      Buck, Dudley A. (MIT Digital Computer Laboratory, 1952-04-16)
      A multi-position ferroelectric switch is proposed which can accomplish many of the switching tasks in an information handling system; in particular, it can select among rods and columns of a ferroelectric memory. The logical ...
    • Ferroelectrics for Digital Information Storage and Switching 

      Buck, Dudley Allen (MIT Digital Computer Laboratory, 1952-06-05)
      This report was originally issued as a thesis report and as such received but limited distribution. So as to extend the distribution to the many who have expressed interest in ferroelectric components for digital information ...

    • First Meeting of MIT-IBM Central Standards Committee 

      Watt, C. W. (MIT Digital Computer Laboratory, 1953-06-22)
      The committee met June 19, at MIT. Components Application Memos #1, #2, #3A, #3C, and #8, pf the Electronics Components Committee were approved in substance but are to be rewritten by IBM into an easily usable form.
    • First Meeting of the Planning Committee for the IRE-AIEE Conference on Electron Tubes for Computers 

      Youtz, P. (MIT Servomechanisms Laboratory, 1950-08-18)
      This is a report of the first meeting of the planning committee for the IRE-AIEE Conference on Electron Tubes for Digital Computers.
    • First Note on Pulse Transformers for Memory Drivers 

      Durgin, Frank; Gates, Earle (MIT Digital Computer Laboratory, 1953-05-27)
      It is possible to drive the coordinate lines of a magnetic-core memory plane with small-current-capacity vacuum tubes by using push-pull pulse transformers with large ratios of current transformation. A push-pull transformer ...
    • First-Order Cancellation Residue in Rectangular Memory Arrays 

      Buck, Dudley A. (MIT Digital Computer Laboratory, 1953-05-15)
      Aside from all second-order effects, there is an unwanted output voltage inherent in magnetic-memory arrays due to cores whose half-selected output voltages do not cancel. This voltage is due to two cores in the arrays ...
    • Fiscal '53 budget revision 

      Fahnestock, Harris. (MIT Digital Computer Laboratory, 1952-12-15)
