摘要： PROBLEM TO BE SOLVED: To enable a solenoid valve to be reset automatically to the original condition when it is operated with a shock by a person by detecting induction voltage generating in a coil when it is operated with a shock by a person, and resetting the valve to the original condition. SOLUTION: Opening/closing control means 2 outputs opening signals SO1 , SO2 and closing signals SC1 , SC2 to valve drive means 3 coomposed of a transistor bridge circuit, and the means 3 applies a current of different voltage porality to a coil 4 of solenoid valve according to these signals. Induction voltage detection means 5 detects the induction voltage generating in the coil 4 when the valve is operated according to a shock by a person, other than according to control signals to outputs a shock close signal PV. When the signal PV is input to the opening/closing control means 2, the means 2 determines no output of close signals SC1 , SC2 thereof to output opening signals SO1 , SO2 , thereby opening the valve.

摘要： PROBLEM TO BE SOLVED: To provide a gas cutoff device provided with the function to detect a closed state and raise an alarm informing when a cut-off valve cuts off a gass passage due to the shock. SOLUTION: When a cutoff valve closes a plug and moves, a valve drive section 4 outputs a cutoff valve release signal B. When the cut-off valve release signal B is outputted due to the shock, since a cut-off request signal A is not outputted from a valve drive request section 3, a shock signal input section 5 judges to have been the shock and outputs a shock detect signal C. Since a shock judgment delay section 6 outputs the shock judgment request signal E after a prescribed delay time lapsed, an open and close valve judgment section 7 confirms the opened and closed state of the cut-off valve and when the closed state is detected, it outputs an alarm informing signal D and an alarm information is raised from an alarm informing section 8. Since the open and closed valve is judged after the vibration is settled by setting up the said delay time, no misjudgment is made.

摘要： PROBLEM TO BE SOLVED: To provide a gas shutoff device capable of detecting a gas leakage whose flow rate is identical to the flow rate of a pilot light even when a registered flow rate of a pilot light is changed by the replacement of a gas apparatus or the like. SOLUTION: A pilot light flow rate determinant section 3 compares a measured gas flow rate value A with a pilot light flow rate holding value which is a registered pilot light flow rate value and outputs a non-identical signal D when they are not the same and an identical signal E when they are the same. When the input of the non-identical signal D is continued for a specified time, an alarm annunciation section executes alarm information. When a specified time has elapsed from the input of the same signal E, a pilot light flow rate erasure determinant section 6 outputs a pilot light flow rate registered deletion signal F to a pilot light flow rate holding section 4, thereby eliminating the pilot light flow rate holding value C.

摘要： PROBLEM TO BE SOLVED: To eliminate the effect of a transient noise or the like and prevent the occurrence of erroneous judgement by applying the constitution that an input port judgement part inspects voltage, upon receipt of a port judgement normal signal, the abnormality of a circuit is judged when the voltage is equal to or below the preset level and, then, the circuit abnormality is reported. SOLUTION: An input port judgement part 5, upon receipt of an output signal from a periodic timer part 1 to periodically output a voltage inspection signal A, judges the status of an input port and outputs a port judgement normal signal D and a port judgement abnormality signal E. A voltage detection part 2, upon receipt of the port judgement normal signal D, inspects voltage. Then, the voltage detection part 2 outputs a voltage drop signal B, when the voltage is equal to or lower than the preset value, and a voltage normal signal C when the voltage is abnormal. Also, a circuit abnormality judgement part 6, upon receipt of the port judgement abnormality signal E, identifies a circuit abnormality and outputs a circuit abnormality reporting signal F. In this way, the input port judgement part 5 judges the status of the input port to read a judgement signal for voltage inspection, before implementing the inspection, thereby avoiding judgement about a voltage drop in the case of an abnormality.

摘要： PROBLEM TO BE SOLVED: To correctly detect the shut-off of the impact by discriminating the signal to be generated when a shut-off valve is closed by the impact from the noise signal. SOLUTION: When the signal to be generated by the closing and movement of a movable rod in an excitation coil 31 of a shut-off valve 10 by the impact is detected by an impact shut-off detection part 6, and the detected value is inputted in an opening/closing control part 4 as the impact shut-off detection signal, the opening/closing control part 4 makes a judgment to discriminate the impact shut-off detection signal from the noise signal based on the voltage and the pulse width of the inputted signal, and the malfunction by the noise is eliminated. When the impact shut-off is judged, the impact shut-off condition is determined by detecting the closing condition by a valve opening/closing judging part 5, and the impact shut-off is alarmed and indicated to a valve opening/closing indication part 8.

摘要： PROBLEM TO BE SOLVED: To provide a gas shut off device preventing confusion due to the complication of information by limiting information quantity to give a centralized monitoring device at the time of an earthquake. SOLUTION: When a seismoscope 10 detects vibration, an earthquake judging part 3 judges the vibration to be an earthquake not less than a prescribed seismic intensity from its vibration pattern, etc., and outputs an earthquake defining signal. A shut off driving part 4 operates a shut off valve 9 by the input of the earthquake defining signal, and a communication control part 6 fetches only previously restricted earthquake time alarming information from an earthquake time alarming information storing part 7 and an external communication part 11 transmits it to the centralized communication part 11. When a recovering time measuring part 5 measures a prescribed recovering time, the fetching of alarming information by the part 6 is switched to normal time alarming information from a normal time alarming information storing part 8.

摘要： PROBLEM TO BE SOLVED: To provide a gas shutoff apparatus by which the measuring interval of a pressure measurement can be changed and by which a pressure drop according to a situation is detected. SOLUTION: By a measuring-interval signal D which is held by a measuring- interval holding part 6, a pressure-measuring instruction part 5 outputs a pressure measuring signal A to a pressure measuring part 2. A gas pressure B, in a gas passage, measured by the pressure measuring part 2 is input to a pressure-drop judgment part 3. When the gas pressure B is at a prescribed value or lower, a measuring-interval change signal C is output, and a measuring interval which is held by the measuring-interval holding part 6 is changed. When a state that the gas pressure is at the prescribed value or lower continues the prescribed number of times or higher, the pressure-drop judgment part 3 outputs a pressure increase signal E to a shutoff-valve drive part 4, and the gas passage is closed by a shutoff valve 7.

摘要： PROBLEM TO BE SOLVED: To accurately integrate measured values of minute flow rate and to stably display numerical values of the minute flow rate displayed on a display device. SOLUTION: A calculation part 50 of a gas meter includes a forward and reverse determination circuit 60, a flow rate calculation circuit 70, a memory part 80 and a display drive control circuit 90. The memory part 80 includes a cumulative flow rate counter 120 for storing the gas flow rate, and an auxiliary cumulative flow rate counter 130. The flow rate calculation circuit 70 adds a measured instantaneous flow rate q to the minute flow rate cumulative value stored in the auxiliary cumulative flow rate counter 130, and if this added minute flow rate cumulative value reaches a set value (the upper limit value β) or higher, the value (cumulative flow rate), which is obtained by subtracting the upper limit value β from the minute flow rate cumulative value, is added to the cumulative flow rate value of the cumulative flow rate counter 120, and in this case the minute flow rate cumulative value renewed and stored in the auxiliary cumulative counter 130 is β.
