Some Applications of Magnetic Film Parametrons as Logical Devices

Ferromagnetische dünne Schichten (VI) 9. Anwendung in statischen Speicherelementen und in Schaltnetzwerken

“…J e nach Polaritat des maguetischen Vor-Adders, eines Schiebezahlers und eines Schieberegisters. POHM, READ, STEWART und SCHAUER ([49] und[50]) weisen darauf hin, daB auch das Schichten-Parametron bei geeigneter Aussteuerung dreier stabiler Zustande fahig sein kann (schwingt mit der Phase 0, schwingt mit der Phase n und schwingt trotz Erregung nicht). Mit der Existenz dieses ternaren Schaltelementes diirften die Untersuchungen der dreiwertigen Logik wieder an Bedeutung gewinnen.…”

Energy transfer properties of thin magnetic film logical elements

“…At x = 0, both form should have the same peak value, implying that a =a ltd (21) Note that the integral over all x of the function given by Equation 20 is equal to p, which says that the total flux represented is equal to that emanating from the top line pole and closing on the bottom line pole, a logical result.…”

“…ii The thin magnetic film with uniaxial anisotropy has been for several years the subject of intensive research in regard to its application in various types of electronic devices. A wide range of rather diverse appli cations including balanced modulators (18,20), parametric amplifiers (18,19), and paramétrons (14, 18,21) have been investigated but by far the most intensive work has gone into the use of such an element as a simple switching element in digital computer storage and logical systems. Memory applications are most numerous (l, 2,13,15,16,17), although promising applications to computer logic (7,9) have also been proposed.…”
