<p><P>PROBLEM TO BE SOLVED: To provide a transformer which performs efficiently its heat radiation while reducing the noise leaked from a gap portion formed in its core. <P>SOLUTION: In the transformer wherein a gap portion 2 is formed in its core 1, and as the means for intercepting the noise radiated from the gap portion 2, it is so constituted by winding a short ring 3 around both its core 1 and bobbin 4 as to cover the gap portion 2 therewith, it is further so constituted by winding the short ring 3 a plurality of times that the short ring 3 functions as a heat radiating means too. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
