Abstract: For a serial color ink jet printing apparatus that forms an image using a symmetric printing head that ejects large dots and small dots, the configuration of a printing head is provided for suppressing, to the extent possible, a cyclic fluctuation in the main scanning direction. According to the present invention, individual nozzle arrays are arranged so that two nozzle arrays, i.e., a cyan nozzle array c1 and a magenta nozzle array m1, that are located nearer each other, form dots on adjacent scan lines. With this arrangement, a high quality image, having neither an uneven density nor an uneven color, can be formed when a printing head is inclined, or when a cyclic shift in printing positions occurs, depending on the position of the main scanning direction.

Abstract: It is an object of the present invention to provide a liquid applying apparatus which can prevent an applying liquid from evaporating while an applying operation is at a stop and which can reliably prevent the liquid from leaking even when for example, the posture of the apparatus is tilted. Thus, according to the present invention, an abutting member of a holding member is abutted, under an urging force of a spring, against an applying surface of an applying roller. Thus, a liquid holding space is formed between the applying roller and a holding member to hold the applying liquid. The abutting member is annularly formed of a single member. The applying roller rotates to cause the applying liquid held in the holding space to adhere to an outer peripheral surface of the applying roller. The applying liquid is then applied to the applying medium.

Thus, a diffusion film can be produced simply and at low cost.

Abstract: If print agents used are detected by an optical sensor at different sensitivities, the present invention enables the easy setting of adjustment values for print positions resulting from these print agents. To accomplish this object, for example, the present invention substitutes and sets adjustment values for print positions resulting from cyan, light cyan, or black ink, corresponding to a high detection sensitivity, for adjustment values for print positions resulting from a light magenta, yellow, or magenta ink, corresponding to a low detection sensitivity.

Abstract: A necessary amount of suppression ink is applied to each portion of an ink absorber in a short time and in an efficient manner. For that end, carriage scan is performed while changing an ejection condition of suppression ink so as to change an application amount of suppression ink according to a position of an ink absorber. This makes it possible to appropriately apply suppression ink, which suppresses accumulation of ink, to the entire area of the ink absorber by carriage scan in a short time even if an application amount of accumulation ink differs from part to part of the ink absorber.

Abstract: A controller generates printing data to be printed by the printing nozzles of at least first and second adjacent printing nozzle arrays out of a plurality of printing nozzle arrays on the basis of tone information of image data to be printed. In particular, the controller generates printing data to be printed by each of the first and second printing nozzle arrays in the range in which the influence of an air flow generated along with ink discharge from the first and second printing nozzle arrays is admissible. Printing by the first and second printing nozzle arrays of the printhead is controlled on the basis of the generated printing data.

Abstract: An object of the present invention is to provide a liquid applying apparatus which can inhibit a variation in application amount associated with the individual variability of a component of the apparatus. According to the present invention, a liquid holding space in which a liquid is held is formed between the applying member and the liquid holding member. When the applying member moves, the liquid attached to the applying member is fed out of the liquid holding space together with the applying member. The liquid is applied to a medium. The application amount of liquid applied to the applying medium varies depending on the individual variability of a component such as a liquid applying member. The variation in liquid application amount is adjusted by adjusting section for adjusting, the rotation speed of the liquid holding member or the flow speed of the liquid flowing through the liquid holding space.

Abstract: A parallel groove of a light guide place for accommodating a light source has, in a perpendicular cross section, a shape composed of a pair of contour lines that approach each other toward a light emitting plane, cross at a peak, and has a part where an inclination angle to a line vertical to the light emitting plane changes, and the inclination angle at a base end side far from the peak is sharper than that at a tip end side close to the peak. Thus, uniform and high brightness light can be emitted.

Abstract: This invention provides a printing apparatus which employs a print head constructed to minimize a memory area to hold ejection data and not requiring a sophisticated manufacturing technology and thus realizes a print mode to perform a higher-than-normal-resolution printing, making it possible to form a high quality image when needed. For each of cyan and magenta that make large contributions to the formation of an image, four nozzle arrays are allocated. For each of the remaining colors, two nozzle arrays are allocated. For cyan and magenta, the interval between adjoining nozzles of the paired two arrays is set to ¼ the nozzle pitch. For cyan and magenta, all of the four nozzle arrays are used in the high resolution print mode and, in the normal print mode, only two of the four nozzle arrays are used for printing. Of the paired adjoining nozzle arrays, only one is used.

Abstract: A multi step index optical fiber includes at least two concentrically arranged core portions, each having constant refractive index. The refractive indices of the core portions decrease toward the outer periphery of the optical fiber. The refractive indices of the core portions are set such that differences ?N between refractive indices of adjacent core portions are uniform, and the distribution of the refractive indices approximates a G power distribution. Thereby, bandwidths on the order of several GHz/l00 m can be realized.

Abstract: The present invention provides an optical sheet having one generally planar surface and composed of transmissive material, wherein on the other surface of the optical sheet, a concavo-convex pattern formed of a convex portion having a triangular top portion and a concave portion of a surface parallel to the one surface of the optical sheet is formed alternately in a generally parallel array.

Abstract: It is an object of this invention to provide a ternary or higher-order quantization method which avoids close gathering of pixels at a first output level. First and second threshold values Lth1 and Lth2 for ternarization and output values 0 (blank), 1, and 2 as converted output values are set to have a relationship of output value of 0 (blank)<first threshold value Lth1<second threshold value Lth2<output value of 1<output value of 2. This prevents a quantization error from becoming 0 when an input pixel value is an intermediate value, and prevents continuous outputting of only pixels having the output value of 1. When this image is printed, small ink dots corresponding to the output value of 1 are not easily continuously printed. This improves the image quality.

Abstract: A first data sequence generated by a first moving picture coding system having an intra-frame coding mode and an inter-frame coding mode is transformed to a second data sequence generated by a second moving picture coding system having an intra-frame coding mode and an inter-frame coding mode. The method includes prereading a coding mode of a successive frame succeeding a present frame from the first data sequence, judging whether or not a preread coding mode of the successive frame is the intra-frame coding mode and determining whether or not to code the present frame by the second moving picture coding system corresponding to a generated code amount of the second data sequence when the coding mode of the successive frame is the intra-frame coding mode. Data coded by the intra-frame coding mode existing in the first data sequence is transformed to the second data sequence.
