    摘要: A switching apparatus for constructing a system integrating a telephone switching network and a LAN includes: line interface sections, each connected to a transmission line for transmitting a signal on which low-speed data and high-speed data are multiplexed; a low-speed data switch for switching low-speed data demultiplexed in each line interface section; a high-speed data switch for switching high-speed data demultiplexed in each line interface section; and a processor for monitoring and controlling the data traffic passing through the low-speed data switch and high-speed data switch. An address in a designated position in the high-speed data demultiplexed in each line interface section is read out, whereby the association between the low-speed data terminal and high-speed data terminal is identified and stored. By referring to this association, management of LAN terminals can be performed using the maintenance operation procedures used in a conventional electronic switching apparatus.

    摘要: A rotary connector includes a case, a cover, a rotor having a top panel part and a first cylindrical part, a rotor snap having locking parts locked with an outer surface of the cover and a second cylindrical part snap-fitted to the first cylindrical part, flexible cables wound windably/rewindably in the case, and a ring-shaped plate part. In this case, a holding projection project outward in a radial direction from the outer circumferential surface of the second cylindrical part between a lower end of the first cylindrical part and the locking parts, and an inner rim of the cover is provided with a holding step so as to form a step. Furthermore, a wall surface forming the step of the holding step faces side surface of the holding projection, and an inner rim of the cover is rotatably interposed between lower surface of the holding projection and an upper surface of the ring-shaped plate part.

    摘要: A motor-driven power steering apparatus includes a motor for generating assisting force to be imparted to a steering mechanism, a control signal generation section for generating a motor control signal on the basis of at least steering torque applied to a steering wheel, a motor drive unit for driving the motor in accordance with the motor control signal, and a step-up circuit provided between a battery to the motor drive unit. The step-up circuit includes a step-up coil whose one end is connected to the battery, a first switching element connected between the other end of the step-up coil and the ground, a second switching element connected between the other end of the step-up coil and an output terminal, and a capacitor connected between the output terminal and the ground and smoothing output voltage appearing at the output terminal. The apparatus further includes a step-up circuit control unit which detects the output voltage and controls the first and second switching elements on the basis of difference between a target output voltage and the detected output voltage. During power generation periods, at least the first switching element is turned on and off in order to increase the output voltage supplied to the motor through step-up operation. During regeneration periods, at least the second switching element is turned on and off.
