Title: Optical switch and its quenching ratio improving method
Inventor: NAKAMURA SHIGERU
IPC: G02F1/35
Filed: 1997-10-20
Abstract: PROBLEM TO BE SOLVED: To obtain a sufficiently high quenching ratio even though a nonlinear optical waveguide having the dependency to nonlinear phase shift signal optical polarization is used by constituting a nonlinear refractive index variation expressing section of two nonlinear optical waveguides. SOLUTION: The nonlinear refractive index variation expressing section of the optical switch is constituted of two nonlinear optical waveguides 1 and 3. The signal light beams, which are propagated in a first nonlinear optical waveguide with a TE polarization condition, are propagated in a TE polarization state in a second nonlinear waveguide 3. Conversely, the signal light beams, which are propagated in the waveguide 1 with a TM polarization condition, are propagated in the waveguide 3 in a TE polarization state. In other words, the received nonlinear phase shift of the signal light beams becomes independent to the signal beam polarization by the propagation in the waveguides 1 and 3.  Thus, the linearly polarized components, which are mutually orthogonal, receive a π radian nonlinear phase shift, the signal light beams, which are outputted immediately after the completion of a switching operation, completely return to an initial condition and the quenching ratio is improved.

Abstract: PURPOSE:To correct the feed speed in grinding on the real time basis so that the optimum grind feed speed is generated irrespective of the degree of wear of a grinding wheel by furnishing a fuzzy reasoning means which uses, as the input variable, the deviation of the current diameter measuring value of a work from the corresponding theoretical value and the varying amount of deviation on the time axis and which uses, as the output variable, a value changing the grind feed speed. CONSTITUTION:The theoretical value for the current diameter of a work W to be reasoned from the current position of a grinding wheel sensed by a current position sensing means, and the deviation of the corresponding measurement on the work W from this theoretical value is computed by a deviation computing means 31. A fuzzy reasoning means uses this deviation and its varying amount on the time axis as the input variable and uses the value to change the grind feed speed as the output variable, and on the basis of the value according to the reasoning by this fuzzy means, the current grind feed speed is altered by the speed control means 31. This permits securing the optimum deviation irrespective of the wear of the grinding wheel, which leads to prevention of the processing accuracy from dropping.
