摘要： A novel non-mechanical optical fiber switch contains a magneto-optic element and a tubular magnet. The magneto-optic element is disposed within the field of the magnet but outside of the magnet bore. The beam of radiation from the switch input to the switch output passes through the axial bore of the magnet. The magnet contains magnetically anisotropic material, preferably a deformation-aged alloy having Fe, Cr and Co as major constituents. The switch is advantageously used in optical fiber communication systems.

摘要： A method of making a ribbon-like or sheet-like superconducting composite body is disclosed. The method is well suited for making long lengths (e.g.,>100m) of ribboon or large areas (e.g.,>100cm.sup.2) of sheet-like composite. The method comprises forming a Bi-Sr-Ca-Cu-oxide-containing layer on a metal (exemplarily Ag) substrate, and mechanically deforming (typically by rolling) the thus formed composite such that the oxide is densified to more than 80% of the theoretical density. Subsequently the oxide layer is at least partially melted and allowed to re-solidify such that a large portion of the oxide crystals has c-axis alignment. After appropriate heat treatment in an O.sub.2 -containing atmosphere, thus produced superconductor ribbons or sheets can have high J.sub.c).gtoreq.10.sup.4, frequently >10.sup.5 A/cm.sup.2) for temperatures less than about 20K and in magnetic fields less than about 5T.

摘要： Devices such as, e.g., switches, flowmeters, and proximity sensors, as well as implant devices are made comprising an elongated ferromagnetic element. When the element is exposed to a variable magnetic field an electrical signal is obtained between contact points of the element in response to a change in the magnetic field. Preferred elongated elements have a helically deformed microduplex structure as may be produced by heat treatment and plastic twisting of a body of an alloy such as, e.g., an iron-nickel alloy.

摘要： Electrical interconnection is established by means of an anisotropically conductive, composite layer medium comprising electrically conductive particles in a nonconductive matrix material. Enhanced uniformity of conductivity across the medium, and minimized incidence of lateral shorting are achieved as a result of essentially uniform distribution of electrically conductive particles which are also magnetic, such distribution resulting upon application of a magnetic field essentially perpendicular to a layer before or during hardening of the matrix material.

摘要： To provide for an inexpensive magnet alloy, isotropic and nearly isotropic permanent magnet properties are developed in Fe-Mo-Ni alloys. Manufacture may be by a method which comprises steps of annealing, optional deforming by a limited amount, and aging.Typical magnetic properties of alloys of the invention are a coercive force in the range of 50-500 oersted, a magnetic remanence in the range of 7000-14000 gauss, and a magnetic squareness ratio of less than 0.9. Alloys of the invention are highly ductile even after plastic deformation, they are readily bonded to aluminum supports (as used, e.g., in the manufacture of twistor memories), and they are readily etched by etchants which leave aluminum unaffected.

摘要： We have discovered that the addition of a relatively small amount of Sr and/or Ba to La-Ca-Mn-O can yield material of improved magnetoresistive properties at room temperature and in a small applied field, as compared to the analogous Sr and/or Ba-free material. An exemplary composition is La.sub.0.55 Ca.sub.0.25 Sr.sub.0.08 MnO.sub.x. Material according to the invention has a substantially larger value of .vertline.d.rho./dH.vertline. than the analogous comparison material at 25.degree. C. and H.ltoreq.0.05 Tesla. Preferred compositions also can exhibit a substantially linear dependence of resistivity on applied magnetic field under these conditions, as well as have a relatively large value of zero field resistivity. The novel materials can advantageously be used in applications that involve sensing of a magnetic field, or of changes in such a field.
