    摘要: An edge emitting semiconductor laser comprising an active, radiation-generating zone (1), and an common waveguide (8), which is suitable for guiding the radiation generated in the active zone (1) within the semiconductor laser. The common waveguide (8) comprises a first n-doped layer (4) and a second n-doped layer (5), which is arranged between the first n-doped layer (4) and the active zone (1), wherein the refractive index n2 of the second n-doped layer (5) is greater than the refractive index n1 of the first n-doped layer (4) by a value dn.

    摘要: Accurate measurement of hematocrit during blood recovery or plasma sequestration processes by means of algorithms to account for the presence of air or other non-blood substances in salvaged or separated blood is described. A method of automatic start-up of the hematocrit measurement circuit and a method of determining the minimum volume of blood required to obtain an accurate measurement of the hematocrit also is described.

    摘要: A fuel injection valve has downstream a valve seat (23), an injector plate (23), which is characterized by having a plurality of swirl-producing elements on the intake side, followed by at least one uninterrupted annular gap in the downstream direction. The swirl-producing elements are arranged in a turbine vane-shaped form by each individual element running mostly radially and being tilted in the peripheral direction and the elements being arranged behind one another in a circular shape. The annular gap (45) represents the spray geometry. With this arrangement the fuel can be finely atomized without additional power consumption. The breakup into minute droplets results in further reduction of the exhaust emissions of an internal combustion engine and in lower if fuel consumption. The fuel injection valve is especially well-suited for use in injection systems of mixture-compression externally ignited internal combustion engines.

    摘要: An embroidery and applique machine having a number of article feeding modules, each adapted to supply articles such as sequins which are to be appliqued in alignment with a needle. The feeder modules are mounted on a carriage for movement therewith. A motor moves the carriage back and forth along a fixed path relative to the needles. An indexing mechanism is effective for stopping the carriage at any one of a number of positions in which the feeder modules are in register with the needles for supplying articles in alignment with a particular needle. A number of carriages may be provided at positions relative to the needles. A lost motion flange on the carriage contacts abutments on the indexing mechanism and enables the feeder modules on the carriage to register with the needles irrespective of the direction of movement of the carriage on the path.
