Abstract: The appts. comprises a battery power source (1) and a first voltage comparing portion (1) which compares a voltage level of the battery with a motor-driving minimum reference voltage to thereby supply an output of it to a microcomputer (10); a second voltage comparing portion (3) comparing the voltage level of the battery with a minimum reference voltage which drives a gas sensing portion (4), thereby to supply an output of it to the microcomputer; the gas sensing portion sensing whether or not there is any gas leakage and inputs a gas leakage signal to the microcomputer; an intruder sensing portion (5) inputting an intruder sensing signal to the microcomputer; a fire sensing portion (6) inputting a fire sensing signal to the microcomputer; a motor driving portion (7) driving the motor and a buzzer (8) serving as a warning to send out a warning sound in response to a control of the microcomputer when at least one of the above sensing portions senses an abnormal condition.
Patent KR-950003027-B1 (KR)
Title: Apparatus for compensating phase difference
Inventor: KIM DOK-HWAN
IPC: H04N7/085

Granted: 1995-03-29
Abstract: The circuit provides an accurate phase compensation by comparing the phase of the inserted pattern with the signal pattern at encoding phase. The circuit includes: (a) a pattern recognizer(10) which discriminates the inserted pattern at encoding phase; (b) a code converter(20) which converts the signal of the pattern to an unsigned format; (c) a comparing circuit(30) which generates lead or lag pulses by comparing the sizes of adjacent 3 pixels; (d) a clock control circuit(40) which generates clock lead or lag pulse by counting the lead or lag pulse; (e) a clock arbitrator(50) which controls the clock phase using delay elements.
