    摘要： A method of manufacturing an amorphous magnetic alloy having high permeability comprises the steps of:preparing an amorphous magnetic alloy ribbon having major surfaces;annealing said magnetic alloy ribbon at a temperature lower than the crystallization temperature of said alloy under the application of a first magnetic field in a first direction along said major surface for a period sufficient to induce a magnetic anisotropy in said first direction; andannealing said magnetic alloy ribbon at a temperature lower than the crystallization temperature of said alloy under the application of a second magnetic field in a second direction perpendicular to said first direction along said major surface until the induced magnetic anisotropies in said first and second directions become equal to each other.

    摘要： A method of manufacturing a high permeability amorphous magnetic alloy is disclosed. In the method amorphous magnetic alloy ribbon prepared by quenching a melt of raw material is annealed at an elevated temperature lower than a crystallization temperature of the alloy, in a magnetic field. During the annealing, the alloy ribbon and the direction of the magnetic field are relatively rotated with each other. The method is especially useful to an amorphous magnetic alloy having high saturation magnetic induction where the magnetic Curie temperature of the alloy usually exceeds the crystallization temperature of the alloy.

    摘要： Apparatus is provided for producing an output signal upon sensing the proximity of a source of magnetic field. The apparatus includes a magnetoresistive element which is comprised of an insulating substrate upon which first and second ferromagnetic strips are provided. The ferromagnetic strips define first and second main current conducting paths which are respectively perpendicular to each other. The strips are connected in series to define a junction therebetween from which an output signal is derived. Current supply terminals are provided for furnishing an energizing current to the magnetoresistive element. Impedances are connected in parallel with the series-connected strips to thereby form a bridge circuit with the ferromagnetic strips, the junction between the strips serving as a bridge output terminal. A generator magnet has a surface disposed in a plane spaced from the magnetoresistive element and produces a magnetic field which is sensed by the element. An output signal is produced from the junction in the element as a function of the relative positions of leading and trailing edges of the generator magnet with respect to a leading edge of the magnetoresistive element.
