Title: Kunio Furukawa: Innovator in Seismic Response Technology
Introduction
Kunio Furukawa is a notable inventor based in Kanagawa, Japan. He has made significant contributions to the field of seismic response technology, particularly through his innovative patent that addresses the challenges posed by earthquakes. His work is essential for enhancing the safety and resilience of structures in earthquake-prone areas.
Latest Patents
Furukawa holds a patent for a high damping device designed for seismic response controlled structures. This hydraulic cylinder type device connects a cylinder member or a piston rod member to the frame of a structure, while the other member is linked to an earthquake-resisting element secured to the frame. The invention features multiple passages through the piston that connect hydraulic chambers on opposite sides, equipped with pressure-governing valves to control oil flow. An accumulator system allows for oil to bypass between hydraulic cylinders, modulating oil pressure in the damping device. Additionally, relief valves work in parallel with the pressure governing valves to provide a variable damping coefficient, protecting the device from overloads due to excessive seismic shocks. Furukawa's patent is a testament to his innovative approach to improving structural safety.
