摘要： PURPOSE:To secure synthetic safety of gas supplying by a method wherein a shut-off valve is closed automatically by transmitting the flowing of electric current to a valve driving unit through a resistance when the power source voltage of a micro-computer decreases abnormally, or when an abnormal consumed electric current flows to the micro-computer. CONSTITUTION:In case the micro-computer 5 is under a normal condition, the current flowing into the point (a) of a back-up resistance 8 is small and the voltage of the back-up resistance 8 hardly drops, and the voltage thereof is almost same as the voltage of a capacitor 6. However, the micro-computer becomes abnormal due to noise and aging stress or the like for example and the electric current thereof increases; as a result, the voltage drop of the back-up resistance 8 becomes large and the potential at the point (a) decreases. Then, the base potential of a transistor 12 drops through a resistance 14 to put ON the transistor 12 and the shut-off valve may be operated.

摘要： PURPOSE:To monitor a gas appliance whether combustion is performed or raw gas is leaking without burning, by detecting the flow rate of gas and by observing the changing pattern with time in flow rate. CONSTITUTION:The primary calculator 6 calculates the flow rate, and a result is stored in a memory 7 each time after calculation, while a counter 9 adds 1 to the content stored in it. In such a manner, calculation is continued. When the primary calculator finished calculation on the predetermined number of time, that is the Nth time, the data from the first flow rate F1 to the flow rate FN on the Nth time has been stored in the memory 7. As the content in the counter 9 gets to N, it outputs a signal to start calculation. Receiving the signal, the secondary calculator 10 calculates the rate of change DELTAF=(F-FN)/F1, and the result is outputted. A comparator 12 compares the rate of change DELTAF with a reference value DELTAFa from a reference value generator 11, and when a result is DELTAF

摘要： PURPOSE:To reduce fluctuation of operating voltage by performing thermal treatment after non-electrolytic nickel galvanization as surface treatment of components in magnetic circuit of gas block valve to expose magnetic nickel thus reducing magnetic resistance. CONSTITUTION:Magnetic circuits 17, 18 for operating a valve rubber 14 is comprised of yoke 1, plunger 11 and spring 16 where non-electrolytic nickel galvanization is applied on the surface of material of yoke 1 and plunger 11 or iron then thermally treated. Consequently, iron applied with surface treatment will be magnetic material to prevent function of galvanized film as a magnetic gap thus to prevent deterioration of adsorbing force between plunger and piece resulting in elimination of fluctuation/variation of operating voltage of gas block valve, strict management of the thickness of galvanization film, facilitation of working of parts and cost reduction.

摘要： PURPOSE:To obtain a constant zero judging flow rate regardless of the size number of a meter, by changing the zero judging time in correspondence with the size number of the gas meter. CONSTITUTION:A flow rate sensor 2 transmits flow rate pulses corresponding to the measurement of a gas meter. A size-number selecting switch 3 generates a size number signal corresponding to the size number of the gas meter. An operating device 8 computes the flow rate from the flow rate pulses of the sensor 2 and the size number signal of the switch 3, and has a zero judging part 9, which judges the zero flow rate based on the time interval of the flow rate pulses. The judging point 9 is constituted by the following parts: a time setting device 10, which receives the size number signal and outputs a zero judging signal; a timer 5, which measures the time interval of the flow rate pulses; and a comparator 11, which compares the time interval of the flow rate pulses with the zero judging time and outputs a zero flow rate signal when the interval is longer. Therefore, the zero judging flow rate can be made constant regardless of the size number of the meter used.

摘要： PURPOSE:To measure the flow rate quickly and accurately even after it changes by a method wherein pulses from a flow rate sensor are counted to measure and memorize the time interval thereof and when the current and previous time intervals satisfy a specified relationship, the measurement is stopped to start a new measurement. CONSTITUTION:A flow rate sensor 2 is provided in a gas supply line 1 and is made up of a membrane type gas meter 3 and a lead switch 4 as magnetic field sensor to transmit a flow rate pulse F each time a specified unit weighing volume is measured. The pulse F is inputted into an arithmetic processor 5 which computes the flow rate per unit time. The device 5 is equipped with a counter 6 for counting the pulse F, a timer for measuring the time interval of the pulse F, a memory 9 for memorizing the time interval of the pulse F measured one time ago and an arithmetic processing section 8. The processing section 8 computes the flow rate per unit time while stopping the measurement to start a new measurement when the time intervals measured currently and previously satisfy the specified relationship. Thus, the flow rate can be measured quickly and accurately even after it is changed.

摘要： PURPOSE:To measure a flow rate per unit time accurately by measuring time intervals of flow rate pulses several times, calculating the mean time interval, and calculating the flow rate per unit time form the mean time interval. CONSTITUTION:The reed switch 2 of a flow rate sensor turns off every time a gas meter 1 measures unit measurement volume, and its state change is sent as flow rate pulses to an arithmetic device 3. The arithmetic device 3 measures the time intervals of flow rate pulses sent from the reed switch 2 through a timer 4, and sends the time intervals to a processor 5. The processor 5 calculates the mean value T of the last time interval stored in a storage device 6 and the current time interval sent from the timer 4, form an equation I. Then, the flow rate Q per unit time is calculated from q/T, where (q) is the unit measurement volume. Thus, the flow rate per unit time is measured accurately.

摘要： PURPOSE:To ensure shutting-off of gas in abnormalities by bonding radially a valve rubber to a valve stem provided with a flat top to provide a structure determining the axial position of the valve rubber by an abutting portion having smaller diameter than said top. CONSTITUTION:A valve rubber 15 formed with a valve seat surface 12 abutting against a holding shoulder 8, a central aperture 13 adhering radially closely to a seal groove and a projection 14 on the rear side of the seat surface 12 is fitted onto a valve stem 11 provided with a flat top. Thus, the valve can be easily swung to absorb the inclination of mounting surfaces and a valve seat surface so that gas enclosing property is improved and gas can be positively shut off in abnormalities.

摘要： PURPOSE:To diminish the number of parts of a gas cock unit and prevent it from generating defects, by enabling a solenoid valve pushing cam to use also for the absorption of the excessive push stroke of a solenoid valve after its total push stroke. CONSTITUTION:When a shaft 5 for turning a closer 3 is push-rotated in the opening operation of a gas cock, the closer is first opened to connect a gas passage 6a and a main gas passage 11 to each other. At that time, the claw 35 of a cam 8 for the cock and a cam 29 for a solenoid valve 13 are engaged with each other to turn the cam 29 to push a pin 30 by the cam action part 27 of a cam 23. As a result, the spindle 15 of the solenoid valve is thrusted by a solenoid valve pushing bar 31 to push an attracted plate 15 on an electromagnet 14. When the electromagnet 14 is energized by an electric current from a thermocouple or the like, the solenoid valve 13 is kept open to start combustion on a main burner or the like.
