A gripper mechanism and a movement mechanism which utilize an electromagnetic actuator which can secure a sufficient thrust force at least at a certain level over a wide range of displacement. The movement mechanism includes a pair of electromagnetic actuators disposed inside a pair of rails and an intermediate actuator provided between the electromagnetic actuators. The electromagnetic actuators function as a gripper mechanism to be gripped by the rails. The electromagnetic actuators each include a displacement amplification mechanism including a magnetic body, and coils provided in the displacement amplification mechanism. A magnetic flux is generated in the magnetic body by passing an electric current through the coils so as to displace the displacement amplification points of the displacement amplification mechanism.

Gripper mechanism and movement mechanism

There is provided an electromagnetic actuator which can secure a sufficient thrust force at least at a certain level over a wide range of displacement. The electromagnetic actuatorhaving a point of amplified displacement includes: a displacement amplification mechanismA made of a magnetic material and having two surfacesthat form a gaptherebetween; and a coilprovided in the displacement amplification mechanismA. A magnetic flux is generated by passing an electric current through the coil, thereby generating an attraction force between the surfaces. The attraction force displaces the point of amplified displacement.

Monodisperse colored spherical particles each having two separated color regions of two hues, that is, two-colored spherical particles, useful, for example, for displays of characters, graphics, images and the like, the two hues being for reverse display in terms of electricity and magnetism from the viewpoint of good suitability for display are provided. In the production process and the apparatus for producing the colored spherical polymer particles, microchannels are utilized including a first microchannel through which a colored continuous phase comprising a color dye/pigment dispersed in a fluid dispersing medium containing a polymerizable resin component and having colored phases of different hues is transferred, and a second microchannel through which a spheroidizing disperse phase flows. The process and apparatus spheroidizes the discharged colored continuous phase having two hues and cures the polymerizable resin component in the colored continuous phase, whereby colored spherical polymer particles are formed.
