Patent CA-2140403-A1 (CA)
Inventor: KING TSU-JAE
IPC: H01L21/336
Filed: 1995-01-17
Abstract: In the channel layer of a thin film transistor (TFT), a channel and its drain meet at a transition within a transition region. The channel extends in a first, or horizontal, dimension away from the drain and extends in a second, or vertical, dimension from a side away from the gate to a side toward the gate. The charge carrier densities in the transition region vary in the second dimension in a way that reduces leakage current, because the position of the maximum electric field is moved away from the gate and its magnitude is reduced. Variation of densities in the second dimension can be produced by high angle implantation of a dopant and a counterdopant, providing a transition region between the drain and the channel underneath the gate. Variation of densities in the second dimension can also be produced with non-angled implantation by a process in which a sidewall spacer offsets the drain, providing a transition region that is between the drain and the channel and that can be doped independently of the drain. In a symmetric TFT in which either channel lead can function as a drain, charge carrier densities can vary in the second dimension at the transitions between each channel lead and the channel.

Title: Mercury recovery process
Inventor: ORAM PETER GLEN
IPC: B09C1/02
Filed: 1995-06-05
Abstract: A process for the recovery of heavy metals, and in particular, mercury from a heavy metal-contaminated soil, or the recovery of mercury from a mercury-contaminated material, wherein the particles containing the heavy metal or mercury are separated from soil or mercury-contaminated material by a hydraulic mineral separator. The process may additionally comprise pre-classification of the soil particles to form a sample having essentially constant soil particle size prior to separation in the mineral separator. The process provides a ready method for removal of mercury from mercury-contaminated materials or heavy metals from heavy metal contaminated soils which process can allow recovery of the mercury or heavy metal for re-use. Alternatively, the process provides a smaller volume of mercury- or heavy metal- contaminated soil or material to be treated.

Inventor: GLOCKLER HERRMANN J
IPC: A61F9/007
Filed: 1995-12-18
Abstract: A method and apparatus for providing sequential temporal and spatial integration of a collimated non-symmetrical excimer laser beam to optimize the temporal and spatial characteristics of the beam. The temporal integrator comprises a pair of cylindrical lenses spaced along the beam axis by a distance substantially equal to the sum of the focal length of both lenses, and a motor mechanism for rotating the two spaced cylindrical lenses about the beam axis. The spatial beam integrator includes a plurality of prisms distributed about a hollow center, the outlet face of each prism being angled with respect to the body axis of the spatial beam integrator so that portions of the laser beam passing through a given prism are refracted towards the center upon emergence from the outlet face. The spatial beam integrator is preferably rotated about the beam axis at twice the rotation rate of the cylindrical lenses so that the rotated beam emerging from the temporal beam integrator is stationary with respect to the spatial beam integrator.  Alternatively, the spatial beam integrator may be rotated at the same rate as the cylindrical lenses, or may be maintained stationary, i.e., not rotated at all.

Title: Poliovirus specific primers and method of detection utilizing the same
Inventor: KILPATRICK DAVID R
IPC: C12N15/09
Filed: 1994-07-11
Abstract: The ability to rapidly detect wild polioviruses in clinical specimens is a major concern for the worldwide eradication of polioviruses. Provided is a method of detecting poliviruses of all three serotypes from viral isolates of clinical specimens using a pair of degenerate PCR primers. This primer set, which uses deoxyinosine residues to compensate for third position mismatches at specific positions, recognizes nucleotide sequences near the receptor binding site of polioviruses. These sequences are unique to polioviruses and are absolutely conserved at the amino acid level. As a result, these PCR primers do not recognize nonpoliovirus enteroviruses. All poliovirus serotypes (40 poliovaccine related genotypes and 120 wild poliovirus genotypes from around the world) tested positive. All 14 prototype strains of nonpoliovirus enteroviruses tested negative. Also provided is a series of degenerate PCR primers that differentiates between the three wild poliovirus serotypes and a method of detecting the presence of the three serotypes utilizing a nucleic acid amplification technique.
