  • Mechanically-coupled tuning fork-scanning probe vibrating system
    Patent number: 8087093
    Abstract: Provided is a mechanically-coupled tuning fork-scanning probe vibrating system, the system including: a tuning fork vibrating due to an AC voltage applied thereto; a scanning probe attached to a side of the tuning fork and vibrating due to the tuning fork; and a contact member contacting a side surface of the scanning probe and adjusting a position of a contact point at which the contact member contacts with the scanning probe, to vary a natural frequency of a combination body in which the tuning fork and the scanning probe are combined with each other.
    Type: Grant
