Abstract: A sample measurement device (110), in which a biosensor (30) having an electrode is mounted, voltage is applied to the electrode, and the concentration of a specific component in a sample deposited on the biosensor (30) is measured, comprises a voltage source (19) configured to apply voltage to the electrode, a time measurement component (22), and a controller (18) configured to control the voltage to be applied and measure the concentration of the specific component. The time measurement component (22) measures a detection time, which is the length of time between the mounting of the biosensor (30) and the deposition of a sample on the biosensor (30). The controller (18) changes a set value for measuring the concentration of a specific component according to the detection time. Consequently, measurement accuracy can be improved regardless of the temperature of the biosensor (30).

Abstract: A discharge rate control method for an ink-jet printer (1) includes forming a film (B) on a coating article (2) having a non ink-absorbent characteristic. Ink is discharged on coating article (2) from a plurality of nozzles (4) of a print head (3). The film thickness of film (B) is measured, corresponding to ink discharge positions of each nozzle (4). The discharge rate of ink is corrected for each nozzle (4) by increasing or decreasing the discharge rate based on differences between a target film thickness (Ba) and a film thickness at an ink discharge position of each nozzle (4).

Abstract: A battery pack updating method updates firmware stored in internal control circuit memory via an update signal sent from a main device that supplies power. When battery pack memory is updated, an AC adapter is connected to the main device, and power is supplied to the main device from the AC adapter. The updating method transmits a charging and discharging blocking signal from the main device to the battery pack control circuit via a communication line. The charging and discharging blocking signal stops discharge from the battery pack rechargeable battery, and stops charging of the rechargeable battery. With rechargeable battery discharging and charging to and from the main device stopped by the charging and discharging blocking signal, the updating method transmits update data from the main device to the battery pack control circuit to update memory.
