内容記述 | The oscilltor which has the highest frequency stability, at the range of audio frequency,is the one which is controlled by mechanical vibrator as tuning bar or tuning fork. However,when the vibrator is exposed in the atomesphere,the frequency stability is affected by the change of atomospheric pressure,and this effect is unable to neglects,if higher frequency stability is demanded. To insulate from the effect of atomospheric pressure change,the vibrator is sealed in vacume vessel at present. But this vacuume sealed vibrator has some troubles at practice use as the folliowing:(1)the resonance frequency of vacuume sealed vibrator becomes much higher than the one in the atomosphear, and the adjusting of the frequency becomes difficult,(2)having the vacuume vessel is not suitable to the simplification of the oscillator,(3)the taking in and out of the virator, and the handling or the making of the device are not easy. Against the vacume sealed vibrator,author enclosed the vibrator in mere airtight vessel,which is not vacuume,to separate from the effect of the atomospheric pressure change,and for the temperature effect,by selecting the value of the temperature coefficient of frequency of the vibrator as to cancel the frequency change,which depends upon the atomospheric pressure change inside of the vessel due to the temperature change, the effective temperature coefficient of the frequency of the whole closed vibrator device was reduced to negligible small. By employing the closed type tuning bar oscillater,which depends upon the above mentioned principle,the troubles of the vacuume sealed vibrator were desolved,and the frequency stability was remarkably improved,namely for example,the frequency was maintained constant over one month to better than 7 to 10,000,000 without any adjusting. | |||||
