Latest Patents
One of Hatano's latest patents is focused on a joint structure and joining method. This invention involves a joined assembly that includes a first member and a second member, which has a facing part directed towards the first member. The assembly features joints along the facing part that connect the two members. The design includes a pair of end joints located at the opposite ends of the facing part, along with an intermediate joint that has a lower joining strength than the end joints. The end joint utilizes a fastening member to mechanically join the two members, while the intermediate joint employs a friction-stirred part for joining through friction stir.
Another notable patent is related to a friction stir spot welding method and a welded assembly utilizing this technique. In this invention, a first member made from a thermoplastic resin mixed with fiber material is welded to a second member composed of a thermoplastic resin. The process involves using a double-acting tool for friction stir spot welding, where the tool is positioned against the overlapping part of the two members. The pin is plunged into the overlapping area, allowing for friction stir to occur, which preserves extension fibers around the plunging region.
