摘要： PURPOSE:To realize an ultrasonic diagnostic apparatus of high practicality by a method wherein a probe is moved to determine a region to he diagnosed while the tomographic image due to a real time image reproducing system of an examinee is observed and the tomographic image of the region to be diagnosed is constituted by program operation. CONSTITUTION:The probe 1 which is given a pulse from a transmission driver 2 sends an ultrasonic wave into an examinee and receives the reflected wave from the interior of the examinee. The reflected wave converted to an electric signal is inputted to the first and second signal processing circuits 3, 5 and the signal processing circuit 3 reproduces an image within a real time to output a result to the first image display apparatus 4. In the reproduction of the image, at first, the signals received by the respective elements of the probe 1 are inputted to a plurality of analogue delay lines 7 to match the phases of the respective signals and, next, the signals matched in phase are mutually added by an adder 8 and the added signal is passed through a detection circuit 9 to form an image signal. The user of this apparatus sets the probe 1 to a region desired to be diagnosed while monitors the image due to real time processing and performs the reproduction of the image due to program operation by the signal processing circuit 5 to output a result to the second image display apparatus 6.

CONSTITUTION:An ultrasonic physiotherapeutic apparatus consists of an apparatus body 1 and a fixing means 2, and this apparatus body 1 has such a structure as made up of setting up a small battery 4 of 3V, an ultrasonic generator circuit 5 and an ultrasonic vibrator body 6 vertically in laminated form, and it is designed so as to output 4MHz in frequency and an ultrasonic wave of 30mW/cm in intensity. In this small battery, a chargeable small battery or the like is used in this case. As for a piezoelectric transducer 6a of the ultrasonic vibrator body 6, a polyvinylidene fluoride/ organic/inorganic piezoelectric transducer is used. As for the fixing means 2, it is not necessarily restricted in particular if it is able to surely fix the apparatus body 1 to a human body (an affected part or the like) M in a state of being closely stuck on it, and in this case, such a pressure-sensitive adhesive tape as using a modacrylic adhesive is used.

摘要： PURPOSE:To realize a minute lens aperture by making the diameter of an acoustic wave beam projected toward an acoustic wave lens, larger than the aperture diameter of the acoustic wave lens. CONSTITUTION:As an acoustic wave propagation medium, a piezoelectric element 45 is formed on the end face of a columnar crystal 50 used with a sapphire, a fused quartz, etc., and on the other end face, a concave lens 55 is made. In such a constitution, the aperture diameter of the element 45 is set to 2rho0, the aperture diameter of the lens is selected as 2rho0/N (N=3, 5, 7), and also, as for length of the crystal 50 of the lens, it is cut so that a distance from the surface of the element 45 to the back focus of the lens becomes rho0/lambdaN (lambda: working acoustic wavelength). In this way, the acoustic wave of a Gaussian distribution is made incident on a lens interface, and a good convergent beam is obtained. Also, a sound absorbing material 60 such as an epoxy resin, etc., is added to a crystal-medium interface except the lens aperture part, so that a subsidiary maximum beam is not incident in a medium (water) 70. In this way, a minute lens aperture can be realized.

摘要： PURPOSE:To make information on film thicknesses of a rough plated surface available, by employing focusing ultrasonic-wave or allowing a reflected ultrasonic-wave signal from the plated film to interfere between another reference signals for checking degree of interference. CONSTITUTION:With a series of ultrasonic-wave styluses performing a X-Y plane instrumental 2-dimensional scanning with a 2-dimensional instrumental scanning system 120, a video signal representing a magnitude of reflected ultrasonic wave from an object to be plated 95 located inside a plating chamber 96 is displayed on a cathode-ray tube 130 for depicting plated condition of the object 95. Next, the object 95 is scanned in the direction of Z-axis with the instrumental scanning system 120. And, with a plated film 98 depositing over the object 95, as the surface of the film 98 approaches a stylus 70, when the stylus 70 in the Z-direction is so displace that its focus coincides with its surface, the displaced distance on the Z-axis becomes to represent the thickness of the film 98. Thus, the plated film thickness can be measured regardless of existence of undulations on the surface to be plated.
