| 20090023086 | RECORDING MEDIUM FOR ELECTROPHOTOGRAPHIC PRINTER - A recording medium for an electrophotographic printer is provided. The recording medium includes a substrate and a toner receiving layer formed on at least one surface of the substrate. The toner receiving layer includes a white pigment, an acryl based emulsion latex and polyvinyl alcohol, and an average viscosity of the polyvinyl alcohol is less than 25 cps in a 4% aqueous solution maintained at 20° C. | 01-22-2009 |
| 20090130577 | RECORDING MEDIUM FOR ELECTROPHOTOGRAPHIC APPLICATIONS - A recording medium for electrophotographic applications includes a base layer and an outermost coating layer containing a porous adsorptive material. According to the present general inventive concept, since a porous adsorptive material is contained in an outermost coating layer of the recording medium, volatile hazardous material generated from toner during a printing operation can be directly adsorbed on the recording medium to efficiently decrease or remove an occurrence of volatile hazardous material, so that a separate filter or apparatus to remove the volatile hazardous material is not needed and thus economical effects can be obtained. | 05-21-2009 |
| 20090290482 | METHOD FOR ESTIMATING TRANSMISSION DELAY AND RECEIVER USING THE SAME - There is provided a receiver for processing a ranging channel. The receiver includes a Fourier transformer for transforming a received signal into a frequency domain signal, a ranging channel extraction and ranging code elimination unit for extracting a ranging channel from the frequency domain signal, and eliminating a code of a ranging code from the ranging channel and a ranging channel processor for estimating transmission delay or transmission power from a time domain signal. By estimating transmission delay and/or transmission power in a time domain, it is possible to rapidly and accurately adjust the transmission delay and transmission power intensity in the ranging procedure. | 11-26-2009 |
| 20090318558 | SOLVENT SYSTEM OF HARDLY SOLUBLE DRUG WITH IMPROVED DISSOLUTION RATE - The present invention relates to a solvent system with improved disintegration degree and dissolution ratio of a hardly soluble drug by highly concentrating the drug through partial ionization, and by establishing optimal conditions for enhancing bioavailability of the drug, such as the co-relation between the acid drug and the accompanied components, ionization degree of a solvent system, use of an appropriate cation acceptor, water content, selection of optimal mixing ratio of the respective components and use of specific surfactants, and to a pharmaceutical preparation comprising the same. The solvent system of the invention has advantages in that it can enhance bioavailability by improving the disintegration degree and dissolution ratio of a hardly soluble drug and also provide a capsule with a sufficiently small volume to permit easy swallowing. | 12-24-2009 |
