Filed: 1987-05-09
Abstract: PURPOSE:To reduce the cost and time of wiring construction by setting mutually different sensor for respective sensor devices and allowing a security guard terminal equipment side to decide detection signals while specifying those sensor numbers in order. CONSTITUTION:A security guard terminal equipment, controls a sensor number transmission part 3 by its control part 2 to sends out numbers that the sensor device 13-1-13-n specify as sensor specification numbers in order. The sensor specification numbers are supplied as parallel 4-bit data to sensor number comparison parts 15-1-15-n. Only a comparison part 15-n which matches with a sensor number outputs a coincidence signal. Consequently, the detection signal of the corresponding sensor 17-n is outputted and sent to a sensor output line 10 to reach a sensor signal reception part 4. The control part 2 decides this detection signal to know whether abnormality occurs or not.

Title: Clock stabilizing circuit for video interface
Inventor: YAMAGUCHI KANEO
IPC: G09G1/00
Filed: 1988-05-10
Abstract: PURPOSE:To maintain a sampling clock stable and to improve the picture quality of a color hard copy by providing a means which detects out-of-phase edges in a horizontal synchronizing signal and inhibits the phases of the parts from being compared. CONSTITUTION:The horizontal synchronizing signal is inputted as a reference signal (c) to a phase comparator through a terminal (d) of an FF 1 and an AND gate 4. A comparison signal input (b) to the comparator 7 is obtained by passing a signal (c) which is generated by dividing the frequency of the sampling clock from a PLL circuit 8 through a delay circuit 2 and an AND gate 5. A CPU 6 controls a NAND gate 3. Here, the FF 1 detects whether the horizontal synchronizing signal is at H or L to generate H unless said signal has no leading edge, and a gate 3 is masked with a signal (d) under the command of the CPU 6, thereby inhibiting the comparator 7 from making a phase comparison. The sampling clock is therefore held in a stable state.
