Latest Patents

Iizuka's latest patents include an anti-earthquake bearing apparatus and a safety monitoring method for use in active seismic response and wind control. The anti-earthquake bearing apparatus is designed to bear the weight of a structure while reducing the vibration energy that propagates to it. This is achieved through the use of spherical bag-like bearing bodies, which are formed by sealing a fluid, rubber-like solid, or gas into bags made from a rubber-sheet material reinforced with fiber. Each bag-like bearing body is equipped with charging and discharging ports, and the design includes recesses to prevent positional shifts.

The safety monitoring method is intended for use in systems that control seismic response and wind effects. It measures the work done by a seismic response control force and determines whether the control is functioning correctly. If any abnormalities are detected, a stop signal is generated to halt the system, ensuring the safety of the structure.
