  • Patent number: 8217346
    Abstract: An optical microscope for optically measuring a sample (30) includes: a fluorescent thin membrane (13) which at least partly contains fluorescent substance and on which the sample (30) is placed; an electron source (11) for generating an electron beam; an electron lens (12) for focusing the electron beam generated by the electron source (11) in such a manner as to excite a minute light source having a wavelength shorter than a visible light wavelength from the fluorescent thin membrane (13) so as to irradiate the fluorescent thin membrane (13) with the electron beam, and further, scanning the focused electron beam; and an optical detector (22) for detecting a measurement light beam which is generated in the minute light source and acts on the sample (30).

  • Publication number: 20020150825
    Abstract: An optical recording method suited for recording a very small object or movement of a living organism such as a microorganism, which comprises irradiating an informative object set on or above a recording layer comprising a photosensitive material capable of undergoing a storable and detectable photochemical reaction, preferably a polymer material containing a photoreactive component capable of photoisomerization and having in the repeating unit thereof at least one group selected from a urethane group, a urea group, an amide group, a carboxyl group and a hydroxyl group, and recording a distribution of an optical near field generated from the informative object being irradiated on the photosensitive material as a photoreacting quantity of the photosensitive material.

  • Patent number: 4502924
    Abstract: In case that the surface of a mold for continuous casting of steel made of copper or copper alloy having at least partially nickel or nickel-base alloy plated thereon is injured, said surface is abraded without complete removal of said plated layer, the resulting exposed surface is dipped with concentrated strong acid for activation, and thereafter it is repaired by plating nickel or nickel-base alloy thereon.
