RESONATOR WITH MATCHED BALANCE SPRING AND BALANCE Russian patent published in 2018 - IPC G04B17/22 

FIELD: clocks and other time meters.

SUBSTANCE: invention relates to resonator (1) comprising balance spring (5) formed of a quartz monocrystal with crystallographic axes x, y, z, where x is the electric axis and y is the mechanical axis, and interacting with balance (3). According to the invention, coefficient (α_b) of balance (3) temperature expansion is from +6 million^-1 °C^-1 up to +9.9 million^-1 °C^-1, and angle (θ) of balance spring (5) cutoff with respect to the z axis of the quartz monocrystal is from -5° up to +5° in order to match balance (3) with balance spring (5).

EFFECT: clock resonator is proposed.
