つの素子で磁気電気変換素子を構成できる。 Piezoelectric vibrators can be used to generate voltage by applying mechanical stress and strain, that is, to convert mechanical energy into electrical energy. On the other hand, magnetostrictive elements can be used to generate strain by applying a magnetic field. Therefore, by combining the two, a magnetoelectric transducer can be constructed with one element.

くもので、磁歪材料粉末と室温硬化型樹脂を混合
し、圧電体中の貫通孔に流し込むという簡単な方
法で、磁気電気変換素子を構成するものである。 Conventionally, a transformer has been considered in which a piezoelectric cylinder is inserted into a magnetostrictive cylinder having a through hole.
In this case, the piezoelectric material must be processed into a cylindrical shape, inserted into a through hole in the magnetostrictive material, and cemented together. In other words, the process is quite complicated and expensive in terms of processing and fixing. The present invention eliminates this drawback and constructs a magnetoelectric transducer by a simple method of mixing magnetostrictive material powder and room temperature curing resin and pouring the mixture into a through hole in a piezoelectric body.

The mixture was degassed using a vacuum clay kneading machine and then pressed and molded to obtain a molded body with a honeycomb structure as shown in the figure. After forming, gradually dry at room temperature, then
The mixture was further held at 700°C for 1 hour to incinerate organic substances. Then, it was sintered at 1250°C for 45 minutes. Silver paste was applied to both end faces perpendicular to the through-hole of the sintered porcelain and baked at 800°C. This was immersed in silicone oil at 100°C and polarized by applying a direct current electric field of 2 kV/mm for 1 hour.
