Inventor: HARRALL SIMON JOHN
IPC: E21B37/00
Filed: 2005-06-30
Abstract: A method for cleaning and/or altering an inside surface and shape of a tubular is disclosed. The method includes placing a surface finishing tool in the tubular, energizing the surface finishing tool, and causing extendable assemblies therein to extend radially to contact an inside diameter of the tubular. Moving the surface finishing tool axially and/or rotationally while the extended members are in contact with the inside diameter of the tubular cleans debris from the inside surface of the tubular. In another aspect of the invention, the tool burnishes the inside diameter of the tubular, thereby altering the surface characteristics and rounding the tubular.

Patent CA-2532959-A1 (CA)
Title: Failure analysis methods and systems
Inventor: ANDERSON GREGORY B
IPC: H01L21/46
Filed: 2004-07-15
Abstract: A method and system for exposing the delicate structures of a device encapsulated in a mold compound such as an integrated circuit (IC). A laser is used to ablate the mold compound and thus remove it, exposing the underlying structure. The laser beam can be steered in a desired raster pattern onto the surface of the device or the device can be moved in the desired pattern relative to the laser beam. Spectral analysis can be performed on the laser plume emitted by the ablation process in order to determine the composition of the ablated material. Thus, in addition to exposing defects in the underlying structure, the system can also be used to analyze the encapsulating material in order to determine whether it contained any defects or anomalies. A system for precisely cutting a circuit board or an IC in a user-selected pattern is also described. The system directs a laser along a path that a user can specify using a graphical interface.

Title: Heat treatable coated article with dual layer undercoat
Inventor: STACHOWIAK GRZEGORZ
IPC: B32B9/00
Filed: 2004-09-16
Abstract: In certain example embodiments, a multi-layer undercoat may include a layer of or including tin oxide on the glass surface and a layer of silicon nitride thereover. Tin oxide is advantageous in that it is relatively durable, and is a low stress material with excellent adhesion to glass. Moreover, the sputtering rate for tin oxide is several times higher than that of silicon nitride. Thus, problems of high cost (due to slow deposition rate) and durability (due to high compressive stress) can be overcome through the use of tin oxide as a bottom portion of the dual layer overcoat. The coated article may or may not be heat treated in different embodiments of the invention.

Filed: 2004-11-24
Abstract: It is intended to provide a novel meiosis-specific centromeric protein Sgo1 (shugoshin) originating in a fission yeast Schizosaccharomyces pombe as a factor ensuring the retention of unidirection and adhesion in sister centromeres in the first meiotic division synergistically with cohesin, its homolog or paralog having an activity of regulating chromosomal distribution, and DNA encoding the same. To clarify a protein protecting Rec8 in the latter stage of division, screening is made of a gene which regulates mitotic division development and inhibits the separation of sister chromatids in the latter stage of division, when expressed together with Rec8, from among fission yeast genes. As the result of this approach, a meiosis-specific protein Sgo1 which protects (shugo) centrometic Rec8 from degradation in the latter stage of first division is found out. Moreover, an Sgo1 homolog of a budding yeast and a mitotic division paralog Sgo2 of a fission yeast are found out.
