Abstract:
(EN) A portable clock is provided with an atomic oscillator (13) for generating and outputting a reference clock signal; and a clock module (12) which operates based on the reference clock signal. The atomic oscillator (13) and the clock module (12) are separately arranged to be thermally isolated. An electronic device is provided with a crystal oscillator for generating and outputting a first oscillation signal; an atomic oscillator for generating and outputting a second oscillation signal which is more accurate than the first oscillation signal; a clock module which operates based on the first oscillation signal and the second oscillation signal; and a thermally isolating section for thermally isolating an atomic oscillator, the crystal oscillator (11) and the clock module (12). Thus, the portable clock and the electronic device wherein influence of heat from the atomic oscillator is reduced and power consumption can be reduced, even when the atomic oscillator is used as a reference oscillator, are constituted.
(FR) La présente invention concerne une horloge mobile comprenant un oscillateur atomique (13) qui génère et produit un signal d’horloge de référence et un module d’horloge (12) qui fonctionne selon le signal d’horloge de référence. L’oscillateur atomique (13) et le module d’horloge (12) sont agencés indépendamment pour leur isolation thermique. Un dispositif électronique comprend un oscillateur à quartz qui génère et produit un premier signal d’oscillation, un oscillateur atomique qui génère et produit un second signal d’oscillation plus précis que le premier, un module d’horloge qui fonctionne selon le premier signal d’oscillation et le second, et une unité d’isolation thermique qui isole thermiquement l’oscillateur atomique, l’oscillateur à quartz (11) et le module d’horloge (12). On peut ainsi former une horloge mobile et un dispositif électronique permettant de réduire l’effet thermique de l’oscillateur atomique et la consommation d’énergie, même si l’oscillateur atomique sert d’oscillateur de référence.
(JA)  基準クロック信号を生成し出力する原子発振器13と、基準クロック信号に基づいて動作する時計モジュール12と、を備え、原子発振器13と時計モジュール12とは熱的に分離すべく別体に配置される。また、第1発振信号を生成し出力する水晶発振器と、第1発振信号よりも高精度の第2発振信号を生成し出力する原子発振器と、第1発振信号および第2発振信号に基づいて動作する時計モジュールと、原子発振器と、水晶発振器11および時計モジュール12とを、熱的に分離する熱的分離部と、を備える。これにより、基準発振器に原子発振器を用いた場合でも、その発熱の影響を低減しつつ、消費電力を低減可能な携帯時計および電子機器を構成できる。
