A gate locking assembly includes an anchor shaft that has rectilinear-shaped first and second sections orthogonally registered with each other. The birefringent layer is formed on the base by: coating a material of the birefringent layer on the base so as to form a coating film; stretchingshrinking the base so as to stretchshrink the coating film; and solidifying the material of the coating film. The leak detection system includes a means for indicating whether the first valve is maintained in a closed position or an open position, a means for indicating whether the second valve is maintained in a closed position or an open position, and a pressure change detector within the intermediate fluid flow passageway. First contacts are formed on the substrate at a side of the first memory array and arranged along the second direction.
