摘要： In a blade lattice structure for an axial fluid machine including circumferentially arranged stationary blades and upper and lower side walls having the stationary blades secured thereto for defining therebetween a flow path which is arranged annularly, the stationary blades each have a cross sectional shape such that the thickness of each stationary blade gradually increases in going toward the upper side wall from an arbitrarily selected position on the blade in its height, so that the area of a throat for each section of the stationary blade is varied along the height thereof to thereby increase stage efficiency.

摘要： The present invention provides an axial flow turbine, comprising a diverging flow channel for flowing of an elastic fluid, and stationary blades which are fixed at the diverging flow channel wall and are curved in a perpendicular direction to the flow direction of the elastic fluid, characterized in forming the same tangential lean angles at the leading edge and the trailing edge of the stationary blade corresponding to the flow direction of the elastic fluid, and an axial flow turbine having the stationary blades thereof. The stationary blade makes distribution of the fluid in the flow channel uniform and, consequently, improves the efficiency of the flow.

摘要： The invention relates to an automatic analysis device in which a part-replacement assessment region assesses whether or not the present time has reached a replacement datum of a component of the automatic analysis device. As soon as it results that the present time has reached this replacement datum, the part-replacement assessment region outputs a command for displaying a warning which specifies the replacement of a component on a cathode-ray tube. A K-factor updating region assesses whether the component to be replaced influences the K factor and whether the K factor should be updated. If the K factor should be updated, a warning is displayed on the cathode-ray tube which warning indicates the updating of the K factor. This warning is displayed until the K factor is updated. Furthermore, various types of standard protocols are carried out automatically. If a start button of an input device is actuated, an image display illuminates on the cathode-ray tube with a selection of standard protocols. If an operator inputs a number which corresponds to one of the protocols, a selected image display appears, showing the corresponding standard protocol. If the operator inputs information which specifies a reaction-inducing substance to be evaluated, an analysis reagent number, a dilution-sequence number and the number of measurements, the measurement is started.

摘要： : Each of a series of nozzle blades constituting a stage of an axial-flow rotary machine, e.g. a turbine, has its rear edge so modified in shape that a chord length thereof is greatest in a central part of the blade length and gradually decreases towards the blade end parts away from the central part. The clearance from an outlet end of the turbine nozzle to an inlet end of a turbine impeller located on a wake flow side in the axial direction becomes smallest in the central part of the blade length of the turbine nozzles and gradually increases towards the blade end parts away from the central part.

摘要： A turbine blade in which the crossing point of extensions of the blade inlet angle and the blade outlet angle is located in a position in which the distance between the blade outlet end and a line passing through the crossing point and parallel to the axis of a blade cascade arranged in a circle is more than one-half and less than four-fifths the blade width, and in which the ratio of the narrowest width S1 of a flow channel defined between the back side of the blade in a position in which the line crosses the back side of and the front side of an adjacent blade to the narrowest width S2 of the flow channel at the blade outlet end is 1 ? S1/S2

摘要： The invention has an object of enhancing the service capacity and the operability of a network and simplifying the maintenance and control of the network by adopting a size automatic change mode after a path is set and providing arbitrary pathsize at arbitrary time. To achieve the object, the following means is provided. The service capacity and the operability of a network are enhanced and the maintenance and control of the network are simplified by adopting a size automatic change mode that the size of an input path signal conforms to information written to line overhead H1 and H2 bytes and an output path signal is transmitted with the pathsize the same as the size of the input path signal. A case that receiving path size changes exceeding a band and the fault of a path is caused occurs by providing both modes of fixing pathsize and automating pathsize to a user, flexibly corresponding to various service and automatically changing pathsize. At this time, an operation system identifies the cause, analyzes an influenced range and realizes the simplification of the maintenance and control of the network.

摘要： A steam governing valve includes a valve body constituting a main valve together with a main valve seat formed on a casing body and having a smaller valve seat inside thereof, a valve rod movable in the valve body in an axial direction of the valve and constituting a smaller valve together with the smaller valve seat, a sleeve arranged in the casing body and guiding the valve body in an axial direction, and a pressure room defined by the casing body, the valve body and the sleeve, the pressure room being communicated with an entrance room through the valve body, and the main valve being opened by lifting the valve rod beyond the full open position of the smaller valve. The valve body is formed on the cylindrical outer surface thereof with a plurality of axially extending grooves arranged at equal intervals in a circumferential direction. The sleeve is formed with a plurality of stream passages at positions opposite to the axially extending grooves and the pressure room is communicated with said entrance room through the stream passages and the axially extending grooves when the valve body is lifted beyond a predetermined valve opening degree.
