The present invention provides, in one embodiment, an annular turbine seal for disposition in a turbine between a rotatable component having an axis of rotation and a turbine housing about the same axis of rotation. The turbine seal has a plurality of arcuate seal carrier segments that have an abradable portion secured to the seal carrier segments. In addition, at least one spring is disposed on the seal carrier segment to exert a force and maintain the seal carrier segment adjacent to the rotatable component.

A method of transporting substrates comprising steps of: providing a substrate transport apparatus with a robot having a drive section with a rotationally stationary housing, a coaxial drive shaft assembly rotatably connected to the housing, and a pulley stationarily connected to the housing to form a rotationally stationary pulley, and a movable arm assembly connected to the drive section, the movable arm assembly having two driven arm assemblies individually connected to respective drive shafts of the coaxial drive shaft assembly; and rotating a first one of the drive shafts to thereby move a first one of the driven arm assemblies, the first driven arm assembly having an inner arm that is rotated with the first drive shaft and an outer arm that is rotated relative to the inner arm, wherein the outer arm is rotated relative to the inner arm by a first transmission belt connected between the outer arm and the rotationally stationary pulley of the drive section. 15. A method as in claim 14 wherein the step of rotating comprises rotating the first drive shaft about 180° to move the first driven arm assembly between two fully extended and opposite positions. 16. A method as in claim 15 wherein a distal end of the outer arm supports a substrate thereon and passes over the coaxial drive shaft assembly when the first driven arm assembly is moved between its two opposite fully extended positions. 17. A method as in claim 16 further comprising rotating a second one of the driven arm assemblies, the second driven arm assembly having an inner arm that is rotated with the second drive shaft and an outer arm that is rotated relative to the inner arm of the second driven arm assembly, wherein a second transmission belt is connected between the rotatably stationary pulley and the outer arm of the second driven arm assembly to rotate the outer arm of the second driven arm assembly relative to the inner arm of the second driven arm assembly as the second drive shaft is rotated. 18. A method as in claim 17 wherein the step of rotating the second driven arm assembly comprises rotating the second drive shaft about 180° to move the second driven arm assembly between two fully extended and opposite positions. 19. A method as in claim 18 wherein a distal end of the outer arm of the second driven arm assembly supports a substrate thereon and passes over the coaxial drive shaft assembly when the second driven arm assembly is moved between its two opposite fully extended positions. 20. A method as in claim 14 wherein the substrate transport apparatus is provided with a frame and a movement mechanism for moving the robot relative to the frame, the movement mechanism having a car movably mounted to the frame with the robot being attached to the car, wherein the method further comprises moving the car along the frame to move the robot with at least one substrate thereon relative to the frame. 21. A method of transporting substrates comprising steps of: providing a substrate transport apparatus with a drive section having a coaxial drive shaft assembly and movable arm assembly connected to the drive section, the movable arm assembly having two driven arm assemblies individually connected to respective drive shafts of the coaxial drive shaft assembly; and independently rotating the drive shafts to independently move the two driven arm assemblies, wherein each of the two driven arm assemblies is a general cantilevered arm assembly with an inner arm and an outer arm, and transmission belts connect the outer arms to a permanently rotationally stationary pulley on the drive section such that rotation of the inner arms cause the outer arms to rotate relative to their respective inner arms, wherein the permanently rotationally stationary pulley limits the two driven arm assemblies to only two fully extended positions relative to the drive section which are about 180° apart. 22. A method as in claim 21 wherein the step of independently rotating comprises rotating the drive shafts without rotating the pulley to move the substrates on the driven arm assemblies between the fully extended positions through a position over the coaxial drive shaft assembly. 23. A method as in claim 21 wherein the step of independently rotating rotates the two drive shafts in limited angles of fixed rotation of no more than about 180°. 24.
