Provided is a camera capable of achieving a simplification of an assembly process thereof. Moreover, the slice position to be reconstructed is divided into plural blocks, the areas of the projection image corresponding thereto are cut out, and the processing unit is set for each block as local data of each block, and the set unit is allocated with respect to each operation, whereby parallel processes are executed. The cyclonic filter also includes a first baffle element positioned in the chamber, the first baffle element having at least one inlet. Advantageously, the techniques can be used to enhance the utilization of existing multicarrier RF transmitters, including those found in third generation cellular base stations. The charge unit electrically connects to the cord set sub-assembly while the connectors of the charge unit and the cord set sub-assembly are connected to one another to thereby form a cord set.
