    • A laying head for forming an axially moving hot rolled product into a helical series of rings comprises a quill rotatable about an axis, with a tubular body journalled for rotation between axially spaced bearings, and a nose (36)projecting axially and forwardly from its tubular body. A product guide is carried by the quill. The product guide is configured to form the product into a helical series of rings. A guide trough (50) provides a helical extension of the product guide. Major portions of the product guide and the guide trough are carried on a continuous helical support (42) on the nose of the quill. The guide trough is channel shaped, with a continuous bottom defining the rim of the helical support, and with segmented detachable side walls.

    • A light emitting heterostructure and/or device in which the light generating structure is contained within a potential well is provided. The potential well is configured to contain electrons, holes, and/or electron and hole pairs within the light generating structure. A phonon engineering approach can be used in which a band structure of the potential well and/or light generating structure is designed to facilitate the emission of polar optical phonons by electrons entering the light generating structure. To this extent, a difference between an energy at a top of the potential well and an energy of a quantum well in the light generating structure can be resonant with an energy of a polar optical phonon in the light generating structure material. The energy of the quantum well can comprise an energy at the top of the quantum well, an electron ground state energy, and/or the like.
    • 提供了一种发光异质结构和/或其中发光结构被包含在势阱内的器件。 势阱被配置为在发光结构内容纳电子,空穴和/或电子和空穴对。 可以使用声子工程方法,其中将潜在阱和/或光产生结构的带结构设计为便于通过进入发光结构的电子发射极性光学声子。 在这种程度上,在发光结构材料中,势阱的顶部的能量与光产生结构中的量子阱的能量之间的差可以与极性光学声子的能量共振。 量子阱的能量可以包括量子阱顶部的能量,电子基态能量和/或类似物质。
