Consequently, the abnormality detection signal is not outputted from the operational amplifier 13 while the amplifier 6, its power source, etc. are operated normally. Thus, a light emitting diode 14a of a light emitting part 14 is not lit then to find it from the external that an amplifying device 4 is operated normally.

Title: Controller
Inventor: TOI TAKUMA
IPC: G05B11/36
Filed: 1988-09-03
Abstract: PURPOSE:To prevent the start-up and stoppage of facility from repeating by setting the maximum value of a controlled variable corresponding to a detecting signal at an arbitrary value by adjusting a variable resistor connected between a motor balancing potentiometer B and a control potentiometer A. CONSTITUTION:The variable resistor R is connected in series to a balancing coil on one side, and the stopping position of the contact B1 of the motor balancing potentiometer B is regulated by adjusting the amount of rotation of a control motor CM by the variable resistor R. In other words, the maximum amount of combustion Fmax corresponding to the proportional zone of boiler pressure P can be varied by changing the variable resistor R corresponding to the magnitude of a load in case of representing the boiler pressure P in the resistor R2 of the control potentiometer A and the amount F of combustion in the resistor R4 of the motor balancing potentiometer B. Thus, it is possible to vary the maximum value of the controlled variable (the amount F of combustion, etc.) for a control signal (boiler pressure P, etc.) to an appropriate value. In such a way, the number of times of start-up and stoppage of the facility can be reduced to zero, or reduced remarkably.

Title: Burner element
Inventor: ABE FUMIO
IPC: F23D14/16
Filed: 1985-10-04
Abstract: PURPOSE:To enable a stable combustion to be carried out within a wide range of combustion load by a method wherein a mean fine hole diameter of a part forming a combustion surface of a ceramic porous body is made larger than a mean fine hole diameter of a part facing to a mixture gas inlet. CONSTITUTION:Although mixture gas to be supplied from a mixture gas supplying hole 2 of a burner head 1 passes through fine holes communicating with the front surface and the rear surface of a ceramic porous body, reaches to a combustion surface from a mixture gas inlet port and then is ignited there, the ceramic porous body is made to have a mean fine hole diameter of a part 3a forming the combustion surface larger than a mean fine hole diameter of a part 3b facing to a mixture gas inlet, so that a speed of the passing mixture gas shows a higher value at a part 3b facing to the inlet port and shows a slow speed at a part 3a forming the combustion surface. Even if a back-fire phenomenon occurs at the combustion surface under a combustion of low load, a flow speed of the mixture gas at the part 3b is high, so that the back- fire is not reached to a mixture gas dispersion chamber 4 and so as stable combustion of the fuel can be assured. Since a flow speed of the mixture gas passing through the part 3a becomes relatively low, even if the mixture gas is ignited under a high load, a blowing-off of the flame is hard to occur and thus a stable combustion can be performed.
