Latest Patents

One of his latest inventions is the damping coefficient switching-type hydraulic damper. This device can automatically switch its damping coefficient without requiring external energy. It ensures a greater energy absorption capacity compared to typical hydraulic dampers. The mechanism involves a piston that moves in a specific direction, utilizing a mechanical drive composed of a straight gear and a crank mechanism. This allows for an on-off control operation valve to be placed in a closed state, switching the damping coefficient to a maximum value (Cmax). When the piston moves in the opposite direction, the valve opens to eliminate load, switching the damping coefficient to a minimum value (Cmin). This process is repeated to achieve effective seismic response control.

Another significant patent is the attenuation coefficient switching-type hydraulic damper. This device is designed to reduce shaking in structures during earthquakes. It features a cylinder, a reciprocating piston, hydraulic chambers, and a single on-off control valve. The damping coefficient changes based on the valve's state, allowing for effective control of the damper's performance. A mechanical drive attached to the piston rod operates the control valve, ensuring optimal functionality.
