one-quarter wavelength.
  • the power from the transducer 1 is diverged to the peripheries of the three flanges.
  • a flange can be used for convergence instead of divergence of the vibratory energy.
  • the flange of FIG. 12 is given a regular polygonal periphery and the transducer is fixed to one flat peripheral face of the flange, the correlation between the vibration amplitude of the driven face and that of the discharge face is similar to that shown in FIG. 13. If transducers are placed on several flat peripheral sides of the flange, the energy from the transducers converges to the ends-of the rod element. Under no load conditions in an ideal case without losses, energy which is about equal to the total energy from the transducers, is discharged at 90 to its original directions at the output face.
  • the device of FIGS. 6 and 7 has a flange of regular octagonal shape.
  • a transducer is fixed to every alternate side of the flange shown in FIG. 7.
  • the vibratory energy from the four transducers is converged into the flange and then is discharged from one end-face of transmission element 21 after a change of direction.

  • the end-face of said transmission rod 21 is fitted with a reflection plate 22 as is shown in FIG. 9.
  • a reflection plate 22 as is shown in FIG. 9.
  • the device of FIG. 8 is a modification of that of FIGS. 6 and 7.
  • a circular flange is positioned onehalf wavelength from the octagonal flange 24.
  • the vibratory energy converged into the regular octagonal flange 24 is turned through 90 along transmission rod 23, and is then, after being shifted through 90 by circular flange 25, diverged radially.
  • the dimensions of the flange 25 are chosen as hereinbefore described.
  • FIG. 14 there is shown a structure suitable for obtaining a high output power for use in heavy industry.
  • This transmission body is made up of a rod-shaped transmission element 33 having a resonant length at the operating frequency.
  • Two supports 32 and 40 are located one-quarter wavelength from each end-face of the rod 33, and two flanges, and 31, of regular l2- sides polygonal periphery are spaced one-half wavelength apart and one-half wavelength from the supporters 40 and 32, respectively.
  • Twelve transducers are fixed to each flange by holes such as the holes 34, 35, 36, 37, 38 and 39.
  • the dimensions and operating conditions are as follows:
  • each of supporters 32 and 40 is the form of a small circular flange.
  • the dimensions of these flanges are made as small as possible since they lie on the length of a transmission element. Typically they may be about 8 mm in both width and height. It will be observed that they are positioned at displacement nodes in order to minimize disturbance of the operation of the device and that they are deliberately made non-resonant.
  • the correlation between the vibration amplitude at input face R and that of output face L, under no load conditions, is as shown in FIG. 16, it is seen that the ratio of output vibration amplitude to input vibration amplitude is more than 3 to I. This ratio is of particular importance for the purpose of most efficient utilization of the vibration energy.
  • the device of FIG. 14 facilitates synthesis of vibration energy by means of resonance vibration based upon the relation between the transducers and the transmission element. Both in input and output, the following equation applies:
  • the output vibration amplitude grows together with output vibration energy, which inturn, grows together with input vibration energy.
  • the ratio of output vibration amplitude to input vibration amplitude is about 3 to 1. This has been verified by actual no load tests, the results of which are shown in FIG. 16.
  • an output power of about 4,800 watts can theoretically be obtained with an input power of about 200 watts per transducer. In actual practice, however, the full theoretical output of 4,800 watts will not be obtained due to losses, etc. If the number of the flanges is increased, an even greater output can be obtained.
  • FIG. 18 An actual no load test was carried out to show the relationship between input power and output vibration amplitude and the results are shown in FIG. 18.
  • the device of FIG. 14 shown generally by 30, 31, 33
  • the plug 41 is connected to face L via an intermediary element 43.
  • the output vibration amplitude was measured as the input power to the transducers on flanges 30 and 31 was set at 80, 160, 200 and 240 volts.
  • the amplitudes were measured with a pickup 44 and the results thereof indicated by mV.
  • FIG. 18 shows the output with input energy supplied to transducers on each flange 30 and 31. An actual no load efficiency of about 85 percent was obtained.
  • the devices of the present invention may, of course, utilize tubular transmission elements in place of the solid elements described above.
  • the electro-strictive material lead zirconate titanate
  • a transducer component in the foregoing description.
