This invention is directed to an improvement in acrylic based adhesives that are particularly suited for use in the application of paper and plastic labels onto glass surfaces, such as in bottle labeling. Or, the control unit controls driving for the second lens unit to generate the information, and performs weighting based on detection results from the distance detecting unit relating to driving control. A first connection terminal electrically is connected to the core circuit. In the preferred embodiments, at least one anchor structure is movable along the elongate tensile member to assist with adjusting a tendon segment to an appropriate repair position and the anchor structure or structures are then lockable onto the elongate tensile member to assist with affixing the tendon at the repair position.
