Title: Service interruption detector of power converter
Inventor: UJIIE AKIHIKO
IPC: H02M7/48
Filed: 1989-04-12
Abstract: PURPOSE:To detect the service interruption of an AC power supply surely by combining a zero-cross comparator, an arbitrary frequency oscillator and an oscillator transmitting a frequency differing somewhat from the frequency of said frequency oscillator. CONSTITUTION:A pulse signal from (60+alpha).NHz oscillator 22 is given to the clock input of a counter (CT)17 and a pulse signal from 60.NHz oscillator 23 is given to the clock input of CT19 to perform counting. The signal of a zero-cross comparator ZC16 obtained from a power supply ES clears the CT17, 19 for every zero-cross. When the power supply ES is normal, a difference alphain the number of oscillations is ignored and judged to be in-phase and a multi-vibrator (MB)21 outputs L signal. When the power supply ES stops, a signal from the ZC16 is not inputted to the CT17, 19, which continue counting. Said difference alpha in the number of oscillations increases every cycle, and the MB21 detects a service interruption and brings the output to H.

Title: Burst-sampling-pulse generator
Inventor: SASAKI MIKIO
IPC: H04N9/44
Filed: 1979-07-17
Abstract: PURPOSE:To adapt a generator to IC-implementation by generating burst sampling pulses only by a digital circuit. CONSTITUTION:Once a horizontal synchronizing signal is input to input terminal 6, the signal is input to reset terminals of FFs 1-4 constituting a 4-bit counter and they are reset to hold output terminal Q4 at a low level. On the other hand, FF7, once applied with the signal at reset terminal P, is preset and output terminal Q5 of FF7 is held at a high level. This state continues until a horizontal synchronizing signal of the low level arrives. When the horizontal synchronizing signal disappears, FFs 1-4 start to count chrominance sub-carrier signal pulses and on arrival of the 8th pulse, output terminal Q4 of FF4 is held at the high level. Then, FF7 outputs the state of a signal arriving at terminal D at the rise of the pulse to output terminal Q5. Burst sampling pulses can be obtained by applying AND circuit 10 with the signal from terminal Q5 and a signal obtained by inverting the horizontal synchronizing signal.
