Latest Patents
One of his latest patents involves a method for manufacturing rectifiers. This innovation includes a heat dissipation heat sink that features a press-fit hole with an inner peripheral surface that is a cast skin surface. The heat dissipation heat sink is sandwiched by a press-fit head and an insertion guide. The alignment of the axis of a rectifying element in the insertion guide with the axis of the press-fit hole is crucial. The press-fit head faces the heat dissipation heat sink, while a protrusion portion of a load receiving jig is positioned to face the rectifying element in the insertion guide. The rectifying element is then press-fitted into the press-fit hole of the heat dissipation heat sink by applying pressure to the periphery of the press-fit hole, with the load being received by the protrusion portion of the load receiving jig.
