Abstract
Abstract A pressure-activated seal ring has an inner cylindrical surface (62) with a plurality of undulations (72) formed thereon and a substantially smooth cylindrical outer surface (58). The undulated areas permit fluid pressure to act on the inner surface so that the outer cylindrical surface will be forced into sealing contact with an adjacent surface (60).

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
130 words
A system for controlling a robot operating in association with a rotary table, comprising: a robot adapted to carry out an operation in at least two dimensions; a rotary table adapted to rotate in synchronization with the operation of said robot and to carry a workpiece; and a control circuit for interpolating teaching data on the workpiece and generating a signal for defining the operation of the robot and the rotary table; said control circuit carrying out a step of composing and storing teaching data as values on a rotary table coordinate system, the rotational shaft of said rotary table being the vertical axis, and a step of calculating each of the interpolation points by carrying out path interpolation of said stored teaching data on the rotary table coordinate system.
Claim 2
Independent Claim
130 words
A system for controlling a robot operating in association with a rotary table, comprising: a robot adapted to carry out an operation in at least two dimensions; a rotary table adapted to rotate in synchronization with the operation of said robot and to carry a workpiece; and a control circuit for interpolating teaching data on the workpiece and generating a signal for defining the operation of the robot and the rotary table; said control circuit carrying out a step of composing and storing teaching data as values on a rotary table coordinate system, the rotational shaft of said rotary table being the vertical axis, and a step of calculating each of the interpolation points by carrying out path interpolation of said stored teaching data on the rotary table coordinate system.
Claim 3
Dependent Claim
84 words
A system according to claim 1, wherein said control circuit further carries out a step of calculating the rotational angle of the rotary table which is required to be rotated, a step of computing the coordinates rotated by said rotational angle around the axis of rotation of said rotary table, a step of transforming the data obtained by said computing step from the rotary table coordinates to the robot coordinates, and a step of operating said robot by the output of the transformation step.
