Patent CA-2345786-A1 (CA)
Inventor: LITWIN ANDREJ
IPC: H01L23/15
Filed: 1999-09-23
Abstract: The present invention relates to a method and device for interconnecting radio frequency power SiC field effect tansistors. To improve the parasitic source inductance, advantage is taken of the small size of the transisitors, wherein the bonding pads are placed on both sides of the die in such a way that most of the source bonding wires (6) go perpendicularly to the gate and drain bonding wires (7, 8). Multiple bonding wires can be connected to the source bonding pads, reducing the source inductance. An additional advantage comes from such arrangement by reducing the mutual inductance between source/gate and between source/drain due to the orthogonal wire placement.

Title: Sol-gel process using porous mold
Inventor: KIRKBIR FIKRET
IPC: B01J3/00
Filed: 1999-10-07
Abstract: A sol-gel process for producing dry porous metal oxide monoliths, e.g., silica glass monoliths, in which the successive process steps of gelling, aging and drying all occur within a mold formed of a porous non-organic-polymer material, e.g., graphite. The mold is inert to the gel solution and has sufficient strength to withstand the temperatures and pressures encountered during the process. The mold and gel thereby can remain within a sealed autoclave during these process steps, and mechanical handling of the mold and the gel are minimized. This substantially enhances the process' efficiency.  Alternatively, the mold can have a non-porous inner skin to enhance ease of cleaning of the mold, and of removal of the gel.

Inventor: KAHN JON B
IPC: E21B47/022
Filed: 2001-08-29
Abstract: This invention provides a measurement-while-drilling (MWD) downhole assembly for use in drilling boreholes which utilizes gyroscopes, magnetometers and accelerometers for determining the borehole inclination and azimuth during the drilling of the borehole. The downhole assembly includes at least one gyroscope that is rotatably mounted in a tool housing to provide signals relating to the earth's rotation. A device in the tool can rotate the gyroscope and other sensors on the tool to one of a plurality of preselected positions and optionally lock the sensors. A processor in the tool combines measurements from the sensors taken at a plurality of positions at the same depth to determine the systematic bias in the sensors before further processing. Accelerometers in the MWD tool provide gravity measurements from which the toolface and inclination are determined. The unbiased gyroscopic measurements are used in conjunction with the tool face and inclination measurements to determine the azimuth and tool face with respect to true north. Additionally, when measurements are made with magnetic, accelerometer and gyroscopic measurements along three different axes, the unbiased measurements may be combined to provide an improved determination of the tool orientation. Using the locking mechanism, measurements may be made with the sensor housing locked in place during continuing drilling operations. When used with a drilling liner system, the sensor assembly may be retrieved using a wireline. With the present invention, a secondary borehole for secondary recovery operations may be drilled with accuracy in proximity to a producing borehole.
