20090278119 | OLED DISPLAY WITH EXTENDED LIFETIME - The present invention relates to an organic light-emitting diode which has a light-emitting layer C which comprises at least one hole-conducting material CA and at least one phosphorescence emitter CB, to mixtures comprising at least one carbene complex in combination with at least one hole-conducting material or in combination with at least one phosphorescence emitter, and to the use of mixtures comprising at least one hole-conducting material and at least one phosphorescence emitter as a light-emitting layer in OLEDs for prolonging the lifetime of the light-emitting layer. The inventive organic light-emitting diode may have, in at least one of the layers of the organic light emitting diode, preferably in the hole-blocking layer and/or the electron-blocking layer and/or the light-emitting layer C, in addition to the hole-conducting material CA and the emitter CB, at least one compound selected from disilylcarbazoles, disilyldibenzofurans, disilyldibenzothiophenes, disilyldibenzophospholes, disilyldibenzothiophene S-oxides and disilyldibenzothiophene S,S-dioxides. | 11-12-2009 |

20140366833 | Connecting Rod with Bearing-less Large End - A connecting rod of an internal combustion engine, that includes a large bore, and an interior bore surface. The current art uses soft metal bearing surfaces to reduce wear, and friction between the connecting rod inner diameter and the crankshaft journal surface. The soft metal bearing surface is a separate component of the engine. In this invention the large bore end interior diameter is coated with a hard material to reduce, or eliminate wear. The hard material is a metal or metal alloy applied to the inner diameter by a thermal spray method. A relatively soft polymer material can also be applied to the interior diameter surface of the con-rod bore. The relatively softer polymer acts as a first and sometimes a consumable layer, and applied over the thermal sprayed hard layer. The polymer layer is often used in conjunction with the sprayed metal layer. The polymer coating may be worn off the inner diameter surface; this delay in surface to surface contact to the sprayed metal layer has beneficial effects on the sprayed metal layer. The delay of surface to surface contact will usually result in a longer service life of the sprayed metal coating. | 12-18-2014 |

20130209032 | Free Optical Beam Fiber-to-Fiber Coupling Systems - A fiber-to-fiber coupling system includes: multiple optical input fibers, each optical input fiber having an exit-face on a light-exit side of the optical input fiber, in which the light-exit-sides are disposed around a central axis, and in which an optical axis extending through the light-exit side is tilted toward the central axis; an optical output fiber having an entry-face for receiving light; and an optical input-coupling device arranged to couple a light beam exiting from the end-face of each optical input fiber into the entry-face of the output fiber. The optical input-coupling device comprises, for each light beam exiting the exit surfaces of the optical input fibers, a single corresponding lens to transmit the light beam or a single corresponding ellipsoidal mirror to reflect the light beam. | 08-15-2013 |
