Title: Ryoji Sasaki: Innovator in Vibration Detection Technology
Introduction
Ryoji Sasaki is a notable inventor based in Tokyo, Japan. He has made significant contributions to the field of vibration detection technology, holding a total of 3 patents. His work focuses on improving the efficiency and reliability of machinery through innovative detection methods.
Latest Patents
Sasaki's latest patents include a contact vibration detection device and a vibration suppression method for turbochargers. The contact vibration detection device is designed to detect contact vibration resulting from the interaction between a rotational shaft and a stationary part. It features a rotation waveform determination unit that analyzes the displacement of the rotational shaft during operation. Additionally, it includes a parameter change detection unit that identifies changes in the effective value or phase angle of the rotation waveform. The device ultimately determines the occurrence of contact vibration based on these parameters.
The vibration suppression method for turbochargers aims to mitigate shaft vibration in motors. This method involves determining whether the rotor shaft is in a specific vibration state and whether the motor is in an excited state. If the rotor shaft is in a specific vibration state and the motor is not excited, the method applies an exciting voltage to the motor to suppress vibration.
