Abstract: PROBLEM TO BE SOLVED: To detect easily the level of an interfering wave and the direction of an interfering source without cutting a cable, concerning the electromagnetic interfering wave generated from the cable between electronic apparatuses. SOLUTION: First of all, a non-equilibrium type interfering wave detector 10 is arranged on a position close to a cable 33, so that a resistor 14 is positioned on the first device 31 side, and the intensity xdB of an interfering wave detected at that time is observed by a measuring device 18. Then, the non-equilibrium type interfering wave detector 10 is arranged on a position close to the cable 33, so that the resistor 14 is positioned on the second device 32 side, and the intensity ydB of an interfering wave detected at that time is observed by the measuring device 18. And the difference xdB-ydB between the two interfering wave intensities xdB, ydB is obtained. As the non-equilibrium type interfering wave detector 10 functions as a directivity coupler relative to the cable 33, it is judged that, if the difference xdB-ydB is positive, the interfering wave flows out of the first device 31, and that, on the contrary, if the difference xdB-ydB is negative, the interfering wave flows out of the second device 32.

SOLUTION: The high-frequency current detecting device is a device to detect high-frequency current flowing through a conductor and is constituted by including a hollow core 4 made of ferrite, the first and second conductive bodies 6 and 8, and a resistor 10. The first conductive body 6 is formed of band plate- shaped conductive material and is inserted into the hollow part 12 of the core 4, and its both end parts 14 are protruded from the hollow part 12 to form probe parts 16. The second conductive body 8 is formed of band plate-shaped conductive material and is inserted into the hollow part 12 of the core 4, and its both end parts 18 are protruded from the hollow part 12 and are opposingly arranged at an interval between them outside the core 4. The second conductive body 8 is electrically insulated from the first conductive body 6 by providing an interval between them in the hollow part 12. The resistor 10 is arranged between both end parts 18 of the second conductive body 8. A voltmeter is connected to both end parts 18 of the second conductive body 8 via lead wires 20 to measure the voltage of both ends of the resistor 10.

Abstract: PURPOSE:To provide a highly sensitive, wide band, and stable mobile antenna without obstructing the field of view of a driver or crew. CONSTITUTION:Feeding section 14 is installed on the back of a back miller 1 inside of a car so that feeding section 14 and a feeder 11 are out of the field of view of a driver or crew. Next, fine line is used for antenna elements 6, 9, and 10 that are extended from the feeding section 14 so as not to obstruct the field of view of the driver or crew. Here, by extending antenna elements from the position of the back mirror 1, these antenna elements are separated from metallic section of a window, thereby being able to improve the sensitivity of the antenna, and further the use of three antenna elements enables the antenna to cover a wide band. Furthermore, the feeder 11 and feeding section 14 are provided with balun 12 to protect the sensitivity characteristic of the antenna from becoming unstable by pulling around the feeder 11 or the like.

Abstract: PURPOSE:To excellently receive a secondary radiation radio wave from a wire, to miniaturize the configuration and to simplify it by installing a bar antenna fitted to the body of a vehicle driven in a direction along the overhead line so that its core axis of a high frequency magnetic core is set in parallel with the wire. CONSTITUTION:Bar antennas 1-6 fitted to the vehicle body 20 of a vehicle receiving power from the wire and driving in a direction along the wire are provided and the core axes of high frequency magnetic cores 7 of the bar antennas 1-6 are set in parallel with the direction A of the wire. Thus, the bar antennas 1-6 receive excellently a secondary radiation radio wave from the wire. Then the bar antennas 1-6 do not receive sliding noise caused between the wire and a contact coming into contact with the wire to receive the power from the wire and have omnidirectional reception sensitivity. Thus, the excellent reception sensitivity is realized while miniaturizing and simplifying the structure.

Abstract: PURPOSE:To prevent the occurrence of malfunction of the system by connecting a conductor insulated in terms of high frequencies and an output side of a monopole antenna to a tuner via a balun. CONSTITUTION:A conductor 12 insulated in terms of high frequencies is provided in an enclosure 10 in addition to a circuit ground 14. The conductor 12 acts like another antenna element corresponding to a monopole antenna 11. The conductor 12 and the output of the antenna 11 are connected to a tuner 15 via a balun 13. A displacement current from the ground pattern 14 having a disturbing source (e) is going to flow to the antenna 11 and the conductor 12 through the balun 13, but the impedance between terminal S-E and P-F in the common mode gets higher. Thus, no displacement current flows to the antenna 11 and the conductor 12, the occurrence of beat disturbance onto a television picture and of beat disturbance onto a ground signal is prevented.

Abstract: PURPOSE:To improve the use effect of the selection operation of programs by displaying a receiving program and a program selected by a user himself and simplifying the selection operation of the program selected by the user. CONSTITUTION:Receiving signals where plural static signals formed during a prescribed number of horizontal scanning periods are superposed successively in a fixed section of the vertical period for every fixed period are received, and static picture signals are extracted from these receiving signals, and these extracted signals are stored in a memory circuit, and signals stored in this manner are read out successively to project an arbitrary program of receiving programs. The selective read of a TV multiplex broadcast receiving unit like this is performed by reading out successively alphabets added to programs stored in ROM 28 on a basis of the result of the comparison between gate signals from gate circuits 24 and outputs of selection circuit 16 and decoder 15 in comparator circuit 26, and these alphabets are applied to synthesizer circuit 31 through shift register 30 where timing signals are inputted, and receiving program P and program G selected by a user are displayed simultaneously by the output of circuit 31.
