  • Patent number: 8188427
    Abstract: A method and apparatus for alignment and astigmatism correction for a scanning electron microscope can prevent an alignment or correction error attributable to the conditions of a particular specimen. First, a difference is determined between optimal values acquired from an automatic axis alignment result on a standard sample, and those obtained from each of a plurality automatic axis alignment results on a observation target sample. An optimal value is then adjusted using the standard sample, by use of the difference thus obtained. Correspondingly, an optimal stigmator value (astigmatism correction signal) is acquired by using the standard sample, and storing the optimal stigmator value as a default value. The optimal stigmator value and the default value depending on the height of an observation target sample pattern are added, and an astigmatism correction is performed on the basis of the resultant stigmator value.

  • Patent number: 8052146
    Abstract: Provided is a sheet inverting apparatus wherein members, such as a roller, are not brought into contact with the printed surface of a sheet at all, and the occurrence of dirt can be prevented by eliminating friction of ink on the surface of the sheet. A first transport apparatus and a second transport apparatus each have a plurality of transport belts which move on transport tracks along sheet transport directions and a suction box which sucks the sheet on the transport belts through suction holes formed on the transport belts. A turn guide arranged between the first transport apparatus and the second transport apparatus has a plurality of guide ribs disposed between the transport belts. Each of the guide ribs coming into slidable contact with the sheet forms a curved inverting transfer surface from an inversion starting point side to an inversion end point side.
