摘要： PURPOSE:To stabilize the butt state of optical fibers by butting and connecting the respective optical fibers in a tubular connector mounted in a connector mounting groove, mounting the optical fiber parts on the outside of the tubular connector in the optical fiber mounting grooves and the fiber parts in the fiber mounting grooves and solidifying these parts by an adhesive agent. CONSTITUTION:The optical fibers 2A, 2B of multiple optical fibers 1A, 1B are inserted into the tubular connector 3 from both sides and are butted and connected therein. The tubular connector 3 is mounted into the connector mounting groove 7 of a base plate 4. The parts of the optical fibers 2A, 2B on the outside of the connector 3 are mounted in the fiber mounting grooves 8A, 8B and the multiple optical fibers 1A, 1B are mounted in the fiber mounting grooves 9A, 9B respectively. The adhesive agent 5 is applied on the substrate 4 so as to embed the connector 3 and the optical fibers 2A, 2B. A cap plate 6 is adhered and fixed thereon. The butt state is stabilized in this way and the generation of the fluctuation in the connection state is substantially obviated. The integral juncture having the high reliability is thus constituted.

摘要： PROBLEM TO BE SOLVED: To provide a leakage and flooding detecting device and method in which a location of an image pick-up device is not limited in a narrow range and misjudgment is not likely to occur, by providing a container with an inflow inlet for liquid to monitor and a mark body actuated by a detecting body which expands and deforms by bringing it into contact with the liquid to monitor. SOLUTION: A liquid leakage and flood detecting device is structured by providing a detecting body 3 in a cylindrical container 2 and attaching to an upper part of the container 2 a mark body 4 actuated by the detecting body 3 which expands and deforms by bringing it into contact with liquid to monitor. Where in the container 2 an inflow inlet is provided can be determined by predicting an infiltrating passage of the liquid to monitor. If flooded water is predicted to infiltrate from a lower part of the container, the inflow inlet is provided by making the bottom or the lower side of the container meshy, or forming a hole on the bottom of the container. If the liquid to monitor is predicted to infiltrate from the upper part of the container, the inflow inlet is provided by forming a hole in the mark body 4. Depending on a place for the flood detecting device, any of the above can be used.
