Title: Shigeki Nakaminami: Innovator in Damping Technology
Introduction
Shigeki Nakaminami is a notable inventor based in Tokyo, Japan. He has made significant contributions to the field of damping technology, holding a total of 3 patents. His innovative designs focus on enhancing the performance and efficiency of damping devices.
Latest Patents
One of Nakaminami's latest patents is an eddy current damper. This device includes a screw shaft, first and second permanent magnets, a cylindrical magnet holding member, a cylindrical conductive member, and a ball nut that meshes with the screw shaft. The screw shaft is designed to move in the axial direction, while the first permanent magnets are arranged circumferentially around it. The second permanent magnet is positioned between the first permanent magnets, with an inverted arrangement of magnet poles. The conductive member is placed opposite the first and second permanent magnets, creating a gap between them. The ball nut is located inside the magnet holding member and the conductive member, and it is fixed to either of these components.
Another significant patent is a damping device that consists of a fixed cylinder, which is attached to a first structural body and has a hollow portion. A shaft member, fixed to a second structural body, is housed within the hollow portion and features a helical thread groove on its outer surface. A nut member engages with the shaft member, converting axial motion into rotational motion. Additionally, a rotor member encases the fixed cylinder, forming a cylindrical accommodation chamber filled with a viscous fluid.
