Heretofore, the usual method of adjusting of frequency of the tuning bar oscilltors is the one which is worked by hand, for example observing the Lissajous figure produced by cathode-ray tube. This method, however, is unsuitable for the purpose of quick and precise adjustment. The main component elements of the newly developed system are tuning bar filter, amplitude limitter, frequency mixer, frequency control coil which attached close by the tuning bar,etc. If there is any difference in both frequency,the beat frequency is obtained at the output of the mixer. After the beat current is rectified and changed to direct current,this rectfied current flows into control coil. The frequency of the tuning bar changes due to the changing of the control coil,and is automotically synchoronized to the standard frequency, and then the rectfied current becomes certain constant value. Now, by flowing the same value of direct current as that rectfied current into the control coil, by turning ti the another direct electric source, the synchoronization of both frequency is completed quickly and precisely., Article, 信州大學紀要 (2): 149-153(1952)}, pages = {149--153}, title = {対標準関波数調整装置}, volume = {2}, year = {1952} }
