摘要： PROBLEM TO BE SOLVED: To provide a flow rate interrupting device that can detect any abnormality of a microcomputer, and investigate its cause and take a measure even if an initial processing is performed in the microcomputer due to the abnormality of the microcomputer.
SOLUTION: A microcomputer reset pulse oscillation circuit 16 outputs a reset signal accompanied with an abnormal signal outputted from a binarizing circuit 11 in the abnormal condition of a microcomputer 1, and the microcomputer 1 performs initial processing. In case when the microcomputer 1 can read a time-up signal outputted from a watchdog time-up pulse oscillation circuit 17 on the way of the initial processing, it is judged that resetting is done due to the abnormality of microcomputer, and an indication lamp 12 flickers to announce it to the outside.

摘要： PROBLEM TO BE SOLVED: To set the operation function of a gas leak alarm and to receive information which is to be operated in accordance with an instruction from a center by providing a communication means with an automatic metering system and a remote monitoring center system, which is constituted for a different purpose, and a means transmitting various information which the gas leak alarm has to the center. SOLUTION: A CPU 1 detects the drop of the resistance values of a methane gas sensor 2 and a CO gas sensor 3 owing to the occurrence of detection gas through amplifiers 32 and 33 in the respective sensors 2 and 3. The CPU 1 detects the sensor information as the continuous concentration value of gas, compares it with an operation value which is set and judges whether an alarm operation is to be executed or not. Sensor information which the alarm holds is the value of detected gas concentration which is concretely measured. Thus, sensor information is always transmitted to a monitoring center or at prescribed intervals. Consequently, the abnormal change of gas concentration is monitored on a monitoring center-side and abnormality can be detected at timing similar to the alarm.

摘要： PROBLEM TO BE SOLVED: To reduce the consumption of a battery without lowering a role to warn of an abnormal state generation. SOLUTION: The device has plural alarm issuing modes and, when an abnormality is detected by a sensor, an alarm issuing mode consisting of strong alarm contents is selected if the degree of abnormality detected is higher, stronger alarm is issued and, as time goes by since the alarm issuing switched to an alarm issuing mode consisting of weaker alarm contents. Also, the device has an alarm issuing mode for issuing a sound alarm by words and an alarm issuing mode for issuing a pseudo sound alarm consisting of an intermittent sound. A ratio of the sound alarm is made large immediately after the abnormality detection and the ratio of the pseudo sound alarm is made large as time goes by.

摘要： PROBLEM TO BE SOLVED: To make a gas detecting alarm settable in an environment where ambient temperature is changed and make maintainable stable operation even when the voltage of a battery drops after setting. SOLUTION: A temperature sensor 4 is stacked integrally with a gas sensor 2 to measure the temperature around the gas sensor 2 from the output of the temperature sensor 4 at a resting time when a voltage pulse is not applied to a resistance wire 3 for a heater and measure the voltage of a battery applied to the heater 3. Then, a preset pulse applying time is corrected to an optimum pulse applying time for heating the gas sensor 2 to a preset operating temperature in accordance with the applied voltage of the pulse and the ambient temperature measured just therefore.

摘要： PURPOSE:To operate the gas shut-out section safely and simply, monitor the display section, and alarm an abnormal state by sound by providing a control section by which the structure section to operate the return button of the gas shut-out section is remote-controlled, a light-electricity conversion section, and a remote display section. CONSTITUTION:A gas shut-out section is installed at the upper section of a gas meter 16 and formed by a gas shut-out section 1 and a display section 2. A structure section 17 is arranged which returns the closed valve body by pressing down a return button 11 when the gas passage is shut-out by the gas shut-out section 1, and to the structure section 17 a control section 18 which is installed at a remote place through a cable is connected. The display section 2 is provided with a light-electricity conversion section 19 which is opposite to the remote display section 2, and the light-electricity conversion section 19 is connected to a remote display section 20 by a cable. The remote display section 20 is one body with the control section 18. Further, the remote display section 20 incorporates a sound alarm section 21 which sounds in case of abnormality. And, the control section 18 incorporates a shut-out signal circuit 22 which shuts out the gas shut-out section 1. Further, the remote display section 20 is provided with an output circuit 23 which transmits the state of operation in the display section 20 further to a remote place.
