摘要:
An epitaxial wafer has a base material made of sapphire-SiC single crystal or the like, a III nitride underfilm including at least Al element epitaxially grown on the base material and a GaN film, preferably having a thickness of 50Å or over, formed on the underfilm. In a fabricating a III nitride films on the epitaxial wafer, the oxidized surface layer of the GaN film is removed through etching process, and subsequently, the III nitride film is formed.

A method of forming a thin, high-quality relaxed SiGe-on-insulator substrate (10) material is provided which first includes forming a SiGe or pure Ge layer on a surface of a first single crystal Si layer (14) which is present atop a barrier layer (12) that is resistant to the diffusion of Ge. Optionally forming a Si cap layer (18) over the SiGe or pure Ge layer (16), and thereafter heating the various layers at a temperature which permits interdiffusion of Ge throughtout the first single crystal Si layer (14), the optional Si cap (18) and the SiGe or pure Ge layer (16) thereby forming a substantially relaxed, single crystal SiGe layer atop the barrier layer (12). Additional SiGe regrowth and/or formation of a strained epi-Si layer may follow the above steps. SiGe-on-insulator substrate materials as well as structures including at least the SiGe-on-insulator substrate material are also disclosed herein.

A decor sheet for use in a decorative laminate includes a sizing agent which is capable of preventing a laminating resin from impregnating fully the sheet such that the capacity of the sheet for the laminating agent is reduced.
摘要:
A laminated material for the manufacture of packing containers with good gas and aroma barrier properties and or parts for such containers, and a method for the manufacture of the laminated material (1). The laminted material (1) comprises a first partial laminate (1) comprising a carrier layer (2) of thermoplastics and a barrier layer (3) of inorganic material of 50-500 Å thickness serving as a gas and aroma barrier, and a second partial laminate (1b) comprising a carrier layer (4) and a barrier layer (5) of inorganic material of 50-500 Å thickness serving as a gas and aroma barrier, these partial laminates being joined to one another by means of an intermediate layer (6) of bonding agent, their respective barrier layers facing inwards towards one another.

A violin and a method for finishing a violin are provided. The violin comprises a plurality of coats of an alcohol based finish having a dye dissolved therein applied to the violin. At least one coat of a spirit based finish and preferably varnish is applied over the alcohol based finish coats. The interior of the violin may also be coated with one or more coats of alcohol or oil based finish.

A violin (10) and a method for finishing a violin are provided. The violin comprises a plurality of coats of white shellac (42-48) applied to the violin and interspersed with at least one color coat. Preferably, the shellac coats comprise a plurality of base coats (42-48) applied directly to the wood (20) of the violin (10), and the color coat (50) is applied over the base coats. The color coat preferably comprises a turpentine base. The top coats (60-66) of white shellac are applied over the color coats. The interior (22) of the violin may also be coated with one or two coats (32, 34) of white shellac.

Lors de l'impression de substrats cellulosiques dans lesquels l'encre d'impression est appliquée sur au moins une surface du substrat cellulosique, une amélioration consiste, avant l'impression sur la surface, à former un dépôt de siloxane et de ses polymères sur la surface où l'on effectue l'impression, le dépôt étant solidaire de la surface.
