摘要： A method of inspecting an abnormality occurring inside a pipe to be inspected and an apparatus for practicing the method, includes the steps of transmitting an electric wave having a predetermined frequency from an antenna of a transmitter located at a predetermined position inside the pipe, receiving the transmitted electric wave by an antenna of a receiver located at a predetermined position inside the pipe, and discriminating the characteristic of the received electric wave. The characteristic of the received electric wave is the intensity of the electric wave, and an attenuation amount is detected in the first example. On the other hand, the characteristic of the received electric wave is a time required to reflect the transmitted electric wave until it is received by the receiver, and a time interval between transmission of the electric wave and reception of the reflected electric wave is measured in the second example.

摘要： A method of measuring the inner diameter of a pipe, includes the steps of continuously transmitting electric waves in a predetermined frequency band from an antenna of a transmitter located inside of the pipe to be inspected, receiving the electric waves by an antenna of a receiver located inside the pipe, the antenna of the reciver being spaced apart from the antenna of the transmitter by a predetermined distance, detecting a frequency at a change point where an intensity of the received electric wave changes greatly, substituting the frequency at the change point into a formula: d=c/1.706f (where d is the inner diameter of the pipe, c is the velocity of light, and f is the frequency of the change point) which shows the relation between the inner diameter of the pipe and the frequency to obtain a minimum inner diameter of the pipe.

摘要： PROBLEM TO BE SOLVED: To avoid reductions in convenience in the use of a gas appliance due to the exceeding of a maximum amount of change held by a gas shut-off device over a total gas consumption. SOLUTION: The gas shut-off device includes a flow rate detection part 11, a flow rate calculation part 12, an increase and decrease calculation part 13, an increase and decrease determination part 14, a valve driving part 15, a valve 16, and an isolation correction part 17. The increase and decrease determination part 14 deletes a change amount C once held by the gas shut-off device on the basis of a correction request signal G determined by the isolation correction part 17 and registers an actual flow rate of gas as a new change amount C to prevent the period of time of gas use until the closing of a gas passage from being shortened on the basis of an unrealistic change amount C.

摘要： PURPOSE: To attain a wireless system for an automatic metering system without revision of a specification of each equipment in an existing automatic metering system utilizing radio communication. CONSTITUTION: A 're-transmission request text' is stored in a dummy text storage means A6. A timer A5 starts measurement when a text transmission reception means A3 receives a text and finishes the measurement when a radio signal transmission reception means A4 receives the text. If the timer time is almost up before the text transmission reception means A3 receives the text from the radio signal transmission reception means A4, the timer A5 informs it to the dummy text storage means A6. Upon the receipt of a signal from the timer A5, the dummy text storage means A6 sends the 're-transmission request text' stored therein to a microcomputer meter. On the other head, a radio communication means B13 at a terminal equipment side is operated similarly.

摘要： PURPOSE: To easily perform the registration of a slave equipment. CONSTITUTION: The registration of the slave equipment is performed by transmitting a slave equipment registration signal from an automatic gas meter 6 side via the slave equipment 5, and performing communication between a radio master equipment 4 or 4a set in such relation proportional to the inverse of communication wave strength. The radio master equipment 4 or 4a receiving such slave equipment registration calls a managing center 1, and registers the IDs, equipment numbers of the automatic gas meter 6 and the radio master equipment 4 or 4a, etc. The managing center 1 confirms the communication by calling the automatic gas meter 6 after such registration is completed.

摘要： PURPOSE: To shorten the delay time of transmission and to improve the efficiency of communication by receiving a succeeding original telegraphic message with prescribed length while transmitting a telegraphic message with prescribed length out of an original telegraphic message from a certain radio equipment to another radio equipment at the time of sending the original message from a communication equipment to the radio equipment concerned. CONSTITUTION: In an automatic gas gauge examination communication system 1 e.g. a center 3 is connected to a public line 7 through a C-NCU 5 a T-NCU 9 connected to the line 7 switches between a telephone set 11 and a radio equipment 13, and at the time of executing automatic gauge examination, a microcomputer meter 17 is connected to the center 3. Radio communication is executed between plural radio equipments 13, 15 connected between the T-NCU 9 and the meter 17. When an original telegraphic message from the center 3 is sent to the T-NCU 9 through the C-NCU 5 and the line 7 and the T-NCU 9 sends the message to the radio equipment 13, a CPU in the equipment 13 adds a radio header and a redundant code to the message at the time of receiving the message with prescribed length, transmits the added message to the equipment 15 and receives a telegraphic message with prescribed length out of the original message.
