摘要： A nonreciprocal circuit device miniaturized entirely by reducing the height and the weight can prevent characteristic deterioration. In the nonreciprocal circuit device, a ferrite assembly is formed by winding a quadrangular ferrite plate with insulated copper wires mutually intersecting. The ferrite assembly is arranged perpendicularly to the mounting surface of a mounting substrate. On each side of the ferrite assembly, there is arranged a magnet applying a static magnetic field perpendicularly to main surface of the ferrite plate.

摘要： A nonreciprocal circuit element having low insertion loss is provided. In the circuit element, three central conductors are disposed such that they intersect each other at specified angles in an electrically isolated condition and a DC bias magnetic field is applied to the intersection. The intersection angles formed by the central conductors are set to different values, corresponding to the rotation angle of the high-frequency magnetic field caused by the DC bias magnetic field. A stronger operating DC magnetic field than that in a conventional circuit element is used to reduce a ferrite loss.

摘要： In a coaxial connector, signal lines are switched over by mounting and dismounting a probe having a central contact, and fixed yoke terminals, a movable terminal, and a permanent magnet constitute a magnetic circuit. When the probe is dismounted, the contact portions are connected by the magnetic force of the permanent magnet. When the probe is mounted, the contact portions are disconnected against the magnetic force such that the central contact pushes a protrusion portion of the movable terminal.

摘要： An antenna-integrated strip line cable with which it is possible to improve the performance of a high-frequency appliance such as a portable telephone without making the appliance larger. An antenna-integrated strip line cable 1 is made up of a transmission line part 2, an antenna part 3 and a counterpoise 4. The transmission line part 2 is made up of two conductors 21, 22 disposed in parallel, insulators 23, 24 having plasticity or flexibility disposed between these two conductors 21, 22, and a central conductor 25 disposed between the insulators 23, 24 centrally in the width direction thereof. Wide-pattern impedance matching circuits 26a, 26b are provided in the central conductor 25. The antenna part 3 has portions of the insulator 24 and the central conductor 25 extending from the transmission line part 2. The counterpoise 4 has portions of the insulator 23 and the conductor 21 extending from the transmission line part 2. The counterpoise 4 is perpendicular to the antenna part 3 and the length of the counterpoise 4 is about one-fourth of the wavelength .lambda. of the frequency used. Some benefits of this novel construction are that the number of parts is reduced, the work of connecting a coaxial cable to an antenna is made unnecessary, the counterpoise reduces directivity of the antenna part, the antenna is tough, and it is not necessary to provide an impedance matching circuit externally.
