  • Patent number: 4800388
    Abstract: An apparatus for measuring pulse compression ratio which receives a pulse compression radar signal that has been phase-modulated by a two-phase code. The apparatus comprises a means for detecting a function of the number of times of phase inversion existing in the received pulse compression radar signal to obtain the pulse compression ratio corresponding to the function of the number of times of phase inversion.

  • Patent number: 4634916
    Abstract: A rotary driver is disclosed, which comprises a solenoidal oscillation element consisting of an electrostriction element polarized in radial directions or vertical directions and provided with electrodes on pair opposite surfaces perpendicular to the direction of polarization. The electrode on either one of the pair opposite surfaces is uniformly divided by x greater than four. AC voltages of V.sub.o sin .omega.t shifted in phase from each other by 2.pi./x are applied to the division electrodes. A driven member is held in contact with at least one of the opposite surfaces of the solenoidal oscillation element.

  • Patent number: 4556814
    Abstract: An improved ultrasonic transducer including an oscillation housing composed of a cylindrical side plate and a wave transmitting and receiving top plate provided at one end of the side plate, a piezoelectric element integrally bonded to the inside of the top plate for oscillation therewith, and electrodes arranged on the piezoelectric element so that ultrasonic waves may be generated from the top plate when an electric field is applied to the electrodes and/or an electric output is delivered from the electrodes when the top plate receives ultrasonic waves. The improvement includes the oscillation housing which is formed, at least in its top plate, of a porous plastic material.
