  • Patent number: 10226922
    Abstract: An ink jet head includes a substrate having a pressure chamber formed therein, the pressure chamber being in communication with a nozzle through which ink is to be discharged, a first plate that is deformable to change a volume of the pressure chamber, and a second plate between the first plate and the pressure chamber, that stretches in response to an electric signal applied thereto. The second plate contracts in an in-plane direction to cause the first plate to deform and thereby the volume of the pressure chamber to be enlarged, when the electric signal is applied, and the second plate returns to an original shape thereof to cause the first plate to return to an original shape thereof and thereby the volume of the pressure chamber to return to an original volume thereof, when the electric signal is no longer applied.

  • Patent number: 10137686
    Abstract: An ink jet head includes a pressure chamber connected to a nozzle, an actuator configured to cause liquid in the pressure chamber to be ejected from the nozzle by deforming a wall of the pressure chamber, and a drive circuit configured to apply voltage to the actuator to drive the actuator. When a droplet of the liquid is ejected from the nozzle, the voltage applied to the actuator is changed from a first value to a second value that causes the pressure chamber to expand, and then changed from a third value that is equal to the second value or between the first value and the second value to the first value after a time period ?, which is a primary natural oscillation period of the actuator when the pressure chamber and the nozzle are filled with the liquid.

  • Publication number: 20170304744
    Abstract: A dispersed mobile-phase countercurrent chromatography system is described in which solutes are carried by a stream of dispersed mobile phase solvent through a column, or array of serially-connected columns, of stationary phase solvent with which the mobile phase solvent is immiscible. Solutes carried along by the stream of dispersed mobile-phase solvent will be equilibrated between the mobile-phase solvent and the stationary-phase solvent. Because the mobile-phase is dispersed into mini-droplets much smaller in diameter than the column of stationary phase, the enhanced surface/volume ratio of the droplets expedites countercurrent equilibration of different solutes between the mobile-phase solvent and the stationary-phase solvent in accordance with the distribution-coefficients of the solutes between the two solvents.

  • Patent number: 9046387
    Abstract: A transmissive optical encoder is disclosed. The transmissive optical encoder includes a detector, a code wheel, and an emitter. The detector includes an aperture through the detector. The aperture is configured to receive a rotary shaft of a motor. The code wheel is coupled to the rotary shaft of the motor. Rotation of the rotary shaft results in corresponding rotation of the code wheel. The emitter is configured to emit a light signal through the code wheel toward the detector. Rotation of the code wheel results in modulation of the light signal at the detector. Embodiments of the transmissive optical encoder consume relatively little space and facilitate alignment of the emitter and detector.
