Filed: 1997-12-31
Abstract: A   workflow  mechanism   for   a   stateless   or connectionless  environment  such  as  the  Internet  or  an Intranet.   The workflow mechanism comprises an inference engine and a justification based truth management system.  The inference engine and the justification based truth management system are packaged in the workflow item together with the data and business rules components, and downloaded with the workflow item to a client.  The inference engine informs the truth maintenance system about the justifications relevant to workflow items.  When the time comes to determine state of a workflow  item,  the  inference  engine  queries  the  truth maintenance system which provides the state of the workflow item based on the various antecedents which are currently believed  in  for  the  workflow  item.    Because  the  truth maintenance  system carries  the justifications,  continuous network connection is not required.

Title: Dual-walled exhaust tube for vacuum pump
Inventor: VERRIER KEVIN R
IPC: H01L21/265
Filed: 1998-05-01
Abstract: A dual walled exhaust assembly (28) is provided for an ion implantation system for connecting system components residing at differing voltage potentials. The assembly comprises a disposable corrugated inner tube (84) connected between inner mounting portions of a first end mount and a second end mount and a permanent outer tube (82) connected between outer mounting portions of the first and second end mounts. The inner and outer tubes (84 82) are constructed from polytetrafluoroethylene (PTFE) or some similar dielectric material with appropriate non-flammable properties. The inner corrugated surface of the tube (84) has a plurality of surfaces which are pitched downwardly toward an axis (87) of the inner tube to prevent contaminant accumulation. The corrugated surface also reduces the risk of arcing between the system components residing at differing voltage levels by effectively increasing the length of the ground path that a leakage current would need to traverse across the length of the tube. The outer tube provides a containment mechanism for containing the toxic effluent if the thinner inner wall should puncture perhaps due to electrical discharge which might still occur as aresult of contaminant build-up on the inner surface of the inner tube.
