Dyson is a well-known maker of ring-shaped bladeless fans, but which Japanese company invented them, in 1981?
Bladeless fan A bladeless fan (sometimes called an air multiplier) blows air from a ring with no external blades. Its blades are hidden in its base. The first concept was created by Toshiba in 1981.

Mitsubishi FBR Systems Mitsubishi FBR Systems, Inc. (MFBR) is a company formed on July 1, 2007 by Mitsubishi Heavy Industries to develop Fast breeder reactor technology. The establishment of the company was based on the April 2007 decision by the Japanese government to select Mitsubishi as the core company for FBR development. Expectations are for a demonstration reactor for launching by 2025 and a full commercial plant by 2050, and for FBRs to eventually supersede Light water reactor technology in Japan.
