A fuel hose wherein an electrically conductive fluororesin is used as an inner layer, and the inside surface thereof is smooth even when it is molded at a high speed, is provided. By introducing a second catalyst capable of producing a powdery polymer into the polymerization system during production of the sticky polymers, these normally sticky, tenacious polymers are rendered into a form which may be processed using conventional means and equipment. The device facilitates deprogramming and releasing of the upper and lower jaw muscles. Areas of the photomask that have a lower structural density and therefore have a higher light intensity can be formed to have a thicker transmission control layer as compared to areas which have a higher structural density and which already have a lower light intensity. Namely, the piezoelectric material 3 is formed so as to contain Pb excessively and the excess Pb atoms are activated to be Pb4 during formation of the piezoelectric material 3 and then introduced into the B site. Since information obtainable in the transponder device is only the relative phase of the signal light with reference to the phase of the local light, and includes fluctuations corresponding to an antisqueezed component of the signal light, even if the information in the transponder device is eavesdropped on, the information cannot be decoded easily.
