摘要： In a network computer system wherein the type of keyboard at a managing terminal is different from the type of keyboard at a managed terminal, keyboard scan code data from the keyboard at the managing terminal is first converted to virtual scan code data. Next, the virtual scan code data is converted to keyboard scan code data that is compatible with the keyboard at the managed terminal. This conversion, which uses two conversion tables that are selected from a plurality of conversion tables by detecting the different types of keyboards at the managing and managed terminals, permits the keyboard at the managing terminal to be of a different type than that at the managed terminal.

摘要： Detection of an optical pulse position uses an optical pulse string with a determined repetitive ratio and an electric clock signal with a same frequency as the repetitive ratio of the optical pulse string. A phase of the electric clock signal oscillator is shifted and supplied to an optical modulator. The optical modulator modulates the optical pulse string based on the electric clock signal and outputs a modulated optical signal. A photo detector converts the modulated optical signal output from the optical modulator to an electric signal. The phase shift amount of the electric clock signal is controlled to maximize an output from the photo detector. Additionally, a dither signal may be used in the control of the phase shift, more than the optical modulator may be employed, and/or more than color light source may be employed. The use of at least one of feed forward and feedback control provided by maximizing an output of the photo detector allows an optical pulse having a short width to be realized.

摘要： An optical-fiber light amplifier using rare-earth-doped optical fibers. The light amplifier combines first and second excitation light from first and second sources to form combined excitation light and divides the combined excitation light for inverted distribution to both two optical fibers. The light entered one optical fiber and that entered the other optical fiber are polarized so as to be perpendicular to each other so that fluctuation of output level is prevented without mutual interference. Alternatively the first excitation light and the second excitation light may have different wavelengths; also in this case, fluctuation of level is prevented without any interference.
