摘要： PROBLEM TO BE SOLVED: To provide the device which does not require the maintenance of a battery for driving an electrolytic management system by charging the battery with the potential difference generated by the galvanic anode of electrolytic of a galvanic method as electromotive force. SOLUTION: The potential difference generated between a metallic structural body 1 embedded into an electrolyte, such as in the ground, and a metallic body 2 indicating the potential baser than the potential of the metallic structural body 1 is converted to a rectangular wave by turning on/off of an analog switch by an oscillation circuit 16 and is then boosted by a boosting transformer 14. The voltage is subjected to current rectification and is used to charge the charging battery E. The system for managing the condition of the metallic structural body 1 is driven by the charging voltage.

摘要： PROBLEM TO BE SOLVED: To reduce the temp. irregularity of a mold to perform uniform reaction and to form a uniform surface not generating stickiness or gloss irregularity by providing a planar heater to a mold and controlling the temp. in a cavity by the planar heater to perform reactive injection molding. SOLUTION: After a mold apparatus 2 consisting of first and second molds 4, 6 is mounted on the outer periphery of the connection part 36 of pipes 30, 30, the mold apparatus 2 is heated by a planar heater 50 and, at a stage wherein the mold apparatus 2 reaches predetermined temp., a reaction raw soln. is filled into the cavity of the mold apparatus by a mixer. By opening the mold apparatus 2 after reactive injection molding, a protective sleeve composed of the reactive injection molded object wholly covering the vicinity of the periphery of the connection part 36 is obtained. Herein, since the mold apparatus 2 is controlled in temp. by the planar heater 50, the temp. irregularity of the mold apparatus 2 can be reduced over the whole of the cavity and reaction is uniformly performed in the cavity 40.
