するためのらのである。(i) As shown in FIG. 1(a), a relatively thick rectangular ceramic 4 that has been polarized in advance is
A vertical groove 4C1 and a horizontal groove 4d are formed along the a and 4b, and the vertical groove 4c and the horizontal groove i4d are filled with an adhesive 5 such as an epoxy resin and cured, as shown in FIG. 1(b). This adhesive 5 is used to bond the short columnar ceramic pieces 4e with a square cross section formed by the vertical grooves 4C and @iM 4 d.
ここで、セラミック片４ｅの一辺の寸法ａは、超音波の
波長に比へて十分小さい値に設定される。Here, the dimension a of one side of the ceramic piece 4e is set to a value sufficiently small compared to the wavelength of the ultrasonic wave.

充填というような手順を経るのが望ましい。Further, the vertical grooves 4c and the t&grooves 4d are recut by a guising tool. Therefore, if a short columnar ceramic piece 4e is suddenly formed, the reinforcing effect of the adhesive 5 will not be obtained at all, and the vertical groove 4c (or 11!1ii44d
), the horizontal groove 4d (
Or when cutting the vertical groove 4c), the ceramic piece 4e
chipping is more likely to occur. For this reason, it is best to go through the following steps: canting one groove (vertical or horizontal), filling that groove with adhesive, cutting the other groove, and filling that groove with adhesive. desirable.
