Abstract: 磁歪アクチュエータは、巨大磁歪物質のロッド（２）と、そのアクチュエータの両端部に配置され、かつロッドを通して磁場を通過するようにアクチュエータと同軸で配置されるバイアス印加する永久磁石（４）と、および交番磁場をロッドを通過する磁場上に重畳して、それに応答してロッドの長さに変化を生じさせるように、付勢手段へ接続される付勢電磁コイル（６）とから構成され、そこにおいて、永久磁石（４）は、それぞれがロッドのものよりもかなり大きい断面積を有する、円板の形態であり、およびロッド内の磁場がロッドの長さ方向に沿ってほぼ直線状であるように、低い磁気透磁率の物質（３）によりロッドの両端部から離間される。

Abstract: PROBLEM TO BE SOLVED: To provide a magnetostrictive material whose magnetostrictive properties are improved by chromium nitride, and to provide a magnetostriction type torque sensor.
SOLUTION: The magnetostrictive material is obtained by forming chromium nitride on the surface layer part of an iron based material containing, by weight, 8 to 30% chromium. The chromium nitride can be formed by subjecting the chromium-containing iron based material to nitriding treatment. The chromium nitride preferably consists of Cr(
1-X )N
X (x=0.3 to 0.7). By using the magnetostrictive material, the shaft of a magnetostriction type torque sensor can be formed.

Abstract: PROBLEM TO BE SOLVED: To provide a small-size magnetostriction actuator obtainable of a predetermined amount of deflection by applying a weak magnetic field, and its driving method as well as an optical switch utilizing the magnetostriction actuator. SOLUTION: In the magnetostriction actuator, a magnetic field is applied on a magnetostriction element piece arranged on a cantilever in a gap, for example, employing a magnetic field application device. In this case, the magnetic field is applied on the magnetostriction element piece in a direction orthogonal to the contracting direction of a magnetostriction film of the magnetostriction element piece. The magnetostriction film of the magnetostriction element piece is elongated or contracted by the application of a magnetic field whereby a shear stress is generated between the substrate of the magnetostriction element piece and the magnetostriction film. According to this phenomenon, the magnetostriction element piece is deflected into either upward or downward vertical direction with respect to the surface of the element piece. Further, the switching of light is effected by employing the magnetostriction actuator. COPYRIGHT: (C)2004,JPO
