Nippon Telegraph and Telephone Corporation has succeeded in fabricating a novel ultrasonic oscillator by applying a principle analogous to an optical laser, which is widely used as a highly purified light source, to a microelectromechanical systems (MEMS). The frequency purity of the output vibration is less than 1 part in1,000,000.
