Abstract: A liquid ejection head includes a piezoelectric block body having a plurality of pressure chambers arranged two-dimensionally to face respective ejection ports, a plurality of air chambers arranged adjacently relative to the plurality of pressure chambers, and a plurality of flow channels arranged along the pressure chambers. The pressure chambers are deformed by expansion and contraction of piezoelectric members disposed between the pressure chambers and the air chambers so as to drive the liquid stored therein to flow toward the ejection ports. A connection flow channel is provided at the ejection port side of the piezoelectric block body so as to make each of the pressure chambers communicate with at least one of the flow channels for partial recirculation of the ink.

Abstract: In a continuous liquid ejection apparatus, when pressurizing ink with a pump and initiating ejection, the problem of a stable ink column and droplets not being formed if ink is ejected in a low ink pressure state and large droplets or droplets with unstable flight directions being formed is solved. The space where droplets fly is sealed in order to raise the pressure of ink inside a liquid chamber communicating with a nozzle up to a pressure suitable for droplet-forming condition, while the pressure of gas in the sealed space is raised corresponding to the rise in pressure of the liquid to suppress ejection from the nozzle. After the pressure of the ink is raised to pressure suitable for droplet-forming condition, the sealed space is opened to the atmosphere and ink is ejected all at once.

Abstract: A liquid applicator suitable for manufacturing probe arrays comprises a liquid ejection section having a plurality of sets of a liquid ejecting nozzle adapted to eject liquid onto a medium, a liquid containing section communicating with the liquid ejecting nozzle and a supply port for supplying liquid to the liquid containing section, a liquid supply section having a liquid supply member arranged therein to store liquid to be applied and adapted to supply liquid to the liquid ejection section by way of the supply ports, an information recording body arranged at the liquid ejection section and/or the liquid supply member of the liquid supply section and an information reading device adapted to read information recorded in the information recording body.

Abstract: An image processor reads an original that includes an original image and an attribute instruction image, for designating the contents of the image processing that is performed on the original image. This ensures that image processing is performed in consonance with the contents of the attribute instructions that are indicated by the attribute instruction image. A scanner reads a format original wherein instructions for data attributes, such as a range for a character frame and a character color, are expressed with a bar code. The pattern of the read bar code is analyzed, and the attribute instruction data, such as the range for a character frame and a character color, are temporarily stored in a RAM. An original to be output is read by the scanner and is stored as image data in the RAM. Image processing (color conversion, etc.) that correspond to the attribute instruction data is performed on the image data, and a printer prints image data obtained by performing all of the instructed image processes.

Abstract: A liquid crystal driving apparatus comprises a plural number of first signal lines arranged on the front surface of a liquid crystal panel, a plural number of second signal lines arranged on the back surface of the liquid crystal panel in the direction intersecting the first signal lines at right angles, third signal lines arranged between the first signal lines, fourth signal lines arranged between the second signal lines, and a time division driving signal generator and a selection driving signal generator. The time division driving signal generator supplies time division driving signals to the first and fourth signal lines. In synchronism with the time division driving signals generated by the time division driving signal generator, the selection driving signal generator supplies selection driving signals to the second and third signal lines.
