    摘要: A process and a small, sensitive, low noise, high gain, power amplifier used in the process, for exploiting the anisotropic magnetoresistance effect in a ferromagnetic thin-film. The magnetization of the thin-film is biased to lie along the hard axis. The amplifier is configured so that a sensing current in the thin-film flows at an angle of forty-five degrees to the nominal direction of magnetization, and the current to be amplified produces a magnetic field parallel to the easy axis of the thin-film.

    摘要: A magnetoresistance detector linearly stretching single bits of binary inmation such as those represented by Bloch line - crosstie pairs, along the major dimension of a thin magnetic film strip such as a serriform crosstie memory. The detector circuit is overlaid upon the thin magnetic film strip. In a selected area, less pronounced serrations in the adjacent margins, in conjunction with a magnetic field created by current through the detector circuit enable Bloch lines entering the area to travel farther. A series of oriented open segments in the overlain section of the detector circuit, arranged in symmetric correspondence with serrations in the adjacent margins, enhances the difference between logical zero and one signals in the detector circuit.

    摘要: A router collet for removably attaching a rotary cutting tool to a router drive shaft is provided having a body, a split collet, a nut and a retainer for retaining the collet and nut together to permit free rotation while limiting axial movement therebetween. This construction enables the nut when loosened to initially rotate with the split collet and cutting tool for limited axial distance whereupon further axial movement of the collet is constrained causing the split collet and nut to separate and the split collet to loosen its grip upon the cutting tool shank.

    摘要: A magnetic crosstie memory using a plurality of Permalloy thin-film strips of uniform thicknesses having parallel denticulated margins etched to align with the oblong axis of the strip. Each pair of opposite denticles defines a distinct memory cell. Magnetization relaxes upon removal of a magnetic field applied normal to the oblong axis of the thin-film with each component assuming that orientation requiring the least rotation for parallel alignment with the least distant edge. Two domains are thus formed with a domain wall suitable for storage and propagation of binary information centered between the margins and extending the length of the strip. Crossties form at the necks of the serrations and Bloch lines are positioned in potential wells between the necks. Binary information, represented by the crosstie and Bloch lines in various conventions is propagated along the domain wall from cell to cell by particular sequences of magnetic pulses.
