A receptacle for maintaining the temperature of its contents. The support member 3 is connected, on the one hand, to an external mounting structure 30 and, via base points 2, to the gear elements 1. The output clock time data has a value corresponding to a phase of a virtual output clock generated by dividing the operation clock in accordance with the time resolution. The dielectric material also serves as the dielectric of an additional capacitive component having the active electrode and the grounded reflective metal backplane as plates. The invention is also a smart mail box which includes a processor for performing at least one of a variety of mail-related and communications functions. The process results in substantially complete or complete hydrogen utilization and substantially contamination-free or contamination-free hydrogen.
