Title: **Koji Nishimoto: Innovating Seismic Isolation Technology in Tokyo**
Introduction
Koji Nishimoto is a prominent inventor based in Tokyo, Japan, with an impressive portfolio that includes 23 patents. His work primarily focuses on advanced seismic isolation devices, which are crucial in enhancing the safety and stability of structures during earthquakes.
Latest Patents
One of his latest inventions, the sliding seismic isolation device, is a sophisticated mechanism designed to minimize the impact of seismic activity. This device features a structure fixation plate with a first sliding surface in contact with a metallic slider comprising a second sliding surface. A notable aspect of this invention is the friction member crafted from a single-layer fabric that incorporates high-strength fibers along with PTFE fibers. The fabric undergoes a unique weaving process, ensuring that the plied yarns are more exposed at the surface than the high-strength fibers. This innovation provides an efficient sliding motion during seismic events.
Additionally, he developed another model of a sliding seismic isolation device that consists of an upper shoe and a lower shoe, each with uniquely curved sliding surfaces enhancing the device's effectiveness. Between these shoes lies a columnar steel slider that is integral to the device's ability to absorb shocks. The upper and lower surfaces of the slider are covered with a double-woven fabric layer, containing PTFE fibers for improved performance. A fluorine coat layer and a lubricating oil layer are applied to further enhance its functionality, making these inventions pivotal in earthquake engineering.
