Title: Binary information magnetic storage system
IPC: H03K17/66
Filed: 1965-06-04
Abstract: 1,066,099. Magnetic information storage apparatus; transistor pulse circuits. SPERRY RAND CORPORATION. June 4, 1965 [June 8, 1964], No. 24026/65. Headings H3B and H3T. To eliminate history effects produced when the same information is re-recorded many times in succession in the same bit storage location in a magnetizable thin film memory, each bit drive pulse for writing-in is preceded by a pulse of opposite polarity. As shown in Fig. 3, a bit storage location 15 comprises the intersection of a word drive line 16 and a bit drive line 18 which is plated with a thin anisotropic permalloy film. For writing-in, the word driver 14 is energized and pulses A and B are applied consecutively to terminals 13, 15 of transformer T to induce in the secondary windings, and hence line 18, a first pulse of polarity dependent on whether the bi-stable multivibrator 4 is set or reset followed by a second pulse of opposite polarity which steers the magnetization of the element into a desired remanent stable state along its easy axis. Prior to any writing in operation, a positive pulse is applied to terminal 8 to reset the multivibrator 4 and then a positive information pulse may be applied to terminal 7 to set the multivibrator if required. In the absence of an information pulse, the multivibrator remains reset.

Title: Fet read-only storage matrix
IPC: G11C17/12
Filed: 1972-05-24
Abstract: 1340653 Semi-conductor devices INTERNATIONAL BUSINESS MACHINES CORP 24 May 1972 [5 June 1971] 24345/72 Heading H1K A read-only FET memory matrix includes, in an N (or P) type substrate 1, a plurality of parallel P (N) type bit line strips 2, 3 constituting common source regions for rows of memory cells whose drain regions comprise discrete P (N) type regions 7, 9, and parallel metal word line strips 5 perpendicular to the bit line strips 2, 3 and constituting the gate electrodes of the memory cells. The insulating layer 10 isolating the strips 5 from the substrate 1 and constituting the gate insulation of each wall is thinnest where it overlies the discrete P (N) type drain regions 7, 9 at 12, 14. This allows, for selected cells, a single 'write' process involving the application, between the selected word and bit lines, of a potential sufficient to induce breakdown of the thin portion 12 or 14 of the insulating layer 10, thereby to short the selected drain region 7 or 9 to the metal strip 5 and to charge the memory state of the cell. The channels of the individual cells may be restricted to the areas 16, 18 either by making the insulation 10 relatively thin over these areas, as shown, or by providing heavily-doped N<SP>+</SP> (P<SP>+</SP>) type zones elsewhere in the surface of the substrate 1. The "write" and "read" processes are described in detail, as in the conventional planar process used to manufacture the matrix.

Abstract: Nitro-compounds are prepared by treating ethylene or cyclohexene with nitrogen trioxide or nitric oxide, and oxygen or an oxygen-containing gas such as air, but excluding the process in which prior to contact with the olefine, the nitrogen oxide and oxygen or oxygen-containing gas are reacted together and in which the nitrogen oxide content of the reacted mixture is present as nitrogen tetroxide.  Nitration may be effected in the presence of a solvent of the type specified in Specification 580,260 or other solvents inert to the nitrogen oxides. Normally, anhydrous conditions are employed.  The nitrogen oxide and oxygen or air may be passed continuously through a solution of cyclohexene or ethylene or through liquid cyclohexene.  Ethylene, however, is preferably passed together with oxygen or air through the nitrogen oxides or solutions thereof.  The oxygen or oxygen-containing gas may be passed in at any stage of the process. The olefines used may contain diluents.  The products comprise dinitro-compounds, nitro/nitrates and nitrites.  To facilitate working up, the reaction mixture is treated with water or an aliphatic alcohol containing less than 6 carbon atoms, whereby the nitrites are hydrolysed to nitro-alcohols.  Products obtainable are dinitro-ethane, beta-nitroethanol and its nitrate from ethylene and 1 : 2-dinitrocyclohexane, 1-nitro-cyclohexanol-2 and its nitrate from cyclohexene.  A number of methods of separating the various products are described.  According to the Provisional Specification, the starting materials may comprise any aliphatic mono-olefines, other than those containing 3-6 carbon atoms, or cyclic mono-olefines or substituted derivatives thereof.
