The RAYDENT treatment technology was born by Ken Ogawa in December 1964 in Kyoto, using the name Reidento (Cold Electroplating) Industry Co., Ltd. (now RAYDENT Industry), and it is Japan's original and purely domestic technology. It has become well known as precision rust inhibiting treatment since then and has spread over the whole country with the rise of the semiconductor industry.
The founder Ken Ogawa came from Takada-gum, Hiroshima Prefecture, and was engaged in research into aircraft engines and lubricating oil at the former Aeronautical Research Institute of Tokyo Imperial University in Mitaka City, Tokyo, before the war. After that, he worked as the director of a former pine oil (aircraft lubricating oil) refinery until the end of the war. (We hear secondhand that he was the inventor of a glass communicating tube liquid level meter that is now widely used.)
