Granted: 2000-01-21
Abstract: To provide a tension control system in a false twist texturing machine for producing a doubled yarn wherein the target tension values or allowable ranges of filament yarns y1 and y2 prior to doubling can be individually set for each filament yarn and wherein based on the results of the detection of the tension of the filament yarn prior to doubling, each false twister T for the corresponding filament yarn is individually and independently controlled in such a way that the tension of each filament yarn has the set target tension value or falls within the set allowable tension range. A target tension value and an allowable tension range can be individually set for each filament yarn prior to doubling so as to accommodate the yarn's material, thickness, and structure, and the false twister can be individually and independently controlled based on the results of the detection of the tension of each filament yarn prior to doubling.

Title: Assembly and method for rapid measurement of cell layers
Inventor: WARDLAE STEPHEN C
IPC: G01N15/05
Filed: 1998-03-10
Granted: 2000-08-01
Abstract: A sample of anticoagulated whole blood contained in a transparent tube is centrifuged so as to gravimetrically separate the various blood cell and other components by specific gravity. The tube may contain an insert or float which serves to elongate certain of the separated component layers. The various component layers may be periodically measured during the centrifugation step by a linear image dissector which can detect differential fluorescence in the several component layers. The blood component layers are caused to fluoresce by flashes of light which are directed toward the blood sample tube as the latter is being centrifuged. The gravimetric separation and quantification of blood sample constituent layers are thus both performed while the sample remains in the centrifuge. The ultimate degree of constituent layer compaction may be measured during centrifugation directly, or it can be extrapolated from a plurality of sequential preliminary measurements which are made during centrifugation prior to ultimate compaction being achieved.

Title: A method for preventing electroplating of copper on an exposed surface at the edge exclusion of a semiconductor wafer
Inventor: JAIN AJAY
IPC: C25D7/12
Filed: 1998-03-26
Granted: 2000-06-01
Abstract: A method for forming a copper interconnect (54) begins by depositing a barrier layer (48). An intermediate layer (50) is formed over the barrier layer (48) by exposing the barrier layer (48) to a plasma silane environment. The layer (50) is conductive when deposited so that contact resistance is not affected. The layer (50) is insitu covered with a copper seed layer (52). The layer (50) is not formed in an edge exclusion region (20) thereby exposing a portion (50a) of the layer (50). This portion (50a) will natively oxidize in a room ambient to form a copper electroplating prevention barrier whereby copper will not electroplate in the region (20). Therefore, the region (50a) prevents barrier-to-copper interfaces to avoid delamination of the copper while preserving the edge exclusion region desired for copper electroplating.
