  • Patent number: 10036424
    Abstract: A method is disclosed for replacing grease in a main bearing of a wind turbine, the main bearing located in a housing and the housing having least one cover plate. the bearing cover plate is removed from the housing, grease is manually removed from the main bearing, and a flushing cover is installed on the housing in place of the bearing cover plate. The flushing cover has at least two parts, the parts fitting around the main shaft, and each part having a seal so that when its attached to the bearing housing, the flushing cover forms a seal with the main shaft. The flushing cover has holes allowing access to the main bearing, and a solvent or oil is sprayed via one of the holes onto the main bearing to remove grease, the remaining holes being sealed by a removable plug. Solvent or oil is pumped out of the housing via a port at the bottom of the housing or flushing cover.

  • Patent number: 9953826
    Abstract: A method for cleaning a substrate includes supplying to a substrate a film-forming processing liquid which includes a volatile component and forms a film on the substrate, vaporizing the volatile component in the film-forming processing liquid such that the film-forming processing liquid solidifies or cures on the substrate and forms a processing film on the substrate, supplying to the substrate having the processing film a strip-processing liquid which strips the processing film from the substrate, and supplying to the processing film formed on the substrate a dissolving-processing liquid which dissolves the processing film after the supplying of the strip-processing liquid.

  • Patent number: 9931017
    Abstract: An apparatus and method for washing and drying objects includes a rotating washing fluid sprayer having several nozzles to direct washing fluid, e.g., water, at an object being washed in a chamber. A drying fluid is directed at the object in the chamber to dry the object. The drying fluid, e.g., air, is directed in a spiral pattern against the object to urge washing liquid away from the object to dry the object and to push the drying liquid away from edges of the object. The air may be directed at the object simultaneously with the water to increase the energy with which the water impinges on the object and to urge dirt from the object being washed.

  • Patent number: 9895041
    Abstract: A cleaning device may include a solution tank configured to store cleaning solution. The device delivers the cleaning solution from a pump discharge of the cleaning device to a flow meter. The device initiates a priming mode by opening a first valve associated with a bypass line of the device, closing a second valve associated with a cleaning head of the cleaning device, and delivering the cleaning solution from a discharge of the flow meter to the inlet of the solution tank through the bypass line. When the device is primed, it initiates cleaning by closing the first valve associated with the bypass line, opening the second valve associated with the cleaning head, and delivering the cleaning solution to the cleaning head.

  • Patent number: 9887107
    Abstract: Rinsing methodologies and components to accomplish rinsing of tool surfaces in tools that are used to process one or more microelectronic workpieces. The invention can be used to rinse structures that overlie a workpiece being treated in such a manner to function in part as a lid over the process chamber while also defining a tapering flow channel over the workpiece. Rather than spray rinsing liquid onto the surface in a manner that generates undue splashing, droplet, or mist generation, a swirling flow of rinse liquid is generated on a surface of at least one fluid passage upstream from the surface to be rinsed. The swirling flow then provides smooth, uniform wetting and sheeting action to accomplish rinsing with a significantly reduced risk of generating particle contamination.

  • Patent number: 9881784
    Abstract: Disclosed is a substrate processing method. The method includes: supplying a rinse liquid, IPA, a first fluorine-containing organic solvent, a second fluorine-containing organic solvent to a wafer within an outer chamber of a liquid processing unit; conveying the wafer to a supercritical processing unit container; and supplying a supercritical processing fluorine-containing organic solvent in a supercritical high-pressure fluid state to the wafer within the supercritical processing unit container. At least during the supply of the IPA, a low-humidity N2 gas is supplied into the outer chamber so that the inside of the outer chamber is formed as a low-humidity N2 gas atmosphere, and thus moisture absorption into the IPA is prevented.

  • Patent number: 9859110
    Abstract: An ultrasonic wave applying liquid is supplied to one principal surface of a substrate while a liquid film of a first liquid being formed on another principal surface of the substrate. The ultrasonic wave applying liquid is obtained by applying ultrasonic waves to a second liquid. Ultrasonic vibration is transmitted to the other principal surface and the liquid film, thereby ultrasonically cleaning the other principal surface. The first liquid has a higher cavitation intensity, which is a stress per unit area acting on the substrate by cavitation caused in the liquid when ultrasonic waves are transmitted to the liquid present on the principal surface of the substrate, than the second liquid.
