Thermocompensated resonator for use in electronic quartz watch, has body whose portion is arranged with metal coating whose Young's modulus is changed based on temperature so as to enable resonator to have variable frequency

摘要

The resonator (1) has a body part (5) that is able to be deformed, where the body is provided with a web. The web is formed by a material, and a portion of the body is arranged with a metal coating such as paramagnetic coating, whose Young's modulus is changed based on the temperature so as to enable the resonator to have a frequency that varies according to a first order temperature. The body is arranged with a section that is provided in the form of quadrilateral including faces that are arranged in an identical manner.
