Provided is a reconfigurable logic circuit that can effectively use a preposition logic that composes a logic block. The coupling device having a coupling washer between the sockets and connected in rotation with one of the slide-socket and the nut-socket. In a typical implementation the dynamic data structures are used to store information whose organization and values may change responsive to the values of other data stored in the data model. In a state in which the depression and the projection are in a set, a gap is formed between the two pixel electrodes. The night-vision-enhanced images present a night-mode-adapted wavelength spectrum. Furthermore, it levies absolutely no limitations whatsoever on the operation of the transmitter.
