となっていた。However, in the conventional tire type probe described above, an unnecessary reflected wave is generated between the delay member on the front surface of the vibrator and the rotating tire type delay member, and An unnecessary reflected wave is also generated from the back surface of the tire-type delay material, so that the ultrasonic signal is attenuated. Also,
Since the unnecessary reflected wave generated from the back surface of the rotating tire-type retarder interferes with the reflected wave from the surface of the DUT, the reflected wave from the surface of the DUT is deformed and accurate measurement cannot be performed. The area immediately below this surface was an unmeasurable area.

被測定物に入射する。The ultrasonic wave emitted from the vibrator propagates through the delay material and reaches the boundary with the rotating tire-type delay material. Since it is filled with a liquid having substantially the same acoustic impedance as that of the above-mentioned material, the reflected wave from the back surface of the delay material is transmitted to the tire-type delay material with almost no generation. Further, the ultrasonic waves that have propagated through the tire type delay material and have reached between the surface of the object to be measured and the surface of the tire type delay material are supplied with a contact medium having substantially the same acoustic impedance as that of the material, The reflected wave from the bottom surface of the mold delay material is incident on the object to be measured with almost no generation.

The tire-type delay member 14 formed in a ring shape is rotatably fitted between the support plates 5 and 6, and the inner peripheral surface of the tire-type delay member 14 is supported by the ball bearing 13. In addition, this tire type retarder 1
In order to enable the rotation of No. 4, the gap (S) between this and the delay member 10 is set to maintain a gap of about 0.1 to 0.3 mm.

This is a configuration in which liquids such as glycerin and oil are fed. That is, the liquid feeding tube 15 is electrically connected to the other support shaft 3 and the support plate 5, and the tip thereof is opened toward the portion of the gap (S) between the delay member 10 and the tire type delay member 14. The other end is connected to a connecting tube 16 provided on the outer surface of the case 1.
Therefore, when a liquid feeding tube is connected to the connecting cylinder 16 and a lubricating liquid is fed, the liquid is filled in the gap (S).

中央部分に供給される。As another characteristic structure, the contact medium (n) having substantially the same acoustic impedance as that of the above-mentioned delay materials is also supplied to the surface of the tire delay material 14. . Specifically, a cap-shaped supply unit 17 is fixed to the center of the upper surface of the case 1.
7 has a through hole 18 formed therein and one end of which is the case 1
Is connected to a supply port 19 provided at the other end, and the other end is connected to a connection part 20 attached to the outer surface of the supply part 17. Therefore, when the tube 21 is connected to the connecting portion 20 to communicate with the storage tank 22 for the couplant, and the couplant is pushed out by the air pressure of the cylinder 23, the couplant (n) causes the tube 21 and the through hole 18 to pass. After that, it is discharged from the supply port 19 of the case 1 and supplied to almost the central portion of the surface of the rotating tire-type delay member 14.

At this time, a liquid (m) for lubrication such as glycerin or oil that makes the acoustic impedances of the two delay members 10 and 14 substantially equal to each other is fed from the tube 15 to both delay members
The gap (S) between 0 and 14 is filled. Further, a contact medium (n) having substantially the same acoustic impedance as the material of both the delay members 10 and 14 is sent from the tube 21,
It is supplied to the surface of the tire type retarder 14 through the supply port 19 of the case.

Is filled with the liquid (m) having substantially the same acoustic impedance as the material of both delay materials as described above, the reflected wave from the back surface 10a of the delay material 10 is hardly generated, and the tire-type delay material is Penetrate to 14.

Since the contact medium (n) having substantially the same acoustic impedance as that of the material is supplied to the surface of the tire type delay material 14, almost no reflected wave is generated from the bottom surface 14a of the tire type delay material 14, and the object to be measured (P ).

され、且つ信号波形が減衰することもないのである。The ultrasonic wave incident on the object to be measured (P) has a difference in acoustic impedance between the contact medium (n) and the object to be measured (P). Therefore, as shown in FIG. Although reflected from the front surface (P 1 ) and its back surface (P 2 ), unnecessary reflected waves do not occur at the time of incidence as described above, and therefore the reflected waves are not deformed by interference. In addition, the non-measurement area immediately below the surface of the object to be measured is greatly reduced, and the signal waveform is not attenuated.

Therefore, the passing area of the ultrasonic wave is reduced, but this is compensated for by using the focusing type vibrator that narrows the beam width of the ultrasonic wave as the vibrator 7, as described above.

Since a contact medium that makes the acoustic impedance of the tire-type delay material substantially the same as the acoustic impedance of the delay material is automatically supplied to the surface of the tire-type delay material, the front and back surfaces of the object to be measured are filled. The reflected wave from is not deformed, the signal waveform is prevented from being attenuated, and the signal can be received accurately, and it becomes possible to reduce the non-measurement area in the portion directly below the surface of the DUT. There is an effect that the accuracy of measurement by sound waves can be extremely increased.
