Title: Daichi Kosugi and Lubricant Supply Control
Introduction
Daichi Kosugi is an inventor based in Kanagawa, Japan, whose patent work addresses the monitoring and control of lubrication in mechanical devices. He is associated with NSK Corporation and is credited with 1 patent.
Latest Patents
Kosugi is named on the patent “Method for Controlling Supply of Lubricant, Device for Controlling Supply of Lubricant, and Program.” The invention describes measuring the impedance of an electric circuit that includes multiple lubricated portions by applying an AC voltage. It uses the measured impedance to derive oil-film thickness and the rate of oil-film breakage, then adjusts the lubricant supply amount or timing to achieve a predetermined lubrication state.
Career Highlights
The patent reflects an approach to lubrication control that uses electrical measurements to assess oil-film conditions and guide lubricant delivery. This can help a device respond to changing lubrication needs across multiple portions.
Collaborations
Taisuke Maruyama and Tomoyuki Matsuda are listed as Kosugi’s coworkers.
Conclusion
Daichi Kosugi’s patent work at NSK Corporation focuses on using impedance measurements to inform lubricant supply and maintain a desired lubrication state.
