A tobacco product is formed by rolling a sheet of material supplied by a roll or rolls andor homogenized sheet tobacco about a slit mandrel to form a shaped tube. The photoreactive polymer exhibits excellent thermal stability since it includes a multi-cyclicmulticyclic compound having a high glass transition temperature at as its main chain. For the first pair of antennas, there is used a signal subjected to encoding with a code-division-multiple-access code and subjected to spreading with a spreading code, and, likewise, for the second pair or pairs of antennas there are used signals subjected to encoding with respective code-division-multiple-access code and subjected to spreading with a respective spreading code. The second PMOS transistor is coupled between the first voltage terminal and a second node. The predetermined number of sub-carrier signals is determined in accordance with one of a plurality of operating modes and the input data symbols are divided into first sets of input data symbols and second sets of input data symbols. The capaciflective sensor senses the presence of objects a predetermined distance from the vehicle port.
