The present invention relates to a poly-superparamagnetic nanoparticle complex including a biodegradable and thermosensitive poly and a iron oxide -series ferrite superparamagnetic nanoparticle, a preparation method, and uses of carrying a physiologically-active material, a bio-material and a biomaterial for cancer hyperthermia. The clock generator changes the frequency of the clock signal by a frequency control signal during a time when the logic circuit is operating, and the speed controller controls the operating speed of the logic circuit in accordance with a change in the clock signal. A mobile terminal is also described. The invention is based on the discovery that leadframes are used in the prior art to bridge the distances between predetermined contact separations, offering the possibility of producing, in one stamped part, strip conductors which have different geometries.
