Abstract: The present invention relates to a compound flooring material. The compound flooring such as thermoplastic/wood compound flooring is produced by adhering two layers through adhesive cementing. According to an embodiment, a first sheet is a high quality wood veneer and the second sheet is a low foaming, environment friendly, UPVC board. The sheets are bonded by incorporating a high quality polyvinyl acetate polymer adhesive that contains no formaldehyde, thus providing a strong, safe, odorless product. The UPVC/wood compound flooring has a very low shrinking and swelling rate and is convenient and accurate to install.

Abstract: A slide type writing tool having a dryness prevention unit. The writing tool includes a hollow shaft having at a first end thereof a nib hole. A knock part is inserted into an insert hole formed in a second end of the shaft. A cartridge is inserted into the shaft and is integrated with the knock part. A control module is made of an elastic material, such as rubber, and includes an O-ring part coming into close contact with the nib hole, a spherical door having a spherical surface, a tubular holder secured to the cartridge, a first hinge coupling the O-ring part with the spherical door, and a second hinge integrally coupling the spherical door with the holder. First and second springs are provided in the shaft to act elastic restoring force between the control module and the cartridge.

Abstract: The present invention relates to methods of decreasing the infectivity, morbidity and rate of mortality, in treating diseases associated with a variety of pathogenic organisms, specifically diseases involving one or more pathogens that require neuraminidase as a virulence factor. In addition, the present invention uses biology based therapy to treat neuraminidase dependent infections or diseases dependent on sialic acid metabolism.

Abstract: The present invention relates to a nitride micro light emitting diode (LED) with high brightness and a method of manufacturing the same. The present invention provides a nitride micro LED with high brightness and a method of manufacturing the same, wherein a plurality of micro-sized luminous pillars 10 are formed in a substrates, a gap filling material such as SiO2, Si3N4, DBR(ZrO2/SiO2HfO2/SiO2), polyamide or the like is filled in gaps between the micro-sized luminous pillars, a top surface 11 of the luminous pillar array and the gap filling material is planarized through a CMP processing, and then a transparent electrode 6 having a large area is formed thereon, so that all the luminous pillars can be driven at the same time. In addition, the present invention provides a nitride micro LED with high brightness in which uniformity in formation of electrodes on the micro-sized luminous pillars array is enhanced by employing a flip-chip structure.

Abstract: The present invention relates to a wheelchair having a back plate and a seat plate and a manufacturing method thereof, and more particularly, to a customized wheelchair having a back plate and a seat plate formed to fit a body shape and a manufacturing method thereof. In a method of manufacturing a customized wheelchair having a back plate and a seat plate which are designed to fit a body shape, the method includes steps of: forming a preliminary molding material which is directly formed to fit a back and a hip of a user; fixing the preliminary molding material to a molding frame; filling a foaming resin in the molding frame fixed with the preliminary molding material; hardening the foaming resin filled in the molding frame; and releasing a last molding material which is foamed and hardened to have a shape of the back and the hip of the user by the preliminary molding material.
