摘要： An inkjet recording apparatus may include a conveyor belt, suction unit, linear recording heads, and head frame shaped like a plate. The conveyor belt has a placement face on which a recording medium is placed and may be configured to cause the placement face to move in a conveyance direction. The suction unit disposed below the placement face applies a suction force exerted by a downward airflow to the recording medium placed on the placement face. The linear recording heads may be disposed upward opposite to the suction unit across the conveyor belt, have a nozzle face where an ink ejection nozzle is formed, and extend in a direction orthogonal to the conveyance direction. Linear recording heads may be arranged in the conveyance direction. The linear recording heads may be attached to the head frame. The head frame may have a ventilation opening penetrating in a thickness direction.

摘要： 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.

摘要： An inkjet head includes a passage unit and an actuator unit. The passage unit includes a common ink chamber and an individual ink passage leading from an outlet of the common ink chamber through a pressure chamber to an ejection port. The actuator unit can selectively take a first state in which the volume of the pressure chamber is V1 and a second state in which the volume of the pressure chamber is V2 larger than V1. The actuator unit changes from the first state into the second state and then returns to the first state to eject ink from the ejection port. The individual ink passage is formed such that the volume Vd of a partial passage in the individual ink passage corresponding to a region from an outlet of the pressure chamber to the ejection port, and the volume Vc of the individual ink passage, satisfy a condition that Vd/Vc is not less than 0.12 and not more than 0.40.

摘要： 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.
