    摘要： Within an integrated circuit, a contact plug with a height not extending above the level of the gate/wordline nitride is nonetheless provided with a relatively large contact area or landing pad, significantly larger than the source/drain region to which the contact plug is electrically connected. Methods for producing the inventive contact plug include (1) use of a nitride facet etch, either (a) during a nitride spacer formation etch or (b) during a BPSG etch; (2) using at least one of (a) an isotropic photoresist etch or partial descum to narrow BPSG spacers above the gate/wordline nitride, and (b) a nitride step etch to etch the shoulder area of the gate/wordline nitride exposed by a BPSG etch; and (3) polishing a BPSG layer down to the top of a gate/wordline nitride before any doped polysilicon plug fill, masking for BPSG etch and performing a BPSG etch, etching the photoresist layer through a partial descum, and etching the shoulder area of the gate/wordline nitride exposed thereby.

    摘要： An optical fiber cable comprises a stacked plurality of optical fiber ribbons each including a plurality of optical fibers disposed side by side in substantially the same plane and all embedded in a common covering or matrix of the ribbon. A protective outer sheath protects the cable against radial compression loads. Reinforcing members withstand traction loads applied to the cable, which further comprises filler members of a material based on reinforcing fibers and having a coefficient of expansion similar to that of the optical fibers embedded in a connecting matrix. The filler members occupy all or part of a volume delimited by the outside surface of the stacked ribbons and by the inside surface of the outer sheath so that the combination of the stack and the filler members has an external contour in cross-section that is substantially circular. The filler members protect the ribbons against radial and longitudinal loads applied to the cable and oppose contraction of the cable by more than 0.2%.

    摘要： An apparatus for the automated processing of bulk mail which incorporates a number of operating stations that serve to accomplish the various aspects of mail extraction, as well as the subsequent processing of extracted documents, and which are operatively associated with one another to serially process envelopes and extracted documents in continuous fashion and substantially independent of their characteristic features. To this end, the operating stations of the apparatus are configured to be as independent as possible of the characteristics of the envelopes and their contents so that envelopes and contents of varied characteristics can be effectively handled by the apparatus without requiring any significant adjustments. As a result, the apparatus is made capable of processing (as a single job if desired) envelopes and contents of varied characteristics, reducing the need to remove non-conforming envelopes and contents from further processing, and increasing the versatility and productivity of the apparatus.

    摘要： An invention provides an arrangement for accomplishing three objects. The first is correcting distortions caused by probe geometry in probe microscope or profilometer data. The second is calculating apparent probe data from models. The third is deducing the shape of the probe tip from a standard or reference sample. The correction of distorted images data is done by mathematically placing one or more known or hypothetical tip surfaces at one or more points of the distorted image surface to provide a reconstructed surface, which is the envelope surface formed by all such tip surfaces. The calculation of probe microscope image data from one or more mathematical models of sample surfaces is done by mathematically placing one or more known or hypothetical inverted probe tip surface at one or more points on the mathematical model surface, and taking the image surface to be the envelope formed by all such tip surfaces. The deduction of probe tip shape from an image of a known standard or reference surface at one or more points of the image surface, and taking the probe tip surface to be the envelope of all such standard or reference surfaces.

    摘要： A fiber optic cable has at least one fiber and at least one buffer tube surrounding the fiber, with the fiber being loosely held within the buffer tube. A jacket surrounds the tube where the at least one buffer tube is constructed from an extruded transparent polymer, allowing the arrangement of the fiber within the buffer tube to be visible along the entire length of the tube.
