摘要： PURPOSE:To securely prevent oxygen shortage from occuring due to a trouble in a ventilator by a method wherein a sensor is placed in a ventilation air passage and the ventilating function is checked through the change of the resistance of a thermistor. CONSTITUTION:The sensor 8 is placed in the air passage of the ventilator 1 to directly detect the air ventilation. When a trouble occurs in the ventilator 1 and sufficient ventilation is not conducted, the temperature of the sensor 8 such as a self- heating thermistor is raised and the electric resistance thereof is reduced. As a result, a comparator 30 which has been receiving the logical level ''0'' receives newly the logical level ''1'', so that the condition is recognized as abnormal and an alarm is raised by a buzzer 32. Accordingly, oxygen shortage can be securely prevented even at the time of the trouble with the ventilator 1.

摘要： PURPOSE:To obtain a safety system for combustion apparatus, extremely simple in its circuitry, economical and highly reliable in operation, by a method in which an extremely small thermoelectromotive force of thermocouple is detected by a comparator. CONSTITUTION:Since thermocouple 77 produces an electromotive force if burner is ignited normally, voltage at the minus terminal of comparator 9 becomes lower than the voltage at an intermediate point between resistances 13 and 14. On the other hand, peak value of oscillating voltage impressed to the plus terminal of comparator 9 is at most the voltage at said intermediate portion between resistances 13 and 14 if capacitor 56 is discharged completely. Therefore, output of comparator 9 is oscillated and the oscillating voltage is transmitted to the next stage, so that solenoid valve 89 is kept in its open position and combustion is continued. Here, in case that flame of burner happens to be extinguished by wind or overflow of soup or the like during combustion of the burner, thermoelectromotive force is lowered by the extinguishment of flame, so that the voltage at the minus terminal of comparator 53 becomes higher than the upper limit value of oscillating voltage at the plus terminal and the output terminal is kept always at low level. Therefore, oscillation is not transmitted to the next stage, so that solenoid valve 89 is closed.

摘要： PURPOSE:To realize the manipulation and safety of an equipment and also to secure a high fail-safe performance against a fault of parts, by detecting combustion flames blazing and going off in a short time by using a thermocouple which detects combustion frames of a pilot burner, etc. CONSTITUTION:Once a pilot burner is ignited, thermoelectromotive force (e) of thermocouple 9 is generated and a signal amplified by an amplifying circuit is converted by a proportional differentiating circuit into an output of the gradient of the rise of thermoelectromotive force (e). Fluctuations of this output voltage Vs are detected by comparator 31, and consequently transistor 35 is turned ON to turn relay 36 ON. Through another contact of relay 36 not shown in the figure, a solenoid valve, etc., holds gas to the burner to continue the combustion by the burner and also to stop power feed to an igniter. Once the pilot burner goes off, thermoelectromotive force (e) of thermocouple 9 decreases and the signal from the amplifying circuit is converted by the proportional differentiating circuit into the output of the gradient of the fall of thermoelectromotive force (e) and variations of the output voltage Vs are detected comparator 31 to turn transistor 35 OFF, thereby closing a gas circuit.
