    • An image forming device includes a feeding unit, a recording unit, and a controller. The feeding unit includes a first feeding member and a second feeding member disposed at a downstream of the first feeding member in a feeding direction. At least one of the first feeding member and the second feeding member feeds a recording medium in the feeding direction. The recording unit is disposed between the first feeding member and the second feeding member to eject a plurality of ink droplets onto the recording medium fed between the first feeding member and the second feeding member. A plurality of ink droplets ejected onto the recording medium forms a plurality of raster lines extending in a main-scanning direction orthogonal to the feeding direction. The controller controls the recording unit to eject a plurality of ink droplets so that a plurality of first raster lines formed within a first time span has a first resolution in the feeding direction, a plurality of second raster lines formed within a second time span has a second resolution in the feeding direction, and a plurality of third raster lines formed within a third time span including a banding timing at which a trailing edge of the recording medium gets away from the first feeding member has a third resolution higher than the first resolution in the feeding direction. The second time span follows the first time span and the third time span follows the second time span. The second resolution is higher than the first resolution and lower than the third resolution.

    • Object of this invention is to provide a plasma CVD method capable of forming a microcrystalline silicon film at low hydrogen gas flow rate, thereby providing a low-cost microcrystalline silicon solar cell.In the plasma CVD method forming the microcrystalline silicon film, plural antennas are arranged to form an antenna array structure in a vacuum chamber. One end of each antenna is connected to a high frequency power source and anther end is grounded. Substrates are placed facing the antenna arrays, and the substrate temperature is kept between 150 and 250° C. Plasma is generated by introducing gas mixture of hydrogen and silane to the chamber, and by introducing high frequency power to the antennas. When hydrogen/silane gas flow ratio is controlled in the range from 1 to 10, microcrystalline silicon films are formed on the substrates with the ratio Ic/Ia between 2 and 6, whereas Ic and Ia are the Raman scattering intensity at around 520 cm−1 and at around 480 cm−1, related to crystalline silicon and amorphous silicon, respectively

The antenna elements are arranged in plane in such a way that the first and second linear conductors are alternated and separated from one another at regular intervals, thereby forming one or more array antennas which are disposed in a chamber. The second ends of the first linear conductors are connected to a high-frequency power supply, and the second ends of the second linear conductors are connected to ground. A plurality of substrates are parallel placed on both sides of the array antennas at distances approximate to the distances between the linear conductors.

    • The user determines his/her desired color state in accordance with the color maps prepared in accordance with the color system corresponding to the human visual sense. The LUT characteristic values Lmin, amin, bmin, astep, and bstep are adjusted into adjusted values L′min, a′min, b′min, a′step, and b′step based on the user's designated color adjustment amounts &Dgr;L, &Dgr;C, &Dgr;RG, and &Dgr;YB. Then, based on the adjusted LUT characteristic values and the inputted Lab color data (Lx, ax, bx), discrimination number sets (Lgrid, agrid, bgrid) are determined for eight lattice points surrounding the inputted color data. With using CMY data sets (Ci, Mi, Yi) for the eight lattice points, an interpolation calculation is achieved to calculate a CMY control data set (Cx, Mx, Yx) for the inputted color data set (Lx, ax, bx).
