    • Ferrite Synthesis 

      Vinal, Francis E. (Lincoln Laboratory - Division 6, 1953-09-15)
      A systematic investigation of the MgO•MnO•Fe[subscript 2]O[subscript 3] system has indicated that rectangular hysteresis loops can be obtained over a wide range of composition. Maximum squareness is obtained in the region ...

    • Ferrite Synthesis II 

      Vinal, Francis E. (Lincoln Laboratory - Division 6, 1954-02-17)
      The systematic investigation of the MgO-MnO-Fe₂O₃ system for which preliminary results were reported in Memorandum M-2442, has been extended and verified. The patterns of loop squareness vs. composition have remained ...

    • Polishing Specimens of Ferrites 

      Vinal, Francis E. (MIT Digital Computer Laboratory, 1952-10-14)
      Phase relationships in ferrite bodies and correlation with loop squareness and other electrical and magnetic properties have raised questions about polishing specimens for photo-micrographic and thin-section study. This ...

    • Trip to RCA Victor, Camden, October 22, 1953 

      Vinal, Francis E. (Lincoln Laboratory - Division 6, 1953-10-28)
      Review of the progress in memory core production at RCA Victor in Camden is encouraging but considerable stabilization remains to be accomplished in the process, particularly in the pressing and firing operations. Particular ...

    • Visit to IBM, October 23, 1953 

      Vinal, Francis E. (Lincoln Laboratory - Division 6, 1953-10-28)
      The Tube Laboratory at IBM under Mr. John Little has received the assignment of investigating ferrite memory core production. During the past summer, the study was initiated and although the project is not as yet fully ...

    • Visit to RCA Victor in Camden, January 14, 1953 

      Vinal, Francis E. (MIT Digital Computer Laboratory, 1953-01-22)
      The writer visited the RCA Victor Ferrite Plant and development Laboratory in Camden, N. J., and was favorably impressed by their staff's feeling for the problem as well as the facilities available in the laboratory. They ...
