Title: Inductance element of fabric structure
Inventor: KOBAYASHI YOSHIAKI
IPC: H01F17/00
Filed: 1990-10-31
Abstract: PURPOSE:To prevent the inductance and the Q value from being deteriorated due to a microstructure and to enable the element to be used at a high frequency by a method wherein a twisted wire having an overall pseudosquare cross section and composed from coated conductors is used as an excitation conductor. CONSTITUTION:As an excitation conductor 3, a polyvinyl formal coated copper wire whose cross section is circular is worked to be pseudosquare by using multistage roller. Consequently, although a conductor resistance is the same, the interval between excitation conductors 3 can be narrowed and this system is suitable for a microstructure. On the other hand, the opposite area between a magnetic core 2 and the excitation conductor 3 becomes the same or small as compared with a case where a circular excitation conductor is used, and this element can be used at a high frequency. Since the length of the magnetic core 2 can be made short while the number of turns is the same, the inductance per unit magnetic core is increased. When a plurality of thin coated wires having a circular cross section are twisted and used, the excitation conductor 3 and the magnetic core 2 come into contact with each other at a small face, the capacity is made small and the element can be used at the high frequency.
