Title: Raster shaped beam, electron beam exposure strategy using a two dimensional multipixel flash field
Inventor: RISHTON STEPHEN A
IPC: H01L21/027
Filed: 1999-09-21
Abstract: An electron beam column (or other charged particle beam column) for lithography which exposes a surface to variable shapes in a raster scan. The beam column includes an electron (or ion) source (1204) that generates a charged particle beam, a transfer lens (1206), an upper aperture (1210), an upper deflector (1212), a lower aperture (1214), a lower deflector (1216), magnetic deflection coils (1218), and a beam objective lens (1220). The beam is first shaped as a square in cross section by the upper aperture. The upper deflector changes the direction of the square shaped beam to pass through a specific portion of an opening defined in the lower aperture to shape the beam as desired. The lower aperture defines either a cross shaped opening or four L-shaped openings arranged as corners of a square. The combination of upper and lower apertures enable definition of exterior and interior corners as well as horizontal and vertical edges of a pattern, so that only one flash need be exposed in any one location on the surface. The lower deflector reverses any change in direction imposed by the upper deflector and further applies a retrograde scan to counteract a movement of the beam by the magnetic coils in a raster scan. The retrograde scan ensures that an exposure exposes an intended target area.

Title: Containment system for containing blade burst
Inventor: MODAFFERI MARIO
IPC: F01D21/04
Filed: 1999-04-19
Abstract: The present invention is addressed to a multiple layer blade burst control system for use in turbine engines. The system utilizes a first inner containment ring (81) and a second outer containment ring (82) separated by a layer of thin ductile material (83). The inner containment ring (81) and outer containment ring (82) are each mounted to an engine housing by the use of a plurality of supporting legs (84, 85, 86). The first inner containment ring and the second outer containment ring each have complementary ribs (87) and grooves (88) on their respective inner and outer surfaces, so that when broken blades or blade fragments strike the inner surface of the inner containment ring (81), this ring (81) absorbs the transfer of energy and moves towards the second containment ring (82).  The movement of the inner containment ring also deforms the thin ductile material (83) which creates an additional energy transfer. The system may also be utilized without the thin ductile layer, and a set of intermeshing protrusions and recesses. The protrusions and recesses may be either complementary or non-complementary. The system has the advantage of being light and easy to manufacture.

Patent CA-2333461-A1 (CA)
Title: Configuration description language system
Inventor: KLIORIN VICTOR
IPC: G06F17/50
Filed: 1999-07-02
Abstract: A configuration description language system in a computer environment provides a mechanism to develop sets of rules intended to govern computing systems. A  custom language is provided that the system designer uses to describe constraints and rules of target systems where a rule describes how a certain set of parameters of a computing system are determined based on an input set of desired characteristics. The desired characteristics pertain to certain tasks that the user wants to apply to such a system. The parameters (or constraints) are based upon system limitations such as memory configuration, processor speed and model number. The system designer creates rule sets using the custom language and compiler. The compiler ensures that the sets are complete and unambiguous and converts the custom language into a binary format that is compact, portable, and suitable for efficient searches, thereby minimizing execution times. A report tool is provided for the designer to verify the system's parameters and traverses all of the rule sets and creates a table of all possible combinations of options or characteristics of the target system. The resulting rule database is then read using a database manager which applies the set of rules in the rule database to input jobs or choices that the user makes. Any desired characteristics that are not available or feasible in the target system are replaced with characteristics that do make sense with respect to the target system. The output from the database manager is a corrected or constrained set of choices. This allows the rule database and the database manager to be installed in a product internally or used as a front-end to a target system, thereby providing corrected input to the target system.
