Abstract: In accordance with the invention, an electronic device having one or more contact pads is adhered to an array of transferable solder particles on a removable carrier sheet. The carrier is removed, as by dissolving, leaving solder selectively adhered to the contact pads. In a preferred embodiment the solder-carrying medium is water soluble, and the solder particles comprise solder-coated magnetic particles. Application of a magnetic material while the medium is drying or curing, produces a regular array of solder-coated particles. Using this method, devices having smaller than conventional contact structures can be readily interconnected.

Abstract: Pb-free solder alloys based on the Sn-In-Zn system (exemplarily 86:5:9 weight %) are disclosed. Compositions can have a melting temperature in the range 183.degree. C..+-.10.degree. C. and thus can be readily substituted for conventional 40 Pb-60 Sn solder. The novel compositions also can possess superior mechanical properties, compared to the 40/60 Pb-Sn composition, and readily wets copper. Bi and/or Sb may be added to the Sn-In-Zn base to reduce the tendency for the formation of lower temperature phases.

Abstract: A diamond body, such as a CVD diamond film, is thinned by placing the body--at an elevated temperature and under pressure--in contact with a molten or partially molten alloy of a rare earth metal and a metallic impurity that lowers the melting point of the rare earth metal. Typically, the rare earth metal is cerium and the impurity is nickel.The pressure is typically less than approximately 0.2 MPa (Mega Pascal), preferably less than approximately 0.02 MPa, and the temperature is within a range whose lower limit is approximately 100 C. degrees below the melting point of the alloy of the rare earth plus impurity metal.

Abstract: Metals useful in the formation of hydrides for applications such as batteries are advantageously activated by hydriding/dehydriding process. This process involves repeatedly stepping the potential of metal/metal hydride electrodes in electrochemical cells. The process activates hydrogen-storing materials that are difficult to activate by conventional means.

Abstract: Materials of composition La.sub.v X.sub.w M.sub.y Mn.sub.z O.sub.x, with x selected from Mg, Sc, Al, Zn, Cd, In and the rare earths that have an ionic radius smaller than that of La, with M selected from Ca, Sr, Ba and Pb, and with v, w, y, z and x in the ranges 0.45-0.85, 0.01-0.20, 0.20-0.45, 0.7-1.3 and 2.5-3.5, respectively, can have substantially improved magnetoresistance (MR) ratios, as compared to the corresponding X-free comparison material. In particular, the novel materials in polycrystalline (or non-epitaxial thin film) form can have relatively large MR ratios. For instance, polycrystalline La.sub.0.60 Y.sub.0.07 Ca.sub.0.33 MnO.sub.x had a peak MR ratio in excess of 10,000% (in absolute value) in a field of 6 T.

Abstract: In accordance with the invention, a new type of microphone utilizes a magnetoresistive sensing element. Specifically, acoustical energy causes vibrations between a magnetoresistive element and a magnet, producing a variation in the resistance which can be used to convert an acoustical signal into a corresponding electrical signal.
