摘要:
Provided is a manufacturing method by which each functional layer of various types of organic electronic elements can be uniformly formed by wet process. Specifically, a method for manufacturing an organic electronic element which uniformly emits light with high emission efficiency is provided. The method for manufacturing the organic electronic element includes a step of forming a functional layer by laminating at least an organic layer (A) and an organic layer (B) in this order on a substrate. After forming at least the organic layer (A), the organic layer (B) is applied and formed on the organic layer (A) by using a fluorine-containing solvent.

An organic electroluminescent element having at least an anode, a cathode, and a light-emitting layer held between the anode and the cathode on a substrate and emitting white light. The light-emitting layer consists of three or less layers, the light-emitting material contained entirely in the light-emitting layer consists of at least four kinds of light-emitting material having different emission maximum wavelengths (λmax). The four kinds of light emitting material have emission colors of blue, green, yellow red and red, and since one or more layers out of the three or less layers of the light-emitting layer contain two or more kinds of light-emitting material simultaneously, there is obtained an organic electroluminescent element excellent in color rendering and exhibiting high power efficiency in which variation in emission color is small even if current density varies.
摘要:
A support (611) that is substantially cylindrical so as to be received by a disk hole (1NA) and has a positioning portion (612) on a circumference adjacent to a first axial end is provided with a concave portion (613) of which both ends open to the circumference along a radial direction. A first engaging portion (614) protrudes from around the circumference at which a first axial end of the concave portion opens substantially opposes to the positioning portion with a gap equal to or more than a thickness of an optical disk (1N). A moving member (615) is disposed in the concave portion in a manner movable along a radial direction of the support. A second engaging portion (616) protrudes on an end of the moving member at a position corresponding to a second axial end of the concave portion.

An object is to provide a connector with which a cable assembly with suppressed generation of a noise during high-speed signal transmission can be formed, and a cable assembly using the connector. The connector 10 of the present invention is characterized as follows. Specifically, the connector 10 includes: a substrate 11; multiple signal terminals 31, 32 provided parallel to each other on one surface of the substrate 11; and a ground layer 41 provided on another surface of the substrate 11. Each of the signal terminals 31, 32 and the ground layer 41 are disposed in such a manner that at least a portion of the ground layer 41 and at least a portion of each of the signal terminals 31, 32 are superposed on each other with the substrate 11 therebetween. Multiple holes 43 are formed in the portion of the ground layer 41 superposed on each of the signal terminals 31, 32. A largest diameter of each of the holes 43 is smaller than a distance L between the centers of the signal terminals adjacent to each other.

This invention provides a multicolor phosphorescent organic electroluminescent element having an excellent electric power efficiency, a prolonged service life, an excellent storage stability, and an excellent stability of chromaticity against drive current, and a lighting system using the multicolor phosphorescent organic electroluminescent element. The multicolor phosphorescent organic electroluminescent element contains a plurality of phosphorescent dopants different from each other in luminescence wavelength and particularly exhibits white luminescence. Specifically, the multicolor phosphorescent organic electroluminescent element contains two or more phosphorescent dopants different from each other in luminescence wavelength and comprises two or more luminescent layers, the luminescent dopant being a phosphorescent dopant. The multicolor phosphorescent organic electroluminescent element is characterized in that at least one layer formed of luminescent layer A containing two or more phosphorescent dopants different from each other in luminescence wavelength in the same layer is provided, the content of the luminescent dopant having the highest concentration used in the luminescent layer A is not less than 4% by mass and not more than 20% by mass, and luminescent layer B having a maximum luminescence wavelength of not more than 480 nm is provided at a position near the cathode side as compared with the luminescent layer A.
摘要:
A gas chamber (G) and a liquid chamber (R) are separated by a free piston (2) in a cylinder (1) of a hydraulic damper. The free piston (2) comprises a hollow main body (3), a metal bellows (4) which elongates and contracts according to a pressure balance between the gas chamber (G) and liquid chamber (R), and a stopper (8) fixed to the main body (3) for preventing the metal bellows (4) from elongating beyond a predetermined length. By compensating for variation in the capacity of the liquid chamber (R) caused by a displacement of the piston (10) in the cylinder (1) by elongation or contraction of the metal bellows (4), the damping characteristic of the damper is prevented from becoming unstable due to a frictional force acting on the free piston (2). The stopper (8) prevents excessive stress from being exerted on the metal bellows (4).

The mounting portion (4) has, on the top face, a flat face portion perpendicular to an axis of the shock absorber body. The spring seat (3) includes a cylindrical seat body (15), a seat portion (16) projected from an outer side of the cylindrical seat body (15) and an engagement portion (18) projected from an inner side of the cylindrical seat body (15). Further a travel stop device is disposed between the spring seat (3) and the mounting portion (4), thereby to stop relative rotation and upward/downward-direction travel thereof.
