Abstract: With a mounting operation of a supply container, a supported portion 11b of a developer receiving portion 11 is supported by a receipt supporting portion 30c of a lifting portion 30. With further mounting operation, a shutter sliding portion 30b of the lifting portion 30 slides on a shutter inclined portion 4f of a shutter 4. The developer receiving portion 11 is displaced so as to bring a receiving opening into communication with a discharge opening by operating, using the shutter 4, the lifting portion 30 supporting the supported portion 11b of the developer receiving portion 11. By this, a load required for movement of the developer receiving portion 11 is reduced to achieve smooth mounting of the supply container.

Abstract: A method adapts a resonant frequency of a first filter of a closed control loop to a given frequency. The method includes feeding an output signal of a delta sigma modulator of the closed control loop into a frequency adaptation circuit and determining a first noise spectrum of the output signal in a first frequency band and a second noise spectrum of the output signal in a second frequency band.

Abstract: When a flow path switch valve is in a first flow path state, an aqueous solvent supplied by an aqueous solvent supplier is guided to a first flow path, and a pH of the aqueous solvent is measured by a pH meter provided in the first flow path. When the flow path switch valve is in a second flow path state, the aqueous solvent supplied by the aqueous solvent supplier is guided to a second flow path. A sample to be analyzed is supplied by a sample supplier at a position farther downstream than the flow path switch valve. The solvent that has passed through the second flow path and the sample supplied by the sample supplier are guided to a separation column. The sample that has passed through the separation column is detected by a detector.

Abstract: A display area 60 of a display unit of a mass spectrometer shows a result of tuning. The display area 60 includes: a tuning-item displaying section 62 configured to display all tuning items and a result of whether each tuning item has been tuned; and an analyzable-condition displaying section 63 configured to display a condition under which an analysis is possible based on the result. The tuning items may be displayed respectively and individually. Alternatively, the tuning items may be displayed in a grouped manner with a plurality of tuning items in a group. Consequently, a user knows, at a glance, whether the tuning necessary for an analysis that the user intends to perform has been performed. If a necessary tuning item has not been tuned, the user immediately starts to tune (only) the tuning item. Further, a user immediately knows in a current state of tuning whether the analysis that the user intends to perform is possible. Therefore, when the analysis is possible, the user can start the analysis.
