  • Publication number: 20180072054
    Abstract: An ink-jet recording apparatus includes: a recording head including first and second nozzles and first and second driving elements corresponding to the first and second nozzles respectively; a controller; and a head driving circuit connected to the controller by first and second signal lines and a third signal line for transmitting a clock signal, the head driving circuit connected electrically to the first and second driving elements. Each of the first and second driving elements is driven to jet an ink droplet from one of the first and second nozzles corresponding thereto when driving voltage is applied from the head driving circuit. The controller executes relative movement processing for the recording head and a sheet in parallel with recording processing in which pattern signals of the driving voltage are outputted serially to the first signal line and a jetting instruction signal is outputted serially to the second signal line.

    Abstract: An ink-jet recording apparatus includes: a conveyor conveying a sheet; a recording head including first nozzles, second nozzles, first driving elements corresponding to the first nozzles respectively, and second driving elements corresponding to the second nozzles respectively; a controller; and a head driving circuit connected to the controller by first and second signal lines and a third signal line through which a clock signal is transmitted, and connected electrically to the first driving elements and the second driving elements. Each of the first and second driving elements is driven to jet an ink droplet from one of the first and second nozzles when driving voltage is applied from the head driving circuit. The controller repeatedly executes conveyance processing for conveying the sheet with the conveyor and recording processing in which pattern signals indicating patterns of the driving voltage are outputted serially and a jetting instruction signal is outputted serially.

  • Patent number: 9796188
    Abstract: A liquid discharging device including a liquid discharging head with nozzles, a carriage, and a controller is provided. When a position of the end of a sheet is on an inner side of an outmost contact part among a plurality of contact parts along a scanning direction, the controller determines discharging timings to discharge liquid from the nozzles based on first gap information, which is related to a gap between the sheet and the liquid discharging surface and is stored in a gap information storage. When the position of the end of the sheet is on the inner side of the outmost contact part, the controller determines the discharging timings based on the first gap information stored in the gap information storage and on second gap information generated in a gap information generating process.

  • Publication number: 20170282549
    Abstract: A printing apparatus, including a conveyor, a liquid ejection head with nozzles, a carriage, a carriage movement mechanism, and a controller, is provided. The controller executes a printing operation including a parameter determining process and an ejection timing determining process. In the parameter determining process, a value to a correction parameter is determined. In the ejection timing determining process, ejection timing to eject liquid through the nozzles is determined based on the value to the correction parameter. In the ejection timing determining process, the controller determines the ejection timing by shifting the ejection timing to be at least one of later and earlier than a reference timing for a time length corresponding to the value to the correction parameter. In the parameter determining process, the controller provides a different value to the correction parameter for the scan-printing action in the second unit-printing process depending on the nozzle shift amount.

  • Patent number: 6905307
    Abstract: The stator vane is provided with a leading edge which is cut into a different depth in dependence on a span-wise position so that a blade inlet angle may vary along a span-wise direction according to a prescribed pattern. By thus optimizing the depth of the cut along the leading edge of the stator vane, the leading edge blade inlet angle can be optimized along the entire length of the stator vane even if the stator vane consists of a two-dimensional aerofoil, and the vane is provided with a substantially conformal cross section in parts which are not affected by the cut in the leading edge. Thereby, the efficiency of the turbine can be optimized while minimizing the cost.
