Title: Code synchronization capture circuit for spread spectrum signal
Inventor: SAITO SHIGETOSHI
IPC: H04B1/7075
Filed: 1999-03-01
Abstract: PROBLEM TO BE SOLVED: To attain sure code synchronization capture at high-speed by maximally utilizing information obtained from each of a plurality of antennas, in spite of a simple configuration where only one matched filter is provided. SOLUTION: An adder 9 of this code synchronization capture circuit sums a reception signal of a system of an antenna 1-1, without phase shift and reception signal of a system of an antenna 1-2 with a delay Td by a delay device 11. A matched filter 5 uses a prescribed synchronization spread code to apply inverse spread processing to the received signal obtained, by summing the two systems of the received signals by this adder 9. Then a power calculation section 6, a synchronization adder section 7 and a synchronization section 12 apply synchronization acquisition of the spread code, on the basis of a generated state of a peak of power in the inverse spread output by the matched filter 5.

Title: Engine control device
Inventor: NIITSUMA SHIGETO
IPC: F02D43/00
Filed: 1985-03-19
Abstract: PURPOSE:To continually hold good drivability, by providing a delay characteristic to a switching control of an ignition number and holding the time conformity always between a change of air-fuel ratio and the switching of the ignition number. CONSTITUTION:An automobile is driven to be accelerated by opening a throttle valve, and if an intake negative pressure approaches the atmospheric pressure, a control device, closing a vacuum switch 2 at a predetermined negative pressure or less, outputs a clamp control signal from a control unit 1 to a feedback control fuel supply unit 4. While a switching signal of two point one point ignition is also output, but here the control device, placing a vacuum switch 7 in an off-condition due to the delay action by a delay valve 5 and a surge tank 6, leaves a distributor 3 as it is in the two point ignition, and air-fuel ratio starts to change into a rich side. And after a predetermined delay time, the control device, turning on the switch 7 and inputting the switching signal of two point one point ignition to the distributor 3, transfers it to the one point ignition. In this way, the control device, preventing a transient condition from being generated in an engine in its acceleration or the like, can always hold good drivability.

Filed: 1985-03-18
Abstract: PURPOSE:To achieve a higher resolution, by providing a control means which turns a (n+1)th code plate by a specified angle each time an n-th code plate makes a turn to output a code pattern read out as coding signal according to the angle of rotation of an input shaft to enable the detection of the angle of rotation exceeding 360 deg.C. CONSTITUTION:When the rotation of a load is transmitted through an input shaft 1 and a first stage code plate C1 makes a turn positively, a pulse motor PM turns a second stage code plate C2 by minimum division angle positively. Thereafter, each time the code plate C1 makes a turn positively, the motor PM turns the code plate C2 by minimum division angle positively. The same action is done in the reverse way. Then, the code pattern corresponding to the angle of rotation from the reference positions of the code plates C1 and C2 are read out by detector sections S1 and S2 and outputted from a control circuit 3 as coding signal corresponding to the angle of rotation of the input shaft 1. In addition, the rotatable range of the input shaft 1 can be extended by increasing the number of stages thereby enabling a higher resolution.
