Researchers find new way to predict end of metal life cycle

OSAKA, Japan - Researchers at Osaka University said March 2 they have discovered how to predict the end of the life cycle of metal, paving the way for technology which may prevent accidents resulting from metal fatigue. Prof. Masahiko Hirao said his team has discovered that metal becomes more likely to absorb oscillations shortly before it nears the end of its life cycle. A microscopic photo shows the surface of a metal bar which is in a state to absorb high-frequency oscillations.

    Professor Tetsuya Yamamoto and his colleagues at Kochi University of Technology and the Technical Research Institute of Sumitomo Heavy Industries, Ltd. have developed a technology that can change the characteristics and add functions to oxide semiconductors in the same equipment after stabilizing them using negative oxygen ions in the deposition process. The process is a highly efficient way to create negative ions of oxygen in a plasma thin film deposition system and attract them to the substrate side by applying a voltage. Prof. Yamamoto is also scheduled to deliver a keynote speech on this theme at an international conference on film formation technology hosted by a German film formation equipment manufacturer in March 2008.

      Aichi Sangyo (Shinagawa-ku, Tokyo) and Shibaura Institute of Technology have started a joint research project to manufacture mass-produced products using metal 3D printers. Aichi Sangyo (Shinagawa, Tokyo) and Shibaura Institute of Technology have started a joint research project to manufacture mass-produced products using metal 3D printers. Overseas, mass production using metal 3D printers has already started, but in Japan, it is still in its infancy. In Japan, 3D printers are mostly used for prototyping and development, but not for mass production, because of the risk of internal problems during molding and the low accuracy of surface finish. Measurement and evaluation methods for processed materials have not been established in Japan. Therefore, through joint research, they will try to solve these problems.

          TOKYO, Japan - A new low-noise wind power system that can adapt to changes in wind direction and continue rotating is set to hit the market in Japan for public use. Kazuichi Seki, professor of a Tokai University science and technology research center and a member of a team that developed the system, said similar research on the development of such windmill-shaped generators has been done abroad but that this is the first time such a system has been put to practical use.
