Abstract: A method for manufacturing a terminal that has electrical connection with a component by pinching and holding the component using a pinching part provided in a part of each of two arms. The method includes a first process of forming a first gap G1 between the two pinching parts, and a second process of plastically deforming a part of the arms so as to make the gap between the pinching parts to be a second gap G2 smaller than the first gap G1.

Abstract: A flow rate measuring device simplifies calculation, reduces memory required for calculation, absorbs variations due to manual operation and, depending on the state of ignition, improves the accuracy of appliance identification by extracting features of appliances. The flow rate measuring device includes: a difference value conversion unit that converts into codes difference values of the flow rate measured at constant time intervals by an ultrasonic flowmeter; an appliance feature extraction unit creates an appliance feature code string indicating a feature of each appliance by, for example, making comparison and judgment using a third last code, a second last code, a last code and a current code of the codes obtained at constant time intervals, and by performing code deletion; and an identification unit performs appliance identification by comparing the appliance feature code string with an appliance inherent feature code string indicating the feature code string inherent in each appliance.

Abstract: A newly-purchased gas appliance is detected and reported to a gas administrator. There are provided a flow rate detection portion, a flow rate calculation portion, a code extraction portion, an initial code learning portion, a code maintaining portion, a code judging portion, an additional code learning portion, and an external communication portion. The code extraction portion extracts a code pattern E. The initial code learning portion gathers similar code patterns E as a gas appliance code pattern F. The code judging portion judges whether or not the code pattern E matches any of gas appliance code patterns F held by the code maintaining portion within a predetermined range. The code patterns E that have failed to match are subjected to additional identification of a gas appliance in the additional code learning portion.

Abstract: An object is to prevent a mistaken shutoff caused by the mistaken registration of an appliance of which an amount of gas used changes. An individual flow registration maintenance unit maintains a registered flow rate deleted due to an increase/decrease in flow rate, again, performs determination on the flow rate maintained when a new flow rate is registered or a flow rate added with the maintained flow rate, and in the case where it is regarded to be the same, re-register the maintained flow rate.

Abstract: It is an objective to appropriately assure a function of limiting use of appliances that cause changes in quantities of gas used.

Abstract: A use condition of gas equipment is monitored. An abnormality determination unit 26 determines whether or not a use flow volume obtained by detecting a flow velocity obtained by measuring a signal transfer time in a medium using a flow velocity detection unit 17 and converting the detected flow velocity into a flow volume using a flow volume calculation unit 25. When the shutoff unit 27 shuts off a fluid path 1 when it is determined that there is abnormality, a return signal is output from a return unit 28 to a shutoff unit 27 in order to use the gas again by opening the fluid path. Simultaneously, when a return time-counting unit 29 starts the time-counting operation, and then, a predetermined time period has been elapsed, the flow volume calculation unit 25 determines whether or not a predetermined flow volume of greater flows in order to identify whether or not all of the gas plugs of the gas equipment connected to the downstream of the gas shutoff apparatus 27 are closed.

Abstract: An object of the invention is to avoid a gap between the total using amount of gas and the sum of a plurality of change amounts held in a gas cutoff device. The gas cutoff device includes a flow rate detection unit 11, a flow rate calculation unit 12, an increase and decrease calculation unit 13, an increase and decrease determination unit 14, a valve driving unit 15, a valve 16, an increase and decrease correction unit 17, and a constant increase and decrease correction unit 18. The increase and decrease determination unit 14 acquires a corrected change amount ‘G’ from the increase and decrease unit 17 or the constant increase and decrease correction unit 18 and adopts the amount as a new change amount ‘C’. In this way, it is possible to prevent the using time of gas until the gas path is closed from being lengthened.

Abstract: A non-insulating DC—DC converter is formed of a first semiconductor switching element for reducing a DC voltage from a high-voltage battery, a control circuit connected to the first semiconductor switch element for controlling pulses relative to the first semiconductor switching element, a second semiconductor switching element provided on an output side of the first semiconductor element, a capacitor connected between the first and second semiconductor switching elements in parallel, and a first control circuit connected to one end of the capacitor and an output side of the second semiconductor switching element. The first control circuit detects a voltage at the one end of the capacitor and a voltage on the output side of the second semiconductor switching element, and turns off the second semiconductor switching element if an overvoltage occurs at the one end of the capacitor. The damage of the internal elements due to an overvoltage or a reverse current is prevented.
