  • Publication number: 20200300606
    Abstract: A method for producing a preparation for fiber length measurement includes: a preliminary dispersion process of adding fibers and a dispersion medium with a viscosity of 500 Pa·s to 10,000 Pa·s to a sealable container so as to give a concentration of the fibers of 0.1% by mass or less and shaking the container to prepare a preliminary dispersion liquid; a dispensing process of dispensing part of the preliminary dispersion liquid to another sealable container; a dilution process of adding the dispersion medium to the dispensed preliminary dispersion liquid so as to give a concentration of the fibers of 0.005% by mass or less and shaking the container to prepare a dispersion liquid for measuring fiber length; and a casting process of spreading part of the dispersion liquid for measuring fiber length onto a base having light transparency.

  • Patent number: 7928376
    Abstract: There is provided an element mapping unit, scanning transmission electron microscope, and element mapping method that enable to acquire an element mapping image very easily. On the scanning transmission electron microscope, the electron beam transmitted through an object to be analyzed enters into the element mapping unit. The electron beam is analyzed of its energy into spectrum by an electron spectrometer and an electron energy loss spectrum is acquired. Because the acceleration voltage data for each element and window data for 2-window method, 3-window method or contrast tuning method are already stored in a database and accordingly the spectrum measurement is carried out immediately even when an element to be analyzed is changed to another, the operator can confirm a two-dimensional element distribution map immediately.

  • Patent number: 5367171
    Abstract: A specimen cartridge fashioned of a good thermal conductor, with an outer frame being fashioned of heat insulating material, and with a connecting rod being fashioned of a poor thermal conductor. A temperature distribution of the specimen is uniform and a temperature drift is reduced, with a thermal expansion of a specimen cartridge tilting rod not affecting the tilting angle, thereby making it possible to perform various highly accurate observations and measurements with an electron microscope.
