    摘要: An electromagnetic micro positioner, e.g. for use in fibre optics, is operated by a ceramic piston (8) mounted within a ceramic cylinder (5). The piston (8) is moved by a permanent magnet (9) and an electromagnetic circuit (1/2). By changing the coil (2) polarity the piston (8) will either be attracted or repelled to its top or bottom position. In particular the core (1), capable of polarity reversal, has a magnetic remanence by means of which the movable piston (8) is fixable in one of the two predefined positions when the coil (2) is not energized.

    摘要: A bobbin-less coil and a method of manufacturing the bobbin-less coil. In the method, a pair of disk-like guide members (65) and (66) are brought into contact with the axial both end faces of a conductor (61) wound in a coil shape by using a separable tool. Parts of the conductor (61) are engaged with engagement parts (65c) and (66c) formed around the pair of guide members (65) and (66) and the pair of guide members are energized in directions for moving them close to each other, and then the tool is separated from the center of the conductor (61). By this, the shape of the bobbin-less coil (46) in which the inner peripheral surface of the conductor (61) wound in the coil shape is exposed can be retained. Also, since the pair of disk-like guide members (65) and (66) are energized in the directions for moving them close to each other by utilizing the parts of the conductor (61), the need of a special material for energization can be eliminated.
