IPC: H04B10/61
Filed: 1989-02-28
Abstract: PURPOSE:To prevent the deterioration in a transmission quality by feeding back a noise component from a reception side and using an LD driving control means at a transmission side and applying the driving control of a laser diode at all times, thereby reducing the noise component. CONSTITUTION:A transmission section 1 gives a modulation signal such as a video signal to a laser diode(LD) to apply optical modulation and an obtained optical signal is sent to a reception section 3 via an optical fiber cable 2. The reception section 3 demodulates the received optical signal and the resulting signal is branched into a main path and a noise extraction section 5 in a prescribed ratio with a branching device 4 composed of a transformer or the like. The extracted noise component controls the stimulation of the LD of an electric/ optic converter 6. The optical signal outputted from the electric/optic converter 6 is given to the optic/electric converter 8 of a station provided with the transmission section 1 via an optical fiber cable 7. A control section 9 controls the LD1 so as to obtain a minimum C/N.

Title: Shake correcting device and interchangeable lens
Inventor: IMURA YOSHIO
IPC: G03B5/00
Filed: 1998-03-02
Abstract: PROBLEM TO BE SOLVED: To provide a shake correcting device correcting a shake for a long time and also accurately correcting the shake. SOLUTION: A shake correcting device changes a shake correction control in accordance with a passing time after receiving a shake correction start signal or an exposure start signal. A control coefficient α1 is a coefficient for driving from the center of a correction range to the periphery of that, and the control coefficient β1 is the coefficient for the driving from the periphery to the center. The shake correcting device sets the control coefficients α1 and β1 to be 1 within first five seconds and the shake is faithfully corrected to shake speed and shake amount detected. On the other hand, the shake correction device controls so as to drive a shake correction lens in the vicinity of the center of the correction range by setting the control coefficient β1 to be larger than that α1 after passing five seconds.  Thus, the shake correction lens is prevented from reaching the limit of the correction range, so that the shake is corrected for the long time.
