IPC: H04L27/22
Filed: 1993-03-02
Abstract: PURPOSE:To exclude the effect of a frequency error and a phase error by generating a carrier and a frequency conversion signal in a transmitter and a receiver based on a data clock signal so as to eliminate the need of a special carrier reproduction system. CONSTITUTION:A clock signal of a base band signal processing circuit 1 is used for a reference signal and PLLs 4, 5, 6 generate respectively a speed conversion clock signal for a base band signal processing circuit 1, a modulation local signal for a modulator 2, and a local signal for a transmitter 3 to provide them. On the other hand, in the demodulator side, a clock extract section 10 extracts a clock signal synchronously with the signal speed for a radio period from an output of a receiver 7 and PLLs 11, 12, 13 generate a local signal of the receiver 7, a demodulation local signal of a demodulator 8 and a speed conversion clock signal for a base band signal processing circuit 9 respectively based on the clock signal as the reference signal to provide them. thus, the production of a frequency error within a radio section is eliminated and high accuracy is attained and the configuration of the demodulator is simplified.

Title: Manufacture of vapor-deposition galvanized steel sheet
Inventor: FUKUI YASUSHI
IPC: C23C14/16
Filed: 1992-01-31
Abstract: PURPOSE:To activate the surface of a steel by ion beam etching with small quantity of irradiation and to manufacture a vapor-deposition galvanized steel sheet suitable for a high speed line. CONSTITUTION:The surface of a steel is activated by Ar ion beams. At this time, by incorporating easily oxidizable elements such as Si, Cr and Al, the quantity of the irradiation of the Ar ion beams required for forming a vapor- deposition galvanized layer having good adhesion is reduced. Furthermore, the temp. of the steel to be introduced into a Zn vapor-deposition apparatus is regulated to <=100 deg.C to prevent the revaporization of the vapor-deposited Zn. The oxidized film formed on the steel contg. the easily oxidizable elements is dense and thin. Thus, the surface of the steel can be activated by the small quantity of irradiation of the ion beams, and a vapor-deposition galvanized layer excellent in adhesion can be formed. Consequently, the objective vapor- deposition galvanized steel sheet can be manufactured at a high speed without using an ion source with large capacity or the like.

IPC: H01S3/139
Filed: 1999-02-22
Abstract: PROBLEM TO BE SOLVED: To avoid imperfections, which accompany mechanical adjustment of a deviation between wavelengths, and to gurantee the continuity of a change in the wavelengths by a method wherein a continuoutly wavelength-tunable monomode laser source is provided with an additional fine-control means, which is actuated from the approximate continuous tunability position so that the deviation between the wavelength can be prevented from reaching one of the threshold values to cause a mode hopping. SOLUTION: One part 41 of a luminous flux 42 emitted from a laser source 40 is sampled by a separation means 43 and is measured by a photoelectric detector 44 to find the measured value of a deviation (λe-λs) via a first processing unit 45 and an actuator 49 of the source 40 is actuated on the basis of the measured value via a control means 47. A mechanical adjustment of the deviation is not a complete one, the deviation between wavelengths λe and λs is not kept at zero, the value of the deviation is fluctuated, but so long as the fluctuations remain in the range of λs-Δλe/2 or λs+Δλe/2, the continuously wavelength-tunable monomode laser source 40 continues to operate in the same longitudinal mode without causing any mode hopping.
