摘要： An inkjet head (1) has a liquid flow path section (3) for receiving liquid and, in response to application of a voltage, ejecting the liquid to an object on which a drawing is to be made. The degree of design freedom of the shape of the liquid channel section (3) or the shape of a liquid channel in the liquid channel section (3) can be improved because the liquid channel section (3) is formed on the upper surface of a substrate. Furthermore, the inkjet head can have a structure corresponding to the properties of liquid to be ejected or to an object to which the liquid is to be ejected.

摘要： An ink jet printhead with an array of nozzles 3. A chamber 7 and a heater 14 correspond to each nozzle respectively. The heater has a heater element 10 extending between a pair of electrodes 15. The heater elemen 10 is suspended in the chamber 7 by the electrodes 15 to heat printing fluid and generate a vapour bubble to cause a drop of the printing fluid to eject through the nozzle 3. Integrated circuit metalization layers corresponding to each of the nozzles supply electrical energy to the heater 14. The heater 14 and the integrated circuit metalization layers 23 are substantially planar and at least partially overlapping, the metallization layers electrically connected to the heater electrodes 15 by vias, the cross sectional area of all the vias being greater than 50% of the surface area of one side of the heater 14. A relatively large number of vias lowers the electrical resistance between the electrodes and the CMOS metalization layers. Lower resistance reduces the power losses and improves the operating efficiency of the printhead.

摘要： Disclosed are a droplet ejection device and method using an electrostatic field. The droplet ejection method includes: setting a separate electric field direction in each of a plurality of nozzles; supplying one of ink and ink containing particles to each nozzle; and forming and ejecting a plurality of separate ink droplets. The droplet ejection device includes a deposition part having electrode layers and insulating layers deposited toward a nozzle. Therefore, it is possible to readily perform droplet ejection without a heater or diaphragm vibration device. In addition, it is possible to reduce impact applied to the ink and obtain good print quality, since the ink is ejected using the electrostatic field.
