Abstract:
Vergussmasse geeignet zum Vergießen eines Elektronikbauteils, insbesondere einer großvolumigen Spule wie einer Gradientenspule, bestehend aus einer Trägermatrix, in welcher wenigstens ein Füllstoff aus polymeren Nanopartikeln verteilt ist, wobei in die Trägermatrix (8) wenigstens ein als Flammschutzmittel dienender Füllstoff (11) eingebracht ist.
Abstract:
The present invention relates to a Continuously Transposed Conductor (2), comprising several identical strands (20) which are connected up parallel to the ends, each strand (20) successively and repeatedly taking on every possible position inside the whole conductor cross-section. According to the invention, each strand (20) is a subset comprising at least two wires of rectangular cross section firmly joined together by a joining coating to form said subset. Wires within a subset may be arranged either flat by flat or side by side.
Abstract:
An electronic component-use substrate and an electronic component being higher in relative permittivity than conventional materials, free from reduction in strength, small in size, higher in performance and excellent in general electric characteristics; an electronic component-use substrate and an electronic component being restricted in lot-to-lot variations of electric characteristics, especially relative permittivity, and restricted in wear of a metal mold when a material is molded; and an electric component being high in withstand voltage; wherein an electronic component-use substrate and an electronic component comprise a composite dielectric material in which a dielectric having at least circular, oblate circular or oval projection shape is dispersed into resin.
Abstract:
The present invention relates to an insulated electric cable (8) that has one or more conductors (4). With the intention of reducing the winding space, improving cooling, reducing stray flux and therewith improving the efficiency of apparatus and devices that include cable windings, the insulation of the cable in the cable winding has been given a varying thickness. The concept of providing the electric cable with insulation that varies in thickness can be utilised with both AC-cables and DC-cables. Moreover, the nature of the voltage concerned need not be decisive in the manufacture of the cable. The thickness distribution of the insulation may be linear (11) or non-linear (12), depending on the adaptation to the desired field strength distribution. The invention enables smaller, fewer and more effective apparatus and devices to be constructed.
