摘要： A roller bearing includes: inner and outer rings; rollers interposed between raceway surfaces of the inner and outer rings and having a roller outer circumferential surface; a cage retaining the rollers; and a DLC film on the roller outer circumferential surface. The DLC film includes a superficial layer having cavities provided therein to hold a lubricating agent. The rollers have a ratio of surface area occupied by the cavities of 40% or less, and the cavities have a size of 10 to 100 μm when viewed in a plan view thereof. The DLC film can have a multilayered structure in which the superficial layer is layered on an additional layer, and the cavities can include a void of soft DLC present in the superficial layer and having a film hardness lower than that of the additional layer.

摘要： Disclosed is a wind turbine blade extending from a root end to a tip end, the wind turbine blade comprising a root region, and an airfoil region comprising the tip, a pressure side, a suction side and a chord extending between a leading edge and a trailing edge. The wind turbine blade comprises a leading edge protection element at the leading edge of the wind turbine blade. The leading edge protection element extends in a longitudinal direction between an outboard end and an inboard end and comprises a first section extending from the outboard end to a first section position, wherein the first section is made of a first erosion protection material having a first erosion resistance, and a second section extending from the first section position to a second section position, wherein the second section is made of a second erosion protective material having a second erosion resistance. The first erosion resistance is larger than the second erosion resistance.

摘要： A device, system, and method for recirculation of water and energy generation comprises a reservoir and a device that facilitates water flow from the reservoir. The system is used to implement a method for energy generation. The device is configured to minimize friction by utilizing hydrophobic coatings on the inner walls of the device. One-way valves prevent water that has entered the device from going back onto the water reservoirs. Hydrophilic and hydrophobic interactions are further utilized to maintain the water flow. The system then generates a circulating water fall that is used to drive an electrical generator or similar device, such as turbines and dynamos, to generate electricity.

摘要： A rotor blade comprising fiber-reinforced plastic for a wind power plant is provided with a radar absorber embedded into the fiber-reinforced plastic. The rotor blade includes a layer close to the surface with a defined electrical sheet resistivity of 100 to 800 ohm/square, which is located at a depth of 2 to 5 mm below the surface. The rotor blade also includes a layer far removed from the surface with a defined electrical sheet resistivity of at a maximum 50 ohm/square at a distance to the layer close to the surface of 5 to 16 mm. The integrated radar absorber covers one or several discrete surface sections of the rotor blade, without covering the entire surface of the rotor blade.
