Abstract: An electrical device in which a first connection element is in electrical contact with a resistive element. The first connection element defines a cavity into which, when the cavity is empty, a second connection element can be inserted. The second connection element, which may be connected to a source of electrical power, is partially within the cavity, makes physical and electrical contact with the first connection element, and protrudes from the cavity. Such devices can be made in a continuous process by a method of the invention. They are particularly suitable for insertion into a circuit board.

Abstract: A magnetoresistive write element having a planar coil layer between a first pole and a second pole. The magnetoresistive write element further includes a buildup insulation layer having an upper surface that is substantially coplanar with an upper surface of the first pole. Further, the planar coil layer is disposed above both the first pole and the buildup insulation layer. A method for forming a magnetoresistive write element includes providing a first pole and covering the first pole with an insulating layer. The insulating layer is then planarized, thereby exposing the first pole and defining a buildup insulation layer. This planarization also results in the formation of a substantially planar upper surface of the buildup insulation layer and a substantially planar upper surface of the first pole. More specifically, the first pole upper surface is substantially coplanar with the buildup insulation layer upper surface. The method also includes forming a write gap material layer above the insulation layer and first pole, and forming a substantially planar coil layer above said write gap material layer. In addition, a second pole is formed above the write gap material layer, with the coil layer thereby disposed between the first pole and the second pole.

Abstract: Polymers having low surface energy, e.g. fluorocarbon polymers, are rendered printable by conventional methods, e.g. offset printing, by incorporating a suitable particulate filler in the polymer, and shaping the filled polymer under conditions which result in the surface of the shaped polymer having irregularities which correspond to the particles of the filler. Suitable fillers comprise particles having at least two dimensions in the range of 1 to 40 microns; glass fibers are particularly satisfactory. Extruded insulating polymeric jackets for electrical components, e.g. strip heaters and wire and cable, can readily be marked by use of the invention.
