Title: Ryo Ota and Hydraulic Fluid Management in Construction Machinery.
Introduction
Ryo Ota is an inventor associated with Hitachi Construction Machinery and based in Chiyoda-ku, Japan. His listed patent addresses hydraulic fluid maintenance in construction equipment. Ota is credited with 1 patent.
Latest Patents
Ota’s patent, “Construction machine,” describes a hydraulic excavator designed to help extend the intervals between hydraulic fluid replacements. The system includes an additive tank, a supply line, an on-off valve, an oxidation sensor, and a controller.
The sensor monitors the degree of oxidation in the hydraulic fluid. When the oxidation rate reaches a predetermined threshold, or when a specified period of machine operation has elapsed since the fluid was replaced or the valve was last closed, the controller either reports that the valve should open or opens it. This allows additive to flow into the hydraulic fluid tank.
Career Highlights
Ota’s listed invention focuses on monitoring fluid condition and managing additive delivery. By responding to oxidation measurements and operating time, the system is intended to support hydraulic fluid upkeep and reduce the frequency of fluid replacement.
Collaborations
Ota is associated with Hitachi Construction Machinery. His listed coworkers include Daigoro Kamoto and Kenji Kawasaki.
Conclusion
Ryo Ota’s patent presents a sensor-guided additive system for construction machinery, with the goal of maintaining hydraulic fluid and extending replacement intervals.
