Abstract: The toner contains binder resin-containing toner particles and silica fine particle S1, wherein the weight-average particle diameter of the toner is 4.0-15.0 ?m, both inclusive, peaks originating with the silica fine particle S1 are observed in 29 Si-NMR measurement of the silica fine particle S1, and, in the spectrum obtained by 29Si CP/MAS NMR or 29Si DD/MAS NMR, the peak area of a peak corresponding to the D1 unit structure in the silica fine particle S1, the peak area of a peak corresponding to the D2 unit structure in the silica fine particle S1, and the peak area of a peak corresponding to the Q unit structure in the silica fine particle S1 satisfy a prescribed relationship.

Abstract: In a case where a specific position is designated in first road network data, first link group identification data containing a link, on which the specific position is present, is acquired, and a corresponding link group, which is a link group indicated by second link group identification data, corresponding to the first link group identification data, is extracted from second road network data. A corresponding position on a link contained in the corresponding link group, which corresponds to the specific position, is determined, and second information is acquired from second map data based on the corresponding position.

Abstract: In a case where a specific point is designated on a map, extracted structure data, which is data of structures contained in an extraction range defined in advance with respect to the specific point as a datum, is extracted from map data. In a case where multiple extracted structure data items are extracted, at least one structure, the evaluated value of which is different from evaluated values of other structures by a selection threshold value or greater for a selection index, is selected as a landmark structure. A three-dimensional map image containing at least a road image and a structure image is displayed on a display screen in an emphasized manner such that the selected landmark structure offers visibility higher than visibility non-emphasized structures.

Abstract: A reactor water level measurement system including: a condensation tank connected with a steam region of a pressure vessel; a reference pipe with one end connected with the condensation tank; fluctuation pipes with one end connected with the pressure vessel; pressure difference measurement type water gauges that detect the water head difference of the reference pipe and the fluctuation pipes and that are connected with the other ends of the reference pipe and the fluctuation pipes; non-pressure difference water gauges that detect the water level of the pressure vessel; and a computation device that selects a pressure difference type water gauge or a non-pressure difference type water gauge, in accordance with a condition of the containment vessel or of the pressure vessel and that indicates/records the water level of the pressure vessel based on the detection result of the selected water gauge.
