Title: Manufacture of optical fiber amplifier
Inventor: KINOSHITA SUSUMU
IPC: H01S3/10
Filed: 1992-02-18
Abstract: PURPOSE:To optimize the length of a doping fiber by cutting an optical fiber in a position where the intensity of a naturally radiating light is equal to a predetermined value. CONSTITUTION:A light intensity detector 10 is so provided at a linear part of a doping fiber 6 as to be scanned in a longitudinal direction of the fiber 6. The detector 10 is driven along the linear part of the fiber 6 to measure the intensity of a naturally radiating light emitted sideways from the fiber 6. In order to obtain the optimum length of the doping fiber, the power of the spontaneously emitted light at a point of starting to attenuate the signal light is previously measured, or the value of the radiating light power near the output end in the case of the optimum length is obtained by a theoretical calculation. When the measured value becomes equal to the value, the fiber 6 is cut to be of the optimum length. Thus, an optical fiber amplifier having a high gain efficiency can be manufactured.

Abstract: PURPOSE:To provide the output control circuit of the semiconductor device keeping low noise and high speed performance regardless of a change in ambient temperature. CONSTITUTION:When a level of a binary signal D1 changes from 1 to 0, only a transistor(TR) Q2 is turned on and a load capacitor C connecting to an output terminal 1 starts discharging. When the ambient temperature is low and a level of a delay control signal S3 is at 0, TRs Q5, Q7 are turned off and TRs Q6, Q8 are turned on. As a result, the TRQ4 is turned on with a delay time of a delay circuit 2 after the TRQ2 and the capacitor C is really discharged. On the other hand, when the ambient temperature is high and the delay control signal S3 is at logical 1, the TRs Q6, Q8 are turned off and the TRs Q5, Q7 are turned on. As a result, the TRQ4 is turned on with a delay time of a delay circuit 3 after the TRQ2 and the capacitor C is really discharged. The delay time of the delay circuit 2 is set longer than the delay time of the delay circuit 3.

IPC: H04N5/93
Filed: 1979-03-15
Abstract: PURPOSE:To obtain a stable reproduced picture of a video signal which never changes in level, by correcting an error of the number of horizontal scanning lines in a vertical period by combining delay signals. CONSTITUTION:A time-axis correcting unit is composed of delay elements 17-20 with delay time of 0.5H, output change-over circuit 21, etc. In this constitution, CCD's are used as elements 17-20 to supply an undelayed signal to input terminal 15 and outputs 23-26 delayed by 0.5H, 1H and 2H are extracted from output terminal 16 through the switching of circuit 21 with the time axis corrected. Namely, 1H-delayed output 24 is generated while reproduction is put into effect by head A and undelayed output 22 is generated while the reproduction is carried out by head B, so that an error of the number of H's in the vertical period will be a deflection of approximate 1H. Further, when the combinational output of delay elements is used, the time axis correction is made before an addition signal of a FM signal and low-frequency conversion chrominance signal is separated, so that flicker on a screen can be eliminated.
