Filed: 1986-10-01
Abstract: PURPOSE:To prevent the generation of large eddy currents in case of high-fre quency operation, and to improve the high-frequency characteristics of a mag netic core by separating a magnetic thin-film into a plural ity of layers by means of resistance layers having comparatively small resistivity. CONSTITUTION:A magnetic wire 1 used for a magnetic core for an inductance element is constituted in such a manner that layers consisting of magnetic thin-films 3 having high permeability such as permalloy and resistance layers 4 having small resistivity are formed alternate ly onto the whole surface of a long-sized sheet 2 composed of a metallic conductor such as copper foil and the outside of the whole is covered with an insulating film 5 made up of an epoxy resin, etc. The resistivity of the resistance layer 4 is selected from a range to 10<2>muOMEGA.cm from 10<6>muOMEGA.cm. Accordingly, not only the magnetic thin-films 3 can be shaped thinly in multilayers but also each layer is isolated electrically by the resistance layers, thus largely reducing loss by eddy currents, then acquir ing the small-sized inductance element having excellent high-frequency characteristics.

IPC: G01P3/488
Filed: 1989-09-11
Abstract: PURPOSE:To provide a light and smaller detector by forming a circuit for inducing electromotive force, which is printed on an insulation film. CONSTITUTION:A magnetic flux generated with a permanent magnet 3 is large when a tooth tip of a pulse gear 1 made of a ferromagnetic material passes therethrough and small when a tooth bottom passes therethrough and a change in the magnetic flux causes an electromotive force to be induced by an AC wave or a pulse wave.

Thus, as a circuit 4 for induction of electromotive force is made up of printed circuits 41 and 42 printed on an insulation film 40 differing from the conventional type having a coil provided in the perimeter of a permanent magnet thereby achieving a light and a smaller circuit.
