A method and apparatus for direct sequence spread spectrum communication having low complexity. The sensor chip includes a strain gage for outputting an electrical signal according to distortion of the diaphragm caused by pressure to be measured. A motor is coupled to the drum for rotating the drum within the cabinet. The method also includes scheduling the primary and secondary queue heads in immediately subsequent frames. The polycarbonate resin composition of this invention possesses superior flame resistance without losing shock resistance and moldability, and as it does not contain halogen fire retardants manufactured from chlorine and bromine compounds, there is no concern about generation of gases containing halogen from the fire retardant during combustion. In order to stabilize the tool during cutting the cutting edges comprise inner cutting edges laying on a first surface of revolution which is in the first direction higher at a larger diameter and lower at a smaller diameter.
