Title: Defining tooth-moving appliances computationally
Inventor: CHISHTI MUHAMMAD ZIAULLAH KHAN
IPC: A61C/
Filed: 1999-12-24
Granted: 2002-12-21
Abstract: Methods and corresponding apparatus for segmenting an orthodontic treatment path into clinically appropriate substeps for repositioning the teeth of a patient. The methods include providing a digital finite element model of the shape and material of each of a sequence of appliances to be applied to a patient; providing a digital finite element model of the teeth and related mouth tissue of the patient; computing the actual effect of the appliances on the teeth by analyzing the finite elements models computationally; and evaluating the effect against clinical constraints. The appliances can be braces, polymeric shells, or other forms of orthodontic appliance. Implementations can include comparing the actual effect of the appliances with an intended effect of the appliances; and identifying an appliance as an unsatisfactory appliance if the actual effect of the appliance is more than a threshold different from the intended effect of the appliance and modifying a model of the unsatisfactory appliance according to the results of the comparison. The model and resulting appliance can be modified by modifying the shape of the unsatisfactory appliance, by adding a dimple, by adding material to cause an overcorrection of tooth position, by adding a ridge of material to increase stiffness, by adding a rim of material along a gumline to increase stiffness, by removing material to reduce stiffness, or by redefining the shape to be a shape defined by the complement of the difference between the intended effect and the actual effect of the unsatisfactory appliance.

Inventor: METHIVIER ALAIN M
IPC: B01J20/18
Filed: 2000-02-18
Granted: 2002-08-11
Abstract: The present invention relates to agglomerated zeolitic adsorbents based on zeolite X with an Si/Al ratio such that 1.15 < Si/A1 ≤ 1.5, at least 90% of the exchangeable cationic sites of the zeolite X of which are occupied either by barium ions alone or by barium ions and potassium ions, whose Dubinin volume is greater than or equal to 0.240 cm<SP>3</SP>/g. The agglomerated zeolitic adsorbents according to the present invention are obtained by agglomerating zeolite powder with a binder, followed by the zeolitization of the binder, the exchange of the ions of the zeolite by barium ions (and optionally potassium ions) and the activation of the adsorbents thus exchanged. These adsorbents are particularly suited to the adsorption of the para-xylene present in C8 aromatic hydrocarbon fractions in the liquid phase in processes of simulated moving bed type but also to the separation of sugars, polyhydric alcohols, cresols or substituted toluene isomers.

Title: A can opener construction with better easiness in opening and enhanced sanitariness
Inventor: CHO SUNG-HO
IPC: B65D17/34
Filed: 2000-05-15
Granted: 2001-12-21
Abstract: A can lid structure, with an opening tab providing improved practicability, enhanced opening function and improved sanitariness, is disclosed. This can lid structure is preferably used with easy open cans with one-touch type opening means, or with a so-called ""stay-on tab"". In the above can lid structure, an opening tab 30, locked to a can lid using a rivet 24, is levered up by a user so as to break the seal of an opening piece 22 along a depressed seam 21 on the can lid when it is necessary to open the lid prior to emptying a can 10. In order to open the can lid, the free end portion 31 of the tab 30 is primarily raised up from the top surface 20 of the can lid while forming an appropriate gap between the tab 30 and the can lid by pressing the tab 30 downwardly by a finger. The tab 30 is, thereafter, levered up to break the seal of the opening piece 22 along the depressed seam 21. The above object is accomplished by a thumb pushing part 36, a thumb-operable resilient bulge 33, and/or a depressed linear portion 38 in the form of a groove respectively formed on predetermined positions of the tab 30. This can lid structure thus accomplishes a desired sanitariness, operational convenience and operational reliability of cans 10.

Title: Methods of forming self-aligned contact structures in semiconductor integrated circuit devices
Inventor: PARK JONG-WOO
IPC: H01L21/28
Filed: 2000-06-08
Granted: 2001-08-21
Abstract: Methods of forming integrated circuit devices (e.g., memory devices) include the use of preferred self-aligned contact hole fabrication steps. These steps improve process reliability by reducing the likelihood that contact holes will become misaligned to underlying integrated circuit device structures and thereby potentially expose the structures in an adverse manner. Typical methods include the steps of forming a plurality of interconnection patterns on a substrate and then covering a surface of the interconnection patterns and a portion of the substrate with a capping insulating layer such as silicon nitride layer. The capping insulating layer is then covered with an upper interlayer insulating layer different from the capping insulating layer. The upper interlayer insulating layer and the capping insulating layer are then dry-etched in sequence to form a first narrow contact hole that exposes the substrate, but preferably does not expose the interconnection patterns. The first contact hole is then widened in a self-aligned manner using the capping insulating layer as an etch-stop layer. This widening step is performed by wet etching sidewalls of the first contact hole using an etchant that etches the upper interlayer insulating layer faster than the capping insulating layer. In this manner, the first contact hole may be formed to initially compensate for potential misalignment errors and then a self-aligned wet etching step may be performed to widen the first contact hole into a second contact hole so that low resistance contacts (e.g., contact plugs) can be provided therein.

Abstract: A forming fabric having a paper side layer and a machine side layer comprises at least two systems of weft yarns and a single set of warp yarn triplets. In the fabric weave pattern, each member of each triplet set of warp yarns interweaves with the paper side weft yarns to occupy in sequence segments of an unbroken warp path in the paper side surface, and the members of each triplet interlace in pairs with single machine side layer weft yarns. Each segment in the unbroken warp path is separated by at least one paper side layer weft yarn. The machine side layer interlacing points can be regularly or irregularly spaced. After heat setting, the fabrics typically have a warp fill from about 105% to about 140%, an open area of at least 35% in the paper side surface, and an air permeability typically from about 3,500 to about 8,200 m<3>/m<2>/hr. Paper products made using these fabrics have enhanced printability.
