A Comparison Between Square-Loop Metals and Ferrites for High-Speed Pulsed Operation
(Lincoln Laboratory - Division 6, 1954-02-04)
Metals and ferrites with rectangular hysteresis loops are used in magnetic amplifiers, switching networks, and data-storage systems. In these applications, the large-signal pulse response is most important. To reduce the ...
The cryotron - a superconductive computer component
(Lincoln Laboratory - Division 6, 1955-08-22)
Tne study of nonlinearities in nature suitable for computer
use has led to the cryotron, a device based on the destruction of superconductivity by a magnetic field. The cryotron, in
its simplest form, consists of a straight ...
Trip Report: Trip to IRE, Bell Telephone Laboratories, Glenco, Naval Ordnance Laboratory, Professor Pulvari, Cavitron, Mullard, RCA, and NSA, March 23-31, 1954.
(Lincoln Laboratory - Division 6, 1954-04-13)
A trip was made to various laboratories investigating ferroelectric and ferromagnetic materials for information storage and switching. Information is listed by topics.
Trip to Burroughs Research Center, Paoli, Pennsylvania, Tuesday, April 27, 1954
(Lincoln Laboratory - Division 6, 1954-04-27)
A trip was made to the Burroughs Research Center to discuss magnetic-core computer components and fabrication of metal cores. They are planning to make and improve metal cores and they have used magnetic cores in logical ...
Special Display
(MIT Servomechanisms Laboratory, 1950-10-04)
Memorandum from project Whirlwind research teams on control of the special display for electronic digital computers.
Nondestructive Sensing of Magnetic Cores
(MIT Digital Computer Laboratory, 1952-03-24)
A "Nondestructive" method for sensing the information state of magnetic-memory cores is under development. This new method involves the use of a quadrature magnetic field which, when pulsed, produces an output voltage. The ...
Ferroelectrics for Digital Information Storage and Switching (Abstract of R-212, a Master's Thesis)
(MIT Digital Computer Laboratory, 1952-11-20)
This memorandum contains the abstract of Report R-212, a Master's Thesis, by Dudley A. Buck.
First-Order Cancellation Residue in Rectangular Memory Arrays
(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 ...
An Investigation of Ferroelectrics for Digital Information Storage
(MIT Department of Electrical Engineering, 1951-11-23)
Master's Thesis Proposal: An Investigation of Ferroelectrics for Digital Information Storage.
Trip to Linde Corporation, Tonawanda, New York, August 17, 1953, to Discuss Growth and Procurement of Ferrite Single Crystals
(Lincoln Laboratory - Division 6, 1953-09-08)
The Linde Corporation is growing ferrite single crystals by the Verneuil process. They are of interest to this laboratory for basic studies of the switching mechanism of ferrites.
