摘要： PURPOSE:To inspect the state on the inside of a pipe accurately by transmitting radio waves into the pipe and detecting abnormality, e.g. clogging of pipe, based on the attenuation of transmitted radio waves. CONSTITUTION:Meters 6 are selected at two points on the opposite sides of a point to be inspected and then a service pipe 4 is removed. The antenna 13 of a transmitter 12 is then inserted into the service pipe 4 from one open end thereof until a branch pipe 2 is reached. Similarly, the antenna 19 of a receiver 14 is inserted from the other open end of the service pipe 4 up to the branch pipe 2 thus disposing the antennas 13, 19 on the opposite sides of a point to be inspected of the branch pipe 2. A transmitter 12 then transmits radio waves having frequency equal to or higher than a frequency determined by dividing the speed of light by 1.706 times the inner diameter of pipe. The radio waves are is transmitted 12 while varying the frequency continuously within a predetermined frequency band. The radio waves transmitted through the branch pipe 2 is then receives 14 and the strength thereof is compared with that of the transmitted 12 radio wave thus detecting the attenuation. It is corrected based on the attenuation dependent on the distance between the antennas 13, 19 and the corrected value is displayed thus inspecting the inner state of the branch pipe 2.

摘要： PURPOSE:To discriminate display contents of plural areas on a screen by providing a deciding means which decides area and their colors when the number of the extracted colors exceeds a specific threshold value and discriminating the display contents of the areas with the decided colors. CONSTITUTION:A display 1 is divided into plural areas 3, whose display contents are shown with colors. Here, Ak (k=1-N) is a pointer indicating a pixel in the areas. A memory 5 is stored with the colors of points on the display 1, namely, color data (red R, green G, and blue D) for the points (xi, yi). A program 6 showing processes of this display contents discriminating device repeats S7 for extracting the color data (R, G, and B) at plural points (xi, yi) (j = 1-x) in the areas, S11 for specifying the color of the area to the color when the number of points showing one color in the area exceeds the specific threshold value S9, and S7 and S9 when the number of the points showing one color in the S9 does not exceeds the threshold value.

摘要： PURPOSE: To clarify a reflection echo from an object by decreasing the side gain (direction gain of both transmissionand reception antenna) of both the transmissionand receptionantenna so as to improve the directivity.
CONSTITUTION: A ferrite 3 mounted on a n antenna element of both triangle dipole type transmission and reception antennas 1, 2 is made of a specific size sintered plate and mounted only at a position near a feeding part 6 for light weight. A transmission antenna 1 and a resistance wire R-1 are placed in the same plane and a reception antenna 2 is placed in the right direction. The electric field in the direction of the reception antenna 2 depends on an output of the transmission antenna 1, a self impedance Z
22 of the resistance wire R-1 and a mutual impedance Z
12 between the transmission antenna 1 and the resis tance wire R-1 and it is required for the provision of the shield effect in the direction of the reception antenna 1 to provide nearly the same value to the Z
12 and Z
22 (including their signs).

摘要： PROBLEM TO BE SOLVED: To perform prepaid online settlement for use fees of equipment by using a portable terminal and to further control the equipment directly from the portable terminal. SOLUTION: A user performs payment 31 (prepaid) for the use fees of a gas meter 13 to a financial institution 19 from the portable terminal 7-1 via a network 5. A center 3 to receive notification of payment from the financial institution 19 downloads a program 33 including information regarding valve opening and use time of the gas meter 13 to the portable terminal 7-1. The portable terminal 7-1 starts up the program 33 and transmits a valve opening instruction to the gas meter 13 connected by short-coverage radio communications or a cable. The valve of the gas meter 13 is opened and the center 3 transmits notification to the portable terminal 7-1 when the use time is limited.

摘要： PROBLEM TO BE SOLVED: To provide a load survey meter system which obtains load survey information of high precision and is simple in data processing. SOLUTION: When gas equipments 13 (13-1 to 13-n) start or stop operating, radio equipments 17 (17-1 to 17-n) on the sides of the gas equipments 13 send operation state information to a radio equipment 15 on the side of a microcomputer meter 3. The radio equipment 15 on the side of the microcomputer meter 3 receives the operation state information sent from the radio equipments 17 and sends it to the microcomputer meter 3. The microcomputer meter 3 generates gas consumption information from the amount of used gas passing through the microcomputer meter 3 and records the operation state information and gas consumption information at previously set intervals of time. The recorded operation state information and gas consumption information are sent to a center 11.

摘要： PURPOSE: To revise a direction of a supervisory equipment in a way that an intruder cannot predict by moving the supervisory equipment in a chaos way based on a chaos signal. CONSTITUTION: A chaos signal outputted from chaos signal generating circuits 2, 3 of a supervisory equipment driving device 1 is fed to a driver 8 via corresponding A/D converter and BPFs 4, 6 and 5, 7 and the supervisory equipment 10 is moved in terms of chaos via a servo motor 9 and its direction is revised. Through the revision of its direction in a chaos way, an intruder cannot predict the direction of the supervisory equipment and the intruder cannot get through against the supervisory equipment. Furthermore, the chaos signal generating circuit is easily configured by using nonlinearity of the circuit and the direction change of the supervisory equipment is moved smoothly and continuously by the control of the chaos signal and a load imposing onto the drive system is reduced.
