摘要： A transformer that improves the DC superposition characteristic without incurring eddy-current losses. In the transformer, a part of a plate-like core opposing a top face of a flange of a drum core is formed with a first opposing portion opposing none of input and output terminals and a second opposing portion opposing the input and output terminals. A first gap is formed between the top face and the first opposing portion by a spacer. A second gap greater than the first gap is formed by a recess of the plate-like core provided so as to correspond to the second opposing portion. This allows magnetic fluxes to pass between the top face and the first opposing portion where the gap is formed and inhibits them from passing between the plate-like core and the input and output terminals where the second gap greater than the first gap is formed.

摘要： A noise filter providing a simplified construction and capable of being used regardless of a diameter of a cable or a numbers of cables. The noise filter includes a core-holding section for holding a core, first and second cable-guiding sections, and two coupling sections coupling the first and second cable-guiding sections to ends of the core-holding section. The first and second cable-guiding section have truncated conical shape, and each divided into the four parts by a first to fourth slits arrayed in cruciform shape whose crossing position is coincident with an imaginary apex of the cable-guiding section. The coupling section has first to fourth circumferential elongated slots in communication with the proximal ends of the first to fourth slits.
