  • Patent number: 9012940
    Abstract: An optoelectronic semiconductor body (1) having an active semiconductor layer sequence (10) and a reflective layer system (20) is described. The reflective layer system (20) comprises a first radiation-permeable layer (21), which adjoins the semiconductor layer sequence (10), and a metal layer (23) on the side of the first radiation-permeable layer (21) facing away from the semiconductor layer sequence (10). The first radiation-permeable layer (21) contains a first dielectric material. Between the first radiation-permeable layer (21) and the metal layer (23) there is disposed a second radiation-permeable layer (22) which contains an adhesion-improving material. The metal layer (23) is applied directly to the adhesion-improving material. The adhesion-improving material differs from the first dielectric material and is selected such that the adhesion of the metal layer (23) is improved in comparison with the adhesion on the first dielectric material.

  • Patent number: 8723199
    Abstract: A radiation-emitting body comprising a layer sequence, having an active layer (10) for generating electromagnetic radiation, having a reflection layer (50), which reflects the generated radiation, and having at least one intermediate layer (40) arranged between the active layer (10) and the reflection layer (50). In this case, the active layer (10) has a roughening on an interface (15) directed toward the reflection layer (50), and the reflection layer (50) is substantially planar at an interface (45) directed toward the active layer (10). Also disclosed is a method for producing a radiation-emitting body, which involves forming a layer sequence on a substrate having an active layer (10) for generating electromagnetic radiation. In this case, the method comprises roughening an interface (15) on the active layer (10), and forming at least one intermediate layer (40) and a reflection layer (50).

  • Publication number: 20070245694
    Abstract: The present invention is directed to methods and apparatuses for applying a fluid to the inside of a product packaging material and/or to the outside of a product during packaging of the product. The present invention incorporates a sprayer system into the design of a packer tube and allows the inside surface of the product packaging material and/or the outside surface of the product to be contained within the packaging material to be coated with a fluid. The fluid is applied simultaneously with the packaging of the product. As such, separate steps for applying the fluid and also for packaging the product are not required. In one embodiment, methods and apparatuses for applying a food colorant to the inside of a food packaging material and/or to the outside of a food product during packaging of the food product are provided.

  • Publication number: 20070134382
    Abstract: Provided are high temperature, venting food preparation bags used to package food products for storage, transportation, and preparation and methods for making and using the same. High temperature, venting food preparation bags are composed of a sealed end, an open end, at least one side wall composed of a first thermoplastic film having a vent, and a vent seal composed of a second thermoplastic film. The vent seal is fused to the sidewall via a non-adhesive seal thereby closing the vents. At elevated temperatures, the vent seal at least partially detaches from the side wall thereby opening the vents. Opening of the at least one vent is not dependent upon the accumulation of internal fluid or gaseous pressure, and is compatible with vacuum packaging techniques. Vented cooking techniques are provided that permit browning and crisping of beef and poultry without manipulating the food preparation bag during cooking.
