  • Object stage bearing for lithographic apparatus
    Patent number: 11442369
    Abstract: An object stage bearing system can include an object stage, a hollow shaft coupled to the object stage, and an in-vacuum gas bearing assembly coupled to the hollow shaft and the object stage. The in-vacuum gas bearing assembly can include a gas bearing, a scavenging groove, and a vacuum groove. The gas bearing is disposed along an inner wall of the in-vacuum gas bearing assembly and along an external wall of the hollow shaft. The scavenging groove is disposed along the inner wall such that the scavenging groove is isolated from the gas bearing. The vacuum groove is disposed along the inner wall such that the vacuum groove is isolated from the scavenging groove and the gas bearing.

  • Density meter for slurry
    Patent number: 9915596
    Abstract: A density meter for slurry which is transported through a pipe, the density meter including: a pipe part; flexible pipe couplings arranged on either end of the pipe part; a force sensor for measuring a force in the direction of the at least one degree of freedom between the pipe part and a fixed point; an accelerometer arranged on the pipe part for measuring the accelerations of the pipe part in the direction of the at least one degree of freedom; and computing means for computing the density of the slurry in the pipe part on the basis of the volume of the pipe part, the force measured by the force sensor and the acceleration measured by the accelerometer.
