Title (EN) LAMINATED PIEZOELECTRIC ELEMENT AND ULTRASONIC MOTOR
(FR) ÉLÉMENT PIÉZOÉLECTRIQUE STRATIFIÉ ET MOTEUR ULTRASONIQUE
(JA) 積層圧電素子及び超音波モータ
Abstract: front page image
(EN)First internal electrode groups (23a, 25a, 27a) are provided with first exposed section groups (29a, 33a, 31a) formed at an end section of a first piezoelectric material (21a). Second internal electrode groups (23b, 25b, 27b) are provided with second exposed section groups (29b, 33b, 31b) formed at an end section of a second piezoelectric material (21b).
(FR)L'invention concerne un élément piézoélectrique dans lequel des premiers groupes (23a, 25a, 27a) d'électrodes internes sont pourvus de premiers groupes (29a, 33a, 31a) de sections exposées formés au niveau d'une section d'extrémité d'un premier matériau piézoélectrique (21a). Des deuxièmes groupes (23b, 25b, 27b) d'électrodes internes sont pourvus de deuxièmes groupes (29b, 33b, 31b) de sections exposées formés au niveau d'une section d'extrémité d'un deuxième matériau piézoélectrique (21b).
(JA) 第1の内部電極群(23a,25a,27a)は、第1の圧電材料(21a)の端部において形成された第1の露出部群(29a,33a,31a)を備え、且つ、第2の内部電極群(23b,25b,27b)は、第2の圧電材料(21b)の端部において形成された第2の露出部群(29b,33b,31b)を備える積層圧電素子。
