Abstract: A shim system for influencing and homogenizing the magnetic field of an NMR system includes a coil former (1), an extension tube (2) and a terminal unit (3), as well as partial coils (4, 4a) that are mounted on the coil former. Terminal lines (6a, 6b) for connecting the partial coils to the terminal unit are initially electrically disconnected from one another between the coil former and the extension tube. A circuit board (5) with connection lines (5a, 5b, 5c, 5d), however, is interposed between the disconnected terminal lines. This makes it possible to redesign the shim system in the mechanical construction thereof using simple technical measures and standard components, and without giving rise to significant additional costs. Therefore, production of the partial windings on the coil former can take place in a simplified, economical and automated manner, without requiring an extension tube to be already fitted.

Abstract: An electromagnetic coil with improved insulation properties at high temperatures. A bobbin is insulated by a thin ceramic composite layer that is produced by winding a glass or ceramic fiber over the support structure and impregnating it with a pre-ceramic polymer. The pre-ceramic polymer is then modified to form a ceramic SiO2 matrix around the fibrous layer. The ceramic matrix secures the glass or ceramic fibers in place and produces a dense layer. A ceramic coated magnet wire is then wound around the insulated support structure. The magnet wire is a conductor that is spiral-wrapped with a glass fiber impregnated with a pre-ceramic polymer.

Abstract: One aspect is for a method of manufacturing a magnetic coil for a magnetic actuator. A coil carrier is provided which comprises a tubular section and a collar which adjoins the tubular section, wherein the coil carrier is arranged for accommodating a coil winding. A die comprising a defined inner contour is provided which is adapted to the coil carrier. The coil carrier is inserted into the die, wherein the collar of the coil carrier rests on a seating surface of the die. The collar is punched with a punch, wherein a flange contour is formed at the collar the outline of which is defined by an inner contour of the die. The coil carrier is also at least sectionally potted or overmolded with a filler material, wherein the flange contour provides a barrier for the filler material. The disclosure further relates to a corresponding magnetic coil.

Abstract: A non-contact power reception apparatus is provided, in which a power reception coil for a charging system and a loop antenna for an electronic settlement system are mounted on a battery pack and a cover case of a portable terminal such that the power reception coil is arranged in the center thereof and the loop antenna is disposed outside the power reception coil, so that a mode of receiving a wireless power signal and a mode of transmitting and receiving data are selectively performed, thereby preventing interference from harmonic components and enabling non-contact charging and electronic settlement using a single portable terminal. A jig for fabricating a core to be mounted to the non-contact power reception apparatus is provided.
