Vessels without Leakage when Holes and Cracks Appear

This paper proposes a method for obtaining the vessel, such that no fluid is leaked when holes or cracks occur, because the broken part is repaired auto- matically by its self-repairing mechanism. The self-repairing unit （sealant layer） is consisting of two rubber sheets with quilting processed. Polymer particles, which expand their volume in contact with water, produce the force for selfrepairing. This article first discusses a method for making the vessel, then the method is applied to a tire with l...

Development of Leak-Free Vessels against Holes and Cracks

A new type taping for a water storage vessel or piping is presented, in which water leakage is isolated automatically by its self-repairing mechanism against holes. The self-repairing unit (sealant layer) is consisting of three pieces of net with lattices inside. Polymer particles, which expand their volume with water, is used for having self-repairing forces. In ordinary tapes, water leaks along the boundary between the tape and the vessel. In order to retain the leak isolation force, this article fi...

Leak Isolation Self-Repairing Tape for a Water Storage Vessel and Piping Against Holes

A new robot is presented which is able to climb on a perpendicular piping with branches and moves on the ceiling in the piping. The robot is a crawler type whose crawler has made of magnetic tips. The magnetic tips of the robot adhere to the piping made of iron due to magnetic forces. When the adhesive force is larger than the gravity force of the robot, a connection between the robot and the ceiling can be maintained. That is, the inspection robot in piping can move freely in solid piping of all shap...
