  • the estimation of the self healing Repair Technology for cracked underground structures on the urban highway system

    Co-Authors: Chien-wen Huang, Jun Hui Park, Yuuji Konishi, Norihiko Ogura, Koichiro Sato, Hiroshi Nishi, Ryo Ishikawa, Toshiharu Kishi
    Abstract:

    During the service life, the durability of a concrete structure is always an essential issue in civil engineering. Past researches indicated that the presence of a crack exacerbates the rate of carbonation progress in a concrete structures, leading to the corrosion of embedded rebar or tendons. Such phenomenon may alter the engineering properties, structural capacity, and deteriorated levels, which in turn affect the durability, water leakage, water-tightness of a concrete structure, as well as air tightness to withstand challenges in service. In general, the preferred countermeasure of a large scale underground concrete structure to prevent water passing through construction is waterproof sheet membrane. However, the remedial action to be taken to prevent leakage into crack areas are often inaccessible. In addition, Japan society entered the age of declining birthrates and working age population over a decade, which implied the capital for the infrastructure maintenance and renewal has dramatically declined. Therefore, an appropriate self-healing material for Repair, maintenance and rehabilitation tasks is significant undertaking.

In this paper, to assess the efficiency of self-healing material, the advanced technique which considers simple and less time consuming of Repairing tasks was applied on underground structures under the water leakage condition for the urban highway system. By examining the monitored data for healed structures, the results revealed that the crack healing was activated and accurately closed water leakage cracks after Repairing.

  • Research on the mask micro-transparent defect Repair assisted with UV laser
    2011 IEEE International Conference on Mechatronics and Automation, 2011
    Co-Authors: Min Wang, Jimin Chen
    Abstract:

    Photo-mask is a pivotal tool in photolithography process. The quality of the photo-mask has much effect on the figures of integrate circuit. With the fast development of the micro-electronics Technology and laser application Technology, in some advanced countries, the research on the photo-mask defect Repair Technology, especially on the clear defect laser Repair Technology has been strengthened. This paper focuses on this application. By use of the 355nm UV laser the chromium powder between two piece of ultra-white glass has been affected to coat thin film on the glass under normal conditions. We analyze the parameters of the Cr film by experiential methods and also the morphology, thickness, surface smoothness, components of the experiential results. The result is that Cr film with uniform thickness, good adhesion and stable components can be obtained in specific laser parameters. Finally the conclusion is that this method can be used to Repair the clear defect on the Cr-mask.
