  • Patent number: 7518111
    Abstract: Below 50-nm-diameter extremely narrow electrically-conductive fiber is used instead of the electron beam biprism used in the conventional interference electron microscope method. A phenomenon is utilized where a focus-shifted shadow of this fiber is shifted from a straight line by a distance which is proportional to a differentiation of phase change amount of an electron beam due to a sample with respect to a direction perpendicular to the fiber. The phase change amount is quantified by calibrating this shift amount through its comparison with a shift amount caused by another sample in terms of which the corresponding phase change amount has been quantitatively evaluated in advance. The differentiation amount of the quantified phase change in the electron beam due to the sample is visualized, or eventually, is integrated thereby being transformed into absolute phase change amount to be visualized.

  • Publication number: 20080283748
    Abstract: An electron microscope for simultaneously adjusting the tilt, rotation and temperature of the specimen, and rapidly heating a desired localized section of the specimen. Specimen holders support the specimen on one side, and contain a space on the other side. A laser beam mechanism for heating the vicinity of the specimen irradiates a focused laser beam onto the specimen from this space. The output from a light position sensor installed in the specimen holders is utilized to adjust the irradiation position of the focused laser beam by controlling a fine motion mechanism for inputting light into the vicinity of the specimen stand.

  • Publication number: 20080210868
    Abstract: Chirality distribution in the molecular structure of protein or the like and magnetic domain structure are analyzed with high resolution less than 10 nm. A transmission electron microscope equipped with a spin-polarized electron source is used for holography observation. The phase of transmission spin-polarized electrons changes due to the existence of chirality structure or magnetization in a sample, which is observed as an interference pattern phase shift in holography measurement.

  • Publication number: 20080061484
    Abstract: A conventional solid protection device disposed on an exposed side of a cylinder for actuating a working device had a possibility of being permanently deformed by contacting an obstacle so as to be prevented from sliding properly corresponding to the telescopic movement of the hydraulic cylinder. An object of the invention is to provide a hardly deformable protection device. To protect an exposed side of a cylinder for a working device, a protection device 30 includes a guard member 32 and a slide guide 31 into which guard member 32 is telescopically fitted. Slide guide 31 is attached to a cylinder tube 9a, and a tip of guard member 32 is attached to a tip of piston rod 9b. Guard member 32 is a flat plate made of spring steel. A width of guard member 32 is larger than a diameter of the piston rod. Notches 32a are provided on lateral opposite sides of a basic side end of guard member 32. Sliders 33 are fitted to respective notches 32a.

  • Publication number: 20070175332
    Abstract: A gas purifying device has a re-circulating section configured to re-circulate liquid discharged from an element positioned on a downstream side of an airflow to reflow to a liquid circulation system path of an element positioned on an upstream side of the air flow. The liquid dissolves and removes low-concentration contaminants by gas-liquid contact. The liquid is discharged from the element on the downstream side and is made to reflow to the element on the upstream side through the re-circulating section. Contaminants are dissolved and removed by gas-liquid contact between the liquid and non-purified air containing high-concentration contaminants.

  • Publication number: 20050184254
    Abstract: An ion implantation method includes scanning reciprocatingly an ion beam in an X direction by an electric field or magnetic field and mechanically driving reciprocatingly a substrate in a Y direction orthogonal to the X direction to implant ions over the entire surface of the substrate. A dose distribution that is non-uniform within the plane of the substrate is formed within the plane of the substrate by changing at least one of a scanning speed of the ion beam and a driving speed of the substrate within an area where the ion beam is incident on the substrate.
