Abstract: Both ends of a plurality of parallel electrical wires are respectively connected to the connectors with pressure by a pressure-connecting and wiring machine into which the plurality of electrical wires are introduced, and the thus introduced electrical wires are sent to the electrical wire pressure-connecting section via the electrical wire cutting section. At this time, the connectors are successively fed to the electrical wire pressure-connecting section of the pressure-connecting and wiring machine in the direction parallel with the arrangement of the pressure terminals. After the electrical wires have been connected to the connector with pressure, the pressure-connected electrical wires of a predetermined length are drawn out from the pressure-connecting and wiring machine. Then the pressure-connecting and wiring machine is turned round the vertical axis by an angle of 180.degree., and the electrical wires, which have been drawn out before, are connected to the other connector with pressure and cut.

Abstract: A microcomputer 4 responds to an instruction signal to turn the load L on or off to control the FET 2 through the drive circuit 5. The microcomputer 4 samples an electric current I.sub.L which is supplied through the A/D converter 6 and which flows in the load L at every predetermined sampling time T.sub.S and subjects the sampled electric current I.sub.L to a comparison with a known rated current value I.sub.R for the load L. When I.sub.L .gtoreq.I.sub.R is satisfied, the microcomputer 4 starts counting energizing time T. When the accumulated value of I.sub.L .times.T.sub.S is enlarged to a predetermined value S.sub.O, the microcomputer 4 turns the FET 2 off. When the detected electric current I.sub.L is larger than an upper limit I.sub.O (>I.sub.R) determined previously, the microcomputer 4 immediately turns the FET 2 off through the drive circuit 5.

Abstract: In the vehicle antenna, a GPS antenna, a radio wave beacon antenna for VICS/automatic rate, and an optical beacon antenna are incorporated into between the mirror of a room mirror and a cover and they are united together into an integrated body. The vehicle antenna is structured such that it is allowed to transmit and receive signals with respect to a GPS, a VICS/automatic rate beacon, and an optical beacon through the windshield of a vehicle. This structure eliminates the need to install the respective antennas of the vehicle antenna onto a vehicle body and an instrumental panel, thereby being able to improve the appearance of the interior of the vehicle. Also, since the vehicle antenna is incorporated in the room mirror, the vehicle antenna is not visible directly to the eyes of a driver and is kept from reflecting its shade into the windshield to thereby prevent interference with the driving operation of the driver.
