  • Publication number: 20190120958
    Abstract: A transducer is provided, which includes an oscillator and a broadbanded matching circuit. In the oscillator, a peak frequency corresponding to a peak transmission sensitivity may separate from a center frequency in a given bandwidth, and a transmission sensitivity may increase as a frequency separates from the peak frequency with respect to the center frequency. The broadbanded matching circuit may be configured to perform an impedance matching so that the transmission sensitivity of the oscillator at the peak frequency becomes substantially equal to the transmission sensitivity of the oscillator at the center frequency.

  • Publication number: 20190019093
    Abstract: An acquisition portion obtains the daily gas consumption amount of a tank from a gas meter. A consumption amount predicting portion predicts future daily gas consumption amounts for the set number of days using the latest gas consumption amount having the same day of the week among the gas consumption amounts obtained by the acquisition portion. A replacement day predicting portion, as a remaining amount predicting portion, predicts the remaining gas amount in the tank using the gas consumption amounts obtained by the acquisition portion and the future gas consumption amounts for the set number of days predicted by the consumption amount predicting portion.

  • Publication number: 20190019136
    Abstract: An acquisition portion obtains daily gas consumption amounts of tanks from gas meters. A consumption amount predicting portion predicts future daily gas consumption amounts for a first set number of days using latest gas consumption amounts having the same days of the week among the gas consumption amounts obtained by the acquisition portion. A replacement day predicting portion predicts the day on which the remaining gas amount in the tank becomes zero using the gas consumption amounts and the future gas consumption amounts for the set number of days. An extracting portion extracts the installation address of the tank for which the remaining amount is predicted to become zero on the day after a second set of days from a set period. A planning portion creates a delivery plan for delivering a new tank to the address extracted by the extracting portion 14 within the set period.
