Abstract

PURPOSE:To make the device small-size and high-performance, by simplifying the case and using the center conductor as a leader line as it is. CONSTITUTION:A ferrite core 6b is put on a soft magnetic substance 12 used as an earth conductor also through a shield plate 15b. Three center conductors 13 which have cross parts insulated from one another are provided on the ferrite core 6b. Another ferrite core 6a is put on these conductors 13, and a shiled plate 15b is covered. A permanent magnet 3 which applies the magnetostatic field to the ferrite core is put on the shield plate 15b. A fitting metallic jig 24 is provided to cover the whole of these parts and is fixed by screws 17. Center conductors 13 become strip lines as they are. The fitting metallic jig is provided with openings for leader lines. Generated heat is discharged to the lower part from the soft magnetic substance 12 easily.
