Filed: 1995-07-21
Abstract: PROBLEM TO BE SOLVED: To quickly, simply and surely repair a metallic tube without changing its size and to prevent the characteristics of single or plural transmission fibers stored in the tube from being deteriorated by slightly bending a part of the tube including a defect, mechanically applying tension to the tube and executing spot welding by almost minimum heat energy required for welding. SOLUTION: A repairment station 10 includes a spot welding laser 11 and an adjusting unit 12 for a tube 5 opposed to the laser 11. The unit 12 is mainly provided with a bending means 14 for the tube 5 opposed to the laser 11 and two means 15, 16 for guiding the tube 5 on the means 14 and applying tension to the tube 5 and a repairing route is formed among the three means 14 to 16. In the case of repairing a defect, heat energy in each spot is adjusted to an almost minimum value necessary for welding.

Abstract: PURPOSE:To obtain a desired ration of density between an original image and its copy with ensuring and edge effect with a line image and without lowering the field intensity of a solid image prints even with use of a single component developer, by providing a number of microelectrodes to a toner carrier member. CONSTITUTION:A number of microelectrodes 6 made of iron, etc. are provided  to a conductive supporter 5 as the development electrodes of a toner carrier  component 4. In such constitution, the electrostatic latent images L1 and L2 of a  line image and a solid image prints are formed at a photosensitive layer 3 with  the positive electric charge. In such case, the line of electric force going toward  the texture part of the layer 3 from the image L1 increases greatly to produce a remarkable edge effect in the case of the line image owing to the existence of the electrodes 6. While in the case of the solid image prints, the field density is not virtually reduced unlike the conventional method. As a result, an ideal state of a density ratio is obtained between an original image and its copy for both the line image and the solid image prints.
