Abstract: An audio apparatus comprises a tuner for receiving broadcast waves; a digital reproducing unit; operation switches for operating the tuner and the digital reproducing unit; and a control unit for controlling the tuner and the digital reproducing unit in response to an operation of the operation means. In a first mode of operation, the control unit controls if an audio signal from the tuner is selected as a source such that the power of the digital reproducing unit is turned on, and wherein, in a second mode operation, the control unit controls if an audio signal from the tuner is selected as a source such that the power of the digital reproducing unit is turned off, alternatively if an audio signal from the digital reproducing unit is selected as a source, the power thereof is turned on.

Abstract: A connector for a coaxial cable has a connector body and a securing ring. The connector body includes a tubular insertion section that is insertable between an insulation member around a core conductor of the coaxial cable and a woven conductor around the insulation member, a flange section that is provided around the insertion section and with which both the woven conductor of the coaxial cable and a cover member around the woven conductor come into contact when the insertion section is inserted in the coaxial cable to position the insertion section, and an annular fitting section that is provided at the insertion section, on the opposite side of the coaxial cable, and into which an object to be connected is insertable. The securing ring is used to pressure-bond and fix the coaxial cable to the insertion section from the periphery of the coaxial cable after the insertion section of the connector body is inserted in the coaxial cable.

Abstract: A series unit comprises an input terminal and an output terminal each composed of a tubular receptacle having a center conductor and an external conductor provided concentrically with the center conductor, a television terminal, and a unit case for supporting the input terminal, the output terminal, and the television terminal. The external conductors of the terminals are electrically interconnected through the unit case. The center conductors are electrically interconnected in the space defined inside the unit case. The orientation of the connection end portion of the unit case is perpendicular to the connection/disconnection end portion to/from which the terminal of the cable is connected/disconnected. The input terminal and the output terminal are constituted as movable terminals rotatable at the connection end portions of the unit case. The planes defined by the center axes of the connection/disconnection end portions by the rotation of the movable terminals are perpendicular to each other.

Abstract: The invention provides a noise elimination device that can be installed easily on a coaxial cable and that can effectively eliminate noise from both the center conductor and the outer conductor. Coaxial connectors 2 and 3 are provided on both ends of a tube-shaped housing 1 made of an insulator, and a coil made by winding a coaxial cable of thin diameter is around an open magnetic ferrite core is disposed inside the housing 1 and connected to the connectors 2 and 3 at the two ends. The earth-side connector thickness of the outer conductor of the coaxial cable and the connector as well as all earth-side conductors, such as shield members 7 connecting the connectors with the outer conductors of the coaxial cable, is at least 0.1 mm.

Abstract: A cable broadcasting system having a simple structure, by which radio telephones can be used in good condition even inside a building, or at any other place where a subscriber's terminal is provided. An existing community receiving system for supplying, to a subscriber's terminal installed in each subscriber's home, broadcasting signals (90-1335 MHz) in VHF, UHF, and BS-IF bands received by respective outdoor antennas is provided with another outdoor antenna for radio waves in a radio telephone frequency band (1429.025-1919.45 MHz) used for cellular phones and PHS terminals, and a radio telephone repeater for transmitting/receiving the radio waves in the radio telephone frequency band. Furthermore, a head end unit in the system is provided with a mixer-extractor such that the signals transmitted/received by the radio telephone repeater can be relayed, via a tap device, to the subscriber's terminal.

Abstract: A series unit capable of easily changing over a undirectional state to/from a bidirectional state and easily judging which state the series unit is in, is provided. A high pass filter 9 and a changeover switch 5 are included, and an operating protrusion 5a of the changeover switch 5 is provided in a circular recess 10 of a panel 2 formed to surround an F-type terminal 4 provided on a front surface. A cylindrical adapter 6 inserted into the circular recess 10 is provided so as to operate the operating protrusion 5a. The adapter 6 has a notch 6a which is provided on one side portion of the adapter 6 and which does not press the operating protrusion 5a. By inserting the adapter 6 while rotating the adapter and changing an angle, a unidirectional state can be changed over to/from a bidirectional state. In addition, a mark 16a indicating a position of the operating protrusion 5a is provided on the panel 2 and a mark 15 indicating a notch position is provided on an end portion on a front surface of the adapter 6.
