摘要： PURPOSE:To reduce the number of blocking times while attaining safety, by changing the time reaching the blocking of gas from a time, when an accident of gas from a time, when an accident was generated, corresponding to a time zone and the flow amount of supplied gas when the blocking of gas is performed on the basis of a gas leakage detection signal. CONSTITUTION:When gas leakage is generated in a gas instrument 3, a gas leakage detector 1 is operated to send out gas leakage information to an operation circuit 23. Because gas flow amount information is always sent to the operation circuit 23 from a flowmeter 5, the time for blocking gas is operated from the gas flow amount information and time information to perform the setting of the time of a timer 24. The timer 24 applies gas blocking information to blocking valve 4 after the set time was elapsed. At this time, because the operation circuit 23 monitors the time information from a clock circuit 25, said circuit 23 performes different operation corresponding to a time zone.

摘要： PURPOSE:To shorten the initial alarm time by constituting a detecting part of a stress sensitive body of a metallic oxide semiconductor, a pair of electrodes for measuring the resistance change of the sensitive body, and a heater for heating the sensitive body on a substrate, and forming a load circuit of at least a positive characteristic thermistor as a load to the sensitive body. CONSTITUTION:This gas leak alarm has a detecting part and a load circuit. In the detecting part 1, a stress sensitive body 6 made of a metallic oxide semiconductor, a pair of electrodes for measuring the resistance change of the sensitive body 6, and a heater 5 for heating the sensitive body 6 are provided on a substrate. Meanwhile, the load circuit is comprised of at least a positive temperature coefficient thermistor 15 as a load to the sensitive body. A response characteristic 23 of the thermistor 15 and the characteristic 22 of the sensitive body assume approximate curves to each a set resistance value RA. The initial alarm time of the sensitive body 6 of this gas leak alarm is shortened to 1/3 displayed by a characteristic 21 of a conventional sensitive body. Since the resistance value of the sensitive body 6 is a small value approximate to the resistance value of the thermistor 15 before it reaches the set resistance value RA, the sensitive body 6 generates heat with consuming a large amount of power and reaches the set resistance value RA quickly.

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.

摘要： PURPOSE:To speedily detect an abnormal flow rate by providing a shift register which stores flow rate pulses of a constant time and an up/down counter which integrates flow rate pulses. CONSTITUTION:The shift register has N-bit constitution and inputs flow rate pulses while shifted successively with a clock signal from a signal source 5. Therefore, flow rate pulses of the constant time T are held in the shift register 4, whose contents are led out in order with the clock signal. Then when pulses are shifted out, the counter 3 counts down. Then, it is decided whether there is a flow rate pulse input or not and when so, '1' is set in the shift register '1' and the counter 3 counts up. The counted value P is compared with a set value M by a comparator 2 to detect an abnormal flow rate state when P>=M.

摘要： PURPOSE:To make it possible to prevent unneeded long-period operation due to initial error information even if the delay time is short, by allowing a circuit not to operate for mixed time at the time of power feeding by using a smoothing capacitor and diodes. CONSTITUTION:When the power supply is put to work, no Zener currents flows from Zener diode ZD1 to diode D2 until the charging voltage of smoothing capacitor C3 reaches the Zener voltage. The time depends upon resistance R1 and the time constant of capacitor C3. If an input signal is gemerated at input-signal secondary winding T2 in this state, the signal current is cut off by diode D2, so that a charging voltage of the polarity applying a reverse bias between the base and emitter of transistor Tr1 will never be developed in capacitor C1. Transistor Tr1, therefore, remains conductive and capacitor C2 is not charged, so that the delay circuit will never operate. When the charging voltage of capacitor C3 reaches the Zener voltage of Zener diode ZD1 afterwards, the delay operation starts.
摘要翻译：目的：即使延迟时间短，也可以通过使用平滑电容器和二极管使供电时的电路不工作在混合时间，从而可以防止由于初始误差信息引起的不必要的长时间操作。构成：当电源工作时，平稳电容器C3的充电电压达到齐纳电压之前，齐纳二极管ZD1不会流过二极管D2。时间取决于电阻R1和电容器C3的时间常数。在这种状态下，如果在输入信号次级绕组T2输入信号，则信号电流被二极管D2截止，从而在晶体管Tr1的基极和发射极之间施加反向偏置的极性的充电电压将永远不会在电容器C1中开发。因此，晶体管Tr1保持导通，电容器C2未充电，因此延迟电路将永远不会工作。当电容器C3的充电电压到达齐纳二极管ZD1的齐纳电压后，延迟操作开始。
