Patent JP-S63160263-A (JP)
Title: Protective circuit
Inventor: SEKI KUNIO
IPC: H03F1/42
Filed: 1986-12-24
Abstract: PURPOSE:To prevent any overcurrent from running in while reducing the IC breakdown by a method wherein a current limiting means substantially cutting off a power supply or limiting current is provided between the power supply and an inner circuit in IC in case the power supply is subjected to any polarity inversion. CONSTITUTION:A current limiting means is composed of a transistor T connected to a base and an emitter E as well as a P type resistance layer formed in an N type island region on a P type substrate. When power supply VCC is in normal polarity, TQ1 actuates the emitter E and a collector C in the reverse direction while a constant voltage circuit 1 is supplied with power supply current to supply TQ2 with bias voltage by a Zener diode ZD for supplying the reference voltage Vref divided by R2, R3. Furthermore, when the power supply VCC is erroneously connected, the TQ1 reaches non conductive state due to zero bias between the base B and emitter E of TQ1 so that the constant voltage circuit 1 may be supplied with no overcurrent to protect IC without fail.

Title: Automatic synchronization device
Inventor: MIYAMOTO HIROKI
IPC: H04N5/44
Filed: 1991-10-25
Abstract: PURPOSE:To eliminate change in an output voltage of an automatic synchronization device (AFT) by means of the luminance of a video image by retaining the output voltage of an FM detection means by means of a retention means during any period other than that of a synchronization signal. CONSTITUTION:A comparator 13 separating a horizontal synchronization signal from a video signal is provided to control the output voltage of an FM detection circuit 5 only during the period of synchronization signal and to retain the output voltage of the FM detection circuit 5 during any period other than that of the synchronization signal. In such a case, a switch control circuit C26 connected to the output of the comparator 13 changes over a switch 27 to the position of a side (a) when the output of the comparator 13 is low, that is, during the period of H. synchronization, and changes it over to the position or a side (b) when the output or the comparator me is high. Therefore, the FM detection circuit 5 which is the output of the AFT performs output only during the period of H. synchronization. Thus,(b) retaining the output voltage of the FM detection circuit 5 during any period other than the synchronization signal, the output voltage of the AFT can be outputted only during a horizontal synchronization signal period without requiring a gating circuit outside a video intermediate frequency IC.
