    • In the production of a tunneling probe tip having a sharp point by utilizing electropolishing, the present invention has enabled the production of a platinum tunneling probe tip always produceable in an identical conical form having high point sharpness without scattering in the shape caused by the anisotropy of crystal face with respect to the rate of polishing during polishing of a platinum material through adoption of a two-stage polishing process, which comprises subjecting a platinum tunneling probe tip material to a primary polishing for primary shaping of the tunneling probe tip material into a tunneling probe tip form, and then subjecting the shaped material to a secondary polishing for sharpening of the point with a mixed acid comprising sulfuric acid, nitric acid, and phosphoric acid.

    • The optical transmission equipment includes: a demultiplexer for demultiplexing a transmitted wavelength-multiplexed optical signal to first and second optical signals; a first variable dispersion compensation unit; a second variable dispersion compensation unit; a first error detector; a second error detector; and a dispersion compensation control unit for controlling dispersion compensation amounts of the first and second variable dispersion compensation units based on the detection result of the first or second error detector. Upon detection of a signal error in the first optical signal, the first variable dispersion compensation unit is controlled to change from a first compensation amount to a third compensation amount, and the second variable dispersion compensation unit is controlled to change from a second compensation amount to a fourth compensation amount.
