Abstract:
According to one embodiment, an organic electroluminescent device includes a first electrode, a plurality of second electrodes and an organic light-emitting layer. The first electrode includes a first major surface and is optical transparency. The second electrodes extend in a first direction parallel to the first major surface and are separated from each other in a second direction parallel to the first major surface and perpendicular to the first direction. An optical transmittance of the second electrodes is lower than an optical transmittance of the first electrode. A distance along the second direction between a line extending in the first direction and a side surface of each of the second electrodes continuously increases and decreases along the first direction. The side surface is unparallel to the first major surface. The organic light-emitting layer is provided between the first electrode and the second electrodes.

A lighting device including a substrate, and at least three light emitting elements mounted on the substrate, each having an upper light emitting surface in rectangular shape and side light emitting surfaces in rectangular shape. The light emitting elements are positioned to surround a light-gathering region where the light emitting elements are not located, and one of the side light emitting surfaces of each light emitting element is directed to face approximately a central portion of the light-gathering region.
Abstract:
According to one embodiment, an illumination device includes an anode, a metal layer, a cathode, an organic electroluminescent unit, first and second insulating layers, and a plurality of conductive piercing layers. The metal layer has an electrical resistance lower than that of the anode. The cathode is provided between the anode and the metal layer. The organic electroluminescent unit is provided between the anode and the cathode. The first insulating layer is provided between the cathode and the metal layer. The conductive piercing layers pierce the organic electroluminescent unit, the cathode, and the first insulating layer along a direction from the anode toward the metal layer to electrically connect the anode to the metal layer, and are separate entities from the metal layer. The second insulating layer is provided between the organic electroluminescent unit and the conductive piercing layers and between the cathode and the conductive piercing layers.

This fluorescent complex can realize high-intensity fluorescence and a prolonged service life and gives a sharp fluorescence spectrum.
Abstract:
Provided is a voice communication device for carrying out voice communication among a plurality of locations, including: a sound source direction identification block for identifying a direction of a sound source; a voice sender block for sending the collected voice to a different location; a voice receiver block for receiving a voice from a different location; a player block for playing the received voice; a playing information setting block for setting playing information for the voice being played; a speaker volume storage block for acquiring the direction of the sound source for which the playing information is set from the sound source direction identification block and storing the direction of the sound source in association with the playing information; and a voice manipulating block for acquiring the playing information corresponding to the direction of the sound source of the voice and manipulating the voice based on the playing information.
Abstract:
An optical information recording medium includes an optical recording layer onto which information is to be recorded by a laser beam, wherein the optical recording layer includes a dye film containing a specific mono(aza)methine compound and an acid and is directly provided on a surface of a layer that allows transmittance of the laser beam therethrough, the surface being arranged opposite a surface of the layer through which the laser beam enters. The optical recording layer is formed by applying a solution of a mono(aza)methine dye composition containing the acid and the specific mono(aza)methine dye compound by a spin-coating method.

An LED lighting apparatus which comprises an LED chip, and a light-emitting layer which is disposed on a light-emitting side of the LED chip and including an organic fluorescent substance and a matrix containing, as a main component, a fluorine-based or cyanobiphenyl-based liquid crystalline compound exhibiting a nematic phase.
Abstract:
A speech recognition apparatus including a memory for storing with respect to each feature specific to a particular phoneme a name of a process and a procedure of the process which is performed in order to search whether the presence of a feature specific to a certain type of speech is included in a feature vector series, and for storing a table in which the names of the processes in a performed for all the categories of speech to be recognized. The information stored in the memory is used to discriminate between two categories and provides ways for interpreting the results of the process. The recognition processes performed the discrimination is done in accordance with the information stored in the table.
