Title: Short optical pulse transmitter
Inventor: KAWANISHI SATOKI
IPC: H04B10/40
Filed: 1996-09-12
Abstract: PROBLEM TO BE SOLVED: To attain optical transmitter with a short pulse at a high bit rate by eliminating the effect of deterioration in waveform due to higher harmonic wavelength dispersion of a transmission optical fiber. SOLUTION: An optical pulse generated by a pulse light source 301 is coded by a signal generator 303 and an optical modulator 302, and sent to a transmission line as an optical signal pulse. In order to eliminate the effect of higher harmonic wavelength dispersion (dispersion slope) of transmission optical fibers 307-1-307-N, a compensation circuit (waveguide type dispersion slope compensation circuits 305-1-305-N) having a dispersion slope inverse to the dispersion slope are inserted to the transmission line. Thus, in the case of sending a high speed optical pulse (short optical pulse), deterioration in the pulse waveform due to effect of the higher harmonic wavelength dispersion is eliminated to realize the high speed optical pulse transmission.

Abstract: PURPOSE:To maintain the specified rotating quantity integrated with time even if unnevenness arises in a rotating speed so that an exact time display is permitted by setting the rotatable range of a piezo-electric motor by a stopping means and running the motor alternately forward and backward at a specified period. CONSTITUTION:A piezo-electric element 3 excitation signal inputted to an excitation signal input terminal 4 is frequency-divided by FFs 6, 7. The output of the FF6 is inputted to an EXOR gate 10. Since the 1Hz signal for controlling the revolution of the piezo-electric motor inputted to a driving signal terminal 5 is inputted via an FF8 to the gate 10, the Q output of the FF6 inverts at every other second. Then, the outputs of NAND gates 11, 12 are inverted in phase relation alternately 90 deg. at every one second. These signals are impressed via inverters 13, 14 to the electrode of the element 3, then a rotor 1 revolves and repeats the forward and backward revolutions at every one second. The rotor 1 is so constituted that a pin contacts a stopper plate and the rotor is forcibly stopped when the rotor revolves clockwise or counterclockwise.

Abstract: PURPOSE:To improve welding efficiency and welding quality by filling a flux or the like prepd. by incorporating iron oxide, C and the iron powder of the shape defined by the prescribed equation respectively in specific weight ranges therein into a metallic sheath. CONSTITUTION:The component compsn. of the flux is constituted of <=2.0wt% iron oxide, <=0.05% C and <=10% iron powder and such flux is filled in the metallic sheath by which the composite wire is formed.
