Title: Post-purge controller for burner
Inventor: SUZUKI TOMIJI
IPC: F23N5/20
Filed: 1987-12-23
Abstract: PURPOSE:To give no feeling of cold air in post purge, and also to prevent a burner body from being superheated, by constituting the title controller whose judgement means is provided with a combustion control part, a fan motor control part, a combustion detection part, a combustion timer, an arithmetic part and a delay timer. CONSTITUTION:A burning state is converted into an electric signal by a combustion sensor 30 which sends it to a combustion detection part 31. According to the electric signal sent from the sensor 30, the detection part 31 produces an output to a combustion timer 32 only when combustion is judged, thus allowing the timer 32 to count the combustion time. An arithmetic part 33 calculates the value counted by the timer 32 and allows a delay timer 34 to count the post purge time corresponding to the combustion time. Then, when an operation switch 23 is turned off, a combustion control part 25 stops the operation of an electromagnetic valve 27. When the switch 23 is turned off, the timer 34 outputs an operation signal to a fan motor control part 29 during the period of the post purge time calculated while the switch 23 has been kept on, thereby rotating a blowing fan 17 for a predetermined period of time corresponding to the combustion time though the switch 23 is turned off.

Filed: 1989-12-15
Abstract: PURPOSE:To switch a clock signal while preventing glitch by providing plural clock signal input sections, an FF receiving a selection signal, a 3-input NAND receiving an FF output, the selection signal and a clock signal and a NAND receiving an output of the 3-input NAND. CONSTITUTION:Signals from clock signal input terminals 8, 9 and a clock of FFs 1, 2 are inputted to 3-input NANDs 3, 4. The clock signal 8 or 9 is selected by using a selection signal 7. For example, to select the signal 8 from the signal 9, the level is set to H from L in a timing. The selection signal 7 is synchronously with the clock signal selected at present as the system clock. The output from the NAND 4 of the signal 9 is inhibited by the selection signal 7 but since the signal 8 is asynchronous, while the FF1 latches one clock, glitch is prevented and the NAND 4 is opened from the succeeding clock to obtain a prescribed timing and even when the selection signal is asynchronous with the clock, the old and new clocks are selected without any glitch. The switching from the signal 8 to 9 is implemented similarly.
