Title: Synchronization system of spread spectrum receiver
Inventor: OGASAWARA MASAYUKI
IPC: H04B1/7073
Filed: 1985-04-22
Abstract: PURPOSE:To shorten the time required for synchronization by generating a pseudo noise code and a code of the same sequence whose clock speed is a half as fast as said code at a reception side, varying the quantities of the step of phase shifts of those two kinds of codes, and selecting the two kinds of codes according to the quantity of the step. CONSTITUTION:While synchronism is not obtained, the pseudo noise code generated by a pseudo noise code generator 9 is timed by a delay flip-flop 6 and a 1/2 frequency divider 7 for a clock signal to obtain the code of the same sequence whose clock speed is a half and this code is selected by a code switch 4. The code is used by a correlator 1 to detect the correlation with a received wave SS. When synchronism is detected, a synchronous detector 5 switches the code switch 4 to the code from the pseudo noise code generator 9 and a phase shift control circuit 8 to a fine step less than one bit. Consequently, the time for synchronous detection is shortened.

Title: Non-contact method and apparatus for resistence provided secondary circuit of transformer
Inventor: DETOREFU KAMINSUKII
IPC: B60R21/16
Filed: 1989-04-07
Abstract: PURPOSE: To measure the resistance of a resistor in the secondary circuit of a transformer by energizing an oscillation circuit connected with the resistor on the secondary of transformer from the primary thereof, cutting off the energizing signal and then returning an attenuating energizing response to the primary. CONSTITUTION: A secondary LCR series oscillation circuit 4 is energized with a short duration current pulse, e.g. limited number of sinusoidal oscillation, through a transformer 2. Since the transformer 2 has primary 6 closed with a high resistor, it provides only the function of inductance connected in series with a coil L. Attenuated oscillation takes place in the circuit 4 and the attenuation depends not on the coupling with the transformer 2 but on the quantities R' and L'. An equivalent circuit of attenuating oscillation can be obtained on the primary. A time constant τ=2L'/R' is a measure of secondary resistance which must be obtained irrespectively of the coupling characteristics of transformer 2. Subsequently, peak value U0 of response is determined and the oscillation is counted until a predetermined threshold U0 /m, e.g. U0 /2, is reached.  Finally, envelope of response is formed and the interval between two predetermined limits is measured.
