TriPreM (Tribology and Precision Machining i-Kohza) had a visitor from AIST (National Institute of Advanced Industrial Science and Technology) Japan. Dr. Abe is the authority on standard gas generation and measurement technology of humidity. He is also the co-inventor of the trace-humidity controller patent of mine which is granted in Japan. We discussed the possibility of collaboration work on humidity control technology between MJIIT and AIST.
