摘要:
An inkjetting device for an inkjet printer includes a plurality of nozzle plates arranged in a parallel line, and a pair of magnets installed on respective upper and lower portions of the nozzle plates. Each nozzle plate includes a pair of parallel levers, which are connected to a bridge at one end portion and separated from each other at the other end portion, and a nozzle orifice to jet ink is formed on a front face of the bridge. Ink is stored in ink chambers respectively formed between the levers of the pairs of parallel levers. By applying an electric current to each lever in the magnetic field formed by the pair of permanent magnets, a Lorentz force affects each lever to move closer to the other one of the pair of parallel levers. Accordingly, the ink is jetted onto printing paper to execute a printing operation.

摘要:
A light emitting diode (LED) array module includes a plurality of LEDs; and a substrate which mounts the LEDs and has a built-in cooling device for cooling heat generated when the LED is driven. The cooling device includes a heat radiation space formed on the substrate and a minute passage member which is wick- or mesh-structured to form a plurality of minute passages that operate by a heat pipe principle in the heat radiation space. The cooling device operating by the heat pipe principle is integrally formed on the substrate mounted with the LEDs, so heat radiation performance of the LEDs is enhanced, such that the LEDs can operate stably for a long time.
