Abstract: SiC is an extremely stable substance, so that it is difficult to control the surface condition of SiC for one suitable for crystal growth by means of common Group III nitride crystal growing apparatus. Thus, the following treatment is performed. The surface of SiC substrate (1) is formed into a step-terrace structure by heat treatment in an atmosphere of HCl gas. The surface of SiC substrate (1) is sequentially subjected to royal water, hydrochloric acid and hydrofluoric acid treatments so as to etch a silicon oxide film slightly formed on the surface of SiC substrate (1), thereby producing SiC cleaned surface (3) at the substrate surface. The SiC substrate (1) is secured in a high vacuum apparatus, and ultrahigh vacuum condition (e.g., 10- 6 to 10-8 Pa) is held inside the apparatus. In ultrahigh vacuum condition, for example, a process comprising irradiating Ga atom beams (5) at time t1 at 800°C or below and conducting heat treatment at 800°C or above is repeated at least once. The temperature is set for AlN film growing temperature, and in ultrahigh vacuum condition the surface (3) of SiC substrate is irradiated in advance with Al atom (8a). Thereafter, N atom (8b) is fed thereto.

Title: Content notification and delivery
Inventor: ODDO ANTHONY SCOTT
IPC: H04N5/445
Filed: 2004-04-02
Abstract: Disclosed are methods and systems for displaying content recommendations to a television viewer. In one aspect of the invention, when the user changes channel, the system displays contact recommendations to the user before going to the next channel. The recommendations are based on user profiles and/or aggregated multi-user content. In a further aspect, the user can decide on one of the recommendations (or answer a yes/no query) to migrate to the corresponding content.
Patent KR-20060003358-A (KR)
Title: Center-located cutter teeth on shrouded turbine blades
Inventor: URBAN JOHN PAUL
IPC: F01D5/20
Filed: 2004-04-15
Abstract: The shroud (12) includes a seal (24) extending continuously between leading and trailing edges of the shroud at the tip of the airfoil. A cutter tooth (32) is provided substantially medially of the shroud and in substantial radial alignment with a line through the center of mass of the airfoil (12). In this manner, any moment arm generated by movement of the shroud is eliminated or minimized to reduce the stresses in the fillet region between the shroud and the airfoil tip and hence increase the creep life of the bucket.
