Abstract: An ICP-MS includes a control device, a collision cell and a first electrode that are provided on an optical axis of plasma, and a second electrode, a mass separation device, and a detector that are provided on a detection axis. The control device sets, as an axis-shifting voltage to be applied to each electrode of the first electrode and the second electrode in a gas-present mode, the voltage obtained by adding an offset determined according to a mass-to-charge ratio of a target ion to an initial voltage in a gasless mode.

Abstract: Provided is a mass spectrometer including a vacuum chamber containing a cell used for causing ions originating from a sample to come in contact with a predetermined gas supplied from a gas supplier (20), which includes a three-way valve (204) configured to selectively send the gas into either a first passage (22) for sending the predetermined gas to the cell or a second passage (23) for discharging the gas into vacuum state. The mass spectrometer also includes a controller configured to control the three-way valve so as to send the gas into the second passage during an analysis period in which ions are not caused to come in contact with the gas within the cell and/or during a non-analyzing period, as well as to send the gas into the first passage during an analysis period in which ions are caused to come in contact with the gas within the cell.

Abstract: Picture signals that indicate a screen that are supplied as output from a signal generation source are divided by a picture splitting device into picture signals of a plurality of screens for displaying a large screen and then supplied to a gradation conversion LUT unit in a luminance correction circuit. Based on display position information from a timing circuit, a coefficient arrangement control unit implements a non-linear arrangement of gain coefficients for gradation control that is carried out in picture element units. Based on the display position information from the timing circuit, the gradation conversion LUT unit adjusts display positions such that areas in which the projected display areas of the plurality of projectors overlap match with areas that are the objects of gradation conversion, and implements a luminance level conversion in picture element units of input signal levels of picture signals that have been split using the arrangement of gain coefficients for gradation control.

Abstract: A method of correcting color purity is provided for reducing differences in picture quality between film images and television receiver images by the video signals, thus enabling reproduction of picture quality that approximates images that are shown in a movie theater. When outputting signal levels of each of the color components of video signals, color mixing is performed in which the output signal level is the sum of products of all of the color component levels that have been received as input multiplied by coefficients. By setting these coefficients within the range −0.3 to 0.3, the influence from other colors can be limited to prevent excessive change from the colors of the original image.
