  • Oscillator for time measurement
    Patent number: 3961209
    Abstract: This invention concerns an oscillator for time measurement, comprising a resonator the oscillation of which is maintained by at least one part reciprocated by electrostatic forces relative to at least one electrode connected to a direct voltage source, said part being periodically charged by contact with the electrode, or electrodes comprising an elastically deformable contact making member whose elastic deformation energy is much less when in contact with an electrode than the motional energy of the resonator.
