  • Electromagnetic linear motor with stator having cylindrical body of magnetically soft material and rotor having axially-magnetized permanent magnet
    Patent number: 8278785
    Abstract: An electromagnetic linear motor is proposed that features a longitudinal stator, a hollow body of the stator made of a magnetically soft material, a magnetic coil of the stator, a rotor in the stator that is movable linearly relative to the magnetic coil, an axially magnetized permanent magnet of the rotor and an axially variable shape or variable magnetic material properties of the stator.
    Type: Grant

  • Endoscope with sideview optics
    Publication number: 20040015049
    Abstract: An endoscope (1) is proposed with a rotatable side-viewing optics system (11), which has a mirror (15) for deflecting light onto an object to be examined and for reflecting the image of the object. A video camera (7) is located inside a hollow cylinder (6) that can be moved in rotation and the side-viewing optics system (11) is mechanically connected to the hollow cylinder (6) on the side that faces away from the viewing direction (12) of the video camera (7).
