Abstract (in Japanese) (See Japanese page) 
(in English) Authors have developed some mechanisms which give real vibration to electrical contacts and studied the influences of a micro-oscillating on the contact resistance. Because it was necessary to deal with time-sequential data for analyzing the degradation phenomena of electrical contacts by the oscillating mechanisms, they tried to use non-linear data processing in addition to usually linear one. It is shown that there are semi-stable limit cycles and bifurcation phenomenon in the time-sequential fluctuation using phase plane analysis by raw data themselves. It is indicated that there is some differences between data by rectangular input and those by sinusoidal one using phase plane analysis at neighboring lower limits of the amplitudes of the oscillation. And it is suggested that there is possible to reproduce quasi-limit cycle and quasi-bifurcation by using the combination of some of fundamental waveforms.
