  • Publication number: 20070218120
    Abstract: Disclosed is a pH-sensitive block copolymer obtained by copolymerization of: (a) a polyethylene glycol compound (A); and (b) at least one poly(amino acid) compound selected from the group consisting of a poly(?-amino ester) and poly(amido amine) or a copolymer thereof (B). A method for preparing the same block copolymer, and a polymer micelle type drug composition comprising the pH-sensitive block copolymer and a physiologically active substance that can be encapsulated with the block copolymer are also disclosed. The pH-sensitive block copolymer is obtained by polymerization of a hydrophilic polyethylene glycol compound with a pH-sensitive biodegradable poly(amino acid) compound. Therefore, the pH-sensitive block copolymer can form a micelle structure due to its amphiphilicity and ionization characteristics depending on pH variations, and thus can be used as drug carrier for target-directed drug delivery depending on pH variations in the body.

  • Publication number: 20070158602
    Abstract: A valve disc for a faucet or a flusher includes a main body and a valve disc. The main body is provided with a water entering passage, a water exiting passage and an electromagnetic valve. The valve disc is fixed inside the main body to separate the main body into an upper water chamber and a lower water chamber.

  • Patent number: 7201359
    Abstract: A manual pressing device for a flusher includes a stop ring, a pressing rod unit, a spring, and a nut. The manual-pressing device is located in a lateral hole of the body of a flusher, normally stopping water in the flusher or pressed to connect a lengthwise hole in the body with a water-exhausting passageway for flushing water. The nut screws with the body to keep the stop ring, the pressing rod unit and the spring stably combined in the lateral hole. When the pressing member of the pressing rod unit fitted with an outer end of the pressing rod is pressed inward, the annular leak recess of the pressing rod unit may communicate with the water exhausting passageway to let water flow therethrough so as to flush water, and releasing the pressing member pressed makes the pressing rod return to its original position to block the water exhausting passageway.
