  • Publication number: 20110050493
    Abstract: Provided is a position information providing system which can reduce a time required for acquiring position information. An indoor transmitter is adapted to provide position information by using a second positioning signal compatible with a first positioning signal which is a spread spectrum signal from each of a plurality of satellites. The indoor transmitter includes an EEPROM which stores therein position data for identifying an installation location thereof, an FPGA operable to generate a second positioning signal including the position data as a spread spectrum signal, and a transmitting section operable to transmit the spread spectrum signal. The second positioning signal is generated to repeat the same content in a cycle shorter than that of the first positioning signal.

  • Patent number: 7829306
    Abstract: A gene encoding a production amount-potentiating factor is introduced into an animal cell to transform the cell. Alternatively, a protein production gene and the gene encoding the production amount-potentiating factor are introduced into the animal cell to transform the cell. Herein, as the production amount potentiating factor, there is used a factor having caspase activity inhibiting activity and/or protein biosynthesis activity potentiating action, for example, baculovirus P35. Further, the animal cell is cultured by a culturing method under a condition that apoptosis is not induced, so that a protein is mass-produced.

  • Publication number: 20090143569
    Abstract: The present invention is a bacteriolytic agent containing a cationic surfactant (A) of which a counteranion is an acid having a pKa (25° C.) of 0 to 10. As the counterion, a carboxylate anion is preferable. As the cationic surfactant (A), a quaternary ammonium salt-type surfactant is preferable. Examples of the useful substance include a protein, an amino acid, a nucleic acid, an antibiotic, sugars or vitamins. The bacteriolytic agent of the present invention is excellent in a bacteriolytic power in a step of extracting a useful substance from a microorganism (useful substance producing bacterium etc.). In addition, denaturation of the useful substance during the step is small.

  • Publication number: 20080254527
    Abstract: This invention is intended to isolate and identify a vWF-specific cleaving protease. The vWF-specific cleaving protease cleaves a bond between residues Tyr 842 and Met 843 of vWF and comprises a polypeptide chain having Leu-Leu-Val-Ala-Val (SEQ ID NO: 1) as a partial sequence, and more preferably comprises a polypeptide chain having the partial N-terminal amino acid sequence of a mature protein, Ala-Ala-Gly-Gly-Ile-Leu-His-Leu-Glu-Leu-Leu-Val-Ala-Val (SEQ ID NO: 2), and having a molecular weight of 105 to 160 kDa in SDS-PAGE under reducing or non-reducing conditions. Isolation and identification of this vWF-specific cleaving protease have led to the possibility of replacement therapy for patients having diseases resulting from a deficiency of the protease, such as thrombotic thrombocytopenic purpura.
