    • A surface inspection apparatus includes a light source for applying a detection laser beam to a film sample. A light receiver has plural photomultiplier tubes arranged in a width direction of the film sample, for receiving output light reflected by the film sample. A defect detector detects a defect on the film sample according to an output signal output by each of the photomultiplier tubes. A sensitivity corrector sets sensitivity of the photomultiplier tubes to process an output of the light receiver for output noise suppression. Specifically, the sensitivity corrector determines a set sensitivity of the photomultiplier tubes by correcting a sensitivity characteristic thereof for abnormality detection, to keep a sensitivity difference between the photomultiplier tubes as small as a predetermined value or less. Furthermore, plural light valves upstream from the light receivers are controlled by the sensitivity corrector for their transmittance.
    • 表面检查装置包括用于将检测激光束施加到膜样品的光源。 光接收器具有沿胶片样本的宽度方向排列的多个光电倍增管,用于接收被膜样品反射的输出光。 缺陷检测器根据由每个光电倍增管输出的输出信号检测胶片样品上的缺陷。 灵敏度校正器设置光电倍增管的灵敏度来处理光接收器的输出以用于输出噪声抑制。 具体地,灵敏度校正器通过校正用于异常检测的灵敏度特性来确定光电倍增管的设定灵敏度,以将光电倍增管之间的灵敏度差保持为预定值或更小。 此外,由光接收器上游的多个光阀由透射率的灵敏度校正器控制。

    • A light-shielding packaging for a roll of continuous photosensitive web wound on a core having on its both ends a light-shielding flange disc has at its leading end a heat-shrinkable light-shielding leader sheet having a thickness of 30 to 200 &mgr;m which shows a heat shrinkage ratio of 5 to 30% in the longitudinal direction of the web at a temperature in the range of 60 to 140° C. and a heat shrinkage ratio of less than 5% in its width direction at the same temperature. The leader sheet has a length larger than the length of the outermost convolution of the roll and a width larger than the distance between the outer face of one flange disc and the outer face of another flange disc, and each side portion of the leader sheet is light-tightly attached by heat shrinkage to the outer face of the flange disc at least at a portion adjacent to the periphery of the flange disc.
