Title (EN) METHOD FOR ADJUSTING VIBRATION FREQUENCY OF TUNING FORK TYPE VIBRATOR,AND APPARATUS THEREFOR
(FR) METHODE DE REGLAGE DE LA FREQUENCE DE VIBRATIONS D"UN VIBRATEUR DU TYPE A DIAPASON DE SYNTONISATION, ET APPAREIL POUR CETTE METHODE
Abstract: front page image
(EN)A method and a device for adjusting the vibration frequency of a tuning fork type vibrator to a desired frequency. The method comprises the steps of adjusting the vibration frequency of a tuning fork type vibrator to a frequency of a predetermined value lower than a desired frequency, then adjusting the difference between the natural vibration frequencies of the two tine-portions of the tuning fork vibrator below a predetermined value and further adjusting the vibration frequency to the desired frequency, while maintaining the difference in the natural vibration frequencies below the predetermined value. The method enables rapid adjustment to the desired frequency.
(FR)Une methode et un dispositif de reglage de la frequence de vibrations d"un vibrateur du type a diapason de syntonisation sur une frequence desiree. La methode comprend les etapes de reglage de la frequence de vibrations d"un vibrateur du type a diapason de syntonisation sur une frequence d"une valeur predeterminee inferieure a une frequence desiree, puis l"ajustement de la difference entre les frequences de vibrations naturelles des deux branches du vibrateur du type a diapason de syntonisation en-dessous d"une valeur predeterminee, et a ajuster la frequence de vibration a la frequence desiree, tout en maintenant la difference des frequences de vibrations naturelles inferieure a la valeur predeterminee. La methode permet l"ajustement rapide a la frequence desiree.
