    摘要: A turbine engine includes a plurality of compressor rotors that include ventilation slots to vent the spaces between adjacent compressor rotors. Each compressor rotor is formed from a flat disk of material having first and second circular faces. A circular ridge of material protrudes outward from the one of the circular faces of the disc adjacent an outer edge of the disc. The ventilation slots are formed in the circular ridge of material. Each ventilation slot is a depression in the circular ridge of material, the depression having a longitudinal axis that extends substantially in a radial direction of the disc.

    摘要: Methods of fabricating SOI wafers are provided including providing a donor wafer and forming a hydrogen ion implantation layer in the donor wafer. A circumference portion of one side of the donor wafer is recessed to form a height difference. The one side of the donor wafer and a handle wafer are bonded to form a bonded wafer. The bonded wafer is heat treated to separate the bonded wafer along the hydrogen ion implantation layer.
