    Abstract: An automated light scattering photometer characterized in that a photoelectric unit used to measure the intensity of light scattered from the sample container at different angles relative to the optical axis of the instrument can be intermittently rotated. This can be achieved by the provision of a pair of switching means, one of which being adapted to be actuated by a pin vertically disposed on the upper surface of a rotary member mounted with said photoelectric unit and the other of which being adapted to be actuated by an actuator means rigidly mounted on a shaft for transmitting the rotational force from a motor to the rotary member. When these switches are closed at the same time, the rotation of the rotary member can be stopped by means of a clutch means. In addition, this photometer of the present invention can be utilized in connection with a commercially available computing machine. To this end, means for integrating the output of the photoelectric unit and that of another photoelectric unit is provided, the output of said integrating means being adapted to be applied to the computing machine.

    Abstract: PROBLEM TO BE SOLVED: To estimate an interface position between a plasma layer and a blood cell layer by a simple method. SOLUTION: A specimen dispensing mechanism 2 has a liquid level detecting means for sucking blood specimen filled in a specimen container, centrifugally separated and installed at a predetermined position, dispensing it in a blood analyzer and sensing a liquid level position at its end. A blood cell layer position estimating unit 4 estimates an interface position between a plasma layer and a blood cell layer in the container based on type of the container, the liquid level position sensed by the detecting means and a hematocrit value previously set or measured. A dispensing mechanism controller 6 decides a drop amount of the mechanism 2 based on the interface position estimated by the unit 4 when the specimen of the blood cell layer is sucked in the case of controlling the dispensing by the mechanism 2.

    Abstract: PURPOSE:To obtain an analyzer, by which anybody can simply pick up cross- contamination data between reagents even if using conditions are changed. CONSTITUTION:An analysis requesting pattern, wherein an analyzing sequence for checking cross-contamination between reagent distributing devices 7 and 10 for a predetermined number of channels and a cell 5 is determined, is stored in a memory part and allocation of channels to respective items is designated. Thus, the cross-contamination between the reagents among all items is measured by repeating this steps.

    Abstract: PURPOSE:To allow the automatic equal distribution of measuring items to plural measuring units by determining the measurement number of the respective measuring units in such a manner that the measurement number is approximately equaled in accordance with measuring frequencies for the selected measuring items. CONSTITUTION:A measuring item setting section 4 selects the items to measure when the items are selected from an input device 3 and are set in the measuring item setting section 4. The frequencies % of the respective items are then calculated from the frequency coeffts. previously stored for the selected items in a measuring frequency memory section 1 or the measurement number of every item per month inputted in this facility. An equal distributing section 5 distributes the items equally to the set units in such a manner that the measurement number can be balanced between the measuring units in accordance with the frequencies of the selected items from the measuring frequency memory section 1. The measuring sequence within the measuring units of the items equally divided to the respective measuring units is determined in a measuring sequence determining section 6.

    Abstract: PURPOSE:To exactly determine a desired component by mixing a prescribed reaction reagent with a sample liquid to effect reaction, determining an estimated optical density value at the time of the start of the reaction by the regression equation obtd. by a method of least squares from the plural actually measured optical density values and determining an actually measured optical density value at the time of the end of the reaction. CONSTITUTION:The prescribed reaction reagent is mixed with the sample liquid. The absorbance data is determined from the right after the start of the reaction in an absorbance fluctuating region A and the quadratic regression equation y=at +bt+c is determined by the method of least squares with the measurement groups from alpha to beta thereof. The value of t=0, i.e., y0 at the time of the start of the reaction is determined from this equation. The absorbance ys in the absorbance stationary region B after the end of the reaction is actually measured to determine ys-y0 and the concn. is calculated therefrom.

    Abstract: PURPOSE:To rapidly and simply stirr a distributed solution after the distribution of a reagent by together providing stirring function to a reagent distribution apparatus. CONSTITUTION:The up-and-down moving means 6 of a reagent distribution and stirring apparatus 1 is driven by a moving mechanism and the nozzle part a2 of a nozzle pipeline (a) falls and the corrugated deformed part (x) of the nozzle part is inserted in the reaction tube 7 at a distribution position. A predetermined amount of a reagent for starting reaction is emitted and distributed in the reaction tube 7 from the nozzle at the leading end of the pipeline (a) by driving a syringe pump 32. Thereafter, the pulse motor 55 of a stirring mechanism 5 is intermittently and repeatedly rotated forwardly and reversely, and the pipeline shaft from the elastic deformable part a1 of the pipeline (a) to the nozzle part thereof is repeatedly revolved through gears 54, 53 while supported in a twisted state at the deformable part a1 in a forward and reverse direction. With this operation, the deformed part (x) is revolved in the reaction tube 7 to stirr and mix a specimen and the reagent.
