摘要： A ferromagnetic thin-film based digital memory having a plurality of bit structures electrically interconnected with information storage and retrieval circuitry that avoids information loss in one bit structure because of operating the others through this circuitry. Each of these bit structures formed of a relative orientation maintenance intermediate layer having two major surfaces on opposite sides thereof with a pair of memory films of an anisotropic ferromagnetic material each on a corresponding one of said relative orientation maintenance intermediate layer major surfaces. The relative orientation maintenance intermediate layer is of a material and a selected thickness so as to maintain magnetizations of said memory films oriented in substantially opposite directions. Interconnection electrodes pairs are each in electrically conductive contact with a corresponding one of the bit structures on substantially opposite sides thereof near or at substantially opposite edges of the relative orientation maintenance intermediate layer major surface. A magnetization reference direction layer able to maintain relatively well its magnetization orientation can be provided across a nonmagnetic layer from one of the pair of memory films with the nonmagnetic layer being either electrically conductive or insulative.

摘要： A ferromagnetic thin-film based sensing arrangement having a plurality of magnetic field sensors on a substrate each having an intermediate layer of a nonmagnetic material with two major surfaces on opposite sides thereof with one of a pair of magnetically permeable films each of a magnetoresistive, anisotropic ferromagnetic material correspondingly positioned thereon with first and second oriented sensors therein respectively having a selected and a reversing magnetization orientation structure provided with one of said pair of permeable films thereof for orienting its magnetization in a selected direction absent an externally applied magnetic field in at least partly opposing directions. Alternatively, these magnetizations of the films can be oriented in the same direction but with the other film member of the pair provided adjacent a coupling layer that antiferromagnetically couples thereto a further ferromagnetic layer on an opposite side thereof of a lesser thickness for one sensor and a greater thickness for the other. Such a sensing arrangement can be formed by providing a succession of material layers on a substrate with one or more coupling layers for antiferromagnetically coupling ferromagnetic layers on opposite sides thereof including a permeable film. Selective removal of the succession follows to provide unequal numbers of coupling layers for the two kinds of sensors or unequal thicknesses of corresponding ferromagnetic layers corresponding to the coupling layer and the providing of a pinning layer for both kinds of sensors which are thereafter separated by further material removal.

摘要： A method and apparatus for humidifying residential and commercial buildings in which a flue gas generated by a residential or commercial furnace is provided to one side of a porous liquid water transport membrane and habitable space air is provided to an opposite side of the porous liquid water transport membrane in an amount sufficient to provide a habitable space air to flue gas volume flow rate ratio of at least 8.3:1. At least a portion of the water vapor in the flue gas is condensed, providing condensed liquid water which is passed through the porous liquid water transport membrane to the habitable space air side of the porous liquid water transport membrane. On the habitable space air side of the membrane, the condensed liquid water is evaporated into the habitable space air, producing humidified habitable space air which is provided to the rooms of the residential and commercial buildings. Beneficially, no supplemental water source is required for the humidification process.
