PURPOSE:To make easy the adjustment of coupling, by alternately coupling a plurality of coils on a pair of bobbin holders. CONSTITUTION:A plurality of coils 3 are allocated and a capacitor 6 is fixed under the holders 1, 2. Coils 32, 24, 26 are fixed to the holder 1 and coils 3, 33, 35 are fixed to the holder 2. A separator 15 is inserted among the bobbins 3, 33, 35. Thus, the gaps of each bobbin are closed by being determined with the separator, allowing to achieve high coupling. Further, since the adjustment of coupling can be made by keeping the coil gaps equally through the movement of the bobbin holders, excellent pulse characteristics can be obtained. |
