Patent number: 7469603Abstract: An angular velocity detector using a vibrator made of an annular thin film. The detector also has electrodes arranged ingeniously to have high detection sensitivity for angular velocities. The detector can detect angular velocities in two axial directions simultaneously. The detector has support portions (1105), (1106) which are formed over a first substrate (1123) and poised above the surface of the first substrate (1100) at a certain spacing therefrom. Resilient support bodies are supported to the support portions and include outer springs (1102) and inner springs (1103). A vibrator (1101) is mounted via the resilient support. An exciting means consisting of a magnet (1124) and an exciting electrode (1108) excites the vibrator to vibrate in a certain direction of vibrations.Type: GrantFiled: October 20, 2004Date of Patent: December 30, 2008Assignee: Sony CorporationInventors: Masaya Nagata, Hiroshi Nishitake, Koji Fukumoto, Kazuhiro Matsuhisa, Atsuhito Yasui
