  • Patent number: 7700043
    Abstract: A plurality of analyzer units for serum, a plurality of analyzer units for blood plasma and a plurality of analyzer units for urine are arranged along a main transfer line for transferring a sample rack from a rack providing portion to a rack storage portion. A reagent bottle for inspecting liver function is contained in each reagent delivery mechanism of two analyzer units among the plurality of analyzer units for serum. When the reagent for inspecting liver function in one of the two analyzer units is to be short, analysis for the liver function analysis item to samples can be continued by transferring a sample rack from the rack providing portion to the other analyzer unit.

  • Patent number: 6643823
    Abstract: The waveform generating circuit according to the present invention includes a data selector (105) and edge selectors (107, 109). The data selector (105) inputs two data having the same bit number as input data (111, 113) and divides the total bit number (2N) of the inputted two data into two data on a basis of a setting value (&agr;). The edge selector (107) generates in response to a timing edge (117), as an output waveform (119), the waveform corresponding to a first data (115) which is one of the two divided data of the total bit number. The edge selector (109) generates in response to a timing edge (123), as an output waveform (125), the waveform corresponding to a second data (121) which is the other of the two divided data of the total bit number.

  • Patent number: 6117392
    Abstract: A sample of a sample rack is sampled at analyzing units in the middle of a transfer line. A standby unit and a rack collecting unit are arranged near an exit of the transfer line. After sampling, sample racks are sorted out to the standby unit or the rack collecting unit at a first switching unit. The racks contained in the standby unit are sorted out to a returning line or the rack collecting unit in a second switching unit corresponding to a judged result of whether or not reexamination is required.

  • Patent number: 6019945
    Abstract: A sample analysis system includes blood serum analysis units, blood plasma analysis units and urine analysis units which are arranged along a main conveyor line. The width size of each analysis unit on the side along the main conveyor line is the same. Each analysis unit can be removed integral with a sampling line and its rack transfer device from, the main conveyor line. Removed analysis units can be replaced by each other without changing the entry and exit positions for the sample rack. The conveyor line has the same number of line frame segments as the number of the analysis units.

  • Patent number: 5827479
    Abstract: A reagent containing device has an outer bottle holder and an inner bottle holder. The holders are rotated independently of each other. When an instruction for exchanging reagent bottles inside the reagent containing device is input, a first reagent bottle on the outer bottle holder and a second reagent bottle on the inner bottle holder relating to the same analysis item are positioned at an opening of a bottle exchanging area. Then the opening is opened by a sliding operation of a lid so that the first reagent and the second reagent bottles can be unloaded through the opening.

  • Patent number: 5051238
    Abstract: An automatic analyzing system has a sample table for supporting a plurality of sample vessels and a reagent table for supporting a plurality of reagent vessels. The sample table and the reagent table are fixed to a common drive shaft. The system further has a rotatable reaction table for supporting a plurality of reaction vessels. The reaction table is arranged in a side-by-side relation to the sample table and the reagent table. The system further has a single pipetting device disposed between the reaction table and the stack of the sample table and the reagent table for a swinging motion therebetween so as to suck samples and reagents from the sample vessels and the reagent vessels and to deliver the same to the reaction vessels. The pipetting device is operated in such a manner as to transfer all the samples to the reaction vessels followed by the supply of the reagents to these reaction vessels.
