摘要： PROBLEM TO BE SOLVED: To extremely easily specify the position of a nail when the nail is driven through a concealed metallic flexible pipe by computing the distance from the end of the pipe to the position of the nail based on a measured current or voltage and the electric resistance of a conductive layer. SOLUTION: When a nail is driven through a gas pipe 1 laid in a house at a point P1 , an alternating or direct current is supplied across the pipe 1 and a conductive layer 3 from supplying points 9 and 10 by means of the supplying means 5 of a measuring instrument 4. In the case where the voltage applied across the pipe 1 and layer 3 from the means 5 is 10V, the current becomes zero when no nail is driven through the pipe 1, but when, for example, the electric resistance of the layer is 100Ω/m and the current detected by means of a current or voltage measuring means 6 is 20mA, the resistance of the pipe becomes 500Ω. Since the resistance value of 500Ω is proportional to the distance from the measuring point from which the current is supplied to the point P1 , the calculated distance from the measuring point to the point P1 becomes 5m.

摘要： PROBLEM TO BE SOLVED: To send a same instruction from a radio master set to plural radio slave sets at a higher speed. SOLUTION: A center 1 sends, e.g. a simultaneous interrupt instruction to a radio master set 7. The radio master set 7 sends the simultaneous interrupt instruction to all the radio slave sets 11. The radio slave set 11a sends the interrupt instruction to a meter 13a and receives an interrupt reply from the meter 13a, then sends an interrupt reply to the radio master set 7 in a time Ta after the reception of the simultaneous interrupt instruction from the radio master set 7. The radio slave set 11b sends an interrupt instruction to a meter 13b receives an interrupt reply from the meter 13b, then sends an interrupt reply to the radio master set 7 in a time Tb after the reception of the simultaneous interrupt instruction from the radio master set 7. The radio slave sets 11c,...11n are operated similarly as above. When the radio master set 7 receives the interrupt reply from all the radio slave sets 11, the radio master set 7 sends the simultaneous interrupt instruction to the center 1.

摘要： PURPOSE: To dissolve the time and cost loss of work for a connection confirmation test in the case of installing a meter for automatic meter inspecting by displaying the result of the connection confirmation test on a display part. CONSTITUTION: When a meter 1 for automatic meter inspecting is installed at a consumer of gas, a switch part 7 of the meter 1 is operated. With this operation, a control part 2 originates a call through a communication part 6 to a center and transmits a prescribed telegraphic message to the center. The center, that receives this message, transmits a positive response to the meter 1 for automatic meter inspecting. When the positive response from the center is received, the control part 2 judges the normal end of the connection confirmation test and displays it on a display part 8. Since a worker who installs the meter 1 for automatic meter inspecting observes the contents displayed on the display part 8 so as to recognize the result of the connection confirmation test while staying at the site, the speedy and exact measures can be taken when the connection can not be provided well.

摘要： PURPOSE: To stop a supply of gas to a consumer without making a clerk enter the site of the consumer by providing a gas meter for cutting gas off when a gas cutting-off instruction is transmitted from a radio equipment. CONSTITUTION: The clerk in charge of the gas cutting-off of a gas meter 7 comes near a consumer site 3, carrying radio terminal equipment 8. When the clerk arrives at the destination, the meter ID of the gas meter 7 to cut off gas, the slave equipment ID of slave radio equipment 6 connected to this gas meter 7 and command for instructing the cutting-off of gas are inputted to the radio terminal equipment 8 by operating the keyboard of the radio terminal equipment 8. The clerk transmits a telegraphic message, to which various kinds of information such as the meter ID are set, by pushing a transmission button. The slave radio equipment 6, that receives this telegraphic message, transmits the command for instructing the cutting-off of gas after it is confirmed that the ID set in the telegraphic message is equal with the meter ID of the gas meter 7 to which the slave radio equipment 6 is connected. The gas meter 7, that receives this command, executes the cutting-off of gas.

摘要： PURPOSE: To realize an inexpensive loop antenna having compact, lightweight and simple structure and prevented from being easily broken, and a gas meter using this loop antenna. CONSTITUTION: Two antennas 5a, 5b are connected and fixed on a base 3 by antenna fixing tools 7a, 7b and their periphery is insulated if necessary. The antennas 5a, 5b are approximately half circular arcs and antenna end parts 9a, 9b are opposed to each other with a prescribed interval. The whole antenna 5 is covered with an antenna case 11 made of transparent resin or the like. Since both the antenna end parts 9a, 9b of the antenna 5 are opposed to each other with the prescribed interval, an effect similar to the insertion of reactance is obtained, the antenna can be regarded as a one-point loading capacitor and impedance matching can be attained.

摘要： PROBLEM TO BE SOLVED: To provide a meter such as a gas meter, especially, a meter capable of recording a history of shocks applied from outside.SOLUTION: A sensor 2b extracts a low-frequency component (for example, equal to or lower than 50 Hz) by an LPF 2c (S102), and measures three-axial acceleration values at predetermined sampling intervals (for example, 100 Hz) (S101). The filtered low-frequency component signal is transmitted to a CPU 2a. The sensor 2b normally detects vertical gravity acceleration continuously in a meter installed state, but when the absolute value of the acceleration of the low-frequency component increases above a threshold (corresponding to a first threshold in the claim) (YES at S103), the sensor determines that a shock is applied from outside (S104), receives acceleration values and time data in a certain time before and after that, and saves the data in time series in a memory part 2e (S105). Further, the application of the shock is reported to a center monitoring center 11 (S106).

摘要： PROBLEM TO BE SOLVED: To provide a heat source machine reduced in its installation space and easy to install. SOLUTION: A heat source machine 50 is constituted of a hot water making part A and a metering part B. The hot water making part A is formed as one unit by housing a hot water heat exchanger 31 in a housing 30 and the metering part B is formed as one unit by housing a gas meter 12 and a water meter 14 in a housing 1. The hot water making part A and the metering part B are connected through the pipings of both of them. Since both meters can be collectively arranged by arranging the metering part B, the installation and execution properties are improved and an installation space and the number of members required in installation can be reduced. Further, the heat source machine can be rapidly and easily installed by connecting the hot water making part A and the metering part B.
