  • Publication number: 20090322210
    Abstract: The present invention is directed to an organic electroluminescent element of good display characteristic without being contaminated with air in the case that a sealing substrate is affixed to an entire surface of the effective pixels of an organic electroluminescent element substrate by an adhesive. An organic electroluminescent element substrate includes a substrate, pixel electrodes formed over the substrate, an organic luminescence medium layer including an organic luminescent layer on the pixel electrodes which emits different color light, and opposed electrodes wherein the organic luminescence medium layer is between the pixel electrodes and the opposed electrodes, wherein the organic electroluminescent element substrate has partition wall(s), and wherein difference of height in effective pixels of the organic electroluminescent element substrate is less than 1 ?m.

  • Patent number: 5135712
    Abstract: A process for producing an injection-molded sintered product by powder metallurgy includes injection molding a kneaded product including a magnetic powder and a binder, releasing the molded product from the metal mold, and sintering the molding after debindering, wherein the molding is taken out from the metal mold using an electromagnet which exerts an adsorptive force to the molding. The process simplifies the release of the injection-molded products from metal molds and the transfer of the molding to the debindering process. The process is suitable for mass production, gives high yield, and has a wide applicability to products regardless of their shape.
