摘要： PROBLEM TO BE SOLVED: To provide a flow rate-measuring device for reducing the power consumption, without reducing flow rate measurement accuracy by reducing wasteful consumption of power. SOLUTION: A passage flow rate measurement means 5a-1 can be operated in either measurement mode, that is selected out of a first measurement mode for measuring passage flow rate, based on physical quantity by measuring the physical quantity that changes according to the flow velocity of gas in a gas channel at every second prescribed time that is shorter than the first prescribed time, and a second measurement mode for measuring the passage flow rate based on the average value of the physical quantity which is measured plural number of times by intermittently measuring the physical quantity at every second prescribed time plural times. A measurement mode selection means 5a-3 selects the first and second measurement modes, when it detects the absence of a pulsating current by a pulsating current detection means 5a-2 and the presence of a pulsating current, respectively, thus enabling passage flow rate measurement means 5a-1 to measure the passage flow rate by the selected measurement mode.

摘要： PROBLEM TO BE SOLVED: To provide a flow rate measuring device for further reducing the power consumption, without bringing about a decrease in a flow rate measuring accuracy. SOLUTION: A flowing speed sensor 1 outputs an analog flowing speed signal, in response to a flowing speed of a fluid in a channel. A drive means 3 continuously drives the sensor 1. An integrating means 7 integrates the analog signal output from the sensor 1 and outputs an analog integrated value signal, in response to the integrated value. Thus, the passing flow rate of the fluid passing the channel is measured, based on the analog integrated value signal from the means 7.

摘要： PROBLEM TO BE SOLVED: To provide an electronic integrating flowmeter eliminating an integration error due to an unevenness and obviating the waste of power consumption, by deciding whether a flow rate calculation is to be conducted or not by considering the output of a flow sensor which is generated, when a flow rate is '0', and omitting the calculation when the rate is '0'. SOLUTION: A flow sensor 10 provided at a fluid supply passage is intermittently driven at every prescribed time to output a signal, in response to a flowing speed of a fluid. An arithmetic means 20-2 calculates a passing flow rate, based on the output of the sensor fetched by a measuring means 20-1, and integrates the calculated passing flow rate to obtain an integrated flow rate. The measuring means decides a prescribed width with a value corresponding to a mean value of the outputs of the sensor, when the passing flow rate is '0' as the center, as an dead zone and hence eliminates calculation of the passing flow rate by the arithmetic means, when the captured output of the sensor falls within the range of the dead zone.

摘要： PROBLEM TO BE SOLVED: To reduce power consumption in a system for automatic metering or the like. SOLUTION: Slave units connected to gas meters or the like and desired to call are grouped into a plurality of groups limit the time within a prescribed time (times t1, t3, etc.), from a call until end of reply thereby ensuring the time for an interruption transmission/reception signal (times t2, t4, etc.). Limiting the number of slave units in an operating state to the number of slave units of a group can suppress power consumption of the slave units.

摘要： PROBLEM TO BE SOLVED: To provide a method for estimating a radio communication available distance by which a radio communication available distance between a transmitter and a receiver can be estimated. SOLUTION: A received power is measured at measuring points 3-1, 3-2, 3-3,..., 3-n, 4-1, 4-2,..., on a concentric circle with a radius of R1 from a transmitter 1, while a received power is measured at measuring points 11-1, 11-2, 11-3,..., 11-n, 12-1, 12-2,..., on a concentric circle with a radius of R2 from the transmitter 1. Then parameters are calculated based on a relation between the received power and the distance, and a variance σ is obtained from the received power values, thus an entire zone deterioration rate is calculated based on the values and a radio communication available distance is estimated by using the entire zone deterioration rate.

摘要： PROBLEM TO BE SOLVED: To provide a method for reclamation and repairing of an existing pipe by which resin-lining ranging over whole length of the pipe and extending to an aiming position can be certainly executed. SOLUTION: As a preparatory process of a first process (a resin transportation process), a resin transportation pig 5, a liquid absorbent 6 and a liquid insulating pig 7 are introduced in a pipe from an opening 31 of a supplying pipe and then required amount of a liquid stream is poured in the pipe to transport the resin transportation pig 5, the liquid absorbent 6 and the liquid insulating pig 7 to a prescribed position in the pipe under pressure. Thereafter, an acoustic wave is emitted from the opening 31 of the supplying pipe to the liquid stream in the pipe and the distance from the opening 31 of the supplying pipe to the liquid insulating pig 7 is measured by receiving a reflected wave from the liquid insulating pig 7. Measured result is compared with an arrival destined distance of the liquid insulating pig 7 in the pipe. When an actual position of the liquid insulating pig 7 is judged to be not reached to the destined position, the amount of the liquid is adjusted so that the liquid insulating pig 7 can reach to the arrival destined position, then the liquid V remaining in the pipe is discharged to the outside of the pipe, total amount of a resin plug and the liquid stream is made to be equal to amount of the liquid V and the process is executed at the first processing time.
