摘要： This invention relates to a scavenging shroud mechanism for improving scavenging of a 2-stroke engine, and more particularly to a scavenging shroud mechanism for improving scavenging of a 2-stroke engine which is constructed such that a scavenging shroud mechanism is provided to a scavenging valve whereby compressed air sucked into an interior of a combustion chamber makes a tumble phenomenon along with cylinder wall surface and thereby pushes out already burned burnt gas and simultaneously is capable of efficiently feeding new air so that efficient reverse loop scavenging system is made. The scavenging shroud mechanism has a baffle 2, shroud guide notch 3 and a shroud neck 4, and a fixed supporting pin 6 and a supporting guide 5 provided on the inner side of the intake manifold 9. A shroud guide notch 3 is provided in the baffle 2 so as to permit the scavenging shroud mechanism 1 to up and down-ward movement but not right and left rotational movement.

摘要： Disclosed is a counterflow type filter trap system for filtering particulate matters from engine exhaust gases. A controller for receiving and sending information signals, is included. A metal fiber filter for capturing particulate matters included in the engine exhaust gases is provided. A back pressure sensor for sensing pressure difference between the inlet and the outlet of the metal fiber filter, is formed. A compressed air supplying portion is formed for injecting a compressed air in the opposite direction to the flow of the exhaust gases to separate the captured particulate matters from the metal fiber filter. A particulate matters collecting box for collecting the separated particulate matters and a guiding valve for guiding the separated particulate matters are provided. The life of the filter is lengthened and the apparatus has a simple structure. The filtering efficiency of the exhausted fumes is very high.

摘要： A method for the preparation of water-soluble chitosan with high purity and biological activity includes steps of: reacting chitosan oligo sugar acid salt, covalently bonded to an organic or inorganic acid, with trialkylamine in phosphate buffered saline followed by addition of an organic solvent to remove acid salt at C-2 position; adding the thus obtained reaction mixture to an inorganic acid to remove trialkylamine salt at C-6 position; and passing the thus obtained free amine chitosan through an activated carbon/ion exchange resin. The free amine chitosan is water-soluble and has a high bioavailability for application to the medicine and food industries.

摘要： The present invention relates to a water soluble chitosan nanoparticle (WSC-NP) for delivering an anticancer agent and a preparing method thereof, more precisely, a water soluble chitosan nanoparticle for delivering an anticancer agent which has function of targeting on a wanted area by introducing a functional group in the location of highly reactive amine group and becomes an excellent gene carrier with the use of water soluble chitosan since the water soluble chitosan itself can combined with DNA having a negative electric charge(−) owing to the very strong positive electric charge(+) of its amine group, and a preparing method thereof. Therefore, a water-soluble chitosan nanoparticle for delivering an anticancer agent of the present invention can effectively envelope paclitaxel by introducing hydrophilic and hydrophobic groups in the position of highly reactive amine group of the water-soluble chitosan. A water soluble chitosan nanopaclitaxel prepared as the above has an excellent re-dispersion force, after freeze-drying, in distilled water and has an outstanding anticancer effect with its accumulation in tumor cells greater than that of the other anticancer agent carriers.
