Title: Strip casting
Inventor: NIKOLOVSKI NIKOLCO
IPC: B22D11/128
Filed: 2001-06-14
Granted: 2005-04-11
Abstract: Twin roll caster for casting thin steel strip comprises chilled casting rolls 16 mounted on roll supports 104. One of the rolls is fixed and the other is moveable laterally and biased toward the other roll by biasing units 119 acting on the moveable roll supports 104. A casting pool of molten steel is supported on the rolls 16 and the rolls are rotated to produce a solidified steel strip delivered downwardly from the nip between the rolls. A substantially constant gap is maintained between rolls 16 such that unsolidified molten metal passes through the nip between the solidified shells of the forming strip and solidifies below the nip. The biasing units 119 are effective to apply substantially constant and low biasing forces to the biased roll. The biasing forces may be between the same and slightly more than the force required to balance the hydrostatic pressure of the casting pool and to overcome the mechanical friction involved in moving the biased roll. Controlling these casting roll separation forces enables gauge variation in the strip to be reduced.

Title: Assembly method of flat panel display
Inventor: LI CHIEN-HSING
IPC: H05K13/00
Filed: 2001-07-16
Granted: 2005-04-01
Abstract: An assembly method of a flat panel display is disclosed. The flat panel display comprises a face plate and a bottom plate and the assembly method is employed to bind the face plate and the bottom plate together. The bottom plate comprises at least a suction hole which is connected to an air suction unit. The assembly method comprises following steps. Firstly, an elastic material is placed to the area close to the edge of the bottom plate, surrounding the bottom plate. Then, an adhesive is formed on the bottom plate. After the face plate and the bottom plate are aligned, the face plate and the bottom plate are adhered. Meanwhile, a closed space is formed among the bottom plate, the face plate and the elastic material. An air suction unit is used to withdraw air in the closed space to generate a pressure difference between the closed space and the outside ambience. The pressure difference is used to create a suction force to facilitate adhesion of the face plate and the bottom plate. The method can not only decrease probability of panel breakage but also reduce air bubble generation so that the degree of bonding of the adhesive is increased and heat is evenly dissipated.

Title: Self teaching robot
Inventor: HINE ROGER G
IPC: H01L21/677
Filed: 2001-12-03
Granted: 2002-11-01
Abstract: A robot calibration system for calibration of a workpiece handling robot relative to a station. The workpiece handling robot includes a sensor mounted on an end effector. The robot calibration system also includes a target, which in coordination with the sensor, allows a control system to determine a center of the target. The target is a wafer in the shape of a disk. A pattern is on at least one side of the workpiece, preferably on a bottom side of the target The pattern comprises alternating black and white areas. The workpiece handling robot is placed in front of the station which includes a cassette mounted thereon. The cassette has a support surface which supports the target. Once the z-height of the end effector is established with the end effector being in close proximity to a lowermost support surface of the cassette, the end effector proceeds to move in a search pattern searching the pattern for transition points from black to white areas. The control system stores these transition points and uses the transition points in an algorithmic equation to determine the center of the target. Once the center of the target has been identified, the control system knows the spacial relation between the robot and the station, and in particular the position of the workpieces at the station. The station may thereafter be loaded with workpicces and processed accordingly.

Title: The design method of the microwave concave lens antenna for converting omnidirectional radiation pattern into multi-beam with different beamwidth
Inventor: CHUNG DAU-CHYRH
IPC: H01Q15/00
Filed: 2002-03-07
Granted: 2004-04-11
Abstract: The antenna radiation pattern for traditional wire array antenna will have omni directional radiation pattern due to the cylindrical wave. In this proposed invention, a plane wave can be transformed from the cylindrical wave to generate a directional antenna radiation pattern. For traditional BTS (base transceiver station), the beamwidth for each antenna array pattern is about 65o. This wide angular beamwidth will not only cause the serious interferences and fading problems, but also limit the spectrum efficiency. For special BTS application, different directivity antenna radiation patterns are required. Also in this proposed patent, the designed microwave lens can generate multiple antenna beam patterns with different directivities for special BTS application.
