摘要： A process for producing acidic boratozirconium chloride sols which comprises: reacting a zirconium compound with a boron compound in molar ratios of B/Zr of 0.3-1.2 together with a compound of a metal M other than boron, the metal M being selected from the group consisting of divalent, trivalent, tetravalent and pentavalent metals in molar ratios of M/Zr of about 0.01-1 in water in the presence of chloride ions in molar ratios of Cl/Zr of not less than about 1.The acidic boratozirconium chloride sol may be converted to basic boratozirconium sols by reacting the acidic sol with a basic carbonate compound such as ammonium carbonate.The sols, either acidic or basic, are readily gelled by contact with a dehydration solvent such as methanol or acetone.The gel is calcined at relatively low temperatures to provide zirconia which is either very pure or stabilized in varied degrees.

摘要： A variable dispersion compensating unit compensates an optical signal, and changes the compensation amount according to a control signal that has a given frequency. After demodulation of the compensated optical signal, error conditions of the signal are monitored and an error signal is output. A band pass filter filters the error signal for a component having a frequency equal to or less than the given frequency. Based on the component and on the control signal, a synchronous detecting circuit generates a compensation amount modification signal. The compensation amount modification signal is superposed on the control signal.

摘要： A method and system for communicating a clock signal over an optical link includes receiving a multimodulated optical information signal including non-intensity modulation for a data signal and intensity modulation for a clock signal. The clock signal is recovered based on the intensity modulation of the multimodulated optical information signal. The non-intensity modulation for the data signal is converted to intensity modulation for the data signal. The data signal is recovered from the intensity modulation for the data signal using the clock signal.

摘要： A tunable filter module which can automatically make the center wavelength in the passband coincident with the center wavelength of a signal light beam according to variations in wavelength of the signal light beam. The tunable filter module includes a beam splitting mechanism for splitting an incident signal light beam into a first beam undeviated, a second beam deflected to one side of the first beam; and a third beam deflected to another side of the first beam, and a multilayer film filter located so as to transmit the first, second, and third beams. A first photodetector is located so as to detect the second beam, and a second photodetector is located so as to detect the third beam. A comparator is connected to the first and second photodetectors to compare outputs from the first and second photodetectors and output a differential signal indicative of the difference between these outputs. A tilt angle of the multilayer film filter is changed according to the differential signal so that the center wavelength in the passband of the multilayer film filter comes into coincidence with the center wavelength of the signal light beam.
