Abstract: Achieving an imaging apparatus capable of performing both photographing of visible light and photographing of invisible light with a normal solid-state imaging element used for visible light photographing. An imaging apparatus including: a solid-state imaging element having a plurality of pixels two-dimensionally arrayed on an imaging surface; a light shielding unit that shields an invisible light imaging region of the solid-state imaging element in a space above the imaging surface of the solid-state imaging element; a first optical system that allows light corresponding to visible light contained in external light to be incident on the visible light imaging region of the solid-state imaging element; and a second optical system that allows light corresponding to invisible light contained in external light to be incident on an invisible light imaging region covered by the light shielding unit.

Abstract: The ink jet head module includes: at least one ink jet head that ejects ink; an ink path that supplies ink to the ink jet head; a joint for connecting the ink path and a fitting portion of a printing apparatus main body; a handle which is operated according to attachment and detachment of the ink jet head module to the printing apparatus main body; and a fitting mechanism that inserts and extracts the fitting portion of the printing apparatus main body into and out from the joint in response to movement of the handle.

Abstract: An LDV meter 21 cooperates with an LDV processor 22 to measure travel distances or travel speeds of a transfer belt at a prescribed measuring spot and at intervals with a prescribed rotation angle of one of a set of rollers, on which the transfer belt is stretched, as a set for one or more go-around revolutions of the transfer belt. A roller profile calculator 242 calculates a roller profile data as a set of fractions attributable to an eccentricity of the set of rollers in a set of measurement data. A belt profile calculator 241 removes the set of fractions attributable to the eccentricity from the set of measurement data and calculates a belt profile data representative of irregularities in thickness of the transfer belt based on the set of measurement data after removal of the set of fractions attributable to the eccentricity. In printing, a printing machine 1 controls timing for discharge of ink at an ink head based on the belt profile data and the roller profile data.

Abstract: An EL light-emitting device includes an insulating board, to which an EL light-emitting sheet is fixed on a front surface of the insulating board for allowing penetration, an output terminal disposed on a back surface of the insulating board, which exhibits conductivity and allows penetration, a drive circuit connected to the output terminal, and a conductive member with a pointed portion which fixes the EL light-emitting sheet to the front surface of the insulating board, and conducts the electrode of the EL light-emitting sheet and the output terminal by penetrating the electrode of the EL light-emitting sheet and the output terminal. The force for fixing a sheet EL element is sufficiently strong such that plural sheet EL elements are attached through simple installation work.

Abstract: An EL light-emitting sheet is a sheet body formed by sealing a sheet-shaped EL light-emitting element with a substrate, a back electrode, an insulating layer, a light-emitting layer, and a transparent electrode stacked in this order, wherein an adhesive layer is formed in an outer side of the transparent electrode. If it is stuck by the adhesive layer at a desired position of the back of a sheet-shaped exhibit having a light-transmitting capability at least partially, when the EL light-emitting sheet does not light, only a design of a surface of the exhibit appears (FIG. 3A). When voltage is applied to the EL light-emitting sheet, a light-emitting pattern of the EL light-emitting sheet emerges from the back of the exhibit through the exhibit (FIG. 3B). Therefore, a novel effect is obtained.

Abstract: A metal wiring layer, a plurality of metal plugs, a metal wiring layer, a plurality of metal plugs, a metal wiring layer, a plurality of metal plugs and a metal wiring layer are provided so as to surround a space located in the direction perpendicular to a main surface of a semiconductor substrate of a photoelectric conversion element. These metal parts form a light path. The light path reflects incident light which is entered from outside, thereby preventing the incident light from leaking to other photoelectric conversion elements. Therefore, it is possible to obtain a charge coupled device in which the disadvantage of color dispersion and color blurring between pixels adjacent to each other is suppressed.
