Abstract: A light emitting element of one or more embodiments includes a first electrode, a second electrode oppositely to the first electrode, and an emission layer between the first electrode and the second electrode. The light emitting element of one or more embodiments includes a polycyclic compound represented by a specific chemical structure in the emission layer, thereby showing improved emission efficiency and life characteristics.

Abstract: A heating apparatus, an image forming apparatus, and a liquid discharge apparatus. The heating apparatus includes a heating roller having a heat source inside, an end holder in which a portion of the heat source is disposed, the end holder holding an axial end of the heating roller rotatably, and an air supply device configured to supply air into the end holder in a direction intersecting with an axial direction of the heating roller. The heating apparatus includes a heating roller having a heat source inside, and an end holder in which a portion of the heat source is disposed, the end holder rotatably holding an axial end of the heating roller. In the heating apparatus, the end holder has an air inlet opening through which air is supplied into the end holder and an air outlet opening through which air is ejected outside from inside the end holder.

Abstract: A power system stabilization device for the stabilization control of a power system, includes an indicator calculation unit for calculating an acceleration index, which is an index representing the acceleration of a generator for supplying electric power to the power system, by using the generator output, which is the output of the generator, and the generator phase difference that indicates the temporal change of the phase angle of the generator output; a threshold value determining unit for determining whether or not the acceleration index exceeds a preset threshold value; and a control command unit for generating a control command for control details that constitute a correction to the stabilization control, set in advance for the threshold value, when the acceleration index exceeds the threshold value.

Abstract: In an embodiment, a command is received that designates a base shape. A navigation order of a plurality of shapes relative to the base shape is determined, where the plurality of shapes are adjacent to the base shape. The navigation order is presented by presenting identifiers of the plurality of shapes and an ordered sequence of the plurality of shapes. Focus is moved between the plurality of shapes in the navigation order after the navigation order is presented.

Abstract: An optical element is constituted by providing an optical waveguide formed with a piezoelectric material, a photonic crystal structure provided within the optical waveguide, a pair of control electrodes, which are provided so as to sandwich the upper and lower surfaces of the optical waveguide, for applying a voltage to the optical waveguide and supporting parts formed at the both ends of the lower control electrode.

Abstract: A core layer contains photonic crystals formed by ferroelectric members made of a ferroelectric substance and periodically disposed along a one-dimensional direction or two-dimensional directions. Electrodes apply an electric field to the core layer. An optical function device is provided which can be made compact and can set a wavelength at high speed.

Abstract: A novel fine carbon wire includes a needle-like fullerene crystal having a smooth surface. The fine carbon wire can be produced by a method including the steps of (1) adding a solution containing the fullerene dissolved in a first solvent to a second solvent having less solvency for the fullerene than the first solvent; (2) forming a liquid-liquid interface between the solution and the second solvent; and (3) depositing a fine carbon wire at the liquid-liquid interface.

Abstract: An abrasive sheet for fine texture processing has threads planted uniformly on a surface of a flexible base sheet and abrasive particles are attached by a binder to each of these threads uniformly over a specified distance from the tip such that the threads remain free to move independently without getting stuck to each other. Such an abrasive sheet can be manufactured by gravure processing with the separation between a gravure roller and a back roller adjusted according to the distance over which a coating material including the abrasive particles can be applied to the threads.
