  • Publication number: 20210200124
    Abstract: A snap ring is set to a set portion of a shaft of a rotator from a direction orthogonal to an axial direction of the shaft. The snap ring includes a first arcuate portion and a second arcuate portion facing each other, being elastically deformable in directions away from each other, holding the set portion by elastic deformation restoring force. One ends of the first and second arcuate portions are away from each other to form an insertion portion to insert the set portion. When the snap ring is not used, the first arcuate portion has a same radius of curvature as the second arcuate portion and the set portion, and a center of curvature closer to the second arcuate portion than the first arcuate portion, and the second arcuate portion has a center of curvature closer to the first arcuate portion than the second arcuate portion.

  • Patent number: 10962558
    Abstract: An automatic analyzer is capable of ensuring sufficient nozzle cleaning and suppressing of deterioration in the accuracy of analysis. When it is judged that there remains no analysis item of the sample, a judgment is made on whether the sample dispensation quantity of the n-th sample dispensation is less than a dispensation quantity threshold value or not, and if less, a cleaning pattern is selected by making a judgment on whether or not all the sample dispensation quantities of the first through (n?1)-th sample dispensations are less than the dispensation quantity threshold value. If the sample dispensation quantity of the n-th sample dispensation is the dispensation quantity threshold value or more, another cleaning pattern selected by making the judgment on whether or not all the sample dispensation quantities of the first through (n?1)-th sample dispensations are less than the dispensation quantity threshold value.

  • Publication number: 20200292566
    Abstract: Please substitute the new Abstract submitted herewith for the original Abstract: The present invention reduces the turnaround time of an automated analyzer. During a period when cyclic measurement by a measurement unit is unnecessary, a controller washes a reaction vessel using a washing cycle having a cycle time shorter than that of an analysis cycle. A single analysis cycle and a single washing cycle both include a reaction disc stopping period and rotation period. In the washing cycle, there is no time during the stopping period when a sample dispensing mechanism, reagent dispensing mechanism, or stirring mechanism operates but there is a time when a washing mechanism operates. The washing cycle stopping period is shorter than the analysis cycle stopping period. The amount of rotation of the reaction disk in the analysis cycle rotation period is the same as the amount of rotation of the reaction disk in the washing cycle rotation period.

  • Patent number: 10162294
    Abstract: A fixing device includes an endless belt, a drive rotator, a driven rotator, a rotation detector, and circuitry. The drive rotator contacts and rotates the endless belt. The driven rotator contacts an inner circumferential surface of the endless belt. The rotation detector detects a rotational speed of the driven rotator. The circuitry is operatively connected to the rotation detector to control a rotational speed of the drive rotator based on the rotational speed of the driven rotator detected by the rotational detector. The circuitry changes the rotational speed of the drive rotator when a recording medium bearing a toner image is not conveyed over the endless belt.

  • Patent number: 10094844
    Abstract: In determining whether a rack inputted to the automatic analyzer by the user is to be transferred to an analysis section or not, samples existing in a route from a buffer to a sample dispensing position in the analysis section are identified, and the number of items in which suction by a nozzle has not been completed in analysis items requested for the samples is managed. When the number of items is reduced to be smaller than a given number, the conveyance of a next rack from the buffer to the analysis section is controlled, thereby limiting the number of analysis items requested for samples in a waiting state for analysis in the analysis section constantly to be smaller than a fixed number. As a result, a period of time until a measurement result of emergency samples is outputted can be reduced even when emergency samples are newly inputted.
