  • Patent number: 8785850
    Abstract: New methods for phase contrast imaging in transmission electron microscopy use the imaging electron beam itself to prepare a hole-free thin film for use as an effective phase plate, in some cases eliminating the need for ex-situ fabrication of a hole and reducing requirements for the precision of the ZPP hardware. The electron optical properties of the ZPP hardware are modified primarily in two ways: by boring a hole using the electron beam; and/or by modifying the electro-optical properties by charging induced by the primary beam. Furthermore a method where the sample is focused by a lens downstream from the ZPP hardware is disclosed. A method for transferring a back focal plane of the objective lens to a selected area aperture plane and any plane conjugated with the back focal plane of the objective lens is also provided.

  • Publication number: 20140024006
    Abstract: A question setting apparatus is disclosed, including a processor and a storage part. The storage stores problem information which maintains problem data including a problem and a correct answer of the problem included in a test sent to students, and student answer information which maintains answer data and a correct/incorrect answer determination result for each of the students. The processor processes test operations of referring to the problem information, sending the problem data to the student terminals, receiving the answer data from the student terminals in a given time for the test, and recording the answer data in the student answer information. The processor processes a progress display. A progress state is displayed in the given time and indicates an answer state of the problem data based on the correct/incorrect answer determination result. A display instruction is sent to the student terminals to stop the test.
