摘要： PROBLEM TO BE SOLVED: To provide an optical switch having low insertion loss by preventing a movable member from tilting, even if the interval between an optical fiber fixation member for output and a movable member is made narrower and the magnetic attracting force between both members is increased, so as to secure sufficient self-holding force. SOLUTION: This optical switch has at least a substrate, the fixation member for fixing an optical fiber provided to the substrate, an optical fiber for transmission which is fixed to the fixation member and can elastically deform, the movable member made of a soft magnetic material which is provided as a cantilever structure, including the optical fiber as a beam for the fixation member, and a magnetic actuator which swings the movable member. The optical switch switches optical transmission, by swinging the movable member. A preventive member, which forms a bridge between the fixation member and movable member on the reverse side, is provided on the fixation surface of the optical fiber.

摘要： PURPOSE: To offer a low-cost magnetic alloy composed of a single alloy based on Fe-Cr-Co, having a complex magnetic propety, excellent in workability and abound in mass-producibility.
CONSTITUTION: A magnetic alloy comprises, by weight ratio 17W35% Cr, 8W20% Co, 0.1W10% Mo, 0.1W10% of one or more of V, Nb and Ta, and the balance being Fe. The alloy may contain 0.1W10% of one or more of Mn, Y, Cu, Zn, Al, C, R.E. and platinum-group metals as additional components. The alloy can be provided with a complex magnetic property by subjecting it to special heat treatment and working. That is, the complex magnetic property is obtained by solution-treating the alloy in an α+γ dual phase zone and utilizig the spinodal decomposition of each phase, a γ→α' transition mechanism and an age-precipitation-hardening mechanism so that mainly α contributes to a large coercive force while γ contributes to a small coercive force.
