Most manufacturers are fully aware of the need to develop new businesses based on competitive technologies, thus they are actively exploring business applications of their accumulated expertise in the firms. They build up efforts for enhancing technology commercialization, for example, new energy technologies to solve environmental problems, or security technologies to contribute to safety and a comfortable society. Meanwhile, in the case of developing new businesses based on emerging technologies which do not exist so far, the anticipated markets for the application do not arise as expected at all. For example, even though the markets of mobile fuel cell, optical interconnection, or carbon nanotube are expected to grow rapidly within the next few years, they have kept still almost at the same position.
