| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | We developed the mechanism which gives vibration to electrical contacts by hammering and studied the influences of a micro-oscillating on these. Over 2.5 millions of hammering, the resistance of the contacts started increasing. Over 4 millions of hammering, the resistance often exceeded 200Ω. And over 7 millions of hammering, this fluctuated between 175Ω and 570Ω. On the other hand, we also developed the mechanism which gives sliding to electrical contacts for comparison. This mechanism could detect the degradation phenomenon on these by influences of repeated sliding operations. Over 17 thousand of sliding, the resistance of the contacts started increasing, and after that the resistance fluctuated in between 20Ω and 250Ω. Although the two mechanisms are completely different( in methods, numbers, etc ), the results of two test were almost similar on the oscillational phenomenon. |
