Abstract
PURPOSE:To interrupt and remove the flux leakage and a beat of the transformer by covering the whole surface except the bottom of the transformer with a shape having the volume resistivity of specified value and the porosity and thickness of specified value or higher. CONSTITUTION:The case having the 50,000OMEGA.cm or lower volume resistivity, the 20% or higher porosity and 5mm. or thicker thickness is manufactured by molding and solidifying or sintering conductive powder, such as metallic powder, carbonaceous powder, carbide powder, etc., and the whole surface except the bottom of the transformer is covered with the case. Accordingly, the flux leakage and beat of the transformer used for an amplifier for an audio circuit can be interrupted and removed.
