But there are many undesirable factors which affect the frequency stability of Onpen Oscillator. One who desires to use Onpen Oscillator at its best condition, must understand the character of these factors. In this paper the outlines of all kinds of these factors are treated and the counter-measures for them are mentioned. When the Onpen Oscillator is operated with great carefullness for these factors, it is not difficult to keep the frequency stability in figures 10{ v ~10{ w over a long period., Article, 信州大学工学部紀要 7: 147-158 (1957)}, pages = {147--158}, title = {音片発振器の周波数安定度に及ぼす諸要因}, volume = {7}, year = {1957} }
