IPC: G05F3/30
Filed: 1979-02-23
Abstract: PURPOSE: To obtain stable reference voltage independently of temperature change and power supply variation, by applying the forward voltage of diode D to the base of transistor Tr and inputting the output of Tr to the emitter follower EF circuit.  
     CONSTITUTION: The forward voltage of Q 1  of the constant voltage circuit consisting of diode Q 1  and resistor R 1  is fed to the base and the collector voltage of TrQ 2  providing resistors R 1 , R 2  for the emitter and collector is inputted to FF circuit consisting of TrQ 3  and the emitter resistor R 3 , and the reference voltage Vref is outputted from EF circuit. In this reference voltage generating circuit 1, the temperature  change part of TrQ 3  is cancelled with the inverse temperature change part of the  voltage drop by the resistor R 2  forming the base voltage and the current I 2  of TrQ 2 .  Further, the reference voltage Vref can be compensated even to the variation in the power supply voltage VEE. Thus, the ECL circuit 2 inputting the reference voltage Vref can avoid the malfunction due to lowering in input noise margin to the variation in the temperature change and power supply voltage.

Title: Fuel supply stop device in case of flame blown-out
Inventor: KITA MASAYOSHI
IPC: F23N5/02
Filed: 1982-02-09
Abstract: PURPOSE:To enable to prevent the accident due to the jetting of unburnt gas from occurring by a structure wherein a fuel supply passage is closed by a valve rod actuated with the contraction of a spring occurring automatically when the spring, which expands itself by heat when fuel is burning, cools down with the blown-out of flame. CONSTITUTION:In order to put in use, at first a knob 1 is turned clockwise 90 deg. while being depressed so as to disengage the end part 5 of the spring 4 engaged with triangular projections 7 and 8 therefrom by pushing out the end part 5 with a disc 3 mounted onto a center shaft 2 and to turn 90 deg. in the same direction as that of the knob 1. Owing to the turning of the knob 1, the valve rod 11, which is interlockingly coupled to the center shaft 2 through rods 9 and 10, open a valve in order to supply gas. After that, the spring 4 expands itself anticlockwise due to combustion heat to ride over the projections 7 and 8. If flame flows out and unburnt gas jets under the conditions as just mentioned above, the spring 4 is cooled down by the unburnt gas so that the spring 4 contracts itself and gradually engages with the projections 7 and 8 and consequently pivots the center shaft 2 anticlockwise, resulting in closing the valve with the valve rod 11 in order to stop fuel supply.
