Title: Nucleation media
IPC: G03C5/58
Filed: 1970-09-04
Abstract: 1314238 Photo-sensitive materials HUGHES AIRCRAFT CO 4 Sept 1970 [4 Sept 1969] 42470/70 Heading G2C [Also in Division H1] A photo-sensitive medium comprises a substrate having thereon a coating the coating comprising an electron and/or photon-sensitive material selected from TiO 2 , ZnO 2  and MgO, an organic salt of Ag, Pd or Cu and a binder. The organic salt is preferably a derivative of p-toluene sulphonic acid, the binder is copoly butadienestyrene and the substrate aluminized paper or polyethylene terephthalate. Copper lactate, acetylacetonate or a halide may be added as a nucleation inducing compound. In an embodiment, Fig.2, the medium 10 is exposed to a scanned electron beam, a laser or an optical imaging system 24, thereby forming a latent image on the medium. The image is developed in chamber 28 by vapour depositing 32 a layer of Zn, Mg or Cd on the medium. Since the metal deposited on the medium is higher in the electromotive series than the metal of the organic salt, exchange takes place reducing the salt to the metal or oxide and thereby giving a stable image. The image may be read optically or electronically Fig. 3 (not shown). The exposed and developed medium 10 is scanned by an electron beam 42 and the photons emitted by electron bombardment are detected by photomultiplier 46 to give an electronic output of the image.

Abstract: 905,709. Data storage matrices. STANDARD TELEPHONES & CABLES Ltd. Dec. 20, 1960, No. 43689/60. Class 106 (1). [Also in Groups XXXVI and XXXIX] A superconducting switching element is switched to its resistive condition by pulses applied to three or more drive conductors associated with the element. As shown in Fig. 1 the superconductor consists of a bridge across a hole 2 in a thin superconducting film 3. This film is supported on an insulating layer 5 which separates it from a sensing conductor 4 on a base 6. Spaced from the superconductor by successive layers of insulation are " drive " conductors 7x, 7y, 7z. Fig. 3 shows the application of the invention to a three dimensional memory array which consists of three layers A, B, C, each containing six superconducting memory elements A1-A6, B1-B6 and C1-C6. At each level two " x " drive conductors e.g. 1xa, 2xa are associated each with three elements in a row while each of three " y " conductors e.g. 1ya, 2ya and 3ya are associated with a column of y elements i.e. two elements. The z conductors such as 1z 2z are associated with a conductor in each layer. Thus row, column and layer selection may be achieved by pulses to the appropriate x, y and z terminals.
