1,089,106. Tunnel diodes. COMPAGNIE GENERALE D'ELECTRICITE. May 27, 1966 [May 31, 1965], No. 24046/66. Heading H1K. [Also in Divisions H3-H5] A pulse generator arrangement suitable for supplying adjustable current pulses for use in the manufacture of tunnel diodes, comprises a trigger pulse generator 4 controlling an adjustable monostable flip-flop 5, the resulting pulse from which is applied via amplifier 7 to adjustable resistance network 8-12 to provide a pulse of desired amplitude to preamplifier 14 and high internal resistance power amplifier 15. As shown in the embodiment, switches 2 and 13 are used to provide first a small pulse to weld an aluminium wire 16 to a germanium body and then one or more intense pulses to alloy the aluminium and germanium to provide a tunnel diode D with desired characteristics; the characteristics are measured with meter 18 in between applied pulses. |
