Abstract: ABSTRACT     A virtual processor mechanism and specific techniques and instructions for utilizing such virtual processor mechanism within an SIMD computer having numerous processors, and each physical processor having dedicated memory associated therewith.  Each physical processor is used to simulate multiple "virtual" processors, with each physical processor simulating the same number of virtual processors.  The memory of each physical processor is divided into n regions of equal size, each such region being allocated to one virtual processor, where n is the number of virtual processors simulated by each physical processor. Whenever an instruction is processed, each physical processor is time-sliced among the virtual memory regions, performing the operation first as one virtual processor, then another, until the operation has been performed for all virtual processors. Physical processors are switched among the virtual processors in a completely regular, predictable, deterministic fashion.  The virtual processor mechanism switches among virtual processors within instructions, so that at the completion of each instruction, it has been executed on behalf of all virtual processors,  a number of instructions are shown for execution using these virtual processor techniques.

Filed: 1988-05-05
Granted: 1991-06-04
Abstract: Abstract:    A method for fabricating a multilayer interconnection system that is fully planar with completely sealed and corrosion resistant conductors separated by dielectric material.  The method involves forming a dielectric sub-layer overlying a base layer, the sub-layer being non-soluble after it is cured.          A sacrificial sub-layer is then formed over   the dielectric sub-layer, the sacrificial sub-layer being insoluble after it is cured.  A portion of the sacrificial sub-layer is removed to expose a portion of the dielectric sub-layer.  The exposed portion of the dielectric sub-layer and a selected portion surrounding the exposed portion is removed to expose a portion of the base layer with an exposed portion of the sacrificial sub-layer overhanging the exposed portion of the base layer.  A first conductive adhesive sub-layer is deposited overlying the dielectric and sacrificial sub-layers and the exposed area of the base layer without overlaying the exposed overhanging portion facing the base layer of the sacrificial sub-layer.  A conductive seeding sub-layer is deposited overlaying the first conductive adhesive sub-layer.  The sacrificial sub-layer and the first conductive adhesive sub-layer and the conductive seeding sub-layer in contact with the sacrificial sub-layer are removed, a conductor sub-layer is formed by electrolessly plating a conductor sub-layer onto the seeding sub-layer, and then a second conductive adhesive sub-layer is formed by electrolessly plating the second adhesive sub-layer onto the conductor sub-layer to form a surface which is planar with the dielectric sub-layer.          The resulting structures are useful, for example, as VLSI and ULSI devices.

Title: Thermally self-adjusting mount for proximity sensor
Inventor: TWERDOCHLIB MICHAEL
IPC: G01B5/00
Filed: 1988-08-09
Granted: 1991-09-03
Abstract: ABSTRACT OF THE DISCLOSURE           A thermally self-adjusting mount for a proximity sensor for detecting movement of a turbine blade tip within a turbine housing includes an elongated chamber in an interior wall of the turbine housing adjacent the path of travel of the turbine blade tip.  The chamber is configured to receive a blade tip sensor therein and accommodate relative movement of the senor toward and away from the path of travel of the blade tip.  A thermally expansive element is operable coupled with the sensor for moving the latter in the chamber toward the path of travel of the blade tip upon heating of the sensor. A spring is provided for maintaining the sensor in contact with the thermally expansive element during both expansion and contraction of the latter.  The thermally expansive member is capable, upon being heated to any given temperature, of causing movement of the sensor in the chamber and relatively toward the path of travel of the blade tip a distance which is substantially the same as the linear movement of the wall away from the path of travel due to having been heated to the same temperature.  Thus, the spatial relationship between the sensor and the path of travel of the blade tip remains the same at different temperatures.
