Title: Video signal processor
Inventor: YAMASHITA HARUO
IPC: H04N5/14
Filed: 1987-12-25
Abstract: PURPOSE:To enlarge the contrast of a recording image while matching with an image by detecting the voltage of the minimum level of an RGB video signal in an effective picture with a minimum level setting means and adding a voltage, which corresponds to the output of this detecting means to the negative reference of an A/D converter. CONSTITUTION:An analog switch 24 is turned on only during the effective picture by a signal (c) to express the effective picture. This electric potential is held by a capacitor 25 and impedance-converted by a transistor 26. Then, a voltage shift part by diodes 20, 21 and 22 is compensated and the potential goes to be a minimum level detecting output (j). When the minimum level detecting output (j) is higher than a prescribed voltage (m), a transistor 30 is cut-off. By resistances 40 and 41, a black level setting means receives the potential, which executes the interior division of a black level limiting means output l and a pedestal potential (h), by a buffer with an operating amplifier 42 and outputs it as a black level setting output. By changing the ratio of the resistances 40 and 41, the degree of the emphasis of the contrast is controlled and an over-contrast can be controlled.

SOLUTION: At the time of partial load running, an entrance temperature into both turbines, i.e., a HP(high pressure) turbine 6 and a LP(low pressure) turbine 10, is reduced to 5% of a rated load. Then, the guiding blade of a compressor 1 is adjusted until a load is below 50%, and the entrance temperature into the HP turbine 6 is kept constant during the adjustment of the guiding blade of the compressor 1. In this case, the entrance temperature into the LP turbine 10 is lowered so as to prevent the exit temperature of the LP turbine 10 from exceeding a designed rated value. After the adjustment of the guiding blade of the compressor 1, the entrance temperature into both turbines 6 and 10 is lowered first in the LP turbine 10, and then in the HP turbine 6 by shifting a phase. Thus, NOx , and CO emission is reduced to a minimum.
