<p>The thermo compensated resonator comprises a body (15) used in deformation. A core of the body is formed by a first material. A part of the body comprises a paramagnetic or diamagnetic coating made of shape-memory metal. Variations in the Young's modulus of body as a function of the temperature are in opposite sign to coefficient of thermal expansion of the first material used for the core so as to allow the resonator to have a frequency variation as a function of the temperature, which is zero to a first order. The core of the body comprises quartz. The thermo compensated resonator comprises a body (15) used in deformation. A core of the body is formed by a first material.

Variations in the Young's modulus of body as a function of the temperature are in opposite sign to coefficient of thermal expansion of the first material used for the core so as to allow the resonator to have a frequency variation as a function of the temperature, which is zero to a first order. The core of the body comprises quartz. The body comprises a section having a quadrilateral shape, where completely coated faces of the quadrilateral shape are identical in pairs. The coating forms a barrier against humidity. The body includes bars, which are coiled together to form a balance spring and a tuning fork and are coupled to a flywheel.</p> |
