Introduction

Naohiro Ota is an inventor based in Tokyo, Japan, associated with Hitachi Industrial Equipment Systems Co., Ltd. His patent work addresses air compressor design and maintenance.

Latest Patents

Ota is credited with 1 patent, titled “Air compressor.” The invention concerns a packaged, air-cooled compressor with separate cooling paths for the cooler and motor. It uses two cooling-air intake ports, a fan, and an outlet to move air through the system and exhaust it after cooling the components.

A controller compares the temperatures of bearings at the motor shaft’s anti-load and load sides, positioned upstream and downstream in the cooling-air flow. If the temperature difference falls below a threshold, the controller determines that the cooler is clogged. This approach is intended to recommend cooler cleaning at an appropriate time while limiting additional costs.

Career Highlights

Ota’s documented patent highlights his contribution to compressor monitoring and maintenance. The design uses bearing-temperature differences as an indicator of cooler clogging, supporting timely cleaning recommendations.

Collaborations

Ota’s listed coworkers include Yuuji Itou and Takehiro Matsuzaka. The available information identifies his association with Hitachi Industrial Equipment Systems Co., Ltd., but does not specify their roles in the patent.

Conclusion

Naohiro Ota’s patent focuses on detecting cooler clogging through temperature monitoring, offering a practical approach to maintaining packaged air-cooled compressors.
