    摘要： A vector production system is provided. The system comprises recombinant cells designed to encode at least a first recombinase under the control of an inducible promoter and the cells include an expression vector encoding a nucleic acid of interest within the regulatory elements of the expression vector which are flanked on either side by a target sequence for at least the first recombinase.

    摘要： A sintered metal bearing is formed through sintering of a compact obtained through compression molding of raw-material powder. The sintered metal bearing includes chamfered portions that are respectively formed at least along outer rims of both end surfaces of the sintered metal bearing, and a dynamic pressure generating portion formed on an inner peripheral surface of the sintered metal bearing by sizing. An axial dimension of each of the chamfered portions is set smaller than a radial dimension of the each of the chamfered portions, and a difference in axial dimension between the chamfered portions on one end side and another end side in an axial direction of the sintered metal bearing is set larger than a difference in radial dimension between the chamfered portions on the one end side and the another end side in the axial direction.

    摘要： A fluid dynamic bearing (FDB) includes a groove configuration that includes a pressure-generating groove pattern, and additionally includes a circumferential groove adjacent to the pressure-generating groove pattern and a pumping groove pattern adjacent to the circumferential groove. The circumferential groove may be deeper than the associated pumping and pressure-generating groove patterns and may extend for 360 degrees, and the pumping groove may be positioned at or near the entry to the bearing journal area to help maintain fluid flow direction and minimum pressure. Such an FDB groove configuration is likely to provide improved damping characteristics while maintaining relative stiffness, thereby improving vibration response characteristics.
