Abstract
Abstract This invention involves the resilient suspension of a quartz oscillator in a casing. Resilient suspension members are provided between the nodal joints of the quartz and the casing and damping members are disposed so as to damp and limit the displacement of the quartz under conditions of shock.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
134 words
A resonator device, comprising a casing, a quartz crystal oscillator, a plurality of resilient members for holding said oscillator for free oscillation in said casing, and a plurality of damping means for limiting the displacement of said oscillator within said casing under the influence of shocks, each resilient member being fixed at one end to a pin located in the wall of said casing, and at the other end to a second pin soldered to a nodal point of said oscillator, each second pin extending from the corresponding nodal point along the corresponding nodal axis; and each of said damping means including a rigid end fixed to said casing and a resilient end surrounding said second pin, the stiffness of said resilient end being greater than the stiffness of each of said resilient members.
Claim 2
Dependent Claim
