An orbiting spacecraft payload delivery system for delivering a payload to an orbiting spacecraft, the system comprising a launch vehicle, a mobile launcher, and an orbiting reusable space tug. Byte substitution operation and inverse byte substitution operation are to be combined. The capacitive structures each include three capacitive plates arranged to have two plates located in an upper layer and one plate located in a lower layer. The base is provided with an outlet means which communicates with the inlet port and an inlet conduit connecting the main flow passage with the outlet means. The profile data is information defined as a data string of a format determined by protocols that are different for each of the control devices, the profile data not being software for performing data exchange. The interface circuit includes emulation logic for emulating at least one memory circuit of a second number.
