    Abstract: The magneto-resistive element which is composed of two ferromagnets (A, B) having the magneto-resistance effect, is disclosed and all the merits of a planar hole device and a magneto resistive element. Two ferromagnets A and B are connected in series, and arranged at a right angle, and the output (4) is obtained between A and B. The current source of the magneto resistive element is installed in the opposite side of the output (5).

    Abstract: An alloy for a magnetoresistive element has an ordered phase with superstructure and consists of nickel and cobalt atoms, and the ratio of the nickel atoms to the cobalt atoms by the number of atoms is substantially within the range of 40:60 to 60:40. A method of manufacturing an alloy for a magnetoresistive element includes the steps of preparing a substrate for a magnetoresistive element, and forming so a nickel-cobalt alloy film on the substrate at the temperature of more than 250 DEG C. that the alloy has an ordered phase with superstructure and the ratio of the nickel atoms to the cobalt atoms by the number of atoms is within the range of 40:60 to 60:40.

    Abstract: Apparatus is provided for producing an output signal upon sensing the proximity of a member having relatively high magnetic permeability. 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, which energizing current flows in a direction from one to the other of the current supply terminals. A bias magnetic field is provided in a direction perpendicular to one of the main current conducting paths and which is sensed by the element. A portion of this bias field is received by a member having a relatively high magnetic permeability which is proximate the element, thereby altering the distribution of the received portion of the bias field to produce a composite field which can be considered a vector formed of the bias field and the field attributed to the permeable material. The composite field is a function of the spacing between the element and the member and the longitudinal positioning of the member with respect to the element. This composite magnetic field is sensed by the element, whereby 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 member with respect to the magnetoresistive element.

    Abstract: 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.
