Abstract: A graphene nanostructure has a nanographene, a ? conjugated functional group bonded to the nanographene via a pyrazine skeleton, and at least one Br group and/or at least one CN group introduced into the ? conjugated functional group. A graphene nanostructure preferably has an average size of 1 nm or larger to 100 nm or smaller, a band gap of 0.01 eV or higher to 1.2 eV or lower, and/or a HOMO level of ?6.0 eV or higher to ?4.0 eV or lower. As the ? conjugated functional group into which the Br group(s) and/or the CN group(s) are/is introduced, a 4-bromobenzene group, a 4,5-dibromobenzene group, a 5-bromopyridine group, a 5-bromopyrazine group, a benzonitrile group, a phthalonitrile group, or a 2,3-dicyanopyrazine group is desirable.

Abstract: An accelerator position detection device includes a handlebar grip that is turnable in a normal rotation direction and in a reverse rotation direction from a neutral position and is energized to the neutral position when no operation is applied; accelerator position sensors that output voltage according to an angle of the handlebar grip and that include a first sensor and a second sensor; and a detector that detects an angle for control for controlling a vehicle on the basis of the angle of the handlebar grip according to output from the accelerator position sensors. The detector detects an angle as a positive value on the basis of a first voltage when the first voltage in a rising range is output, and the detector detects an angle as a negative value on the basis of a second voltage when a first initial value not located in the rising range is output.

Abstract: A light emitting body has a base material containing a graphene structure and a covering material for covering a surface of the base material. The graphene structure preferably includes a sheet portion made of a monolayer or multilayer graphene nanosheet and having, at an edge portion thereof, an armchair edge-face portion; and a terminal six-membered ring bound to the armchair edge-face portion while sharing only one side therewith. Further, the graphene structure preferably includes a nitrogen-containing functional group bound to any one or more carbon atoms selected from (a) carbon atoms constituting the terminal six-membered ring but not bound to the armchair edge-face portion, and (b) carbon atoms constituting the sheet portion (including carbon atom on the side shared with the terminal six-membered ring).

Abstract: A nitrogen-containing graphene structure has a graphene structure including a monolayer or multilayer graphene nanosheet and nitrogen introduced into the graphene structure. The nitrogen-containing graphene structure preferably includes the above-described graphene structure having a sheet portion comprised of a monolayer or multilayer graphene nanosheet and containing, at an edge portion thereof, an armchair edge-face portion and a terminal six-membered ring bound to the armchair edge-face portion while sharing only one side therewith; and a nitrogen-containing functional group bound to any one or more carbon atoms selected from (a) the carbon atoms constituting the terminal six-membered ring but not bound to the armchair edge-face portion, and (b) the carbon atoms constituting the sheet portion (including the carbon atom on the side shared by the terminal six-membered ring). A phosphor dispersion is a dispersion of such a nitrogen-containing graphene structure in a solvent.

Abstract: In a multiprocessor exchange having a floating function, a signal distribution control processor is provided between a plurality of call control processors and a plurality of line controllers, and lines or highways are allocated to the call control processors on the basis of the line allocation information which is input from a terminal apparatus. The signal distribution control processor distributes the call control information on a predetermined line which is input from a line controller to the call control processor corresponding to the line by reference to the line allocation information, and distributes the call control information input from a call control processor to the corresponding line controller.
