摘要： PROBLEM TO BE SOLVED: To reduce the consumption of a sheath solution by preventing the contamination of the sheath solution with a sample solution. SOLUTION: Capillary tubes 11 and 12 having openings which are faced oppositely to each other at positions on the insides of both ends of a transparent thin tube section 31 are arranged on the center axis line of the tube section 31 and the suction side of a pump 51 is connected to the tube 12. The suction side of another pump 52 is connected to the end of the section 31 on the tube 12 side through a flow passage 44 and the discharge side of the pump 52 is connected to the end of the tube section 31 on the tube 11 side through another flow passage 40. In addition, a first detector 6 which measures particles is installed to the tube section 31 and the circulating flow of a sheath solution which flows to the tube 12 side of the tube section 31 from the tube side 11 of the tube section 31 is formed in a closed loop of the flow passage 40, tube section 31, flow passage 44, and pump 52. At the same time, a sample solution is made to flow from the tube 11 and sucked with the pump 51 connected to the tube 11. The flow rates of the pumps 51 and 52 are adjusted so that the circulating flow of the sheath solution in the tube section 31 and the flow of the sample solution to the tube 12 from the tube 11 may become laminar flows.

摘要： PURPOSE:To support an operation at a normal time or a non-normal/abnormal time by effectively using past history. CONSTITUTION:The history patterns of various measurement information are learnt from a pattern file by a neural processor 70 in a learning process and the operation is supported based on a learnt result in a supporting process. Knowledge and a knowledge candidate are extracted from the learnt result in a knowledge extraction process, and whether the knowledge candidate is appropriate or not is diagnosed in a knowledge diagnosis process. Then, the operation is supported based on a knowledge group obtained in this learning and that which is previously inputted in an operation supporting process. A system processor 42 executes these processes, operates a keyboard 44 and a display 46 as necessary and accesses to a knowledge base 60A and a knowledge candidate base 60B. Thus, a highly precise operation supporting system can comparatively easily be constituted.
