Abstract: An image projection system for producing a projected image in response to electrical signals which represent the image to be projected. The projection system includes input capability to produce electrical signals in response to an image to be projected. These electrical signals are then transmitted to a light modulator which receives light from an external source. The light modulator consists of arrays of deformable mirrors which selectively deflect the light from the external source in response to the electrical signals received from the input capability. The deflected light is absorbed by opaque stops. The undeflected light travels through optics which form the projected image. A printer using this image projection system is also disclosed. The printer further includes the ability to develop the projected image in such a manner that the image is transferrable to a paper surface in a printer in such a manner that the image is reproduced upon the surface in a printer form.

Abstract: A magnetic bubble domain package in which a magnetic bubble domain chip is bonded to conductors disposed on a thin film interconnect member which is formed to allow a reduction in the volume of the drive coils of the package. The conductors of the interconnect member are bonded to a lead frame which provides signal leads for the magnetic bubble domain chip and the drive coils. The interconnect member with magnetic bubble domain chip and lead frame bonded thereto is encapsulated with a molding compound, the chip being located precisely within the mold in order to insure placement of the chip in the geometric center of the drive coils. The drive coils are prewound and slipped onto the premolded package through slots formed during the molding process to reduce the volume of the coils, and the coils terminated directly onto the signal leads of the lead frame.

Abstract: Magnetic bubble domain memory circuit in which magnetizable overlay patterns of magnetically soft material, e.g. permalloy, are provided as bubble propagation elements on a bubble-supporting magnetic layer to define major and minor bubble propagation paths. The major bubble propagation paths provide interchangeable bubble input and output sections, and the minor bubble propagation paths are in the form of closed storage loops providing a bubble storage section comprising first and second pairs of blocks. Bubble generators are provided for each of the blocks included in the first and second pairs thereof comprising the bubble storage section, along with first and second detectors and input/output tracks of bubble propagation elements associated with the respective pairs of blocks of storage loops. Swap transfer/replicate gates are disposed between the input/output tracks and each of the storage loops included in the blocks of storage loops.

Abstract: Magnetic bubble domain memory circuit in which magnetizable overlay patterns of magnetically soft material, e.g. permalloy, are provided as bubble propagation elements on a bubble-supporting magnetic layer to define major and minor bubble propagation paths. The bubble propagation elements are arranged to form major propagation paths defining a bubble input section and a bubble output section respectively. A plurality of minor propagation paths in the form of closed storage loops defining a bubble storage section are disposed between the input and output bubble sections, being arranged in even and odd blocks of minor propagation paths. Input swap transfer gates and output replicate gates are provided between the bubble storage loops and the input and output sections respectively. The input swap transfer gates and the output replicate gates are of double level construction, each type of gate including a hairpin element at the first level and a 90.degree.
