摘要： PURPOSE:To make it possible to form composite piezo-electric materials of various properties simply by making the kind of resin to be filled different and forming filled organic substance in the double layer structure of two kinds of resins. CONSTITUTION:A vibrator 201 is temporarily bonded to a stand 203 with a bonding agent 202. Then, the vibrator 201 is cut in matrixlike form to about half of its thickness to form a cut groove 204. A resin 207 such as polyurethane, epoxy, etc. is filled in the cut groove 204 and cured and the bonding agent is melted. The vibrator is turned backward and bonded to the stand 203 with wax, etc. A cut groove 209 until arriving at the cut groove 204 is formed, and filled with the resin, etc. and cured 210 to form a resin part on the back side of the probe. A composite material is made by malting the wax and stripping off from 203. Above-mentioned resin 207 is made different in material quality from 201. For instance, one of epoxy, polyurethane, silicone rubber, etc. is used as the resin 207 and 210. Resins different in material quality can be used, and combinations of epoxy and polyurethane, epoxy and silicone rubber, polyurethane and silicone rubber etc. can also by used.

摘要： PURPOSE: To form an ultrasonic beam without suprious response in a planar piezo-electric body for ultrasonic probe, by arranging numerous grooves on the surface opposite to the surface having a plurality of electrodes.
CONSTITUTION: In a planar piezo-electric body 1 for ultrasonic probe for transmitting ultrasonic wave into and receiving it from a medium to be measured, grooves G
1 WG
5 are so arranged on the surface opposite to the surface having a number of split electrodes A
1 WA
5 that the grooves G
1 WG
5 and the boundaries dividing the electrodes A
1 WA
5 cross one another at the angle except for zero when projecting in the x-axis direction. With such an arrangement, waves of sound which are generated and propagated through the planar piezo-electric body 1 along the length thereof when the split electrodes A
1 WA
5 are driven scatter and damp noticeably in the reflection on the surface forming the grooves G
1 WG
5 . This eliminates suprious response which otherwise is caused by the radiation of partial waves of the propagation mode into the medium being measured thereby forming a better ultrasonic beam.

摘要翻译：目的：通过在与具有多个电极的表面相对的表面上布置多个凹槽，在超声波探头的平面压电体中形成无重大响应的超声波束。构成：在用于将超声波从待测介质传输并从其接收的超声波探头的平面型压电体1中，沟槽G1〜G5配置在与具有多个分割电极A1- 如图A5所示，当沿x轴方向投影时，沟槽G1-G5和划分电极A1-A5的边界以除零之外的角度彼此交叉。通过这样的布置，当分割电极A1-A5被驱动时，沿着其长度产生并传播通过平面压电体1的声波在形成沟槽G1-G5的表面上的反射中飞散和显着地变化。这消除了由测量的介质中传播模式的部分波辐射引起的重要响应，从而形成更好的超声波束。

摘要： PURPOSE:To improve the stability to an applied voltage by selecting a specific resistance of a zinc oxide thin film to >=10 OMEGA.cm when a DC voltage of 3V/mum is applied to increase the dielectric strength. CONSTITUTION:An end face of a quartz glass 1 is subjected to optical polish and a chromium and gold electrode 2 is vapor-deposited. A zinc oxide thin film 3 is formed on the electrode by high-frequency magnetron sputtering.

摘要： PURPOSE:To regulate a shape of a ultrasonic beam and to accomplish a beam scan by forming a chrominum film on a base board, then forming a lower electrode of a gold film pattern on said chrominum film and employing a characteristic of the gold electrode film. CONSTITUTION:A single surface of a base board 60 is optically ground, and a chrominum film 61 is deposited thereon. Then, on the chrominum film 61, pattern gold films 62-1-62-n are formed by photolighography. By using said films as a base board a zinc oxide thin film 63 of about 4mum is formed by high frequency magnetron/spattering, and upper electrodes 64-1-64-n are formed thereon by overlapping gold film pattern of the lower electrodes 62-1-62-n, which is made to a ultrasonic transducer with array structure. When n-number of elements consisting of the lower electrodes 62-1-62-n and the upper electrodes 64-1-64-n are sequentially switched and driven by plural elements so as to irradiate a sound wave, its beam can be scanned in a sharp beam shape in the direction of the array.

摘要： PURPOSE:To generate a short ultrasonic pulse by making the frequency characteristic of an ultrasonic probe broad-band, by constituting the ultrasonic probe by embedding a large number of columnar piezoelectric bodies in an org. material. CONSTITUTION:For example, a large number of columner bodies 22 comprising lead zircotitanate (PZT) ceramic are embedded in a polyurethane resin 21 and this resin 21 is formed into a planoconvex shape (a) or a planoconcave shape (b) to obtain an ultrasonic probe. In fabricating this probe, PZT ceramic 32 of a planoconvex plate is placed on a ferrite substrate 31 and notches are provided thereto. Next, the polyurethane resin 34 is injected in the notches and solidified. Subsequently, the molded one is detached and the concave surface part of the ceramic 32 is placed on a separate convex ferrite substrate 33 and notches are similarly formed to the back side thereof and the polyurethane resin 34 is injected in the notches. Because the obtained probe is formed as a composite piezoelectric body wherein a large number of columnar piezoelectric bodies are embedded in an org. substance, it has a broad-band characteristic and is easily fabricated.
