Title: **Koichi Sakamoto: Innovator in Rotary Machine Technologies**
Introduction
Koichi Sakamoto, a prominent inventor based in Tokyo, Japan, has made significant contributions to the field of rotary machines. With a total of six patents to his name, Sakamoto is recognized for his innovative approaches in improving the performance and efficiency of rotary devices.
Latest Patents
Sakamoto's recent patents include a "Rotary Machine State Observation Device," "Rotary Machine," and "Rotary Machine State Observation Method." The state observation device utilizes an analog-to-digital converter (ADC) to digitize detection signals from a gap sensor during low-speed sampling periods. It further employs a separation unit that distinguishes between vane detection signals—indicative of the compressor impeller's vanes—and non-vane detection signals. By analyzing and comparing these signals, the determination unit extracts a vane peak detection signal, allowing for the assessment of shaft vibrations and tip clearances in the compressor impeller. This innovative system enables the monitoring of rotary machine states without necessitating high-speed sampling.
