Title
(EN) THIN-FILM ACTUATOR AND INKJET HEAD
(FR) ACTIONNEUR À FILM MINCE ET TÊTE À JET D'ENCRE
(JA) 薄膜アクチュエータ、及びインクジェットヘッド
Abstract
(EN)
Provided is a thin-film actuator, which comprises a thin-film layer having a displacement film that expands and contracts in the direction of the film surface in accordance with drive signals, and a substrate, to which both ends or the edges of the thin-film layer are anchored such that the thin-film layer is displaced in the direction orthogonal to the film surface with the expansion of the displacement film produced by the drive signals. The thin-film layer has initial stress in the direction of expansion along the film surface when not driven.
(FR)
L'invention concerne un actionneur à film mince comprenant une couche à film mince incluant un film de déplacement qui se dilate et se contracte dans la direction de la surface du film en fonction de signaux d'attaque, et un substrat sur lequel les deux extrémités ou les côtés de la couche à film mince sont fixés, si bien que la couche à film mince est déplacée dans la direction orthogonale à la surface du film en raison de l'expansion du film de déplacement produite par les signaux d'attaque. La couche à film mince possède une contrainte initiale dans la direction de l'expansion le long de la surface du film lorsqu'elle n'est pas excitée.
(JA)
 駆動信号により膜面に沿った方向に伸縮する変位膜を有する薄膜層と、薄膜層の両端または周縁を固定し、駆動信号による変位膜の伸長により、該薄膜層を膜面に垂直な方向に変位させる基板と、を備えた薄膜アクチュエータであって、薄膜層は、非駆動時、膜面に沿って伸長方向の初期応力を有している。
