Latest Patents

Tetsuya Tomizawa holds a patent for a "Damping device and vibration control apparatus for structure." This device utilizes the moment of inertia of a flywheel and the adjustable resistance force of a viscous magnetic fluid. It allows the viscous magnetic fluid to exert its properties even without an external power source. The design includes a sleeve with an attached ball nut that reciprocates within a first cylinder. This motion is converted into rotational motion by a ball screw, which rotates a flywheel in a second cylinder and a generator rotating shaft. A sealed space containing a viscous magnetic fluid is formed between the flywheel and the inner surface of the second cylinder. Additionally, a magnetic field generating unit is positioned on the inner circumference of the second cylinder to create a magnetic field across the sealed space.
