摘要： We have made the surprising discovery that small amounts of Ag below 1% by weight are effective in making Bi--Sn alloys less strain-rate sensitive without deleteriously affecting the melting character of the alloy. A Pb-free solder composition comprising at least 40% by weight Bi, between 40% and 60% Sn, and between 0.05 and 1% Ag is effective to increase the total elongation of the solder by at least 20% under the same processing conditions. Moreover the solder is free of undesirable Ag-containing phases with a melting point in excess of the 183.degree. C. melting point of the Pb--Sn binary eutectic alloy. In a preferred embodiment, the composition comprises 54.75% Bi, 45% Sn, and 0.25 % Ag.

摘要： In accordance with the present invention, a voltage proportional replication device comprises an input electromagnet responsive to an input voltage for producing a magnetic field in proportion to the input voltage; and a first magnetoresistive sensing element disposed within the field of the input electromagnet. The device further includes an adjustable source of output voltage; an output electromagnet responsive to the output voltage for producing a magnetic field in proportion to the output voltage; and a second magnetoresistive sensing element disposed within the field of the output electromagnet.

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.

摘要： New solder compositions which can have improved mechanical properties are disclosed. In a preferred embodiment, the solder comprises a matrix material and magnetically dispersed particles. A desirable dispersion of the magnetic particles in the matrix material, is accomplished by applying a magnetic field to the molten matrix material containing magnetic particles and solidifying it in the presence of the magnetic field. The particle-dispersed microstructures improve the mechanical properties of the solder composition. The improved solder composition can be made into a powder to be used in solder paste, cream or reshaped while substantially retaining the improved mechanical properties.

摘要： A method of producing normal-metal-clad superconductive oxide wire, tape and the like is disclosed. The method comprises forming an intermediate body by surrounding a quantity of the oxide powder (e.g., Ba.sub.2 YCu.sub.3 O.sub.6.9) with an appropriate normal metal jacket, reducing the cross section of the intermediate body by any appropriate technique (e.g., drawing or rolling), and heat treating the elongated body such that substantial sintering of the powder results, and such that, after completion of the heat treatment, the sintered oxide has a composition that is associated with superconductivity in unclad bulk samples of the oxide. The latter condition requires that at least the portion of the cladding that is in contact with the oxide powder is substantially inert with respect to oxygen and the oxide under the conditions of the heat treatment. Silver is the currently preferred inert normal metal. Exemplarily, Ag can be used to provide a diffusion barrier with other normal metal (e.g., Ni and Cu) surrounding the diffusion barrier, or the cladding can consist substantially of Ag. Various techniques for preventing oxygen loss and/or restoring lost oxygen from the powder are disclosed. Advantageously the elongated body is appropriately shaped (e.g., wound into a helical coil) prior to the heat treatment. Elongate bodies produced according to the invention can advantageously be used as superconductive magnets, and in a variety of other apparatus and systems.

摘要： Devices, systems and techniques are described for producing and implementing articles and materials having nano-scale and microscale structures that exhibit superhydrophobic, superoleophobic or omniphobic surface properties and other enhanced properties. In one aspect, a surface nanostructure can be formed by adding a silicon-containing buffer layer such as silicon, silicon oxide or silicon nitride layer, followed by metal film deposition and heating to convert the metal film into balled-up, discrete islands to form an etch mask. The buffer layer can be etched using the etch mask to create an array of pillar structures underneath the etch mask, in which the pillar structures have a shape that includes cylinders, negatively tapered rods, or cones and are vertically aligned. In another aspect, a method of fabricating microscale or nanoscale polymer or metal structures on a substrate is made by photolithography and/or nano imprinting lithography.
