Abstract: PROBLEM TO BE SOLVED: To rotate a rotation driving section properly with relatively small power when rotating a rotor of an AC generator by means of the rotation driving section and a speed increasing section to let the AC generator generate power. SOLUTION: A generating equipment is provided with a three-phase AC generator 11 having a rotor 35 fixed to a rotary shaft 32, with a stator 38 being located around the rotary shaft 32 and a ring-shaped section surrounding an outer end section of the stator 38, and a manual rotation driving mechanism. The manual rotation driving mechanism includes a speed increasing section 13 engated with a gear 33 fixed to the rotary shaft 32 and a manual rotation driving section 12 engated with the speed increasing section 13, and rotates the rotor 35 of the three-phase AC generator 11 by rotating the manual rotation driving section 12 through the speed increasing section 13 and the gear 33 to let the three-phase AC generator 11 generate power. In this case, the diameter of the gear 33 fixed to the rotary shaft 32 should be larger than that of the rotary shaft 32 and smaller than that of the ring-shaped section of the rotor 35.

Abstract: PURPOSE:To eliminate the ghost signal among the high-band signals by separating the luminance signal containing the ghost signal into the low- and high-band signals and then making use of the correlation output between the low-band signal containing the ghost and the low-band signal containing no ghost. CONSTITUTION:Luminance signal YG containing the ghost signal is obtained through video detection circuit 1 and then supplied to LPF2. And then low-band signal YGL is separated, and then high-band signal YGH is separated via signal YG which is delayed for the fixed time. Signal YGL is then supplied to low-band ghost cancel circuit 5 including transversal filter 6 and gain control circuit 7 to decide the output coefficient of filter 6 in order to eliminate the low-band ghost signal. This output is fed negatively back to compound circuit 8 to obtain luminance signal RW free from the ghost signal, i.e., low-band signal YL. Signals YL and YGL are supplied to differentiating circuits 10 and 11 to form correlation output YR. And output YR and signal YGH are supplied to multiplier 13 to perform the ghost eliminating process. Then multiplication output YH and signal YL are compounded through compounder 14 to obtain luminance signal YW containing no ghost signal.
