Latest Patents

Ishida's latest patents include an anti-vibration apparatus for seismic acceleration and an earthquake isolation floor. The anti-vibration apparatus is designed to reduce seismic acceleration by utilizing X-axis direction linear motion means that are horizontally displaceably mounted on rails. This system incorporates Y-axis direction rails and tension springs to support both upward and downward loads. The machinery mounting platform can also pivotally carry another platform through articulated lever mechanisms, providing additional support during seismic activities.

The earthquake isolation floor features a horizontal plate-like support frame with a polygonal configuration. It includes a smaller support frame that is slidably mounted on the fundamental frame. Horizontal tensile springs are placed between the two frames in a prestressed condition, allowing for movement during an earthquake while maintaining stability.
