Title: Synchronization acquisition method in frequency hopping modulation spread spectrum system
Inventor: IMAMURA KAZUMASA
IPC: H04B1/713
Filed: 1994-05-30
Abstract: PURPOSE:To attain high speed synchronization acquisition by providing a transmission means to which a specific hopping frequency is allocated and a reception means conducting synchronization acquisition by selecting a hopping frequency in response to a prescribed spread code series after acquiring the specific hopping frequency to the system. CONSTITUTION:In the transmitter-receiver of the frequency hopping modulation spread spectrum system, a spread code generating circuit 7 generating a frequency hopping modulation spread code series allocates a specific hopping frequency to plural codes from the head of each spread code series and provides an output. Furthermore, the receiver side awaits the arrival of the specific hopping frequency and acquires the specific hopping frequency and selects a hopping frequency corresponding to a prescribed spread code series to acquire synchronization and to receive data. Thus, tentative acquisition is conducted at a high speed with a conventional hardware configuration because the hopping frequency is shifted within the range of the changeover performance of a frequency synthesizer.

Filed: 1984-06-08
Abstract: PURPOSE:To improve the combustion stability and the exhaust purification effect of engine by making the combustion mixture gas thicker than the theoretical air- fuel ratio while feedback controlling the exhaust gas flowed to three element catalyst correctly to the theoretical air-fuel ratio. CONSTITUTION:When secondary air control means 6b is at the temperature lower than setting level, the block valve 13 of secondary air path 11 is opened by means of the output from a sensor 15 for detecting the engine temperature to lead secondary air into the exhaust gas. When feeding secondary air into the exhaust gas during or immediately after warming of engine, it is decided from the output of an exhaust sensor 5 that the mixture gas in the intake path 2 will be thinner in appearance than the theoretical air-fuel ratio to increment the fuel through air-fuel ratio control means 6a thus to make thick the combustion mixture gas. Since combustion gas composed of secondary air and thick mixture gas wil flow to the three element catalyst 4, similar effect with reaction of combustion exhaust having approximately theoretical air-fuel ratio is achieved. Consequently, combustion under said operating region is stabilized while the exhaust purification effect is improved.
