  • Patent number: 11949834
    Abstract: An image reading device includes linear image sensors that are arranged so that adjacent image sensors include an overlapping region in which portions of reading regions of the adjacent image sensors overlap in a main scanning direction, and a buffer unit for read image data. Image data of each overlapping region are generated by synthesizing first image data obtained by a first linear image sensor and second image data obtained by a second linear sensor, the first linear image sensor and the second linear sensor being adjacent in the main scanning direction. Image data of the predetermined line is generated based on image data in which the image data of each overlapping region are excluded from the image data stored in the buffer unit and the image data of each overlapping region. The processing is repeatedly executed in a sub-scanning direction.

  • Patent number: 7679734
    Abstract: In a fiber optic block 10 formed by bundling and integrating a plurality of optical fibers 11 each composed of a core region 12 and a clad region 13, an at least partially curved input end face 14 composed of one end of each optical fiber and a measurement surface having a curved surface shape of a to-be-measured object are pressed against each other. Then, an optical image formed by bringing the input end face into contact with the measurement surface and output from an output end face 15 of the fiber optic block is used to inspect the curved surface shape of the to-be-measured object. This allows a curved surface shape inspection method capable of inspecting the shape of a curved surface easily, a fiber optic block, and a curved surface shape inspection apparatus to be achieved.

  • Patent number: 7655891
    Abstract: The present invention relates to a charged-particle detecting apparatus having a structure which enables adjustment of a potential distribution so as to stably maintain flight loci of charged particles without depending on a change in a voltage-applied state. The charged-particle detecting apparatus comprises a first electrode, an MCP, a second electrode, a third electrode that functions as an anode, and a rear cover arranged in order along a predetermined reference axis. The third electrode is arranged on the opposite side of the MCP with respect to the second electrode, and is electrically connected to an output signal part via a capacitor.
