Title: Innovations of Shinji Ishimaru in Vibration Suppression Technology.
Introduction
Shinji Ishimaru is a notable inventor based in Sohka, Japan. He has made significant contributions to the field of vibration suppression technology, holding a total of 3 patents. His work focuses on creating structures that effectively mitigate vibrations, particularly in multi-storied buildings.
Latest Patents
One of his latest patents is a vibration suppressing structure that includes a main structure and a vibration suppressing section. This section is positioned in the upper portion of the main structure and features an auxiliary structure designed to respond to vibrations caused by disturbances. The system incorporates an auxiliary mass, a driving device, and a damper. The displacement of the auxiliary structure due to vibrations is transmitted to the auxiliary mass through the driving device. The auxiliary mass is controlled in a manner that is directly proportional to the displacement amount. The design of the vibration suppressing section ensures that the damping coefficient of the damper, the magnitude of the auxiliary mass, and the ratio of the movement of the auxiliary mass to the displacement of the auxiliary structure are optimized. This results in a system capable of effectively suppressing vibrations while maximizing the use of space within the structure.
