    摘要： A soft magnetic alloy powder containing Fe—Ni-based crystal particles is provided as one capable of adequately reducing core loss of a powder magnetic core and achieving satisfactory magnetic characteristics at an effective operating temperature of an element. The present invention provides a soft magnetic alloy powder containing Fe—Ni-based crystal particles containing 45 to 55 mass % Fe and 45 to 55 mass % Ni, relative to a total mass of Fe and Ni, and containing 1 to 12 mass % Co and 1.2 to 6.5 mass % Si, relative to a total mass of Fe, Ni, Co, and Si.

    摘要： A magnetostrictive actuator includes: a driving unit composed of generally plate-like positive and negative magnetostrictive elements laminated in a direction of thickness, being arranged generally in parallel with a drive surface of a driven member; a driving coil for applying a magnetic field to the driving unit longitudinally, being arranged around an outer periphery of the driving unit; and a pair of bias magnets for applying a bias field to the driving unit longitudinally, being capable of transmitting a displacement of the driving unit to the driven member. The magnetostrictive actuator is capable of miniaturization and space saving as compared to heretofore, and can produce a greater amount of displacement.
