A zero stripper accepts individual bit sequences marked off by a break codes in a bit stream, deletes any leading \u201c0\u201d bits from such bit sequences so as to form a zero-stripped datum segment, counts the number of bits in each resultant datum segment, and then concatenates each such datum segment with the bit count of that datum segment into the code formnnnndddddd. Specifically, the substrate tube is placed within a metal cladding tube made of platinum, gold, tantalum, tungsten, platinum-iridium, palladium, or nickel-titanium, preferably with an interference fit therebetween. The constituent parts of the box are connected using male elements which are solidly connected to the side walls and female elements which are disposed on the base. A fixed high logic input is coupled to a first input of a row driver logic device associated with a local out of range address. Thus, an easy-to-monitor panel with high luminous efficacy is obtained wherein the addressing and maintenance functions are separate. The sealing portion includes a first component and a second component that are adjustable relative to each other in order to define an overall static dimension of the sealing portion.
