摘要： PURPOSE:To facilitate the installation of an antenna and to cancel radio wave faults caused by the shadow of the building by installing a conductor as the antenna for high frequency on the outer wall surface or the surface of the window of the building so as to radiate or absorb radio waves with the conductor. CONSTITUTION:A conductor 3 is embedded in an outer wall panel 2 (insulated object) of the building and in the building inside direction of the outer wall panel 2, as a reflector 4, a metal board or metal mesh is fitted and grounded. When radiating radio waves, a voltage is impressed between terminals 3a and 3a of the conductor 3. Thus, the radio waves are radiated from the conductor 3 to the front direction of the outer wall surface of the building. When receiving radio waves, the radio waves are absorbed by the conductor 3. In this case, since the place of antenna installation is not selected, the antenna installation is facilitated. When using the building for mobile object communication, it is possible to increase the number of antennas to be installed, and area division can be made fine. On the other hand, at a building in the shadow of that building, radio wave faults are canceled.

摘要： PURPOSE:To facilitate antenna construction, to increase the valueadded of the building and to effectively utilize the land by arranging a conductor along the height-wise direction of the entire building and radiating or absorbing radio waves with the conductor while using that conductor as an antenna. CONSTITUTION:Wire-shaped conductors 4 as antennas are vertically fitted to four outer wall surfaces 3 perpendicular to a land 2 of a superhigh building 1 in the state of being insulated from the outer wall surfaces 3. An antenna base 5 is provided on the outer wall surface 3 in contact with the land 2 and insulated from the lower edge part of the conductor 4 by insulator 6. The antenna base 5 is grounded under the building by a ground line 7. When radiating radio waves, a voltage is impressed between the conductor 4 and the antenna base 5. Thus, the radio waves are radiated from the conductors 4 to the four directions of the superhigh building 1. When receiving radio waves, the radio waves are absorbed from the four directions by the conductors 4.

摘要： PURPOSE:To surely detect a fault position and to improve the reliability and the maintenance operation performance by obtaining a phase difference between a traveling wave and a reflecting wave of an antenna system. CONSTITUTION:A traveling wave Pf and a reflecting wave Pr from a directional coupler 3 are fed to a VSWR detection section 12 via a distributer 5, after each level is converted into a VSWR, the result is fed to a computer 13. The computer 13 controls a synthesizer 6 to calculate a distance up to a reflecting point based on a phase difference between the traveling wave and the reflecting wave at each frequency and to display the result. Thus, a fault location is located, a fault restoration time is reduced to improve the reliability and the maintenance operation performance of the antenna.

摘要： PROBLEM TO BE SOLVED: To obtain a method and an apparatus in which a temperature can be detected without being influenced by an external environment, which can be used irrespective of the shape of a power-supply system and in which a degradation place can be specified by a method wherein a temperature sensing means is housed at the inside of a coaxial-feeder connection part and a magnetic-field sensor is installed at the connection part. SOLUTION: An external conductor 8a and an external conductor 8b at a coaxial feeder are connected to each other by a coupling 10 and a hose band 11. An internal conductor 9a and an internal conductor 9b are connected to each other by an inner connector 1. A housing pipe 3 is housed inside the inner connector 1. On the other hand, when a magnetic-field sensor 12 is attached to the coupling 10, it is arranged on the outside of the external conductors. A signal line 13 fetches the output of the magnetic-field sensor 12. Since the temperature at the inside of their connection part is detected by this method, the temperature can be detected without being influenced by an external environment. In addition, since a change in a magnetic-flux density generated by a temperature is detected, the method can be used irrespective of the shape of a power-supply system. In addition, since the method can be applied independently for every connection part, it is possible to specify a degradation place even when many connection parts exist.

摘要： PROBLEM TO BE SOLVED: To fit a connector to a coaxial cable at one touch. SOLUTION: After a fastening fitting 101 is fitted onto a coaxial cable 107 and the fastening fitting 101 is fastened onto the coaxial cable 201, the same is inserted into a main body 107. A nut 106 provided on the main body 107 and the fastening fitting 101 can be mutually screwed, the fastening fitting 101 and the coaxial cable 201 enter the inside of the main body 107 as a screwed state is strengthened. In a process in which the screwed state is strengthened, the cutter of a cutter collar 108 bites into the outside conductor 204 of the coaxial cable 201 so as to be electrically connected thereto, and the tip face of a push pin 111 comes into pressure contact with the inside conductor 202 of the coaxial cable 201 so as to be connected thereto.

摘要： PURPOSE: To provide a two-dipole panel antenna which is equipped with simple structure and can change a matching frequency with a simple operation. CONSTITUTION: The parts of the roots of both V-shaped arms 1a and 1b, which can be strentched at a fixed opening angle, are fixed on a reflection panel 2 and two stretchable dipole elements 3a and 3b are respectively parallelly fitted to both the arms 1a and 1b. Then, two parallelly fitted dipole elements 3a and 3b are connected by parallel lead wires so that their phases can be opposite each other, and one end of the parallel lead wires is defined as a feeding point. Thus, only by stretching the dipole elements 3a and 3b and both the V-shaped arms 1a and 1b and segmenting and connecting one of parallel lead wire of a 1/2 wavelength, a prescribed frequency can be matched and an adjusting operation is simplified.
