Abstract: Methods for fabricating a sintered element from unsinterable material, utilizing the property that it will form a eutectic composition or alloy with a suitable alloying agent at a temperature which is below the plastic deformation temperature of the material. Discrete particles of the material to be sintered are coated with a thin coating of the alloying agent and are packed into position to be sintered. Then, the coated grains or wire pieces are heated so that at least the coating and the regions of the grains just below the coating are slowly raised in temperature. Diffusion regions of alloying agent into the grains of the sinterable material will occur. Further heating continues so at least the diffusion regions increase in temperature to slightly above the eutectic melting point. Localized melting of the diffusion regions occurs where the eutectic concentration is reached, and adjacent grains begin to share the localized melting regions and become mutually wet. The alloying agent continues to diffuse, and drops in concentration, so that it freezes out of the localized melting regions. The melting point of the melting regions tends to rise, and the wetted melted regions freeze to form a sintered and solid element.

Granted: 2001-03-13
Abstract: A software partitioning tool is disclosed. Based on a visual display of an application that shows program objects and the connections or interactions between the objects, an internal representation of the application is defined. As the user interacts with the visual display of the application, creating new partitions and relocating program objects in the new partitions, the internal representation of the display is constantly updated. Once a connection between program objects crossespartition boundaries, it is redefined in the internal representation as a distributed interaction (a connection), and representative server and client stubs are defined. At a number of points, the user also has the opportunity to set middleware protocols. Once the user commits to a distribution design, a code generator in the tool generates the actual server and client stubs for all distributed connections based on the definitions in the internal representation of the application.
