20130182024 | INKJET HEAD AND AN INKJET RECORDING DEVICE - According to one embodiment, the inkjet head of an application example includes a pressure chamber for charging the ink, an actuator for changing the volume of the pressure chamber, a nozzle for discharging the ink inside the pressure chamber when the volume of the pressure chamber is changed, and a controller that, in the formation of one pixel by discharging ink drops from the nozzle, when the elapsed interval from discharging ink drops last time by the nozzle is less than the specified interval, outputs the discharging waveform corresponding to the ink drop number determined for the formation of the pixel, and when the elapsed interval is more than the specified interval, increases the number of ink drop discharge cycles above the number determined for the formation of the pixel. | 07-18-2013 |
20130215172 | INKJET HEAD AND INKJET RECORDER - According to one embodiment, an inkjet head has a pressure chamber for storing an ink, an actuator for changing the volume of the pressure chamber, and a nozzle through which the ink stored in the pressure chamber is ejected when the volume of the pressure chamber is changed. Additionally, the inkjet head has a temperature sensor for detecting the temperature of the ink and a controller for controlling the actuator by outputting an ejecting waveform. The ejecting waveform sequentially includes an expansion pulse, a first contraction pulse, and a second contraction pulse. The controller changes the pulse width or voltage value of the second contraction pulse when the temperature detected by the temperature sensor changes. | 08-22-2013 |
