Filed: 1991-09-03
Abstract: PURPOSE:To provide an optical fiber amplifier with less dependency of a gain and wavelengths thereof on the intensity of an input signal. CONSTITUTION:An optical fiber amplifier comprises optical fibers including, as a core, Er for amplifying 1.55mum wavelength region signal light, an LD for emitting 1.48mum wavelength region excitation light, and an optical coupler for guiding the excitation light from the LD into the optical fibers. Signal light from a signal light source enters the optical fibers through the optical coupler and the excitation light from the LD also enters the optical fibers through the optical coupler. When the excitation light exceeds predetermined intensity, the Er is excited to amplify the signal light. In an illustrated example, use is made of optical fibers cut into a 1m length, which fibers has the optimum lengths of 1m when the signal light is of -40dB. A gain of the amplifier is reduced as the optical fibers become shorter in this length but substantially remains unchanged up to a higher level region of the input signal light.

A correlator 17 calculates the correlative function between the contents of the memories 15 and 16 and outputs the function to the circuit 13, a window function generator 18, and an adder 21. Then the generator 18 generates and outputs the window function to a multiplier 19 and also outputs a window function which is complementary to the window function to a multiplier 20. Then the multipliers 19 and 20 multiply the contents of the memories 15 and 16 by the output of he multiplier 20. Then the multipliers 19 and 20 multiply the contents of the memories 15 and 16 by the output of the generator 18. An adder 21 adds the outputs of the multipliers 19 and 20 while shifting them to positions where the correlative function indicate a large value, and outputs the result to the multiplexer 22. Consequently, the voice which has small discontinuity of the amplified of the waveform and is rich in naturalness can be outputted.

Title: Method for analyzing forming work and medium for recording this execution program
Inventor: MATSUOKA NAOKI
IPC: B21C51/00
Filed: 1999-08-06
Abstract: PROBLEM TO BE SOLVED: To simulate the forging work in a short time by setting plural trace points in the inner part of a work, calculating displacements of the trace points accompanied with the deformation of the work, connecting the trace points after displacement and expressing fiber low lines after deforming the work. SOLUTION: At the initial stage of this analysis, many trace points are set in the inner part of the work. The setting is executed so as to represent the fiber flow lines with straight lines and curved lines connecting the trace points. Then, the displacement accompanied with the deformation of the work is calculated by using the technique of a finite element method on each set trace point. Thus, the fiber flow lines after working can be expressed by connecting the trace pints after deformation. In this way, the development of defects, such as forging defect, dead metal, buckling, is predicted and the tendency of residual stress distribution after forging can be informed.
