Technical Consultant

Takayasu Tahara, Ph.D.

Almost 50 years experiences as an internationally recognized expert in the areas of pressure equipment engineering, material, design, fabrication, research and testing , especially, heavy wall hydrotreating reactors for petroleum refining since 1964 when he joined the Japan Steel Works, Ltd.. He has used that expertise toward the betterment of ASME Codes and Standards and related research activities in the development of “real practicable engineering solutions” and able to translate them into ASME Code requirements. In this regard he has been an ASME member since 1996, and an International Delegate to the ASME Boiler and Pressure Vessel Code Committee, since 2004 and also nominated as ASME Fellow in 2009. He has also made major contributions on the recent ASME Division 2 rewrite, Post Construction Repair and Testing, Fitness-for-Service projects, and ASME PVP OAC . In API , almost 25 years of contribution as a member, API/ASME T/G on Fitness-For-Service, API T/G 582 WPS, API T/G934 Cr-Mo Materials for Heavy Wall Pressure Vessels
Ph.D. (1997), Tokyo Institute of Technology

Fujio Oishi, Ph.D.

His specialty is researching the durability of polymeric materials and their application in industrial fields such as railways. He was engaged with the Railway Technical Research Institute for 26 years, in Japan National Railways for the first 23 years and in Foundation supported by JR Group companies for the next 3 years. He invented the “C-type Life Estimation Method” as research, moreover applied polymeric materials on “Tohoku-Jyoetsu Shinkansen” and “Linear Motor Car System” as development.
He was invited to be a professor at the faculty and graduate course of science at Kanagawa University, he started teaching polymeric material science and technology, and other subjects in 1990. During that period, he pursued research in the durability of polymeric materials and responded to the requirements from about 80 companies.
In 2010, he became a professor of emeritus at Kanagawa University. An Eco (Ecology) Business Leader Course was established at Teikyo University due to his proposal. He was teaching environmental science as a professor together with other 5 lecturers, leading ECO(Ecology) Business Leader Course. He is a guest professor of Teikyo University, also he is a visiting professor of Qingdao Science and Technology University. He introduces and demonstrates the practical implementation of new technology & new materials to companies which want to innovate by applying his method of “SNJ (seeds & needs joint technology)”.
Ph.D. (1983), Tokyo Metropolitan University.
Award:The Environmental Agency and the Polymer Society of Japan.
Writing: “Durability of Plastics”, “Durability of Polymeric Materials”, and other about 20 books.
