  • Patent number: 10622183
    Abstract: The present invention relates to a charged particle beam apparatus enabling a selection of a charged particle beam in a specified energy range by symmetrically arranging cylindrical electrostatic lenses deflecting a path of the charged particle beam and disposing an energy selection aperture between the cylindrical electrostatic lenses. Since an integral structure in which a central electrode and a plurality of electrodes that are arranged at a front portion and a rear portion in relation to the central electrode of a monochromator are fixed to each other through insulator, is applied, a mechanism for adjusting an offset with respect to an optical axis is simplified as compared to the case of separately providing the lenses at the front portion and the rear portion, respectively, and a secondary aberration is canceled in an exit plane due to symmetry of an optical system.

  • Patent number: 9985496
    Abstract: The invention relates generally to a step actuator, in which a lead screw coupled with a screw thread formed in a nut member is installed in a rotor magnet and moves back and forth in an axial direction responding to a rotation of the rotor to transmit power in an axial direction. A cylindrical bearing for rotatably supporting the nut member is disposed at an upper part of the nut member and integrally formed therewith, to fundamentally remove a gap in the axial direction in the coupled area between the cylindrical bearing and the nut member, thereby significantly reducing the feeding error of a rotator in the axial direction when the lead screw moves back and forth in the axial direction, and reducing the number of parts to be assembled to lower the material cost and the labor cost for assembly.
