    摘要: A wheel has both wear resistance and heat-crack resistance sufficient for use in a high-speed railway vehicle. The chemical composition of a base steel comprises 0.4 to 0.75 % C, 0.4 to 0.95% Si, 0.6 to 1.2% Mn and less than 0.2% Cr. The wheel has a pearlitic microstructure in a region of at least 50 mm in depth from the tread surface of the wheel. When the tread of the wheel is quenched, a particular cooling process is applied in order to obtain the pearlitic structure.

    摘要: A method for easily and effectively preventing shattered-rim fracture in a railway wheel. Generally, the method comprises the steps of providing a railway wheel, measuring the maximum defect size within the rim of the railway wheel, and determining whether the maximum defect size is less than a predetermined maximum permissible defect size, the maximum permissible defect size being determined based on an analysis of the likelihood of Mode II crack propagation from the defect when the railway wheel has been subjected to the load. The disclosed invention also encompasses a method for grading railway wheels for maximum load suitability.

    摘要: A fundus analyzing apparatus 1 performs OCT measurements of a fundus Ef and generates multiple tomographic images that each depict layer structures of the fundus Ef. Each formed tomographic image is stored in a storage 212. Based on the pixel values of the pixels of each tomographic image, the layer-region identifying part 233 identifies the layer region corresponding to the pigment layer of the retina. Based on the shape of the layer region, the curve calculator 234 obtains a convex standard curve in the direction of depth of the fundus Ef. Based on the layer region and the standard curve, a protrusion-region identifying part 235 identifies protrusion regions where the layer region protrudes in the opposite direction from the direction of depth of the fundus Ef. A morphological-information generating part 236 generates morphological information representing the morphology (number, size, distribution, etc.) of the protrusion regions.

    摘要: In a method of manufacturing a semiconductor device, a passivation film made of a polyimide resin film is formed on a front surface of a semiconductor wafer including a scribe line and an outer circumferential portion. Thereafter, only the passivation film which is formed on the scribe line of the semiconductor wafer and on the outer circumferential portion of the semiconductor wafer is selectively removed. A protective tape is then bonded onto the front surface of the semiconductor wafer, followed by grinding of a rear surface of the semiconductor wafer.
