Abstract: This invention constructs within the LAN a private area network (PAN) which is configured by terminal devices (personal computers and the like) of a specific group, is hardly influenced by the LAN traffic, and has high security. For this purpose, a PAN server which manages the communication route between specific terminals is installed within the LAN. The PAN server sets the communication route of each terminal device as label information, and causes switches and terminals to set pieces of label information generated for them. When the frame of data from a given port of each connection switch contains information representing PAN communication, the connection switch outputs the data to only a port specified by routing label information described in the frame.

Abstract: A circuit board according to the present invention is so formed that an extension pattern not covered with an insulating film is provided at a NC land that does not allow an electric signal to pass therethrough, so as to have a configuration equivalent to that of a pattern not covered with the sulating film and provided at a land that allows the electric signal to pass therethrough. Accordingly, the NC land may have an exposed surface area equivalent to that of the land. Therefore, when a semiconductor component is soldered using solders, bumps of the solders at the NC land and at the land may be evenly formed, thereby providing coplanarity of the solders, and increasing soldering reliability for the semiconductor component.

Abstract: An electronic circuit unit contains electrodes to which bumps of a semiconductor chip are adhered. The electrodes are arranged on an upper surface of a circuit board. Land units to which chip parts is soldered are arranged on a rear surface of the circuit board. such that an insulating plate which is on the rear surface of the circuit board is supported by a supporting jig during a mounting process of the semiconductor chip, and the circuit board is not tilted. Therefore, an electronic circuit unit ensuring that the semiconductor chip is mounted with a reliable mounting capability can be obtained.

Abstract: When an incoming call to a wireless communication apparatus is detected, a wireless control apparatus uses a wireless link, which has been established by previous communication, to perform succeeding communication. Examples of communication include communication of audio or data already completed, or, when there are a plurality of wireless communication apparatus, communication of control information by a wireless link established when notification of an incoming call is given to the wireless communication apparatus.

Abstract: A electronic circuit module of the present invention comprises a circuit board 1 formed with laminated plurality of insulating sheets, and a cover 9 made from a metal plate and having attaching legs 9c soldered to electrode portions 7 in the concave portions 1c in a state of covering the electronic component 8. The concave portions 1c are formed from an upper surface of the circuit board 1 toward a lower surface side, stopping portions 1d for plugging the lower portions of the concave portions 1c are provided in the circuit board 1, and the attaching legs 9c of the cover 9 are soldered to the electrode portions 7 in a state of being inserted into the concave portions 1c. As a result, it is possible to prevent the soldering connecting the attaching legs 9c to the electrode portions 7 from leaking downward by way of the stopping portions 1d.

Abstract: An electronic unit includes a module in which a semiconductor device is attached on the bottom of a circuit board and which has lands provided on the bottom of the circuit board, and a printed circuit board on which the module is mounted, the printed circuit board having a hole in a position facing the semiconductor device and having electrical conductors to which the lands are soldered. The module is mounted on the printed circuit board by soldering the lands to the electrical conductors while the semiconductor device is disposed in the hole. Accordingly, the electronic unit is smaller in height than conventional electronic units. Such a structure allows the module to be surface-mounted on the printed circuit board with solder paste, and thus high productivity of the electronic unit can be achieved.

Abstract: The invention provides an optical cable closure of which outer casing is made by joining two half cases on a partition plane and can be made smaller, with no redundant space produced in either of the half cases. A plurality of cable leading holes 4 are provided on only one end of a two-partition type outer casing 1 comprising half cases 1A and 1B of an identical configuration, with the cable leading holes 4 being arranged side by side and divided into halves by a partition plane 5 of the outer casing 1. Plugged into each cable leading hole 4 and supported therein is an end plate 6 which fits around the circumference of the optical cable 3 and seals the cable leading hole 4. The end plate 6 has a cable passing hole 6a disposed offset from the center line and is aligned in the cable leading hole 4 so that the offset cable passing hole 6a is disposed closer to the bottom side than the partition plane inside one half case 1A.
