Abstract: A superconducting coil according to the present disclosure includes: a substrate having a first surface and a second surface; a superconducting layer having a third surface and a fourth surface; respective stabilization layers; and respective protective layers. The second surface is opposite to the first surface. The fourth surface is opposite to the third surface. The superconducting layer is disposed on the substrate such that the third surface faces the second surface. The respective stabilization layers are disposed on the first surface and the fourth surface. The respective protective layers are disposed on the stabilization layers. Adhesion strength between each of the stabilization layers and each of the protective layers is lower than strength of the superconducting layer.
Abstract: A uniform thickness flex circuit is taught that uses more than one dielectric layer. A first dielectric layer is more flexible and capable of reliably bending at a radius of curvature at which a second dielectric layer cannot be reliably bent. The second dielectric layer has at least one more desirable electrical characteristic than the first dielectric area, for example leakage. Use of the uniform thickness flex circuit to protect sensitive material in an electronic enclosure is also described.

Abstract: The invention provides the system supporting variable speed drive comprising a three-sided service cabinet embodiment. The cabinet comprising two heat exchange circuits limited by the basic elements of the cabinet embodiment, the first of which is configured to interact with an external environment and with the second heat exchange circuit, wherein the second heat exchange circuit which is configured without an ability to interact with the external environment includes a sealed cell for installing power electronics and the cell for installing a power connection and the cell for installing a measurement equipment. The cabinet comprising a dust and moisture filter, a plate heat exchanger, and a moisture removal device. The cabinet may be assembled with joined end-to-end metal sheets with curved joined ends which form strengthening ribs.
Abstract: The present invention relates to a cable jacket comprising a random heterophasic propylene copolymer, wherein said copolymer comprises a matrix (M) being a random propylene copolymer (R-PP) and dispersed therein an elastomeric propylene copolymer (E), wherein the random propylene copolymer (R-PP) has a melt flow rate MFR2 (230° C./2.16 kg) of 0.1 to 10.0 g/10 min and wherein the elastomeric propylene copolymer (E) has a comonomer content in the range of 40.0 to 55.0 mol %, and wherein said copolymer has MFR2 (230° C.) in the range of from 0.5 to 15 g/10 min, flexural modulus below 400 MPa, and relaxation spectrum index (RSI) at 200° C. below 20.0. The present invention further relates to a telecommunication cable comprising said jacket.
Abstract: A weld nugget portion that is obtained by welding a central conductor of a wire and a receiving portion of a metal terminal is formed on the receiving portion that receives an end portion of the wire with the weld nugget portion expanding from a surface of the receiving portion along which the wire is disposed. An area ratio of a blowhole to a section of the weld nugget portion that is along an imaginary cut plane that is perpendicular to the surface of the receiving portion along which the wire is disposed is no less than 0% and no more than 8.4% (i.e., from 0% to 8.4%), preferably no less than 0% and no more than 1.3% (i.e., from 0% to 1.3%). A central axis of the central conductor of the wire in the weld nugget portion extends along the imaginary cut plane.

Abstract: An eddy current energy-dissipating spacer is mainly composed of a spacer frame, a conductor clamp and energy-dissipating elements. The eddy current energy-dissipating spacer not only provides the function of an ordinary spacer, but also reduces the vibration of the transmission lines; and at the same time, can effectively reduce the vibration of the transmission lines, especially the torsional vibration by adopting the eddy current and viscoelastic material for energy dissipation; improves the eddy current strength by adjusting the gear radius ratio, thus increasing the damping force; can adjust the damping parameters by adjusting the magnetic field strength of the permanent magnet; can produce long-term stable vibration reduction effect by adopting the permanent magnet to provide continuous magnetic field without additional external energy input; can effectively avoid the magnetic flux leakage of magnetic circuits by adopting the magnetic material.
