摘要:
A method and an apparatus for producing various types of microdroplets. The apparatus has a cross intersection portion at which a first continuous phase, a first dispersion phase, and a second dispersion phase intersect with each other. A first liquid feed device controls the first dispersion phase and a second liquid feed device controls the second dispersion phase. A control device is connected to the first liquid feed device and the second liquid feed device. The first liquid feed device and the second liquid feed device are controlled by a signal from the control device so that microdroplets formed of the first dispersion phase and microdroplets formed of the second dispersion phase are sequentially produced.

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.

An elastic surface wave gyroscope includes two transducers attached on a piezoelectric substrate to generate elastic surface waves having different frequencies on the piezoelectric substrate, and two pair of reflectors for reflecting the different elastic surface waves toward the generators to produce two different standing waves, and another pair of reflectors for reflecting an elastic surface wave caused by a Coriolis force to produce a third standing wave, and a detector for detecting an electric signal corresponding to the third standing wave. This gyroscope has a high detection sensitivity.
摘要:
A ferromagnetic member (21) of a movable part (2) is disposed on a side of a stationary part (1) such that the ferromagnetic member (21) faces a high temperature superconductor (11) of the stationary part (1). The high temperature superconductor (11) is brought into a superconductive state by cooling it to a temperature below a critical temperature in a magnetic field. The magnetic flux pinned to the high temperature superconductor (11) is caused to pass through the ferromagnetic member (21) so that an attractive force is generated between the high temperature superconductor (11) and the ferromagnetic member (21) to hold the movable part (2). When the ferromagnetic member (21) has a shape such that when the gap becomes lower than a predetermined value, the attractive force decreases, the movable part (2) can be stably suspended in a non-contacting manner, without the necessity of control, by the combination of the high temperature superconductor (11) and the ferromagnetic member (21).

A multiple axes drive apparatus having a plurality of electrostatic actuators for applying driving forces in a plurality of different directions within a plane to a driven member. Each electrostatic actuator of the drive apparatus includes a first member that has a plurality of first electrode strips arranged in a single direction with a predetermined pitch, and a second member that has a plurality of second electrode strips arranged in the same direction as the first electrode strips with the same pitch. The members are located opposite to each other so one of the members moves along the single direction in response to a Coulomb force generated between the electrode strips when voltage is applied to the electrode strips.
