Title: Process for plasma enhanced anneal of titanium nitride
Inventor: HILLMAN JOSEPH T
IPC: H01L21/321
Filed: 1996-05-28
Abstract: A titanium nitride film is annealed at a temperature less than 500 ~C by subjecting said titanium nitride film to an RF created plasma generated from a nitrogen-containing gas in a rotating susceptor reactor. The formed film is comparable to a thin film annealed at significantly higher temperatures, making this process useful for integrated circuits containing aluminum elements.

Patent CA-2230568-A1 (CA)
Inventor: MCLEOD GAVIN THOMAS
IPC: E21B23/02
Filed: 1996-08-22
Abstract: A retraction system is described for allowing disengagement of retrieval latch dogs (114) of a down hole running tool (14) from a bit locking sleeve (18). The locking sleeve (18) is slidably retained within a drive sub (12) and includes a pair of slots (66) which are engaged by the retrieval latch dogs (114) when the tool (14) is used to retrieve bit segments (16) from the drive sub (12). The retraction system includes a sleeve (76) which is slidably mounted on a main body (74) of the tool (14) and spring (174) which is biased to push the sleeve (76) over the retrieval latch dogs (114). The sleeve (76) has a pair of diametrically opposed slots (235) through which the retrieval latch dogs can extend for contacting the inner surface (28) of the drive sub (12). The retraction system also includes a length (44) of the inner surface of the drive sub (12) which is made of progressively reducing diameter in the direction of retraction of the tool (14) from the drive sub (12). The upper end of each slot (235) is provided with a bevel (236) for directing the retrieval latch dogs (114) in the inward direction. To withdraw the tool (14) from the drive sub (12), the retrieval latch dogs (114) are disengaged from the bit locking sleeve (18) by the combined action of the shape of surface portion (44) which acts to push the retrieval latch dogs (114) inwardly, together with the force of spring (174) and the bevelled surfaces (236) which act to push the sleeve (74) over the retrieval latch dogs (114) thereby disengaging it from the bit locking sleeve (18).

Title: Optically resonant structure
Inventor: ADAMS MICHAEL JOHN
IPC: H02G15/013
Filed: 1996-09-26
Abstract: A vertical cavity surface emitting laser comprises a resonant cavity (2) formed between a distributed Bragg reflector formed of semiconductor material (3) and an overlying distributed Bragg reflector (4) formed of dielectric material. The resonant cavity contains a layer (8) of laser active material sandwiched between spacer layers (9, 10), and a blocking layer (16, 19) which confines an energising electric current to flow through the cavity between a metallic contact layer (13) on the underside of the Bragg reflector (4) and a contact (17). In order to support a preselected resonant mode, a series of concentric rings (18) is formed in the blocking layer (16, 19), surrounding the resonant cavity (2) so as to provide a Bragg structure which reflects light from the cavity with a phase characteristic that supports the preselected transverse resonant mode.

Abstract: On Fork Lift (100), Load Cell Assemblies (40a and 40b) are affixed to Fork Arms (32a and 32b) and are capable of weighing any object lifted by the Fork Arm Lift Assembly (30). Continuous weight information is transmitted from the Assemblies (40a and 40b) to Fork Lift Computer (52) via wires and IR  Transmitter (44) and Receiver (48). Changes in weight information are interpreted as load engagement and disengagement by Computer (52), which then responds by receiving the current relative vertical height Fork Arm Lift Assembly (30) from Ultrasonic Distance Measuring Unit (56). The Computer (52) then transmits, via Telescoping Antenna (70), a uniquely encoded signal with both weight and height information to Stationary Elevated Locating Modules such as 74a and 74b, which have been strategically placed throughout the operating range of Fork Lift (100). This signal is then transmitted to Unit Tracking Computer System (80) by Locating Modules such as 74a and 74b.  Computer (84) is capable of storing this information to track the exact location and weight of the moved objects.

Title: Apparatus for drilling lateral drainholes from a wellbore
Inventor: CHERRY DONALD E
IPC: E21B17/20
Filed: 1998-11-20
Abstract: Apparatus for drilling lateral drainholes from a well casing comprises a flexible shaft having a bit at the lower end; the shaft extending through a shaft guide conduit anchored within the casing adjacent an oil-bearing formation. The "L" shaped guide conduit re-directs the shaft from an path parallel to the casing, through an elbow, to a path substantially perpendicular to the casing. The flexible shaft is formed of a helically wound outer coil spring and one or more helically wound and smaller inner coil springs residing concentrically therein. Each coil spring is closely fitted within the other. Each coil spring is wound opposite in direction to that of the next adjacent coil spring so as to interfere when under torsion. Bushings are located within the elbow for causing the shaft to flex and turn while permitting rotation and axial movement therethrough. A motor imparts torque into the top of the shaft, preferably through an intermediate driveshaft. The shaft is movable up and down within the casing. Accordingly, when the motor is rotating the bit, and the shaft is lowered, the shaft guide conduit supports the shaft, guides it through the elbow and directs the bit against the casing for cutting through the casing and then into the formation.
