  • Patent number: 9290692
    Abstract: Disclosed is a polymer light-emitting material for an organic electroluminescent device that displays excellent light-emitting performance and is applicable to a wet process. The polymer light-emitting material for an organic electroluminescent device is obtained by subjecting a thermoplastic resin having an Mw of 2,000-1,000,000 and containing a functional group in a unit constituting the backbone and a metal-containing phosphorescent dopant compound containing a reactive group capable of reacting with the said functional group to a polymer reaction so as to link a phosphorescent dopant moiety derived from the metal-containing phosphorescent dopant compound to the unit constituting the backbone of the thermoplastic resin. The content of the metal derived from the metal containing phosphorescent dopant compound in the said polymer light-emitting material is 0.001-20 wt %.

  • Patent number: 8408611
    Abstract: A vehicle door handle device whereby a door is kept in a locked state by a locking device even if excessive external force is applied to an operation handle. A vehicle door handle device includes a handle base with which an operation handle and a cable are integrated. The handle base has a first portion including a securing part fixed to a door panel, and a second portion including a handle attachment part and a cable fixing part. The handle base further has a weak part between the first portion and the second portion, the weak part being designed to have lower rupture strength than these portions.
