The structure of these high-precision gyros is generally a uniaxial degree of freedom integral rate gyro, in which a float with a gyro motor sealed in a cylindrical case is provided, and a liquid is filled in the cylindrical outer case. The float is supported by the float, and the float is damped by reducing the frictional torque of the bearing that rotatably supports the float and by utilizing the viscous resistance of the liquid.

Conventional temperature control devices such as gyros use heating elements (heaters).
Heat-resistant insulators are sandwiched with heat-resistant insulators, and a band heater made into a film is wrapped around the case, or the heater wire is covered with an insulator and wrapped in a coil around the outside of the outer case. The special heater is expensive,
Insulators deteriorate over time, and the heating element does not come into close contact with the case that controls the temperature, creating void layers in places, resulting in poor thermal conductivity and uneven temperature (non-uniformity). It has its drawbacks.

There were drawbacks as a high-precision gyro temperature control device, such as the inability to accurately detect temperature.
