Title: Variable power driving control device
Inventor: KISHIMOTO TADAO
IPC: G03G15/041
Filed: 1984-09-03
Abstract: PURPOSE:To obtain a variable power driving control device able to shorten the moving time of a lens and a mirror even if a stepping motor is used by switching the driving frequency of the stepping motor in accordance with magni fication. CONSTITUTION:A copying machine enabled to modify its magnification from 0.61%-1.41% converts the driving frequency of the stepping motor 8 through a driver 7 when a command is inputted to a microprocessor 6. When the stepping motor 8 is switched by 100pps for a range of 0.61%-0.81% and by 300pps for a range of 0.81%-1.41%, a time required for the movement over the whole area is shortened by 8sec as compared with the driving of the whole area by 100pps. Since the driving frequency is reduced at high load torque and increased at low load torque, the moving time of the lens 2 and the mirrors, 4, 5 can be shortened.

Filed: 1996-06-25
Abstract: PROBLEM TO BE SOLVED: To conduct synchronization processing in a short time. SOLUTION: A signal from each satellite is supplied to receiving processing circuits 5-1-5-4 of channels 1-4, processing of inverse spread spectrum and PSK demodulation is conducted, navigation messages DT1-DT4 from first - fourth satellites are obtained, then sent to a CPU 11. In the CPU 11, position measurement is conducted by utilizing the time of each navigation message and orbit data. In the CPU 11, the synchronous state of each channel is judged in the level of inversely spread spectrum output (relative output) of a signal from the satellite, and synchronous process is conducted in off synchronous state. In the synchronous process, although time base data more than bit number is required after reaching synchronous (bit demodulation) state, when other channel (i) synchronous-processed exists in synchronous process of a channel (j), time base data more than bit number is used.  Obtaining the time axis data more than bit number by detecting preample is unnecessary, and synchronous process can be conducted in a short time.
