    • Compact and inexpensive color printers can be manufactured. An exposure head using linearly-aligned organic EL elements each composed of subpixels each emitting light of R, G, and B is used as a light source. Input color image data are dealt with as color data corresponding to each of the color components R, G, and B. For each color data, each of the organic EL elements is caused to emit light in accordance with line data for one line corresponding to all organic EL elements composing the exposure head, and a photosensitive material is exposed to the light. After completion of the exposure, vertical scan means moves the photosensitive material by a predetermined amount in the vertical scan direction and the photosensitive material is exposed in accordance with image data corresponding to a subsequent line, as has been described above. By repeating this procedure, exposure corresponding to all image data is carried out.
    • 可以制造紧凑且便宜的彩色打印机。 使用每个由发射R,G和B的光的子像素组成的线性排列的有机EL元件的曝光头作为光源。 输入彩色图像数据作为与每个颜色分量R,G和B相对应的颜色数据处理。对于每个颜色数据,使每个有机EL元件根据对应于 构成曝光头的所有有机EL元件和感光材料暴露于光。 在曝光完成之后,如上所述,垂直扫描装置使感光材料沿垂直扫描方向移动预定量,并且根据与后续行对应的图像数据曝光感光材料。 通过重复该过程,执行对应于所有图像数据的曝光。

    • A silicon nitride ceramic sliding material comprising silicon nitride crystal grains and a grain boundary phase and having a porosity of 2 to 10% and a maximum pore size of 20 to 100 .mu.m. The silicon nitride ceramic sliding material preferably has a textural structure wherein the proportion of the total area of silicon nitride crystal grains of 0.1 to 10 .mu.m.sup.2 in area to the total area of all the silicon nitride crystal grains present in an arbitrary two-dimensional cross section is 30 to 90% and the proportion of the number of silicon nitride crystal grains of 2 to 10 in aspect ratio to the number of all the silicon nitride crystal grains present in that cross section is at least 20%. The material is produced by mixing a silicon nitride powder with a sintering aid powder, molding the resulting mixture, then heat-treating the resulting molded body in a nitrogen-containing atmosphere under reduced pressure at 1,000 to 1,500.degree. C., and then sintering it in a nonoxidizing atmosphere under ordinary pressure or under pressure, at 1,550 to 1,800.degree. C.
