A molded plastic hook fastener component for hook and loop fastening has individual raised bases distributed over a common area, each carrying an individual hook element while a laterally contiguous portion of each raised base raises the lower bound for the loop region beneath the fastener head. After the electrons have passed through the active area of the tube, the electrons strike the collector which, in this case, is a multistage depressed collector. In addition, if the remaining amount of the second liquid contained in the second container is less than a predetermined value, prohibits the switching unit from performing the switching operation of switching from the second communicating state to the first communicating state.
