Ways to improve the efficiency of automatic control systems of pressing current collectors for railway service of high speeds by A. S. GOLUBKOV, O. A. SIDOROV, S. N. SMERDIN

“…With increasing operation speeds, the dynamic loads on the current collector from the rolling stock increase and the aerodynamic impact increases as well, which leads to an increase in the variation of the contact pressure, tearing off the current collector from the contact wire, arcing in contact and increased wear of the contact elements. …”

Thermal Load Influence during the Formation of Al-Al Contacts on the Electrical Parameters of the Integrated Circuits with Aluminum-Polysilicon Contacts by V. A. Pilipenko, V. A. Solodukha, N. S. Kovalchuk, J. A. Solovjov, D. V. Shestovski, D. V. Zhyhulin

“…An analysis of the currentvoltage characteristics showed that they are all identical, except for the course of the direct branch of the base current value from the emitter-base voltage. The deviation of the linear nature of this dependence in the region of their low voltage values (£ 200 mV) in the case of the formation of ohmic Al-Si and Al-Al contacts with the use of long-term heat treatments is due to the predominance of the generation-recombination current in this region associated with an increased density of traps in the depleted region and on the surface of the semiconductor. …”
