摘要:
An optical axis alignment apparatus 10 has a chuck 13 for holding an optical member 14, a chuck 16 for holding an optical member 15, a pushing mechanism, which pushes the chuck 1 to generate a predetermined frictional force between the optical member 14 and the optical member 15, and actuators 18A to 18D. The actuators 18A to 18D have a piezoelectric element 51b which generates an impulsive inertial force by abrupt extension and contraction.

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.

A process and apparatus for rapidly producing an emulsion and microcapsules in a simple manner is provided wherein a dispersion phase is ejected from a dispersion phase-feeding port toward a continuous phase flowing in a microchannel in such a manner that flows of the dispersion phase and the continuous phase cross each other, thereby obtaining microdroplets, formed by the shear force of the continuous phase, having a size smaller than the width of the channel for feeding the dispersion phase.

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.

A microinjection apparatus according to the invention includes a microsyringe having a plunger, a rotative moving member which rotates together with a shaft, and a micromovement device mounted on the rotative moving member and having a piezoelectric/electro-strictive element equipped with an inertial member. Applying an electric signal to the micromovement device produces a driving force which causes the rotative moving member to rotate by a minute amount. As a result, the plunger is moved a minute amount in the axial direction to move a liquid within the microsyringe. Also provided is a microinjection apparatus which includes a microsyringe having an internal rotary plate serving as a plunger and attached to a center shaft, a rotative moving member which rotates together with the center shaft, and a micromovement device mounted on the rotative moving member and having a piezoelectric/electro-strictive element equipped with an inertial member. Applying an electric signal to the micromovement device produces a driving force which causes the rotative moving member to rotate by a minute amount. As a result, the rotary plate serving as the plunger is rotated a minute amount to move a liquid within the microsyringe. Further, the microinjection apparatus is so adapted that a micromovement device having a piezoelectric/electrostrictive element equipped with an inertial member is driven to drive a rectilinear moving member directly in a linear direction, thereby operating a plunger.
