かった。There was a problem that the viscosity was high and it was difficult to install. In addition, when winding the wire around the core, the terminal must be fixed near the electrode on the back of the core, which complicates the structure of the winding machine. Especially when winding multiple coils, it is necessary to attach the terminals one by one. The yield was poor because of the need to
