A seal for an ink-discharge port on a printer ink cartridge, according to various embodiments of the present invention, is disclosed. The implantable device includes a constant flow pump and a flow rate that may be altered by commands received from the external control device. in a tubular reactor with one or more reaction zones, which is equipped with cooling jackets for cooling the tubular reactor with a cooling medium, comprising a step of measuring as process parameters the temperature profile and the pressure of the reaction medium and the flow and temperature profile of the cooling medium along the reactor. The short detection unit may be configured to perform a short detection to detect whether the display panel is shorted based on a short detection reference that is adjusted according to an operation mode of the display panel. A pair of outer tabs is connected to distal ends of each of the second flaps and are foldable about a corner crease such that the outer tabs of the next adjacent second flaps abut when folded.
