    • An apparatus for optically checking magnetic disk defects that makes possible more accurate determination of positions of minute defects by illuminating an area greater than a checkup area with an illuminating beam having a Gaussian distribution is to be provided. The apparatus is configured of a specular reflection detecting device including a detector having a detecting face including an array of multiple pixels, and a processing device that figures out the position of each defect by using, in addition to the output signal from each of the pixels of the detector that detected a specular reflection from the checkup area, also output signals of some pixels out of the multiple pixels having detected the specular reflection from the checkup area of one turn before and the checkup area of one turn after, both adjoining in the radial direction, and determines the type of the defect.
    • 提供一种用于光学检查磁盘缺陷的装置,其能够通过用具有高斯分布的照明光束照射大于检查区域的区域来更精确地确定微小缺陷的位置。 该装置由包括具有包括多个像素的阵列的检测面的检测器的镜面反射检测装置构成,以及处理装置,除了来自每个像素的输出信号之外,还使用除去每个缺陷的位置 检测到来自检验区域的镜面反射的检测器的输出信号也输出从已经检测到来自前一轮的检查区域的检测区域的检测区域的多个像素中的一些像素的输出信号以及一匝之后的检验区域 径向,并确定缺陷的类型。

    • A combustion chamber structure for a direct injection diesel engine is provided which can increase recirculated amount of exhaust gas while avoiding generation of black smoke and deterioration of fuel efficiency as much as possible.Disclosed is a combustion chamber structure for a direct injection diesel engine having a cavity 10 on a top surface of a piston 9. The cavity is concave to provide a majority of the combustion chamber. Fuel is injected from a center of a cylinder top radially into an inner periphery of the cavity 10 to self-ignite. A depression 24 is formed at an outer periphery of the cavity 10 and is sunken relative to the top surface of the piston 9 to provide a step. The depression 24 has a bottom with an outer periphery gradually rising radially outwardly in modestly curved surface to the top surface of the piston 9. The inlet lip 11 is formed at a position lower than the top surface of the piston 9 by an inner periphery of the bottom of the depression 24 and a combustion chamber wall 12 rising from a bottom of the cavity 10.
