摘要： PROBLEM TO BE SOLVED: To provide an emergency gas shut-off device provided with a sure leakage judgement means that never erroneously displays leakage information even when the gas consumption of a low flow rate is intermittently continued for the long period of time. SOLUTION: A timer stopping means 4 is provided for a leakage timer 5 for counting the duration of a gas flow exceeding a lower limit flow rate value. After a gas flow rate exceeds the lower limit flow rate value and the leakage timer 5 starts time counting, when a gas equipment is operated and the return to be higher than a minimum using range section of the gas flow rate is detected, the leakage timer 5 stops the time counting, the duration is integrated and counted only in the case of exceeding the lower limit flow rate value even when the operation of the gas equipment is stopped and the leakage information is displayed when integrated time reaches the set time of the leakage timer 5 and leakage judgement is surely made possible.

摘要： PURPOSE:To achieve a compact configuration and space saving by inserting lead terminals into the base part of a base member, and connecting a gas detecting element and a explosion-proof net. CONSTITUTION:A lead fram 1 is formed of lead terminals 2-5, a supporting piece 6 having a recess part 6a for determining the position of a gas detecting element and bars 7 and 8 at a constant pitch. The terminals 2-5 are inserted into the base part of a base member, and the gas detecting element and an explosion net are connected. The explosion-proof net is formed in a U-shaped corner pattern covering the opening part of the base member. When the terminals 2-5, the supporting piece 6 and the bars 7 and 8 are blanked, the recess part 6a is formed at the same time. Then, the position accuracy of the recess part 6a and the terminals 2-5 can be readily obtained. Since the base member, the gas detecting element and the explosion-proof net are formed in the U-shaped corner patterns, the compact configuration and the space saving can be achieved.

摘要： PROBLEM TO BE SOLVED: To obtain a gas-meter controller which can investigate a cause for the cutoff of a gas and whose reliability can be enhanced by a method wherein the progress or the like of every generated event is recorded on a memory in a microcomputer. SOLUTION: A microcomputer in a gas-meter controller 3a reads out a signal by using an interface which is used to set a function and to test an operation, the state of the operation is judged, and a cause or the like for the generation of a cutoff event and that for the consumption of a battery can be investigated. In addition, it is possible to know the existence of the generation of an inessential reset operation due to the influence of a noise or the like. When the causes can be analyzed, it is possible to judge whether they are a normal cutoff phenomenon caused by the usage state of a gas. The abnormality of a microcomputer system and that in terms of hardware can be discriminated by confirming the cutoff of the gas irrespective of the nonexistence of cutoff event data. In addition, the consumption of the battery at a time when the turning-on operation of an LED is left and the consumption of the battery caused by the usage environment of a meter at a time when the input signal of a seismographic device is generated frequently can be analyzed.

摘要： PURPOSE:To reduce the electrifying current of a light emitting element by setting to a current value necessary for transmission at the time of transmission of the set conditions and to a low current value enough to visual recognition at the time of displaying the operation signal. CONSTITUTION:A signal output terminal PO1 for output of the input setting conditions together with a signal output terminal PO2 which outputs an operation signal in response to the control signal of a control part 3 is provided. The base of a transistor TR 9 of a series circuit consisting of this TR 9 and a resistance 7 is connected to the terminal PO1. Then a series circuit consisting of a resistance 8 and a TR 10 is connected in parallel to the circuit consisting of the resistance 7 and the TR 9, and the base of the TR 10 is connected to the terminal PO2. That is, the setting conditions are outputted from the terminal PO1 at the time of inputting of the setting conditions, and the current value necessary for transmission and decided by the resistance 7 flows through a light emitting element 6. Meanwhile the corresponding operation signal is outputted from the terminal PO2 when a connection signal is outputted. Then a current enough to visual recognition and set by the resistance 8 flows to the element 6.

摘要： PURPOSE:To shorten a delay time at the time of spraying an inspecting gas and to facilitate inspection, by providing a gas varying speed monitoring circuit which monitors the varying speed of gas density and shortens the delay time of a delay circuit when varying speed is high. CONSTITUTION:A gas detection circuit 1, when detecting the gas leaked in the air, sends its output to a gas density decision circuit 2. The circuit 2 decides the gas density from input, and sends an operating signal to the delay circuit 3 when deciding the excess of the gas density over alarm density. The circuit 3 delays the output of the circuit 2 delaying by a prescribed time so as not to issue an alarm by a noise, etc., to an alarm circuit 4 as an alarm signal. The circuit 4 issues a gas leak alarm by receiving the signal. The gas varying speed monitoring circuit 6 receives the signal from the circuits 1 and 2, and defects the varying speed of the gas density, and shortens the delay time by sending the signal to the circuit 3 when the varying speed of the gas density is high. In such a way, it is possible to shorten an inspection time by shortening the delay time by spraying the inspecting gas.

摘要： PURPOSE:To improve the reliability and reduce the size by using semiconductors instead of conventional mechanical contacts for a receiving means for setting functions to a gas meter 1 mounting a microcomputer 3-1 which detects a gas flow rate by a sensor 12 and closes a cutoff valve 13 through a transistor(TR) 8 if the flow rate is abnormal. CONSTITUTION:Transistors(TR) 5-1, 6-1, and 7-1 are turned on off, and on in the illumination period of the LED 4-1 of the gas meter 1 and then the LED is energized to make a display. In the lighting-off period, the TRs 5-1, 6-1, and 7-1 are turned off, on, and off and the LED 4-1 becomes to be in a zero-bias state, so that the light transmission signal for function setting which is outputted from the LED 4-2 of a setter 2 can be received. With this light signal, a current flows to the gas meter 1 in the path of the feedback resistor 10-1 of an operational amplifier 9-1, the LED 4-1, and the TR 6-1, and the output voltage of the operational amplifier 9-1 at this time is binarized by a comparator 11-1 and read out by the microcomputer 3-1.
