摘要:
Electric charges accumulated in organic EL elements are discharged by applying a voltage for reverse-biasing the organic EL elements from at least one of a plurality of current drive circuits, which is connected to a line scanned at least one line ahead of a line to be scanned currently, to the line associated therewith and by connecting cathode connection lines connected to the current drive circuits other than the current drive circuit to be scanned currently and the line scanned at least one line ahead of the current drive circuit to be scanned currently to a predetermined biasing line. Thus, one or several lines accumulate charges corresponding to the reverse-biasing, so that the total power consumption can be reduced.

An attachment structure for a tape body which supports, on reel hubs, a tape body such as a leader tape, etc. to which a magnetic tape is connected. This attachment structure comprises a tape reel provided with a reel hub which takes cylindrical shape provided at the central portion thereof and a clamp member attached to the reel hub, and a tape body connected to the reel hub in the state where the end portion is supported by the clamp member and wound on the outer circumferential surface of the reel hub. The tape body supported by the reel hub is such that the base end portion side serving as root portion of the drawing side from the reel hub is deformed in the winding direction onto the reel hub following the outer circumferential surface of the reel hub. Deformation of the tape body is carried out by thermal deformation or pressure deformation, or thermal deformation and pressure deformation. The root portion serving as the supporting portion side onto the reel hub of the tape body is deformed following the outer circumferential surface of the reel hub, whereby the tape body is wound in the state closely in contact with the outer circumferential surface of the reel hub.

A writing device including a main body portion having at the front end a writing tip through an ink flow-out control mechanism comprising a valve main body including ink introducing ports, a valve element supported in the valve main body movably forward and backward, and a coil spring for biasing a valve element in the direction of closing a valve seat inserted in the valve main body. The main body portion is formed of an inner pipe and an outer pipe, and a heat shielding space is provided between both pipes. Further, the spring pressure of the coil spring for biasing the valve element in the direction of closing the valve seat inserted in the valve main body is specified to be approximately identical to the writing pressure in writing, and a restriction portion for restricting the opening amount of the valve element against the valve seat is provided at either of the valve element or the valve main body.

An electroluminescent device includes a first optical output part having a light-emitting layer emitting a light ray of a first color, a second optical output part having a light-emitting layer emitting a light ray of a second color, and a third optical output part having a light-emitting layer emitting a light ray of a third color, the colors being different from one another. Each of the optical output parts also has a resonator structure that resonates the light ray emitted from the light-emitting layer. In each optical output part, a resonant peak wavelength indicating a peak value of a transmission spectrum of light transmitted through the resonator structure in a direction perpendicular to a main surface of the light-emitting layer is on a longer or shorter wavelength side of an emission peak wavelength indicating a peak value of an emission spectrum of the light ray emitted by the light-emitting layer.
