Latest Patents

One of his latest patents is a cylinder device that features a unique stopper mechanism. This mechanism includes a second cylinder located at the end of an inner cylinder, along with a second piston that moves in conjunction with a piston rod. The design allows for the second piston to be fit-inserted through the second cylinder. The second piston is equipped with a stopper that is coupled to the piston rod, and it incorporates a castle that is integrated with the stopper through plastic flow. This design creates a ring groove on the outer periphery of the second piston, allowing for a piston ring to be fixed within the groove. The piston ring is displaceable in the axial direction and is retained in the groove, showcasing a sophisticated engineering approach.

Another notable patent involves a fastening method for securing a nut to a bolt through screwing. This method includes preparing a nut with a tool mounting portion on its seat surface and an annular thin portion opposite the seat surface. The process involves swaging multiple areas of the thin portion with punches from the outer circumferential direction. This technique allows the thickness of the thin portion to extend partially to the front end of the bolt, ensuring a close adherence to the screw portion of the bolt.
