| 20090109254 | IMAGE FORMING APPARATUS - The present invention teaches and claims an image forming apparatus comprising: an image forming portion including one or more inkjet heads for forming an image on a recording medium by discharging ink from an ink discharge surface of the inkjet head; a recording medium transporting portion having a transport surface which is positioned below the ink discharge surface and on which the recording medium is placed for transporting a sheet to a position facing the ink discharge surface; a moving mechanism for moving the transport surface toward and away from the ink discharge surface; an ink discharge surface protecting mechanism including but not limited to a cap member and a driving device for moving the cap member; and a control unit for moving the transport surface away from the ink discharge surface to operate the ink discharge surface protecting mechanism when the recording medium is jammed during transportation of the recording medium. | 04-30-2009 |
| 20090267980 | IMAGE FORMING METHOD, IMAGE FORMING APPARATUS AND INKJET HEAD - An image forming method for use in an inkjet head includes a pressure chamber filled with ink, a nozzle which communicates with the pressure chamber and in which a meniscus of the ink is formed, a piezoelectric element which pressurizes the pressure chamber, and a drive circuit which performs an operation of ejecting the ink in a printing state and generates a basic pulse for vibrating the meniscus in a non-printing state. The basic pulse is generated by turning off a voltage applied to the piezoelectric element for substantially the same period as a natural vibration period of the ink. An additional pulse is generated at least once before or after the basic pulse when the basic pulse is generated by the drive circuit in the non-printing state. The additional pulse is generated by turning off the voltage applied to the piezoelectric element. | 10-29-2009 |
| 20100201730 | IMAGE FORMING APPARATUS, IMAGE FORMING METHOD, AND HEAD DEVICE - An image forming apparatus may include a head having: nozzles which eject ink for one pixel onto a recording medium; pressurization chambers coupled to the nozzles, and a pressure application portion. The pressure application portion may execute an ejection operation and/or a swinging operation. The ejection operation may include ejecting the ink from the nozzles. The swinging operation may enable swinging of meniscus of the ink in the nozzles and disable ink ejection. In some embodiments, a print control portion may control the ejection operation in the pressure application portion, and a swing control device may control the swing operation. In some embodiments, the swing operation may be directed at specific nozzles based upon image data scheduled to be printed. | 08-12-2010 |

| 20090246687 | AZO-METAL CHELATE DYE AND OPTICAL RECORDING MEDIUM - The azo-metal chelate dye to which the present invention is applied is a compound formed as follows: for example, 1,3,4-thiadiazole ring is selected as the diazo component; the diazo component is combined with a coupler component having condensed rings including a fluorine-substituted alkylsulfonylamino group and an amino group, to form an azo dye compound; and the azo dye compound forms chelate bonds with at least one metal selected from the group consisting of Co, Ni, Cu and Pd. Here, two absorption bands (OD1 and OD2) are seen in the absorption spectrum, which is measured in a range of 400 to 800 nm wavelengths. The azo-metal chelate dye is characterized in that the optical density ratio (OD2/OD1) of the two absorption bands is greater than 1.25. By using this azo-metal chelate dye, an optical recording medium capable of high-speed recording is provided. | 10-01-2009 |
