A method of sealing a nozzle. First, a device comprising a chamber, a nozzle, and a nozzle plate is provided, wherein the nozzle plate is installed on the chamber and the nozzle passes through the nozzle plate and connects the chamber. The chamber is then filled with ink. Residual ink on the nozzle plate is then removed by water. After that the nozzle plate is dried, a solution is then coated on the nozzle plate, wherein the solution has higher surface tension than the ink and has smaller contact angle with the nozzle plate than the water. Next, the nozzle plate is dried. Finally, a flexible material is bonded on the nozzle plate to seal the nozzle.

An optical detector measuring a movement of an object in a space on a measurement axis comprises a light source, a reflective portion, a detection unit and a converting unit. The light source comprises a resonance chamber, the light source emitting a laser beam toward the object, the laser beam contacting the object and generating a first scattering beam and a reflection beam, wherein a part of the first scattering beam enters the resonance chamber. The reflective portion reflects the reflection beam toward the object, the reflection beam re-contacting the object and generating a second scattering beam and a sub-reflection beam, wherein a part of the second scattering beam and the sub-reflection beam enter the resonance chamber. The detection unit measures an optical-electrical variation in the resonance chamber to generate an electric signal. The converting unit converts the electric signal to a movement on the measurement axis in the space.

A fluid ejection apparatus. The fluid ejection apparatus includes a chamber, a manifold, an orifice, a first bubble generating element and a second bubble generating element. The chamber contains fluid. The manifold is connected to the chamber. The fluid flows into the chamber at a first direction through the manifold. The orifice is connected to the chamber. The first bubble generating element is disposed above the chamber and close to the orifice to generate a first bubble. The first bubble generating element is substantially parallel to the first direction. The second bubble generating element is disposed above the chamber and is substantially parallel to the first direction to generate a second bubble. The second bubble generating element is close to the orifice and opposite to the first bubble generating element. The fluid in the chamber is ejected via the orifice by the first and second bubbles.
