Abstract : The story of the silicon carbide function switch and function switch blanks is related in Section I of the report. The section, entitled 'Nonlinear Switching Elements', demonstrates that the asymmetric resistance characteristics of diode rectifiers are not essential to their application as switching elements, and that any two-terminal passive network possessing a suitable symmetric, nonlinear, voltage-current characteristic curve may be employed as a switching element. Section V on the 'Morphology of Electronic Circuits' comprises a discussion of the possibility of using flat sheets of passive and active elements in the fabrication of electronic circuits. Section II entitled 'Optical Elements for Computers' summarizes certain advantages to be gained by employing light pulses rather than electrical pulses for the handling of digital information. Efforts are underway to produce bistable optical elements for the storage of digital information. Section III is a first report on activities pointed in this direction. Section IV deals with the design and construction of a coded-decimal multiplier and, more generally, with a technique for the storage of a function of two variables. Section VI contains some data on the spectral distribution of the light emitted by an electroluminescent phosphor. (Author)
