摘要： An inductor includes a wire including a conducting line, and an insulating film disposed on an entire circumferential surface of the conducting line, and a magnetic layer embedding the wire. The magnetic layer contains a magnetic particle. The magnetic layer includes a first layer in contact with the circumferential surface of the wire, a second layer in contact with the surface of the first layer, . . . and the n-th layer (n is a positive number of 3 or more) in contact with the surface of the (n−1)th layer. In the two layers adjacent to each other in the magnetic layer, the relative magnetic permeability of the layer closer to the wire is lower than the relative magnetic permeability of the layer farther from the wire.

摘要： Forming a ferrite thin film laminate includes heating a layered assembly to form a laminate. The layered assembly includes a first coated substrate having a first ferrite layer opposite a first thermoplastic surface and a second coated substrate having a second ferrite layer opposite a second thermoplastic surface to form a laminate. Each coated substrate is formed by forming a ferrite layer on a surface of a thermoplastic substrate. The coated substrates are arranged such that the first ferrite layer contacts the second thermoplastic surface. Heating the layered assembly includes bonding the first coated substrate to the second coated substrate such that the first ferrite layer is sandwiched between a first thermoplastic substrate and a second thermoplastic substrate. The ferrite thin film laminate may include a multiplicity of coated substrates.

摘要： A reinforcing underlayment including dry uniform particles evenly applied to a wet bonding material layer on a surface of a substrate. The substrate, including the layers, is then cured to harden the one or more of the layers. A final coating or topcoat is applied to the cured surface of the substrate. The dry particles are evenly distributed onto the bonding material layer creating a uniform surface for subsequent coatings. The dry particles increase the strength of the liquid coatings increasing solid particle density within the coating system and thereby imparting properties not available for the liquid coatings. The present invention enables a user to easily introduce very heavy, dense, strong particles into a liquid coating and allows the user to apply very dense, heavy particles into and onto a wet bonding material layer followed by a subsequent wet topcoat layer which is cured as one contiguous material with reinforcement and underlayment strengthening coming from the added, dry particles.
