<p>PURPOSE:To reduce a distributed capacity of individual coils of a rotary transformer and to improve a high-frequency characteristic by a method wherein adjacent conducting wires are wound at interval nearly equal to a diameter of a conductor and both ends of the coils are pierced through small holes made in grooves of a magnetic substance core which houses the coils and are extracted from faces opposite to faces where the grooves have been formed. CONSTITUTION:Conducting wires forming individual coils 3p to 3s are wound at intervals nearly equal to a diameter of a core wire. As a result, a distributed capacity of the individual coils 3p to 3s is reduced, and a high-frequency loss at the individual coils 3p to 3s is reduced. The conducting wires at winding start parts and at winding end parts of the individual coils 3p to 3s are extracted immediately from the winding start parts and the winding end parts to faces opposite to faces where grooves 6a to 6d have been termed. Accordingly, the extracted conducting wires do not cross any coils; even when a plurality of coils simultaneously run on a tape, it is possible to suppress an unnecessary crosstalk. Thereby a high-frequency characteristic can be enhanced.</p> |
