Title: Method and device for evaluating damage in bearing
Inventor: ODA MASAHIRO
IPC: G01H17/00
Filed: 2000-05-15
Abstract: PROBLEM TO BE SOLVED: To provide a method and device for evaluating damages in a bearing, capable of easily evaluating damage in a bearing using a new technique.

In the case that the ratio of the average amplitude Va to the maximum amplitude Vm becomes high, it is decided that the damage in the bearing has developed. For example, it is decided that the bearing is damaged, in the case that the maximum amplitude Vm and average amplitude Va satisfy the relationship of the expression Va=Vm/C-(Vm.exp(-C))/(1-exp(-C))+BGN (where C is a constant; and BGN is a background noise level).

Title: Structure of blade of large windmill
Inventor: ITO KANICHI
IPC: F03D11/00
Filed: 2000-04-06
Abstract: PROBLEM TO BE SOLVED: To solve problems that it is impossible to thin the blade made of a lightweight material of low rigidity, such as a fiber-glass reinforced plastic or the like used as a material of the blade of a large windmill, which causes the noise by the vortex produced near a tip part of an outer periphery of a blade, particularly at a high speed, and the flattering phenomenon, the vibrational fault and the impairing of the performance by the deflection and torsion of the blade. SOLUTION: The tip part of the outer periphery of the blade is made of a metallic material having high elastic modulus and high specific gravity such as stainless steel, and connected to a blade mounting member at a hub side by means of a tension rod of lightweight and high strength such as carbon fiber. By applying this constitution, a thickness of the tip part of the outer periphery of the blade can be remarkably reduced, whereby not only the noise caused by the vortex can be reduced, but also the deflection and the torsion of the blade can be recovered as the blade is radially pulled by the weight effect (centrifugal force) of the metallic material, and the flattering phenomenon, the vibrational fault or the like caused by the turbulence of the wind can be prevented effectively.
