| Number | Title | Issue Date |
| 5754465 | No physical movement component record reproduce device and flat display device A non-physical movement component recording and reproducing device produces a pair of special waves with special waveforms that form a special stationary waveform. An electrically-conducting media contains three overlaid layers, a first layer contains the... | 05/19/1998 |
| 4843468 | Scanning techniques using hierarchical set of curves Conventionally, transmission of television images is performed by Raster scanning. To avoid the problems associated with flyback, and the limiting of Raster scanning to image scanning standards it is proposed to transmit images by scanning along a locus d... | 06/27/1989 |
| 4357682 | Conductorless transfer for magnetic bubble memories A conductorless transfer is provided for a large-gap tolerant Permalloy pattern for moving magnetic bubbles. The transfer capitalizes on the symmetry of the elements for enabling a field reversal to achieve transfer.... | 11/02/1982 |
| 4316263 | Transfer and replication arrangement for magnetic bubble memory devices A magnetic bubble replication and transfer arrangement is disclosed which provides for replicating magnetic bubbles in thin planar layers of magnetic material without the need for electrical current carrying conductor elements. The arrangement includes a ... | 02/16/1982 |
| 4164028 | Current access bubble memory system A current access bubble memory system includes a method and device for propagating and switching isolated bubbles within a plurality of orthogonal propagation channels. The device includes two orthogonal arrays of parallel current conductors oriented at 4... | 08/07/1979 |
| 4151601 | Magnetic domain memory device with an improved detector A magnetic domain memory in which domains are driven along a structure of discrete elements which includes at least two domain detection elements formed by interconnected chevrons. The detection signal is based upon the magnetoresistive effect of the seri... | 04/24/1979 |
| 4059828 | Bubble lattice file structure In an improved bubble lattice file (BLF) structure, two adjacent layers of magnetic bubble domain material are utilized to provide separate media for supporting carrier bubbles or coded bubbles. The coded bubbles, in one layer, represent data stored in th... | 11/22/1977 |
| 4006276 | Magnetic bubble domain field shunt A magnetic bubble domain composite comprising an overlay of highly permeable magnetic material, such as permalloy, is provided for bubble domain material to shunt the magnetic field formed by bubble domains therein into a path that is substantially within... | 02/01/1977 |
| 4002803 | Magnetic bubble devices with controlled temperature characteristics The temperature variation of the bubble collapse field of a class of garnet magnetic bubble layer materials is selected by control of octahedral site substitution during layer growth. This permits the growth of layers, whose temperature dependence of crit... | 01/11/1977 |
| 3940751 | Mutually exclusive parallel-sided loops Parallel "crow-foot" circuit elements in different bubble paths symmetrical about an axis parallel to and between the paths propagate bubbles in opposite directions with the same set of pulsed drive fields and are used to build closed loop paths with para... | 02/24/1976 |
| 3940631 | Magnetic bubble logic gates Three magnetic bubble logic gates are disclosed in this application. One gate produces the AND and NAND logic functions, one gate produces the OR and NOR logic functions, and the third gate produces the majority function. In the gate providing the AND and... | 02/24/1976 |
