    • A flow proportioning assembly for dividing a portion of a fluid flow such as gas for presentation to a sensor includes a holder member having a central opening and forming an exterior peripheral passageway when inserted within a conduit of a flow meter housing. A resistor member can be adjustably mounted in the central opening downstream of a holder member aperture to encourage a laminar flow pattern and a large entrance port and a large exit port can communicate with a passageway that is operatively connected with a sensor. The exit port is downstream of the resistor member. Flexible fastener members can engage the resistor member and the holder member for ease of mounting. The resistor member can also comprise a helical arrangement of small fluid passageways to encourage laminar flow.
    • 用于将诸如用于呈现的气体的流体流的一部分分割成传感器的流量比例组合件包括具有中心开口的保持器构件,并且当插入到流量计壳体的管道内时形成外部周边通道。 电阻器构件可以可调节地安装在保持器构件孔的下游的中央开口中,以促进层流图案,并且大的入口和大的出口可与与传感器可操作地连接的通道连通。 出口在电阻构件的下游。 柔性紧固件可以与电阻件和保持件接合,以方便安装。 电阻器构件还可以包括小的流体通道的螺旋排列以促进层流。

    • Embodiments of the invention provide solutions to a problem, in which a reduced peripheral speed resulting from a trend toward a magnetic disk having a smaller diameter makes it more and more difficult to achieve a lifting force that allows a magnetic head slider to fly stably. According to one embodiment, in a magnetic head slider comprising a leading edge, a trailing edge, and an air bearing surface, the air bearing surface includes a plurality of leading side rail surfaces, a trailing side rail surface disposed in the same plane as the leading side rail surfaces and having a magnetic head mounted thereon, a stepped bearing surface having a predetermined depth δ1 from the leading side rail surface, and a negative-pressure groove surface having a depth δ2 from the leading side rail surface, the depth δ2 being even deeper than the stepped bearing surface. The leading side rail surfaces include first stepped surfaces having a predetermined height h1 and second stepped surfaces having a predetermined height h2 from the first stepped surfaces, the first stepped surfaces and the second stepped surfaces having continuity in a longitudinal direction of the magnetic head slider.
