Title: Spread spectrum signal processing circuit and synchronizing method for spreading signal
Inventor: YASUKAWA KAZUYUKI
IPC: H04B1/709
Filed: 1995-10-31
Abstract: PROBLEM TO BE SOLVED: To provide an inexpensive active correlating system, with which synchronism can be economically established at high speed, by providing a switching control means and a synchronizing detecting means and simultaneously and parallelly searching synchronism at plural correlators. SOLUTION: When establishing synchronism with a received spread spectrum signal DSS, correlators 11-1n divide one code length of a PN code pattern into (n) parts and prepare a PN code by shifting a phase for a 1/n cycle. When a synchronizing detecting means 4 detects synchronism from the output of any correlator, while defining the PN code of that correlator as a reference phase, a switching control means 5 inputs that PN code to the correlator 11 as pn1, and a signal d1 of correlation with a spread signal DSS is outputted through an information demodulator 8. Besides, with this signal as a reference, the outputs of the other correlators are defined as d2-n and until synchronism is detected, it is simultaneously and parallelly searched by a phase locked loop circuit 2 composed of a subtracter 21, loop filter 22, voltage controlled oscillator 23 and spreading code generator 3.  Thus, synchronism can be economically established at high speed.

Abstract: PURPOSE:To prevent the reduction in torque of a two-cycle engine and the like by controlling the quantity of corrective air bleed by use of imbalance of negative pressure generated accompanied with the opening/closing of a throttle valve thereby decreasing the quantity of bleed air mixed with main fuel in case of more than the medium quantity required by the engine. CONSTITUTION:Negative pressure in a venturi 3 is low when a throttle valve 4 is opened small, and as negative pressure acting on respective ports 26a and 27a opened at the high and low positions of the narrowest section 3a which are located symmetrically, is identical, a control valve 15 is opened wide by means of a spring (25) action. Then the quantity of suction air will be medium as the opening of the throttle valve 4 is increased, as negative pressure acting on the port 26a at the high position becomes high, the difference in pressure is generated between two negative pressure chambers 21 and 23 for moving a diaphragm 22 to No.1 negative pressure chamber 21 so as to make the opening of the control valve 15 small. As a result, as the quantity of corrective air bleed passing through a passage 14 is decreased, main fuel sucked out of a main nozzle 8a is increased.
