Title: High voltage generating circuit
Inventor: SAKURAI SOICHI
IPC: H04N3/18
Filed: 1986-11-14
Abstract: PURPOSE:To offer a high voltage generating circuit not causing black stripes on a screen by setting the phase of a high voltage pulse within the blanking period of deflection and setting the phase of harmonic noise caused by the high voltage generating circuit within a horizontal blanking period. CONSTITUTION:The tilted circuit brings the output voltage of an integration circuit converting a horizontal deflection pulse voltage into a saw-tooth wave voltage waveform and a phase delay circuit comprised of a pulse generating circuit using a saw-tooth wave voltage as an input signal into a synchronizing signal or a drive oscillation pulse of the high voltage pulse generating circuit. That is, an integration resistor 7 and an integration capacitor 8 integrate a horizontal deflection pulse (a) to form a saw-tooth voltage (b). Moreover, a capacitor 9, resistors 10, 12 and a level shift diode 11 increase the DC level of the saw-tooth voltage to be a waveform (c). The saw-tooth voltage (c) is fed to the base of a pulse generating transistor (TR) 14, from the collector of which a pulse voltage (d) is generated. The pulse voltage is used as the oscillation pulse of the high voltage generating circuit, fed to the base of the drive TR 16 to drive a high voltage output TR 19, from which a high voltage collector pulse (e) is obtained.

Abstract: PROBLEM TO BE SOLVED: To provide a method and a device for generating a light pulse not reducing a mean light output by half when a frequency is reduced, and an optical signal of a prescribed frequency is generated, having simple constitution and excellent S/N(signal/noise) ratio. SOLUTION: An optical switch 11 of a light pulse generating device 10 is inputted with input light 121 of an RZ(return to zero) light pulse of the frequency (f) from a light pulse generator 12, and converts it into the output light 122, 123 of the RZ light pulse of the frequency f/2 in response to an electric bias signal of the frequency f/2 of a signal generator 13 to output alternately them to two outputs port 14. An optical fiber 15 from one side arm of the two outputs port 14 is coupled with the optical fiber of a port of a light phase adjuster 17 through an optical coupler part 151 in a relation that optical axes are parallel to each other, and doesn't polarize the input light 122.  The optical fiber 16 from the other arm of the two outputs port 14 is coupled with the port 183 of an optical multiplexer 18 through the optical coupler part 161 in the state that tire optical axes are orthogonally intersected with each other, and polarizes the output light 123 at right angle. The optical multiplexer 18 is inputted with the output light 122 and the output light 123 of a polarization plane orthogonally intersecting with its polarization plane. Thus, pulse interference between both is eliminated, and a multiplexed wave 181 of double light intensity and frequency f/2 is outputted.
