Abstract: PURPOSE: To enable to obtain stable color balance under high intensity of illumination, by improvilg the lowering of modulation due to optical unclearness, through the narrow width of the transparent section of stripe shape chrominance filter than that of colored section.  
     CONSTITUTION: Taking the white section of the stripe filter 71 as the light transmitting section (width Δt) and the hatched section as light interrupting section, to Δt and the pitch width T of the filter 71, the color carrier modulation signal obtained at the pick up tube is the pulse train 72(f(t)), amplitude A, pulse width Δt, and period T. Next, the fundamental component C 1  of the signal f(t) and Δt have the relation of sinusoidal waveform taking T as radius. The duty of luminance change on the target surface is effectively changed if T is smaller due to optical unclearness of C 1 . To compensate this, Δt is set smaller than 1/2 of T, but sicne C 1  moves to the point P of Δt=T/2 from the point Q of Δt < T/2 , maximum C 1  is obtained if T is smaller, and the color carrier modulation is optimized.

Filed: 1984-06-07
Abstract: PURPOSE:To prevent an inverter from failing in commutation by providing a stop controller having a memory for controlling an output in a gate controller, and reducing the output current as a DC voltage drops at the stopping time. CONSTITUTION:A pulse width control inverter converts a DC from a DC power source 1 through a breaker 2, a DC filter 3, an inverter 4, an AC filter 5, and an output breaker 6 to an AC, and supplies it to a load 7. This inverter 4 amplifies by an amplifier 12 a deviation between the output voltage and the output of a voltage reference setter 11, and is controlled through a phase shifter 14 and the like. In this case, a memory 61 for holding the output level of the amplifier 12 simultaneously when the breaker 2 is turned OFF is provided between the amplifier 12 and the shifter 14. Thus, when the inverter is stopped, the shifter 14 maintains the output pulse width constant by the output level of the amplifier 12 held at OFF time, thereby obtaining the turning OFF time constantly.
