内容記述 | The main frequency adjusting methods of the tuning bar osicilltor are clasfied into amplitude control method, phase control method, and stiffness control method. As one of the stiffness control method, the frequency of the tuning bar can be adjusted by changing the control current which flows the control coil attached close by the tuning bar. However, it is great mistake to expect, as is generally supposed, that when control current increases, the frequency decreases affected by the magnetization of control coil. The truth is that, in certain condition the frequency increases, while in other condition decreases. This phenomena is due to mainly the method of arrangement of polarities of magnetic coils and control coil. The most proper arrangement of the polarities of the coils for the purpose to change the frequency in one direction with increasing control current, is the one which is called "" symmetrical arrangement center equal polarity"" In this paper, the state of frequency change of the tuning bar due to the method of arrangement of polarities of the coils, and the effects upon the tuning bar which, is produced by the control coil are described. | |||||
