    摘要: A method and apparatus is provided for preparing a substrate for forming electronic devices incorporating III/V compound semiconductors. Elemental halogen gases, hydrogen halide gases, or other halogen or halide gases, are contacted with liquid or solid group III metals to form precursors which are reacted with nitrogen sources to deposit a nitride buffer layer on the substrate. The buffer layer, which may be a transition layer, may incorporate more than one group III metal, and may be deposited with amorphous or crystalline morphology. An amorphous layer may be partially or fully recrystallized by thermal treatment. Instead of a layer, a plurality of discrete nucleation sites may be formed, whose size, density, and distribution may be controlled. The nitrogen source may include reactive nitrogen compounds as well as active nitrogen from a remote plasma source. The composition of the buffer or transition layer may also vary with depth according to a desired profile.

    摘要: This invention relates to a printing apparatus and a conveyance control method capable of simultaneously operating plural encoder sensors and executing more accurate printing medium conveyance control. A first encoder sensor provided adjacent to a first conveyance roller detects the conveyance amount of a printing medium by the first conveyance roller provided in the conveyance path of the printing medium. A second encoder sensor provided adjacent to a second conveyance roller detects the conveyance amount of the printing medium by the second conveyance roller provided in the conveyance path of the printing medium at the downstream side from the first conveyance roller in the conveyance direction of the printing medium. For example, conveyance of the printing medium is controlled on the basis of the output signals from the first and second encoder sensors when a tail end of the printing medium is located adjacent to the first conveyance roller.

    摘要: A recording apparatus for forming images using a recording head includes a feeding roller, a conveying roller, a conveyance control unit, and a recording control unit. The conveyance control unit performs a conveying operation a number of times after the trailing end of a sheet reaches a predetermined position defined between the feeding roller and the conveying roller such that the trailing end of the sheet is disposed in a predetermined range upstream of the conveying roller in a sheet conveying direction after the conveying operations. At least one of the conveying operations performed a number of times is performed based on a distance from the position of the trailing end of the sheet to the position of the conveying roller.
