Title: Video display device
Inventor: NOZAWA SHINJI
IPC: H04N5/05
Filed: 1996-11-28
Abstract: PROBLEM TO BE SOLVED: To improve the follow-up characteristics of a horizontal synchronizing signal frequency and to perform stable display without the change of a horizontal size by selecting selection input signals corresponding to the unlocked state and locked state of a phase locked loop circuit by a follow-up circuit. SOLUTION: At the beginning of the supply of horizontal synchronizing signals H1, a PLL circuit 1 is in the unlocked state where the signals H1 and VF are not synchronized and a synchronization detection circuit 26 supplies the synchronization detection signals SD of an L level to a switching circuit 27. The switching circuit 27 selects the horizontal synchronizing signals H1 corresponding to the supply of the synchronization detection signals SD of the L level, generates follow-up control signals IF in a voltage/current converter 25 after the respective kinds of processings and controls the current controlled oscillator 15 of the PLL circuit 1. Thus, the PLL circuit 1 is turned to the locked state and the signals HI and VF are synchronized.  Then, the phase relation of the horizontal synchronizing signals H1 and oscillation signals VF is inverted, the synchronization detection circuit 26 turns the signals SD to an H level and the switching circuit 27 selects the oscillation signals VF in response to it.

For a p-type thermoelectric semiconductor electrode, the high temperature side is electrified to be negative by seebeck effect, and the low temperature side is electrified to be positive, so the high temperature side is set for a negative pole, while the low temperature side is for a positive pole. The thermoelectromotive force of a temperature difference battery of this constitution is thus formed of the thermoelectromotive force of the p-type thermoelectric semiconductor, and the thermoelectromotive force of the redox pair serially connected with each other.
