摘要:
This invention relates to power control arrangements of digital subscriber lines. The invention controls parallel subscriber lines simultaneously in an organized way, based on the measurements of crosstalk conditions of the sub-scriber lines. Different crosstalk conditions are measured. The organized way to control the transmission power levels ensures that the crosstalk does not increase to an unacceptable level in each of the subscriber lines.

The present invention relates to novel processes for the manufacture of cores of a specific polymer and a biologically active substance, and of such cores carrying a shell, i.e. microcapsules, to the cores and microcapsules thus produced, and to a pharmaceutical composition comprising such microcapsules.
摘要:
A process for producing microparticles containing biologically active substance, in which process an aqueous solution of the said substance is prepared, this solution is mixed with an aqueous solution of PEG such that the substance is concentrated and/or solidified, the substance is optionally washed, the substance is mixed with an organic polymer solution, the composition obtained is mixed, after the admixture of said polymer solution, with an aqueous polymer solution, thereby forming an emulsion of droplets of first mentioned polymer as the internal phase, said droplets are solidified into microparticles, the microparticles are dried and a release-controlling shell is optionally applied to these.
摘要:
A method and a support arrangement to steer a roller vehicle by a roller mat, which vehicle has an essentially rigid body part supporting the frame and the power engine with transmission means thereof to transmit power to a curved form turnable roller mat, whereby one side of the roller mat is shortened and the other side thereof is correspondingly lengthened. According to the invention, when the roller mat is being turned to a curved form the vehicle is tilted and its center of gravity is transferred to the side of the tilt in regard to the longitudinal axis of the vehicle. The support arrangement extends essentially the whole length of the body part, is suspended to the body part and comprises a separate, twistable, i.e. bendable or foldable, auxiliary body part supported to the support arrangement at two points on the center line of the vehicle, to which body the roller wheel assembly of the roller mat has been suspended nontransferably in regard to the auxiliary body, and which body is provided with means connected to the steering devices of the vehicle to twist the auxiliary body and thus to steer the vehicle.

Production of purified, parenterally administrable starch by washing starch containing more than 85% amylopectin in order to remove surface-localized proteins, lipids and endotoxins, subjecting the starch to a molecular weight reduction by acid hydrolysis, and optionally removing residual water-soluble proteins. Purified starch and microparticles based on such starch.
摘要:
Process for producing parenterally administrable cores. The cores are intermediates suitable for manufacturing sustained release preparations. Microcapsules incorporating a core and a shell and pharmaceutical compositions incorporating such cores and microcapsules are also provided.

Production of purified, parenterally administrable starch by washing starch containing more than 85% amylopectin in order to remove surface-localized proteins, lipids and endotoxins, dissolving the starch in aqueous medium, molecular weight reduction by shearing, and optionally removal of residual water-soluble proteins, preferably by anion exchange chromatography.Purified starch and microparticles based on such starch.
摘要:
The invention relates to a method for estimating a channel in a receiver of a cellular radio system, and a receiver receiving a signal which contains transmission of one or more users and comprising means (20) for filtering the received signal with a filter matched with the waveform of the signal, and means (20) for estimating the delays and amplitudes of the strongest received signal components from the filtered signal. In order to estimate a channel with a high accuracy, the receiver according to the invention comprises means (23) for estimating and extracting always the next strongest signal component from the signal, until all components have been estimated, and means (24, 25) for extracting from the received signal the signals interfering the most with the strongest signal component of each user, and means (24, 25) for estimating again the strongest signal component, and means (24, 25) for estimating and extracting from the signal always the next strongest signal component, until all components have been estimated.
