1940

Dec. 1940 The Japan Science Council reported then Government to recommend the policy to apply hard chrome plating on the low grade steel as the alternative to high grade one, such as special steel or high-speed steel, under the difficult external trade conditions to get them, the invention, Patent No.131175 (1937), “the method to deposit hard and thick metal chrome plating” by Minoru Araki, the former president of Company, being as the technical foundation. It was followed by the request to establish a specialized company of hard chrome plating (industrial chrome plating) from National Headquarters of Aviation, Sagami Arsenal, and customers,
  • Minoru Araki, Former President,
  • Hideo Fujita, Former Managing Director of Nichiro Fishery Co., Ltd.,
  • Yoshinosuke Ando, First President, Former Managing Director of Shoei Corp.,
