Abstract: A method of fabricating a high-temperature bobbin for a solenoid or other electrical assembly includes the step of providing a bobbin configured for use in the assembly. The bobbin is coated with an anti-oxidation composition and an anti-corrosion composition to produce an oxidation/corrosion resistant bobbin. The oxidation/corrosion resistant bobbin is coated with an electrical insulating composition that is resistant to corona discharge at or below a predetermined voltage threshold to produce an insulated and oxidation/corrosion resistant bobbin. The anti-oxidation composition, the anti-corrosion composition, and the electrical insulating composition can withstand temperatures of subzero up to temperature greater than 1000° F.

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.

Abstract: A superconducting device includes a first superconducting wire configured to carry a first current in a superconducting state, and to generate thermal energy upon occurrence of a hot spot during conduction. The device includes a second superconducting wire, thermally coupled to and electrically isolated from the first superconducting wire. The second superconducting wire is configured to conduct a second current in a superconducting state below, but sufficiently near its critical surface to be quenched to a non-superconducting state upon conduction of the thermal energy from the first superconducting wire.

Abstract: A filter component assembly kit includes a bobbin that is configured with first and second members and a core that is in a quadrangular frame shape. When the first member is assembled with the second member, a through hole is formed in the bobbin. The through hole extends in a first direction. The core is configured with first and second extension bars. The first and second extension bars extend in parallel in the first direction. When the first extension bar is disposed in the through hole of the bobbin, rotation of the core around the first extension bar is prevented. First allowance of the first extension bar in a second direction, which is perpendicular to the first direction, in the through hole is larger than second allowance of the first extension bar in a third direction, which is perpendicular to the first and second directions, in the through hole.

Abstract: The present invention is a superconducting partial insulation magnet and a method for providing the same. The magnet includes a coil with a non-insulated superconducting wire winding wound around a bobbin. The coil has a first wire layer, a second wire layer substantially surrounding the first layer, and a first layer of insulating material disposed between the first wire layer and the second wire layer. Each wire layer comprises a plurality of turns, and the first layer of insulating material substantially insulates the second wire layer from the first wire layer.

Abstract: A transformer having a plastics coil former on whose hollow winding tube (7) between flanges (3, 5) windings (11, 13) of different potentials are wound with one winding wound on top of the other. The flanges (3, 5) are provided with spacers (17, 19, 23) to keep the windings (11a, 13a) axially spaced from the flanges (3, 5). An insulating layer (21), which extends from flange to flange, is interposed between the windings (11, 13). The winding (11) nearer the coil-former axis is spaced from the flanges (3, 5) by fixed spacers or stepped portions (17, 19) provided on the winding tube (7). The winding (13) arranged on the insulating layer (21) is spaced from the flanges (3, 5) by spacing blocks (23) which are connected to the flange areas (24) of the coil former by integral hinges (25). The spacing blocks are operable for swinging down onto the insulating layer (21).

Abstract: A bobbin wound coil for an electromagnetic coupling includes a bobbin having a cylindrical body, end flanges disposed at opposite ends of the body and a terminal connector defining a central cavity bordered, in part, by inner and outer walls and a side wall extending between the inner and outer walls. A coil has a beginning portion extending through first openings in the inner and outer walls, an end portion extending through second openings in the inner and outer walls, and a center portion wound about the bobbin body. The first and second openings in the inner wall divide the inner wall into first and second circumferential end sections and a center section. A portion of one of the circumferential end sections and the center section is spaced from the side wall to define a recess configured to receive one of the beginning and end portions of the coil.
