Filed: 1984-07-30
Abstract: PURPOSE:To prevent gas leakage from an auxiliary burner even when the pressing force is small and also to prevent discharge of raw gas from a main burner when a water plug is opened, by connecting a resistor in parallel to a normally- closed switch to a discharge circuit, in the titled circuit in which the normally- closed switch connected to the main burner is interposed in the discharge circuit of the condenser. CONSTITUTION:A solenoid 4a of an electromagnetic valve 4 is connected to the discharge circuit 21 through a movable contact 18c and a stationary contact 18b. A resistor 23 is connected to the discharge circuit 21 in parallel to a normally- closed switch 22. As a result, when a water flowing operation is carried out and the switch 22 is opened, the charge of a condenser 17 is discharged through a resistor 23. Accordingly, when a fire-extinguishing push-button 24 is depressed, a thermoelectromotive current of a thermocouple 15 is cancelled, and a safety valve 4 is immediately closed. Hence, even when an ignition push-button 8a is pressed in such a degree as not closing an ignition switch 16a, there occurs no gas leakage from the auxiliary burner 2, and even when the water plug is opened, no raw gas leaks from the main burner 1.

Abstract: PURPOSE:To have high precision yaw attitude control with a small, light, and uncostly device by furnishing an external turbulence presuming part which presumes external turbulence through utilization of a tachometer signal from a wheel, and removing the external turbulence as a factor for error in the yaw attitude with an actuator for other than the wheel. CONSTITUTION:To make attitude control of an earth satellite, pitch and roll attitude controls are performed by controllers 2, 4, momentum wheel 3, and reaction wheel 5 using a pitch and a roll attitude angular signal given by an earth sensor 1. The tachometer output signal indicating the number of revolutions of this reaction wheel 5 is data-converted by a tachometer processing part 6, and the result therefrom is converted by an external turbulence presuming part 7 into an amount of angular motion due to external turbulence. The external turbulence presumed by the presuming part 7 is converted by a yaw attitude error presuming part 8 into yaw attitude error, and according to this error a thrust force generating part 9 consisting of actuator such as a thruster is controlled. Thus the yaw attitude error is corrected.
