Abstract: Storage of information is performed by interference effects in depth in an optically accessible information storage unit. The storage unit is divisible into a plurality of individual information storage areas permitting the recording of the information in the form of various light and no light conditions. Plural light scattering layers are formed in depth in the unit corresponding to the information stored in that area. Read out is performed by applying light to the unit. The scattering layers act on the applied light in accordance with the information stored to provide indications for detection of the stored information.

Abstract: The apparatus determines the wire routings in a VLSI circuit comprised of cells, wherein the cells are composed of electronic devices functioning as logic gates. Groups of cells may be interconnected to function as flip flops, shift registers and the like. A supervisory controller communicates with a number of identical multi-port processors, with one processor dedicated to each cell, for determining the wire routings between the respective cells. Each processor communicates simultaneously with its four adjacent neighbour processors to determine channel routings from one point to the next in the array of cells, wherein a channel routing includes vertical and horizontal paths. Following determination of global channel routings, exact vertical and horizontal tracks for the wire paths are assigned. The array of processors may be utilized to wire a much larger array of cells. The arrangement gives reduced design times.

Abstract: 1,142,957. Light deflectors. INTERNATIONAL BUSINESS MACHINES CORP. 2 June, 1966 [7 June, 1965], No. 24606/66. Heading H4F. A collimated beam of monochromatic preferably circularly polarized radiation 4, Fig. 1, is deflected by directing, e.g. by means of mirror M1, the beam along a path through an ionizable gas in a container, and by creating a magnetic field along the path having an intensity varying progressively across the plane perpendicular to the path by means of polepieces 12 and 14 of electromagnet 16, the gas being excited by means of a radio frequency electric field applied by means of conductive rings 6 and 8. Since the dispersion characteristic of the gas or plasma is a function of the magnetic field, variation in the strength of the magnetic field varies the refractive index of the gas and controlled angular deflection is accomplished. The ionizable gas may comprise Helium, Argon, Krypton or Xenon and is sealed under pressure in glass or quartz cylindrical container 2. The radiation beam may be emitted from a microwave, millimeter or optical maser. The polepieces of electromagnet 16 are shaped to provide a magnetic field with constant gradient between the upper and lower surfaces of container 2. It is arranged that the electrons gyrate in the ionized gas in the same sense as the beam is circularly polarized. If the incident beam is plane polarized its plane of polarization is rotated after passing through the gas. The actual deflection in the gas takes place due to the fact that each point on the wavefront travels at a different velocity. The deflection may be controlled by varying the magnetic field strength and/or the electron density. Solid bismuth which exhibits cyclotron frequency phenomena and is transparent to long wavelength radiation may be used to increase the electron densities.

Abstract: The present disclosure describes, in one embodiment, a scanner making use of a bubble plate for transfer of information. Circuits and structures are provided for populating, that is filling the bubble plate initially, feeding a document into close proximity with the plate, establishing a field bias relative to the document and plate which achieves an imaging effect of the information on the document into the bubble plate, thereafter moving the plate away from the document, feeding the document out, and shifting the information contained in the bubble plate to another device, such as a storage unit, or the like. Another embodiment utilizes drum members for the bubble and bias elements and this embodiment can be provided with a toner development adjunct. Such as adjunct could also be provided, if desired, in connection with the plate embodiment.

Abstract: A scanner transfers information in the form of magnetic characters to a soft magnetic film, and subsequently transfers the information to a storage medium, such as disc, tape, or the like. Use of amorphous and other bubble material is suggested. A bias field is coupled through the magnetic characters to the material in which bubbles are generated and transported.

Abstract: 1,026,317. Lasers. INTERNATIONAL BUSINESS MACHINES CORPORATION. April 28, 1964 [May 1, 1963], No. 17489/64. Heading H3B. [Also in Divisions G2 and G5] Information is recorded on a thermoplastic surface by using a laser beam to heat the surface and cause local deformations in the surface. In Fig. 1, the beam from a laser 16 is split by a half-silvered mirror 20 and part of the beam is focused by a lens 26 on to the tape record 10 to melt its surface and thereby erase any information previously recorded. The other part of the beam is reflected by a mirror 28 through a variable focus lens 34 and a fixed focus lens 36 on to the tape which has previously been electrically charged by a unit 30. The lens 34 is adapted to focus or defocus the beam under the control of an information source 37, and when the beam is focused the record is heated sufficiently to cause local deformation of the surface under the influence of the electrostatic charge and surface tension. The laser 16 may be pulsed or continuous wave and may use calcium fluoride doped with divalent dysprosium, calcium tungstate doped with trivalent neodymium, ruby, or a gas such as helium, neon, argon, krypton or xenon, or a semi-conductor gallium arsenide diode.
