Prior Experience

In my previous job at the car manufacture, I engaged in research and development of compressors used in air-conditioner for vehicle. Through this experience, I have gained comprehensive and practical knowledge in material mechanics, fluid dynamics, and thermal dynamics, all of which are necessary to design vapor-compression air conditioners and compressors.

I have also acquainted with mechanical processing, molding, and press working which are essential knowledge to manufacture compressors. My knowledge has been further enhanced by the work, including knowledge of refrigeration cycle which is necessary to assess air-conditioners, knowledge of noise and vibration, knowledge of fracture mechanics which is necessary to assess durability, etc.

Having engaged in such development of compressors, I myself was involved in numerous Japanese and foreign patent filings as an inventor. These patent applications are now granted patents in Japan as well as foreign countries. The invention of one of these patents has been highly and effectively utilized and successfully contributed to development of the regional industry. As a result, I could receive the Incentive Award of Chairman of Patent Attorneys Association.
