摘要： PROBLEM TO BE SOLVED: To provide a charge setting method for averaging monthly payment charge in a predetermined period even when the monthly usage of gas, electricity and water service or the like is different. SOLUTION: In the beginning of a predetermined year starting with a predetermined month, first fixed charge to be paid monthly in one year of the predetermined year is calculated based on at least the total of the payment charge of the previous year of the predetermined year. After the lapse of the predetermined number of months from the beginning of the predetermined year, the fixed charge to be paid each monthly until the end of the predetermined year after the lapse of the predetermined number of months is updated from the first fixed charge to the second fixed charge based on at least one of a difference between the actual usage of every month or charge corresponding to that until the lapse of the predetermined number of months and the actual usage of every month or charge corresponding to that since the start of the previous year until the lapse of the predetermined number of months or predetermined predicted information. After the end of the predetermined year, a difference between the total of charge corresponding to the actual usage of every month in the predetermined year and the total of the charge paid every month in the predetermined year based on the first fixed charge and the second fixed charge is calculated.

摘要： PROBLEM TO BE SOLVED: To provide a gas flow rate detection device (a gas flow rate detection adapter) capable of obtaining a flow rate pulse according to a prescribed gas flow rate by installing the gas flow rate detection device to an existing membrane-type gas meter (a microcomputer gas meter). SOLUTION: This gas flow rate detection device 50 incorporates a magnetic sensor 51 and a signal processing part 52 inside a non-magnetic case. The gas flow rate detection device 50 is installed onto the front face or the upper face of the membrane-type gas meter 30 by bonding or the like. The magnetic sensor 51 detects a change of a magnetic field accompanying movement while drawing a loop-like track K interlockingly with movement of a membrane inside a measurement chamber, of a permanent magnet 8 fixed to a toggle inside the membrane-type gas meter 30. The signal processing part 52 generates and outputs the flow rate pulse on the basis of detection output of the magnetic sensor 51. Without changing the existing membrane-type gas meter for a gas meter with a flow rate pulse output function, the membrane-type gas meter can be made to deal with a system for remote meter reading, remote monitoring, remote management or the like.

摘要： PURPOSE:To reduce a load on a cooling tower, and obtain high temperature recovery water by connecting an exhaust gas pipe of a boiler added to a heat utilizing equipment formed by using high temperature water from a fuel cell to a moisture recovery tower, and connecting a recovery water pipe to the fuel cell. CONSTITUTION:High temperature water C of a fuel cell 1 is supplied to a heat utilizing equipment 4, and a supply circuit from a boiler 5 is connected to the circuit L1. Exhaust gas E of the boiler 5 enters a moisture recovery tower 6, and recovery water F of the tower 6 is connected to the fuel cell 1. Cooling water G of a heat exchanger 7 of the tower 6 is circulated to a coolling tower 9. The exhaust gas E of the boiler 5 is stored in the bottom part as the recovery water F after moisture is condensed by the heat exchanger 7 in the tower 6, and is sent to the fuel cell 1. At this time, as for the exhaust gas E, since an air ratio is low and a dew point is high, a temperature at which the coolling water G goes in and out of the heat exchanger 7 is allowed to be high. Thereby, since a load on the cooling tower can be reduced, high temperature recovery water can be obtained, so that a use can be increased.
