[Problem]To provide an automatic analyzer capable of more precisely detecting deficiency and excess of liquid within a reaction container.[Solution]An automatic analyzer, comprises: a nozzle that is immersed in a liquid stored in a container and that aspirates the liquid; a detection unit that detects inflow of the air into the nozzle when aspirating liquid stored in the container: and a control unit that controls each operation of insertion of the nozzle into the container, immersion of the nozzle into the liquid, aspiration of the liquid by the nozzle, and detection of the air by the detection unit, In the automatic analyzer, the control unit inserts the nozzle into the container to a position where a distal end of the nozzle is exposed from the liquid when the nozzle is immersed in the liquid of the container and aspirates the liquid of an amount required for an analysis.

An object of the present invention is to provide an automatic analyzer capable of generating ultrasonic waves from different piezoelectric elements without reducing the intensity of the ultrasonic waves. Therefore, the present invention provides an automatic analyzer including: a piezoelectric element configured to generate ultrasonic waves for stirring a sample and a reagent; an amplifier configured to drive the piezoelectric element; a relay switch provided between the piezoelectric element and the amplifier; and a control unit configured to control the amplifier and the relay switch. When a first piezoelectric element is driven, the control unit turns on a positive voltage-side switch and a GND-side switch in a first relay switch provided between the first piezoelectric element and the amplifier, and turns off a positive voltage-side switch and a GND-side switch in a second relay switch provided between a second piezoelectric element and the amplifier, and when the second piezoelectric element is driven, the control unit turns on the positive voltage-side switch and the GND-side switch in the second relay switch, and turns off the positive voltage-side switch and the GND-side switch in the first relay switch.

A battery state diagnosis method and a battery state diagnosis device are provided, which achieve a highly accurate battery capacity deterioration diagnosis when a diagnosis target is a battery system, such as a battery system using a LiFePO<4>-based active material for the positive electrode, that exhibits little voltage change in response to a change in the state-of-charge. A battery state diagnosis method is for diagnosing a deterioration state of a secondary battery mounted on equipment, and includes: a data acquisition step of acquiring pieces of data about a voltage, a current, and a temperature of the secondary battery from the equipment in operation; a table creation step of creating, based on the acquired pieces of data, a table including a state of health capacity and a state of health resistance of the secondary battery; and a diagnosis step of diagnosing, using the created table, a deterioration state of the secondary battery.

This automatic analysis device calculates, for each of a plurality of analysis tanks 106, a target number of uses of the analysis tank per predetermined period of time on the basis of the number of remaining executable measurements of an ion selective electrode 112 and a remaining period of time up to an expiration date thereof, and when there are a plurality of analysis tanks usable for an analysis request, determines a ratio of usage for each analysis tank on the basis of a ratio of the target number of uses of each of the plurality of analysis tanks usable for the analysis request. This allows as many of the number of remaining executable measurements as possible to be used in the automatic analysis device comprising the plurality of analysis tanks before the expiration date of the ion selective electrode.

In the prior art, the reliability of a measurement result is lowered by the deterioration of an ISE reagent remaining in a flow passage in the standby time of an electrolyte analysis unit. To solve this problem, when receiving an instruction to measure a patient sample requiring measurement using an electrolyte analysis unit 8, this automatic analysis device 1 determines deterioration of a residual reagent remaining in the flow path of the electrolyte analysis unit prior to measurement of the patient sample when the standby time of the electrolyte analysis unit is equal to or greater than a predetermined time.

To provide: a device which performs spectroscopic measurement on a suspension liquid handled in the field of pharmaceutical products, foods, or chemistry without taking out the suspension liquid from the inside of a pipe, and is capable of accurate measurement even when the device is attached to pipes of various shapes and materials; and a measurement condition adjustment method, the following configuration is adopted. A measurement device for measuring an optical spectrum of a liquid flowing in a pipe provided with a window material includes: a measurement probe having a light irradiation unit and a light reception unit; and a movement mechanism for moving the measurement probe, in which the movement direction of the measurement probe includes a rotation angle for changing the direction of the probe and a direction different from the axial direction of the pipe. The position of the measurement probe is adjusted by using both or one of the S/N ratio and the intensity of the measured values at the wavelength of interest.

An image processing device includes an input unit to receive an input image, a feature amount extraction unit to extract a feature amount from the input image, an object region detection unit to detect an object region in the image through use of the feature amount, an object end-point estimation unit to estimate coordinates of an end point of an object in the object region, an object bridging unit to calculate a trajectory complementing a space between end points in two object regions on the input image, a same-object determination unit to determine, from luminance value transition on the trajectory, whether the two object regions are included in the same object, an object region correction unit to correct the object region output by the object region detection unit based on a determination result output by the same-object determination unit, and an output unit to output the corrected object region.

An automatic analyzer that uses reaction between a sample and a reagent to analyze the sample, comprises: a storage part that includes a first part capable of transmitting light from outside, and a second part capable of transmitting light to outside, and that is capable of housing a plurality of consumables for use in the automatic analyzer; a light emitting part that is located outside the storage part and radiates first light into an inside of the storage part through the first part; a first light receiving part that is located outside the storage part and receives second light from inside the storage part through the second part; and a controller that judges that the storage part is in a full load condition if an amount of light received by the first light receiving part is larger than a previously determined threshold. Accordingly, it is possible to suppress erroneous detection caused by diffuse reflection of light and accurately detect a full load condition.
