    • A disclosed flange member includes a press-fitted portion to be press-fitted in an axial end-opening portion of a hollow and cylindrical sleeve member; an axle opening portion including an axle opening into which a shaft member is inserted when the press-fitted portion is press-fitted in the end-opening portion; and a linking portion extending in a direction parallel to a circular cross section of the sleeve member and connecting the axle opening portion to the press-fitted portion. The linking portion includes a stress-absorbing portion that is deformed so as to absorb stress to which an outer peripheral surface of the press-fitted portion is subjected upon contact with an inner peripheral surface of the sleeve member when the press-fitted portion is press-fitted in the end-opening portion, thus preventing the stress from being transmitted to the axle opening portion via the linking portion.
    • 所公开的凸缘构件包括压配合部分,该压配部分压配合在中空和圆柱形套筒构件的轴向端部开口部分中; 所述车轴开口部包括车轴开口,当所述压配合部压配合在所述端部开口部时,所述轴构件插入到所述轴孔中; 以及连接部,其在与所述套筒构件的圆形截面平行的方向上延伸并将所述车轴开口部连接到所述压入部。 连接部分包括应力吸收部分,该压力部分被变形以吸收当按压配合部分被按压时压配部分的外周面与套筒部件的内周面接触时受到的应力 设置在端部开口部分,从而防止应力通过连接部分传递到车轴开口部分。

    • A light emitting apparatus 10 includes an aluminum nitride co-fired substrate 11 and a light emitting device 12 arranged on a front surface of the co-fired substrate, in which the front surface of the aluminum nitride substrate 11 bearing the light emitting device 12 is mirror-polished so as to have a surface roughness of 0.3 μm Ra or less, and the light emitting apparatus 10 further includes a vapor-deposited metal film 14 and via holes 15. The vapor-deposited metal film 14 is arranged on the front surface of the aluminum nitride substrate 11 around the light emitting device 12 and has a reflectivity of 90% or more with respect to light emitted from the light emitting device 12. The via holes 15 penetrates the aluminum nitride substrate 11 from the front surface bearing the light emitting device 12 to the rear surface to thereby allow conduction to the light emitting device 12 from the rear surface. This configuration can reduce light emitting apparatuses in size and can provide light emitting apparatuses that are excellent in heat radiation performance, allow a larger current to pass therethrough, and can have a significantly increased luminance with a high luminous efficiency.
    • 发光装置10包括氮化铝共烧基板11和布置在共烧基板的前表面上的发光装置12,其中承载发光装置12的氮化铝基板11的前表面是 镜面抛光以使表面粗糙度为0.3μmRa或更小,并且发光装置10还包括气相沉积金属膜14和通孔15。 蒸镀金属膜14配置在发光元件12的周围的氮化铝基板11的正面上,相对于从发光元件12发出的光的反射率为90%以上。 通孔15从承载发光器件12的前表面穿过氮化铝衬底11到后表面,从而允许从后表面导电到发光器件12。 这种结构可以减小发光装置的尺寸,并且可以提供散热性能优异的发光装置,允许较大的电流通过,并且可以以高发光效率显着提高亮度。
