摘要： An image printing apparatus comprises a storage section and a control section. The storage section stores an absorbing speed information in a storage area, the absorption speed information is a measured speed at which a recording medium used for a printing process absorbs an ink used for the printing process. And the control section controls an ink head so as to perform first dot recording which records a plurality of dots on the recording medium by a pitch of an ink ejection opening of the ink head, and moves the recording medium relatively with the ink head and controls the ink head so as to perform second dot recording which records a plurality of dots between a plurality of dots recorded by first dot recording, in accordance with a print interval time determined based on the absorption speed information stored in the storage section.

摘要： In an ink jet recording apparatus having two head units, each having a large number of ink nozzles arranged in a line, assembled so that they overlap with each other, an 8-shade image signal is entered into a correction circuit and a line direction position signal is input into a position signal decision circuit. When the position signal decision circuit decides that the position signal represents the overlapping zone of the head units, the shade level of the image signal is divided between the head units. For example, when the shade level of the image signal is 7, one of the head units is allotted the shade level and the other is allotted the shade level. The overlapping nozzles in a pair eject droplets of ink to form one dot.

摘要： An ink jet head is provided having ink chambers, energy-generating elements provided in the ink chambers, respectively, and ink outlet ports communicating with the ink chambers, respectively. The ink jet head may be left unused for a time longer than a predetermined time, with a meniscus formed in each ink outlet port. In this case, a drive pulse is applied to each energy-generating element several times, thereby forcing the ink outwards from the ink outlet ports and increasing a surface area of the ink from a surface area of the meniscus. Then, a negative pressure is applied in each ink chamber, thereby drawing the ink back toward the ink chambers, thus forming a meniscus again in the ink outlet ports. In this condition, a drive pulse is applied to the energy-generating elements, thus ejecting an ink droplet from the ink outlet ports to record data.

摘要： At least two or more than two ink-jet recording heads provided with respective discharge ports for discharging ink are arranged in the direction of conveyance of recording medium. The inks filled in the respective ink-jet recording heads are made to show different surface tensions. With this arrangement, as inks are discharged onto the recording medium that is conveyed by a conveyor under the control of a drive section, the image formed by the inks discharged onto the recording medium shows an improved quality.

摘要： In accordance with the dither matrix position signal from the dither matrix position signal generating unit, the dither matrix circuits supply respectively corresponding threshold signals to the selector. When the pixel of interest of the input image signal corresponds to two ink outlet ports at each end portion of the head units to be corrected, the selector selects the threshold signal from the end portion dither matrix circuit that is set for the end area, in accordance with the dither matrix selection signal from the dither matrix selection signal generating unit. Therefore, the comparator compares the input image signal with the threshold signal from the end portion dither matrix circuit and converts it into an N-valued signal.

摘要： Image data of 256 gradations is converted into that of 4 gradations which can be recorded by a recording head, at a pseudo-halftone processing unit and the converted image data is supplied to a head driving unit. A control signal selector selects a control signal A from a control signal A setting unit when the image data is a natural image, and a control signal B from a control signal B setting unit when the image data is a character or a line drawing. The head driving unit generates an electric signal used to drive the recording head on the basis of gradation information from the pseudo-halftone processing unit and the control signal A or B. With this operation, when the image data is a natural image, recording is carried out with a pixel dot for image formation excellent in gradation property, and when the image data is a character or a line drawing, recording is carried out with a pixel dot for image formation which causes no jaggy or blur to be generated at hatched portions and the like.

摘要： A magnetic resonance signal is acquired from a JHH-coupled 1H within an object. After application of a wideband first radio-frequency magnetic pulse, a first frequency-selective radiation pulse is applied to a specific nucleus 1H coupled to a desired nucleus 1H through a homonuclear spin-spin coupling (JHH-coupling), thus multiple-quantum coherences between the nuclei 1H being generated. A second radio-frequency magnetic pulse is then applied. A second frequency-selective radiation pulse is then applied to the specific nucleus 1H to generate a single-quantum coherence of the desired nucleus 1H. Thus, a magnetic resonance signal can be acquired from the desired nucleus 1H. The acquisition of the signal is robust, adjustment in the phases of the radio-frequency magnetic pulses is not required, and an acquired spectrum is avoided from being visually complicated.
摘要翻译： 从对象内的JHH耦合的1 H获取磁共振信号。 在应用宽带第一射频磁脉冲之后，通过同核自旋 - 自旋耦合（JHH耦合）将第一频率选择性辐射脉冲施加到耦合到期望核<1 H的特定核<1> H， 因此产生了核-1H之间的多量子相干。 然后施加第二个射频磁脉冲。 然后将第二频率选择性辐射脉冲施加到特定的核1 H以产生期望的核1 H的单量子相干性。 因此，可以从期望的核<1H获得磁共振信号。 信号的获取是鲁棒的，不需要调整射频磁脉冲的相位，并且避免所获得的光谱视觉复杂。
