Abstract: Flash fixing equipment for fixing a toner image onto a medium by means of flashlight is to reduce non-uniformity of halftone image print density. Flash fixing unit has flash energy distribution consisting of a center zone and front/end zones. The flash frequency of the flash lamp is controlled so that the toner fixing start energy being subtracted from the added value of flash energies of front and end zones becomes substantially equal to the flash energy value on the center zone. The energy distribution exceeding the fixing start energy which affects print density (size of toner-overflowed area) is controlled to have a flat characteristic to reduce non-uniformity of print density.

Abstract: An apparatus for controlling outputting of web data including: a receiving section (2) for receiving direction information of a direction to output web data, which direction information has been issued by a user; a web data obtaining section (3) for obtaining the web data that is processed into a web page which the user wishes to output on the basis of said direction information received in said receiving section (2); an output data creating section (4) for creating output data by extracting beneficial web data that is of benefit to the user from the obtained web data; and an output controlling section (5) for controlling the output device (15) to output the output data created by said output data creating section. With this apparatus for controlling outputting of web data, when web data processed into a web page provided on the Internet is to be output from the output device, it is possible for a user to obtain the output data in the convenient form to the user.

Abstract: An ink drop is injected via a nozzle by changing drive voltages applied to a piezoelectric element to reduce the volume of a pressure chamber filled with ink, so that the injected ink drop hits upon a print medium to carry out printing. Upon injecting the ink drop via the nozzle, an injection timing of the ink drop is changed corresponding to a drive frequency of the drive voltages using a predetermined rule. The predetermined rule may be a table defined in terms of drive frequencies of the drive voltages and optimum injection timings of the ink drop corresponding to the drive frequencies.

Abstract: A halftone printing is realized by jetting ink drops of mutually different sizes toward a print medium. Among them, the ink drop having the middle size is set to be a reference ink drop for determining injection timings of the ink drops. When the ink drop to be jetted is bigger than the reference ink drop, an injection timing thereof is delayed relative to that of the reference ink drop. On the other hand, when the ink drop to be jetted is smaller than the reference ink drop, an injection timing thereof is advanced relative to that of the reference ink drop. This allows all the ink drops to be hit upon the print medium precisely at given positions.

Abstract: The instant invention has an exemplified object to provide an inkjet head and recording device having such an inkjet head with a simpler structure as achieves higher quality of printing inexpensively than the conventional. The pressure-chamber plate of this invention is slit or divided into a plurality of elements.

Abstract: An ink jet head including a piezoelectric element having a displacing portion, a pressure chamber plate bonded to the piezoelectric element for defining a common ink chamber and a plurality of pressure chambers in cooperation with the piezoelectric element, and a nozzle plate bonded to the piezoelectric element and the pressure chamber plate and having a plurality of nozzles respectively communicating with the plurality of pressure chambers. Each pressure chamber is connected to the common ink chamber through a plurality of ink supply channels each having a substantially square cross-section.

Abstract: A method of manufacturing an ink jet head includes the following steps, wherein the ink jet head is provided with a plurality of pressure chambers arranged continuously, ink feed means for feeding ink into these pressure chambers, and ink ejecting means for ejecting ink from each pressure chamber via a nozzle, so as to feed and eject ink by a change in volume of each pressure chamber. First, a first metallic film is formed on both surfaces of at least one wall composing the pressure chamber perpendicular to an arranging direction of the plurality of pressure chambers, wherein the at least one wall is one wall of a piezoelectric element deformed when a voltage is impressed. Then, the first metallic film formed on one of the both surfaces of at lest one wall is removed to form an exposed surface of the wall of the piezoelectric element.
