Title: Pll circuit
Inventor: YANAGIUCHI HIROSHI
IPC: H03L7/06
Filed: 1998-07-01
Abstract: PROBLEM TO BE SOLVED: To provide a PLL circuit capable of reducing jitters in the cycle of clock signals, reducing the accumulation of the jitters even at a high multiplication rate and supplying stable clock signals. SOLUTION: Up signals Sup and down signals Sdw from a phase comparator are counted and a main counter 202 increases/decreases a counted value M corresponding to the counted result of an N-ry counter 206 for setting the counted value. A P counter 208 counts the clock signals PLCK outputted from a frequency multiplier, the counted value M of the main counter 202 is selected and outputted to the frequency multiplier by a selection circuit until the counted value reaches the counted value A of the N-ry counter 206 and an arithmetic value (M±1) is selected and outputted to the frequency multiplier while the counted value of the P counter 208 is from (A+1) to (N-1). Thus, the jitters in the oscillation signals PLCK of the frequency multiplier are reduced and the stable clock signals are supplied.

Title: Disaster prevention lighting device
Inventor: SATO KIMIHITO
IPC: H05B37/00
Filed: 1993-07-28
Abstract: PURPOSE:To provide a disaster prevention lighting device capable of turning off the lamp even if a smoke sensor is not connected well. CONSTITUTION:When fire is detected, in the case a smoke sensor 9 does not detect the smoke, the sensor 9 is turned off, no current flows through a resistance R24, and no voltage generates. A transistor Q5 is kept turned off and a phototransistor PT 1 is turned off to operate an inverter circuit 2. The oscillation is generated by the resonance of a capacitor C10 and a transformer Tr3. A pulse is supplied to a discharge electrode 7 to make a xenon lamp 6 flash. By the looseness of the terminal, the sensor 9 is not connected well and the voltage generates in pulse state in the resistance R24. Accordingly, even when the transistor Q5 is turned on, the pulse is taken in the capacitor 12 so that a light emitting diode LED 3 does not turn on. Thus, the inverter circuit 2 does not stop and the xenon lamp 6 can be prevented from being turned off.
