Latest Patents
One of Uda's latest patents focuses on the electrofusion of electrofusion joints. This invention includes an electrical heating wire embedded in the inner peripheral region of the joint, which can be fitted to the end of a plastic pipe. By supplying electrical current to the heating wire, the interface between the joint and the pipe is fusion bonded. To facilitate easy determination of the completion of fusion bonding, the electrofusion joint is designed with an annular groove on its outer peripheral surface, extending to a region near the heating wire. A pin or bar-like core member is positioned at the center of the groove, with a stopper member above it to control the extent of projection. This design allows for confirmation of successful fusion bonding through the observation of the movement of the stopper member, which is influenced by the pressure from the flow of molten resin. Additionally, as the stopper member is lifted by this pressure, the electrical contact is broken, terminating further heating.
