Title: Use of dynamic masks for object manufacture
Inventor: YOUNG RUPERT CHARLES DAVID
IPC: B29C67/00
Filed: 1996-07-27
Abstract: A dynamic mask (spatial light modulator) is used to produce a defined amplitude pattern in the imaging or Fourier plane of a lens system for application to object manufacture and rapid prototyping. The polarisation of an illuminating optical wavefront is amplitude or phase modulated by the spatial light modulator after transmission through, or reflection from, a polarising element. The pattern so generated is imaged or Fourier transformed to a photosensitive medium in order to create a specified level slice of the 3-D model or component under construction. Alternatively, a phase pattern is calculated and written to a phase modulating spatial light modulator. The pattern is calculated such that when optically Fourier transformed, an intensity pattern is generated in the back focal plane of the lens system. Derived from its CAD solid model, this will correspond to a given cross-section through the component or prototype under construction.

Patent GB-2325083-A (GB)
Title: A dual damascene process
Inventor: YEW TRI-RUNG
IPC: H01L21/28
Filed: 1997-05-09
Abstract: A dual damascene process forms a two level metal interconnect structure by first providing a interlayer oxide 52 over a device structure 50 and covering the interlevel oxide layer with an etch stop layer 54. The etch stop layer is patterned to form tapered openings 72 corresponding to the pattern of the interconnects that are to be formed in the first level of the two level interconnect structure. After the etch stop layer is patterned, an intermetal oxide layer 56 is provided over the etch stop layer. Because the etch stop layer is relatively thin, the topography formed on the surface of the intermetal oxide layer is relatively small. A photoresist mask is then provided over the intermetal oxide layer with openings in the mask exposing portions of the intermetal oxide layer in the pattern of the wiring lines to be provided in the second level of the interconnect structure. The intermetal oxide layer is etched and the etching process continues to form openings in the interlayer oxide where the interlayer oxide is exposed by the openings in the etch stop layer. Thus, in a single etching step, the openings for both the second level wiring lines and the first level interconnects are defined. Metal is then deposited over the structure and excess metal is removed by chemical mechanical polishing to define the two level interconnect structure.

Title: Isocyanate-based rigid foam and process for making isocyanate-based rigid foam also stable polyester polyol compositions.
Inventor: WILSON JOE C
IPC: C08G18/28
Filed: 1999-02-09
Abstract: A process for producing a rigid isocyanate-based foam comprises the steps of reacting an organic and/or modified organic polyisocyanate with a polyol composition and, optionally, with a relatively low molecular weight chain extender or crosslinker in the presence of a catalyst. Auxiliaries and/or additives may also be included in the reaction mixture. The polyol composition comprises a phthalic anhydride-initiated polyester polyol, a blowing agent comprising a C 4 -C 6  hydrocarbon, and a fatty acid or fatty alcohol ethoxylate compatibilizing agent. The blowing agent is soluble in the polyol composition, thereby reducing the risks associated with the use of such blowing agents in the manufacture of rigid polymer foam articles and enabling the production of rigid foam having good dimensional stability and improved insulation properties. The stable polyester polyol composition and the isocyanate-based rigid foam are also claimed as such.

Title: Improving memory performance by using an overlay memory
Inventor: NELSON MARVIN D
IPC: G06F12/08
Filed: 1999-02-26
Abstract: It has been determined that considerable data which is written to stacks is of the type that does not require long term retention (i.e., it is only required to be valid for the duration of a procedure or function which created it). Accordingly, when a stack is employed to handle such data (and other similar data), invalidation and writes to main memory that ordinarily accompany accesses of such data (when the stack is held in a cache memory) can be avoided. The invention therefore improves memory performance by providing an overlay memory, 23, to which is assigned a set of main memory addresses that are utilized for stack operations. When data is either read or written from/to the overlay memory, there is no further communication "downstream" to either a cache memory 30 or main memory 16. In other words, the overlay memory is used for short term storage and accesses to the overlay memory are invisible to other memory elements of the system. There is thus no need to invalidate any data nor to write such data to main memory. As a result, substantially improved memory operations result.
