    摘要： A therapeutic device may be used in providing physical therapy for a patient's knee by moving the patient's leg through a plurality of cycles of motion in each of a number of treatment sessions. The device includes a “Comfort Zone” range of motion feature which allows an operator to temporarily increase the flexion angle (or decrease the extension angle) to alleviate discomfort the patient is experiencing as the upper leg support and lower leg support pivot or attempt to pivot through a portion of the operational range of motion. The preferred embodiment of the device will automatically decrease the flexion angle (or automatically increase the extension angle) at a predetermined rate over a period of treatment time, so that the device may return to operation between the preset operational limits of the range of motion with a lower chance that the patient will experience the same pain or discomfort which necessitated the establishment of a Comfort Zone limit. In a preferred embodiment of the invention, the carriage holding the patient's leg is decelerated, at a controlled rate over a controlled distance, from the operational speed to zero, as the carriage approaches the extension or flexion limit, and the carriage is accelerated in the same fashion as the carriage moves away from the extension or flexion limit.

    摘要： Sulphonated polyketones are prepared by reacting a linear alternating copolymer of carbon monoxide and one or more olefins (polyketone) with a sulphonating agent (e.g. chlorosulphoric acid) in a solvent (e.g. dichloromethane) at a temperature in the range -20.degree. to +40.degree. C. A molar excess of sulphonating agent is preferably used. The sulphonated polyketone produced contains one or more types of unit of formula--[COC(R.sup.1).sub.2 C(R.sup.1).sub.2 ]--wherein the R.sup.1 groups are independently H, C.sub.1 to C.sub.10 alkyl or SO.sub.3 H with the proviso that at least one R.sub.1 group is SO.sub.3 H.

    摘要： A process for preparing interpolymers of an olefin(s) and carbon monoxide (polyketones) is provided. The process employs a palladium catalyst prepared by reacting together a palladium source, a bidentate amine, phosphine, arsine or stibine and a source of a borate anion. The catalyst effects fast polymerization of the olefin(s) and carbon monoxide in, e.g. methanol or ethoxyethanol solvent. By using the catalyst a lower catalyst deactivation on recycle is observed relative to previously described systems.

    摘要： A semiconductor device formed between a wordline and a bitline comprises a growth layer, an antiferromagnetic layer formed on the growth layer, a pinned layer formed on the antiferromagnetic layer, a tunnel barrier layer formed on the pinned layer, and a free layer formed on the tunnel barrier. The wordline and bitline are arranged substantially orthogonal to one another. The growth layer, in turn, comprises tantalum and has a thickness greater than about 75 Angstroms. Moreover, the pinned layer comprises one or more pinned ferromagnetic sublayers. The tunnel barrier comprises magnesium oxide. Finally, the free layer comprises two or more free ferromagnetic sublayers, each free ferromagnetic sublayer having a magnetic anisotropy axis that is oriented about 45 degrees from the wordline and bitline. The semiconductor device may comprise, for example, a magnetic tunnel junction for use in magnetoresistive random access memory (MRAM) circuitry.

    摘要： Measurement of the extinction coefficient k is employed for effective and prompt in-line monitoring and/or controlling of the metal film composition. The dependency of the extinction coefficient on the composition of a metal compound is characterized by measuring the extinction coefficients of a series of the metal compound with different compositions. A monitor metal film is then deposited on a wafer. The extinction coefficient k of the film on the wafer is measured and a film compositional parameter is extracted. The wafer processing may continue if k is in specification or the needed compositional change in the film may be extracted from the measured value of the k and the established dependence of k on the composition of the film for out-of-spec k values.
