Patents by Inventor Hiroshi Nishitake

Hiroshi Nishitake has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Angular velocity detector, method of detection of angular velocities using angular velocity detector, and method of fabricating angular velocity detector
    Patent number: 7469603
    Abstract: 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.
