  • Publication number: 20070277882
    Abstract: Provided is a float type drain trap improved in terms of opening and closing of a valve seat. In the prior art, the valve seat is opened and closed mainly by a self-weight of a float and buoyancy of a float main body, so the valve seat is often left in a half-open state, with opening and closing of the valve seat being rather equivocal. Afloat is accommodated in a case, and drain water allowed to flow into the case is enabled to be discharged by buoyancy acting on the float. By providing a magnet between the case and the float, an attraction force is generated, and an outlet port formed in the case is closed or opened based on the relationship between the buoyancy, the attraction force, and the positions where these forces are generated, thereby making it possible to retain and discharge the drain water.

  • Publication number: 20070196336
    Abstract: A method is provided for rapidly and reliably constructing recombinant herpes simplex virus (HSV) capable of expressing a target protein in cancer cells. The method for constructing recombinant HSV as claimed in the present invention comprises a first step of inserting into a herpes simplex virus (HSV) genome, a BAC plasmid, which has a loxP site and an FRT site and into which has been inserted at least one type of marker gene expression cassette between the loxP site and the FRP site, a second step of constructing a shuttle vector into which has been respectively inserted at least one type of expression cassette of a gene encoding a target protein, at least one type of marker gene, a loxP site and an FRP site, and inserting the shuttle vector into the loxP site of the HSV genome using Cre recombinase, and a third step of co-infecting a host with the HSV genome and a vector capable of expressing Flp recombinase, and excising the region between the FRT sites in the genome to produce a target recombinant HSV.

  • Publication number: 20040166042
    Abstract: A compressor generates compressed air. Iron powder is provided in a deoxidizing chamber. The compressed air is supplied to the deoxidizing chamber such that the compressed air reacts with the iron powder to form iron oxide, so that oxygen contained in the compressed air is reduced to obtain remained nitrogen gas.
