Abstract: A receiving device is provided with a DLL circuit of a reduced scale. An inverse spreading processing to ensure the synchronism with a received signal and a processing to inversely spread original data in the received signal are performed by a time-sharing operation using one inverse spreading circuit and one integrator. During a period in which synchronous data for detecting a slot duration included in the received signal is received, the synchronous data is alternately inversely spread by an early code and a late code and sample-hold circuits alternately sample and hold the integrated output. Further, based on the difference (error signal) between sample-hold signals, the early code, the late code and a reference code outputted from a code sequence generator are synchronized with the received signal.

Abstract: A navigation system of a hybrid car retrieves a route to detect whether any restricted area forbidden for automobiles that emit exhaust gases is on the route or not. Before the hybrid car arrives at the restricted area, an electric motor is driven by a gasoline engine portion to charge a battery portion. After the hybrid car arrives at the restricted area, only the electric motor is operated by electric power of the battery portion so that the hybrid car can pass through the restricted area. As a result, the hybrid car can arrive at a destination by the shortest distance without bypassing the restricted area, and the environment of the restricted area can be protected because the gasoline engine portion is not operated in the restricted area.
