摘要： A rolling bearing is disclosed of which the lifespan is increased by reducing brittle flaking and impression-induced flaking on the raceways of inner and outer races and the rolling elements. Steel containing 1.80-1.89% by weight of chrome (brittle flaking-resistant steel) is subjected to carbonitriding and then to hardening and tempering. The chrome reduces generation of white layers which are aggregates of carbon, thus reducing brittle flaking on e.g. the raceways (1a, 4a) due to the white layers. A residual austenite region (5) that forms when the steel is hardened and tempered increases toughness of the steel surface, thus reducing impression-induced flaking due to foreign matter such as wear dust. By reducing both brittle flaking and impression-induced flaking, it is possible to extend the lifespan of the bearing, and reduce maintenance cost such as the cost for changing lubricating oil.

摘要： The present invention has its objective to provide a defect classification apparatus which suppresses over-fitting and accurately classify the defect type of a defect. A defect classification apparatus is provided in which a data point indicating feature information of a defect to be classified having an unknown defect type is mapped to a point in a mapping space having a dimensional number higher than the number of features constituting the feature information, and the defect type of the defect to be classified is classified based on in which of two regions of defect type, which are formed by separating the mapping space by a decision boundary, the mapped point is located, wherein a discriminant function indicating the decision boundary is determined by adopting a weight which minimizes the sum of the classification error, which corresponds to the accuracy in classifying a training defect dataset, and a regularization term, which has a positive correlation with the dimensional number of the decision boundary, as the weight for each feature constituting the discriminant function.

摘要： A transmission apparatus which prevents adversely affects from an adjacent channel even without provision of a guard band. An information sequence 1 input to a mapping unit 21-1 of the transmission apparatus is mapped onto predetermined signal points by QAM modulation, etc. and output to a frequency converter 22-1. The frequency converter 22-1 converts the frequency according to a center frequency of an input signal and outputs the result to a multiplexer 23. The other data series are processed in the same way as the data series 1 are output to the multiplexer 23. The multiplexer 23 multiplexes a plurality of input signals, while an IFFT processor 24 performs an inverse Fourier transform on the multiplexed signals all at once. The inverse Fourier transformed signal is quadrature-modulated by a quadrature modulator 26, converted to the RF band signal by the frequency converter 28, and transmitted from an antenna 30.
