  • Patent number: 10410908
    Abstract: A plate-like base of a substrate holder has an upper surface perpendicular to a central axis. A supporter is disposed circumferentially around the central part of the base and protrudes upward from the upper surface of the base to support the lower surface of a substrate. A flexible seal is disposed around the entire periphery of the supporter. An upper edge portion of the seal is located above the supporter. When the substrate holder adsorbs a substrate, gas present between the base and the substrate is sucked through a suction port with the upper edge portion of the seal being in contact with the lower surface of the substrate. This allows the substrate to approach the base and come in contact with the supporter while making the seal bend down. As a result, even if there is a warp in a substrate, the substrate can be held suitably.

  • Patent number: 10378518
    Abstract: A main shaft fixture for fixing a main shaft on a wind turbine during installation and repair work on heavy parts of the wind turbine nacelle, in the case where the fixture is formed of several sections for mounting on stable structural parts in the nacelle, including the nacelle's bottom frame. The main shaft fixture has adjustable pressure mandrels with tap shoes, which cause the fixture to be usable regardless of the turbine main shaft geometry, such that it can be mounted without fixing the rotor. The main shaft fixture also has facilities for mounting of a lightweight crane and a self-hoisting crane with a ground-based winch, respectively, as well as a rotor lock which, in combination with actuators of the main shaft fixture, enables the main shaft and the main shaft bearing to be sufficiently displaced vertically from its bearing in the nacelle to service or replace the bearing.
