Abstract: Fibers that exhibit good elasticity or extensibility and tenacity, and low modulus are prepared from propylene-based copolymers. The propylene-based copolymers comprise at least about 50 weight percent (wt %) of units derived from propylene and at least about 8 wt % of units derived from one or more comonomers other than propylene, e.g., ethylene. Particularly preferred propylene copolymers are characterized as having 13C NMR peaks corresponding to a regio-error at about 14.6 and about 15.7 ppm, the peaks of about equal intensity. In one aspect of the invention, fibers are subjected to stress-induced crystallization by subjecting the fiber to tensile elongation during draw.

Abstract: A method is disclosed for accurately predicting the wet etch end points as a function of the temperature and concentration of the etching solution, as well as of the thickness of the film to be etched. This is accomplished by fitting an etch rate equation to the process of etching a film in terms of two constant parameters that are determined by one set of experiments performed on a given wet etch bench. Thereafter, the constants are used with the rate equation to calculate precisely the etch rate of a film, and then the etch rate is divided into a target film loss or a target film thickness to obtain etching time, or time to etch, which takes into account the variations in temperature and concentration, for example, of the acid in the solution. The resulting film either looses the specified amount of material, or acquires the specified thickness without incurring any damage, which is especially suited for sub-micron semiconductor technology where precise etching is required.

Abstract: Dies which facilitate the threading of a strand are disclosed. Each die embodiment includes portions that move relative to each other to allow access to the area between the portions. One embodiment of a die embodying the principles of the invention includes an upper portion and a lower portion. Each die portion includes components corresponding to substantially half of a wirecoating die. Accordingly, when the die portions are adjacent each other, they form a complete wirecoating die. In the preferred embodiment, the upper portion is moveable relative to the lower portion, which is fixed. Each portion is coupled to a support by a conduit through which resin can be supplied to the particular die portion. The upper portion is pivotally mounted to the support for movement between an upper position in which the die is open and a lower position in which the die is closed. This die is used in an in-line wirecoating process in which a strand is wirecoated downstream from a bushing during a fiber forming process.

Abstract: A system and method for detecting a molecular event in a test sample using a resonant test structure is presented. The method includes providing a resonant test structure having a resonant response associated therewith. Next, a first resonant response of the resonant test structure is obtained when the resonant test structure is electromagnetically coupled to a reference sample, the reference sample having a known composition. A second resonant response is also obtained when the resonant test structure is electromagnetically coupled to the test sample, the test sample having an unknown composition. Subsequently, one or more first electrical parameters, such as the q-factor of the resonator, are derived from the first resonant response. One or more second electrical parameters are similarly derived from the second resonant response. The similarity or difference between the first and second electrical parameters are analyzed to determine the presence or absence of the molecular event in the test sample.

One or more permittivity coefficients is defined for the detector. A first output parameter is obtained from the detector when the detector is electromagnetically coupled to a reference sample. A second output parameter is obtained from the detector when the detector is electromagnetically coupled to the test sample. The difference between the first and second output parameters is applied to the one or more permittivity coefficients to compute the relative difference in permittivity between the test sample and reference sample.
