Abstract: An automatic analyzer performs a dispensing operation with high throughput while reducing a risk of carry-over of a reagent that includes first and second dispensing operations. The second dispensing operation includes a first procedure of aspirating a sample accommodated by a dispensing nozzle, a second procedure of discharging the aspirated sample to a first reaction container, a third procedure in which a cleaning tank cleans an inner side and an outer side of the dispensing nozzle after the second procedure, a fourth procedure of aspirating the reagent accommodated in a reagent container after the third procedure, a fifth procedure B5 in which the cleaning tank cleans the outer side of the dispensing nozzle after the fourth procedure, a sixth procedure of aspirating the sample accommodated in the first reaction container after the fifth procedure, and a seventh procedure of discharging the reagent and the sample to a second reaction container.

Abstract: A voltage detection probe includes an electrode configured to detect a voltage applied to a wire, and a clip portion freely attachable to and detachable from the wire. The clip portion has a fitting concave portion into which the wire is to be fitted, the clip portion being elastically deformable to widen an opening of the fitting concave portion. The clip portion is configured to retain, by an elastic force, the wire fitted through the opening into the fitting concave portion to cause the electrode to be disposed along an outer peripheral surface of the wire.

Abstract: Provided is an automatic analysis device that reduces the used water amount when cleaning the outside of a probe. An automatic analysis device, including a probe that performs suction and discharge of a sample or a reagent and a cleaning nozzle that discharges cleaning water toward the outside of the probe, includes a first discharging step of starting discharge of the cleaning water from the cleaning nozzle when the tip of the probe is at a first height position and a second discharging step of starting discharge of the cleaning water from the cleaning nozzle when the tip of the probe is at a second height position higher than the first height position, and is provided with a discharge stopping step of stopping the discharge of the cleaning water from the cleaning nozzle between the first discharging step and the second discharging step.

Abstract: An automatic analysis device improves the uniformity of a mixed liquid by noise agitation by a dispensing mechanism. The dispensing mechanism agitates a mixed liquid by suctioning the mixed liquid into a reaction vessel by a nozzle and then re-discharging the suctioned mixed liquid into the reaction vessel. When the mixed liquid is re-discharged into the reaction vessel, the nozzle is moved upward at a speed higher than a speed at which the liquid surface of the mixed liquid rises due to the re-discharging of the mixed liquid from the nozzle during a first period and lowers the speed of moving the nozzle upward than the speed during the first period while maintaining or reducing the speed at which the liquid surface of the mixed liquid rises due to re-discharging of the mixed liquid from the nozzle during a second period following the first period.

Abstract: A power measurement apparatus includes a voltage detector, current detector, and power calculator. The voltage detector contactlessly detects an AC voltage of a conductive path to which power is supplied from an AC power source having a magnitude of AC voltage regulated to be a predetermined value, and outputs a first data signal regarding a voltage waveform of the AC voltage of the conductive path. The current detector contactlessly detects an AC current flowing through the conductive path, and outputs a second data signal regarding a current waveform of the AC current of the conductive path. A power calculator receives the first and second data signals, and calculates active power of the conductive path from a product of a second instantaneous voltage and an instantaneous current of the current waveform indicated by the second data signal. The second instantaneous voltage is generated by converting a first instantaneous voltage.

Abstract: An air conditioning capacity presenting system presents a capacity of an air conditioning apparatus including at least one outdoor unit, at least one indoor unit, and a connection pipe that connects the outdoor unit and the indoor unit. The air conditioning capacity presenting system includes first acquisition unit, a measurement unit, a second acquisition unit, and a capacity calculating unit. The first acquisition unit acquires outdoor unit capacity information, which is a rated capacity of the outdoor unit or information related to the rated capacity. The measurement unit measures power consumption of the outdoor unit. The second acquisition unit acquires an outside air temperature, which is a temperature of air around the outdoor unit. The capacity calculating unit obtains a calculation value of the capacity of the air conditioning apparatus based on the outdoor unit capacity information, the power consumption, and the outside air temperature.

Abstract: A method for measuring LDL cholesterol in a sample using a test piece is provided which involves a step of measuring the total cholesterol in the sample; a step of measuring the non-LDL cholesterol in the sample; and a step of subtracting the non-LDL cholesterol value from the total-cholesterol value to obtain the LDL cholesterol level.

Abstract: An LDL cholesterol measurement method that can be used with a test piece is provided. The LDL cholesterol measurement method for measuring LDL cholesterol in a sample has (A) a step of providing a total-cholesterol measurement portion and a non-LDL cholesterol measurement portion for measuring non-LDL cholesterol, which is cholesterol other than LDL cholesterol; (B) a step of measuring the total cholesterol in the sample in the total-cholesterol measurement portion; (C) a step of measuring the non-LDL cholesterol in the sample in the non-LDL cholesterol measurement portion; and (D) a step of obtaining the LDL cholesterol level in the sample by subtracting the non-LDL cholesterol value measured in the step (C) from the total-cholesterol value measured in the step (B).
