  • Patent number: 11164720
    Abstract: To measure a depth of a three-dimensional structure, for example, a hole or a groove, formed in a sample without preparing information in advance, an electron microscope detects, among emitted electrons generated by irradiating a sample with a primary electron beam, an emission angle in a predetermined range, the emission angle being formed between an axial direction of the primary electron beam and an emission direction of the emitted electrons, and outputs a detection signal corresponding to the number of the emitted electrons detected. An emission angle distribution of a detection signal is obtained based on a plurality of detection signals, and an opening angle is obtained based on a change point of the emission angle distribution, the opening angle being based on an optical axis direction of the primary electron beam with respect to the bottom portion of the three-dimensional structure.

  • Patent number: 10974372
    Abstract: An impact driver includes a hammer that is rotated by a motor and an anvil configured to be struck by the hammer to rotate the anvil about a rotational axis. A hammer case houses the hammer. Two or more bearings are provided inside the hammer case and support the anvil. To inhibit vibration of the anvil during operation, the bearings may be differing types, such as a regular ball bearing and an angular contact ball bearing, and/or the bearings may have different inner and/or outer diameters. A contact member, such as an O-ring, may be disposed in an insertion hole of the anvil to reduce vibrations that are transmitted to the tool bit.
