摘要： PROBLEM TO BE SOLVED: To provide a gas meter employing a multistage sensing type earthquake sensor outputting a different signal corresponding to the intensity of a sensed earthquake and capable of controlling the cutting-off of gas corresponding to the intensity of a detected earthquake. SOLUTION: A gas cut-off controller 7 performs the cut-off control of gas so that a generated earthquake is regarded as a small one to perform the restorable cutting-off of gas, when only a first stage pulse signal is generated within a specific period according to incorporated gas cutting-off logic on the occurrence of an earthquake. The generated earthquake is regarded as a big earthquake when first and second stage pulse signals are generated to perform the non-restorable cutting-off of the gas. The generated earthquake is regarded as a shock when only the second stage pulse signal is generated to perform no cutting-off of the gas. By this constitution, the non-restorable immediate cutting-off of the gas is not performed by an insignificant earthquake and, when a person touches with gas piping or beats a carrying cargo against the gas piping, the immediate cutting-off of the gas by erroneous operation is prevented.

摘要： PROBLEM TO BE SOLVED: To obtain an inexpensive seismometer for estimating the rocking of an earthquake from on/off signals that are obtained by processing seismic waves by accumulating on time every time when an on pulse is inputted from a detection part and estimating the seismic intensity of the earthquake from the seismic intensity and the correlation relationship of the total on time per unit time. SOLUTION: A sensing part A is a steel-ball-type seismometer, a switch part is opened and closed by allowing a steel ball to press a movable piece by the vibration of earthquake, and on/off signals are outputted. The seismometer does not operate due to a slight vibration and no signals due to the vibration of a building other than earthquake are outputted. Then, when the sensing part A detects an earthquake, on/off pulses are outputted. An operation- processing part B consisting of, for example, a microcomputer starts operation when an on pulse is inputted from the sensing part A, accumulates the on time every time when the on pulse is inputted, and estimates the seismic intensity of the earthquake from the correlation relationship between the seismic intensity and the total on time per unit time and outputs concentration from an output part C.

摘要： PROBLEM TO BE SOLVED: To provide a switching mechanism and a trigger switch use of which enables reduction of a load at forced dissociation of deposited contacts. SOLUTION: A movable contact 14 is provided at one end of a movable piece 10, a fulcrum 16 is provided at the other end, and a contacting part 18 which makes contact with a cam part 20 of a plunger part 6a is arranged between the contact 14 and the fulcrum 16. Thus, the interval between the movable contact 14 and the contacting part 18 on which the cam part 20 acts is set to be shorter compared with a conventional mechanism of a double-arm type, consequently the movable contact 14 can be forcibly dissociated by a low load.
