Abstract:
An imaging device includes a photoelectric conversion element which photoelectrically converts incident light and generates a charge, accumulates and amplifies the charge, and outputs a photocurrent, wherein a level of an output signal when a charge which is accumulated in the photoelectric conversion element is outputted over a saturated amount of accumulable charge includes a level of an output signal of a charge of a photocurrent of DC component which is generated in the photoelectric conversion element and outputted during a readout time when the charge which is accumulated in the photoelectric conversion element is outputted.
Abstract:
A light-emitting element includes a reflective electrode, a light-transmitting electrode disposed opposite the reflective electrode, a light-emitting layer emitting blue light disposed between the reflective electrode and the light-transmitting electrode, and a functional layer disposed between the reflective electrode and the light-emitting layer. The optical thickness of the functional layer is no less than 428.9 nm and no more than 449.3 nm.
Abstract:
To increase light-extraction efficiency and simplify manufacturing process. An organic EL panel includes: first electrode reflecting incident light; second electrode transmitting incident light therethrough; organic light-emitting layer emitting light of corresponding color among R, G, and B colors; first functional layer including charge injection/transport layer and at least one other layer, and disposed between the first electrode and the light-emitting layer; and second functional layer disposed between the second electrode and the light-emitting layer. The charge injection/transport layers of R, G, and B colors differ in film thickness, the at least one other layers of R, G, and B colors are equal in film thickness to one another, the second functional layers of R, G, and B colors are equal in film thickness to one another, and the light-emitting layers of R and G colors are equal in film thickness, and differ in film thickness from the light-emitting layer of B color.
Abstract:
An organic EL panel includes first electrode, second electrode; organic light-emitting layer of each of RGB colors, and functional layer disposed between the first electrode and the light-emitting layer. The functional layers of RGB colors have the same film thickness. Film thickness of each of the functional layers of RG colors corresponds to a first local maximum of light-extraction efficiency of light before passing through a color filter, and film thickness of the functional layer of B color corresponds to a value of light-extraction efficiency smaller than a first local maximum of light-extraction efficiency of light before passing through a color filter. The light-emitting layers of RGB colors differ in film thickness, such that the functional layers of RGB colors have the film thickness. Accordingly, the light of each of RGB colors emitted externally after passing through the color filter exhibits a local maximum of light-extraction efficiency.

Abstract:
An optical communication system includes first and second optical terminal apparatuses, first and second optical repeating installations, a working transmission line coupling the first and second optical terminal apparatuses via the first optical repeating installation, and a protection transmission line coupling the first and second optical terminal apparatuses via the second optical repeating installation. Each of the first and second optical terminal apparatuses and the first and second optical repeating installations include a mechanism for transmitting an overhead signal including an identifier to the working transmission line and the protection transmission line by multiplexing the overhead signal with main signals when operating as a transmitting apparatus or installation, where the identifier identifies an apparatus or installation to be supervised, a mechanism for transferring the overhead signal as it is when not identified by the identifier, a mechanism for returning a response signal to one of the working transmission line and the protection transmission line from which the overhead signal is received when identified by the identifier, and a mechanism for cutting the apparatus or installation from one of the working transmission line and the protection transmission line so as not to transfer the overhead signal thereto, and passing through the overhead signal in other apparatuses and/or installations.
