CA 2283963

A piezo-oscillator reduced in current consumption and size, comprising a crystal oscillator as a piezoelectric vibrator, an oscillation circuit, a plurality of surface mounted heaters, and a temperature control circuit for controlling the heating temperatures of the heaters, all mounted on a printed circuit board, wherein the case and lead terminals of the piezoelectric vibrator are simultaneously heated respectively by separate heaters so that the piezoelectric vibrator, the oscillation circuit and the temperature control circuit can be heated at the same time.

Cet oscillateur piézo-électrique qui consomme moins de courant et qui est de taille réduite, comprend un oscillateur à cristal comme vibrateur piézo-électrique, un circuit d'oscillation, plusieurs éléments chauffants montés en surface, et un circuit de commande de température servant à commander les températures de chauffage des éléments chauffants, le tout monté sur une carte à circuit imprimé. Le boîtier et les bornes des conducteurs du vibrateur piézo-électrique sont chauffés simultanément, respectivement par des éléments chauffants séparés, pour que le vibrateur piézo-électrique, le circuit d'oscillation et le circuit de commande de température puisse être chauffés en même temps.
