摘要： A color image forming system including a photosensitive drum, a charger which charges the photosensitive drum, and a laser scanning unit which is installed below the photosensitive drum and radiates light onto the charged photosensitive drum, to form an electrostatic latent image. The system further includes a plurality of developing units with toner of at least four colors such as yellow, magenta, cyan, and black, arranged at different heights along the outer surface of the photosensitive drum to develop the electrostatic latent image with the toner when a developing roller installed in each of the developing units is maintained at a developing gap with the photosensitive drum. A transfer unit transfers the developed image onto a piece of paper, and a fusing unit is installed above the photosensitive drum and fuses the transferred image onto the piece of paper. The developing units may be arranged in the order of magenta, cyan, yellow, and black.

摘要： The present invention relates to a welding mask for protecting the eyes of a user from a strong welding light during welding. More particularly, the present invention relates to a welding mask which has a face protecting plate made of a transparent material to protect the face of a wearer from the heat and flame of welding and to enable the wearer to see a broad portion of the surrounding area of a welding point, and which has a light shielding part the light shielding rate of which is higher than that of said face protecting plate so as to block the strong welding light generated from the welding point. The welding mask consists of a head part to be worn on the head of a wearer; and a face protecting plate installed at the front portion of said head part so as to cover the entire face of the wearer, wherein the face protecting plate is injection-molded with a transparent synthetic resin material so as to block harmful light and flame generated during welding, wherein a portion of said face protecting plate has a light shielding part formed thicker than the face protecting plate so as to have a light shielding rate higher than that of said face protecting plate.

摘要翻译： 焊接掩模技术领域本发明涉及一种用于在焊接期间保护使用者的眼睛免受强烈焊接的焊接掩模。 更具体地说，本发明涉及一种焊接面罩，其具有由透明材料制成的面保护板，以保护穿用者的脸部不受焊接热和火焰的影响，并使穿戴者能够看到周围区域的大部分 并且其遮光部分的遮光率高于所述防护板的遮光率，以便阻挡从焊接点产生的强焊接光。 焊接面罩由穿戴在穿戴者头部上的头部组成; 以及安装在所述头部前部的面部保护板，以便覆盖穿戴者的整个面部，其中所述面部保护板用透明合成树脂材料注射成型，以阻挡在所述头部部分产生的有害光和火焰 焊接，其中所述面部保护板的一部分具有形成为比所述面部保护板更厚的遮光部，从而具有比所述面部保护板高的遮光率。
