    摘要: 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.

    摘要: A first laser beam is emitted from a first laser oscillator in a pulsed manner at a high repetition frequency, and converged onto a substrate by a first intermediate optical system 2 so as to form a slit-like first beam spot. A second laser beam is emitted from a second laser beam oscillator in a pulsed manner to rise precedent to and fall subsequent to the first laser beam, and converged onto the substrate by a second intermediate optical system so as to form a second beam spot similar in configuration to the first beam spot and to contain the first beam spot. Crystallization of a semiconductor thin film on the substrate is carried out while the substrate or the first, second beam spots are moved. Thereby, the whole semiconductor thin film is formed into a crystal surface that has grown in one direction and free from ridges. Thus, the semiconductor thin film has an extremely flat surface, extremely few defects, large crystal grains and high throughput.

    摘要: Embodiments of the invention relate to manufacturing method of a magnetic head slider which flies stably even with a reduced peripheral speed resulting from a trend toward a magnetic disk having a smaller diameter. According to one embodiment, a method of manufacturing a magnetic head slider comprises forming a leading side rail surface and a trailing side rail surface, a leading stepped bearing surface and a trailing stepped bearing surface, and a negative-pressure groove surface on an air bearing surface through etching, forming a first stepped surface on the leading side rail surface through sputtering, and forming a second stepped surface by forming a carbon layer on the first stepped surface through sputtering. The first stepped surface has a first height with respect to the leading side rail surface and the second stepped surface has a second height with respect to the first stepped surface.
