Abstract (in Japanese) (See Japanese page) 
(in English) Authors have studied the influence on contact resistance by actual micro-oscillation to electrical contacts using some oscillating mechanisms in the vertical direction. In this paper, the authors discussed the difference of time-sequential fluctuations in the contact resistance when contact frictional force between male-pins and female-pins were “usual”, “smaller” or their “middle”, using hammering oscillating mechanism. It was shown that the contact resistance was increasing and fluctuating under the “middle” friction. In comparison to micro-sliding mechanism, it was indicated that the difference of the contact frictional force was related to degradation phenomenon of electrical contacts and there was relative displacement between male-pins and female-pins by oscillations using hammering oscillating mechanism with 150G.
