    Abstract: A method for improving thermal conduction in a stator having electrically conductive windings wound in a plurality of gaps formed between adjacent pairs of a plurality of teeth of the stator. A plurality of interstitial spaces are formed within each of the gaps during winding of the electrically conductive windings around the teeth. A plug is arranged within each one of the gaps to close off slot openings. A thermally conductive filler compound is injected into each gap under sufficient pressure to at least substantially fill the interstitial spaces within each gap and to at least substantially encapsulate the electrically conductive windings. The thermally conductive filler compound is then allowed to set.

    Abstract: The present application relates to a method of applying particles, an optical film and a method of manufacturing an active liquid crystal device. In the method of applying particles of the present application, the particles can be uniformly applied on a base material and fixed while maintaining the shape of particles. The optical film of the present invention produced by the above method can have excellent particle dispersity. A method of manufacturing an active liquid crystal device using the above method can maintain a cell gap uniformly while simplifying the manufacturing process and preventing gravity defects.

    Abstract: A coil component having a magnetic core, a bobbin accommodating the magnetic core, and at least one pair of coils wound around the outer part of the bobbin. The bobbin is implemented as a heat radiating member comprising: a polymer matrix; and graphite-nano metal composites which are provided in a plurality, are dispersed on the polymer matrix, and have nano-metal particles bonded to the surface of graphite. Accordingly, the heat generated from a coil component due to an applied current can most quickly and efficiently be conducted and radiated outside, and thus degrading of common-mode-noise rejection function is prevented and a differential signal can substantially be passed without attenuation. In addition, in spite of the heat generated from the coil component or external physical and chemical stimulation, heat radiating properties can last for a long time.
