As an Applications Engineer at Shockley Transistor Corporation, Gene was responsible for designing and
building “demo units” to be used at trade shows and conventions to
demonstrate the potential uses of the 4-layer diode technology. The top photo shows a recent “Demonstrator
Kit”, built for display at the TransistorMuseum. Gene indicates that this audio oscillator, using a basic “sawtooth circuit”, is similar to the
style he used 45 years ago in his first job at Shockley. The scan on the left is a section of one
the patents issued to William Shockley for 4-layer (PNPN) diode applications. This patent demonstrates the possible use
of the diode as the active element in
a phone switching circuit. Gene
remembers building a demo unit for this application too. It was hoped by the
company that this use of the diode would lead to orders for millions of the
4-layer diodes by Western Electric to replace the mechanical switches in use
at the time.
