    • This invention provides an image forming apparatus capable of outputting, without using any special device, an image which is free from changes in density and tint even upon crisscross rotation and exhibits good proportion of a small character. To accomplish this, the pulse width of a laser emission signal is controlled at 16 levels for one dot at 600 dpi, controlling an actual image in the main scanning direction. When adjusting vertical and horizontal line widths, patch data are created by rotating an anisotropic pattern through 0° and 90° (S1 in FIG. 5). Then, a reader/scanner (15) reads each patch as density data (S2 in FIG. 5). A pulse width, that is, line width correction value at which the densities of the patch patterns rotated through 0° and 90° become equal to each other is obtained (S3 in FIG. 5).
    • 本发明提供了一种图像形成装置,即使在使用任何特殊装置的情况下,也能够即使在十字形旋转时也能够输出密度变化和色调的图像,并且具有小的特征的较小比例。 为了实现这一点,激光发射信号的脉冲宽度以600dpi的一个点被控制在16个等级,控制主扫描方向上的实际图像。 当调整垂直和水平线宽时,通过将各向异性图案旋转0°和90°(图5中的S1)来创建贴片数据。 然后,读取器/扫描器(15)读取每个贴片作为密度数据(图5中的S 2)。 获得脉冲宽度,即,通过0°和90°旋转的贴片图案的密度彼此相等的线宽校正值(图5中的S 3)。

    • The present invention provides piezoelectric surface mount devices in which the area of the mounting terminals is reduced, leading to reduction of manufacturing cost. A piezoelectric device comprises a package base (120) including a bottom surface having a long edge and a short edge and a pair of mounting terminals formed on respective short edges of the package base. The pair of mounting terminals are separated by a predetermined longitudinal distance (X3) and are arranged as close as possible to the longitudinal center line of the package base. The predetermined distance is sufficient to prevent electrical short when mounting the piezoelectric device onto the printed substrate. The maximum width (Z2) of each mounting terminal measured in a direction parallel with the short edges of the package base is less than one half the width of the short edge (Z1).
    • 本发明提供了压电表面贴装装置,其中安装端子的面积减小,导致制造成本的降低。 一种压电装置,包括:包装底座(120),包括具有长边缘和短边缘的底表面和形成在封装基座的相应短边缘上的一对安装端子。 一对安装端子以预定的纵向距离(X3)分开,并且尽可能靠近包装基座的纵向中心线。 当将压电元件安装在印刷基板上时,预定距离足以防止电气短路。 在与封装基座的短边缘平行的方向上测量的每个安装端子的最大宽度(Z2)小于短边(Z1)的宽度的一半。
