    摘要: The present invention is intended to provide an image processing apparatus capable of two-color output representation in high accuracy even with a full-colored original. A color original is entered by an input means for prescan, a density distribution with respect to a hue is obtained for each electric signal of color image information, and a characteristic point of the color original image is obtained from the result of the density distribution. The two-color separation means separates a full-colored original to two colors free from the same color representation according to the information of the characteristic point obtained.

    摘要: A data input system including electronic paper and a stylus writing device is disclosed. The electronic paper includes a transparent display substrate on which a number of optically readable code patterns have been formed, the optically readable code patterns representing positional information on a display surface, a rear surface substrate opposing the display substrate, and coloring particles that are enclosed between the display substrate and the rear surface substrate and that are movable by applying an electric or a magnetic field. The electronic paper displays an image due to motion of the particle. The stylus writing device includes a writing head provided at the end of the stylus for writing the image by applying an electric or a magnetic field to the electronic paper by contact and includes an optical reading device for optically reading the code patterns formed on the display surface where the end of the stylus contacts.

    摘要: A laser arc hybrid welding head and method which can form satisfactory beads at high speed are provided. A laser arc hybrid welding head (1) for welding a base material (W), which comprises aluminum steel sheets, by performing laser light irradiation and arc discharge, thereby combining laser welding and arc welding, splits inputted laser light (L0) into two beams, i.e., split laser light beams (L2a and L2b), then irradiates the base material (W) with the split laser light beams (L2a, L2b) while focusing these beams (L2a, L2b) on the base material (W), and also performs coaxial welding by generating an arc (A) from an arc electrode (20) disposed coaxially with the optical axis of the split laser light beams (L2a, L2b). Further, the transfer mode of a welding droplet from the arc electrode (20) is rendered spray transfer.
