Abstract: front page image
(EN)A complicated operation or process is performed by generating acoustic waves or oscillation by a piezoelectric device. Equipment includes the piezoelectric device provided with a piezoelectric element composed of a piezoelectric material, and a plurality of electrodes, which are arranged on the both planes of the piezoelectric element and are formed by a metal thin film pattern. On the piezoelectric element, a groove is arranged at a position on the external side of the electrodes.
(FR)Une opération ou un processus compliqué est réalisé en générant des ondes acoustiques ou une oscillation par un dispositif piézoélectrique. L'équipement comprend le dispositif piézoélectrique fourni avec un élément piézoélectrique composé d'un matériau piézoélectrique et de plusieurs électrodes, agencées sur les deux plans de l'élément piézoélectrique et formées par un motif de fine pellicule métallique. Sur l'élément piézoélectrique, est agencée une rainure placée du côté extérieur des électrodes.
(JA) 圧電デバイスによって音波又は振動を発生させて、複雑な操作又は処理を提供することにある。本発明の機器は、圧電材料からなる圧電素子と該圧電素子の両面に設けられ金属薄膜パターンによって形成された複数の電極とを有する圧電デバイスを含む。上記圧電素子には上記電極の外側の位置に溝が設けられている。
