要約
(EN)
An adhesion layer (4) is formed between a piezoelectric element (3) and a base material (2) by using an adhesive with Shore D hardness of at least 80 HS to bond the both. The adhesion layer (4) is formed to a uniform thickness by disposing two spacers on a transfer sheet and spreading an adhesive between these spacers. Then, the base material (2) and the piezoelectric element (3) bonded by the adhesion layer (4) are heated under pressure to cure the adhesion layer (4). A high-hardness cured adhesion layer (4) can reduce vibration loss in the adhesion layer (4). A uniform-thickness adhesion layer (4) can reduce variations in vibration characteristics of a piezoelectric actuator (1).

Selon le mode de réalisation décrit dans cette invention, une couche d'adhérence (4) est formée entre un élément piézoélectrique (3) et un matériau de base (2) au moyen d'un adhésif présentant une dureté Shore D d'au moins 80 HS pour relier les deux. La couche d'adhérence (4) est formée sur une épaisseur uniforme par dépôt de deux éléments écarteurs sur une feuille de transfert, puis étalement d'un adhésif entre ces éléments écarteurs. Ensuite, le matériau de base (2) et l'élément piézoélectrique (3) reliés par la couche d'adhérence (4) sont chauffés à une pression afin de durcir la couche (4). Une couche d'adhérence (4) durcie présentant une dureté élevée peut permettre de réduire la perte de vibrations dans la couche d'adhérence (4). Une couche d'adhérence (4) présentant une épaisseur uniforme peut permettre de réduire les fluctuations de caractéristiques de vibration de actionneur piézoélectrique (1).

 ショアD硬度80HS以上の接着剤を用いて圧電素子(3)および基材(2)の間に接着層(4)を形成して両者を接着する。接着層(4)は、転写シートに二つのスペーサを配置し、これらのスペーサの間に接着剤を延ばすことで均一の厚みに成形する。そして、接着層(4)で接着された基材(2)および圧電素子(3)を加圧状態下で加熱して接着層(4)を硬化させる。硬化後の接着層(4)が高硬度なので、接着層(4)における振動損失を低減できる。また、接着層(4)の厚みが均一なので、圧電アクチュエータ(1)の振動特性のばらつきを低減できる。
