Title: Automatic gain adjusting system
Inventor: MORI MASAKAZU
IPC: H04B10/2507
Filed: 1980-10-31
Abstract: PURPOSE:To prevent degradation of the SN ratio, by chopping an optical output by a constant frequency in the outside of the analogue signal transmission band to transmit it in a constant level and by detecting a minimum level after photoelectric conversion in the receiving side to control the gain of a receiver so that the level becomes constant. CONSTITUTION:In the transmission side, a laser diode is modulated by an analogue signal, and simultaneously, the signal is chopped through a chopper circuit 2 by a frequency in the outside of the analogue signal transmission band. For the purpose of setting a minimum level P0 of the optical output to a constant value in the laser beam emussion region, the output of a light emitter 7 is received by a light receiver 6, and a minimum potential is detected in a 4 and is so controlled that it becomes a reference potential 8, and an optical signal is transmitted. In the receiving side, the optical signal is received in the 6 and is converted to an electric signal, and a minimum level P1 is detected in the 4 and is compared with the reference potential 8 in a 5, and the output is converted to an optimum value by a DC-DC converter 13 to control the gain automatically in a 10. Thus, the automatic gain control is possible without superposing a pilot signal, and the shot noise due to superposition of the pilot signal is eliminated.

Filed: 1993-06-01
Abstract: PURPOSE:To make processability good by a method wherein decrease of noise- gradually decreasing effect when a thermal load is increased and swelling out of elastomer in a bolting part or the like are removed. CONSTITUTION:A compound 13 layer containing a compressive fiber, elastomer, and a filler is provided between the first metal plate 12 and the second metal plate 15. Since a compound 13 layer containing the compressive fiber, the elastomer, and the filler intervenes between the metal plates 12, 15 instead of an individual elastomer layer, though thermal resistance is increased, an effect for gradually decreasing noise is not reduced. Further, since there is not any drift of the compound 13, the compound 13 does not jut out from between the metal plates 12, 15, a relaxation phenomenon of pressurizing force in drawing is little, and good processability is obtained.
