    • The present invention is adapted for providing an idling speed control system of an internal combustion engine, which exhibits a good response for changes in an engine load, comprising: a throttle valve which controls the amount of intake air for the engine; an actuator which includes an electric motor for variably controlling the opening of the throttle valve; a rotation speed detector for detecting the rotation speed of the engine; an idling condition detector for detecting the idling condition of the engine; and a control, responsive to the detected output of the idling condition detector means, for generating feedback control pulses to intermittently drive said electric motor so that the detected rotation speed of the engine under the idling condition may converge into a target idling rotation speed while, responsive to the output of a detector that detects the operation condition of the engine load operated under the idling condition of the engine, or to the detected output of said rotation speed detector indicating that the detected rotation speed has dropped to an abnormally low rotation speed of the engine, for generating drive control pulses at a time independent of said feedback control pulses to drive said electric motor in a predetermined direction.

    • An apparatus for controlling an engine speed through intermittent control of a driving time and a halt time for an engine-speed adjusting actuator (12) in accordance with the output signal of a difference detecting circuit (6) corresponding to the difference between the outputs of a desired speed computing circuit (5) and an actual speed computing circuit (4). The feature of the invention resides particularly in determining the actuator halt time in proportion to the desired quantity of control for the actuator (12) or the engine operation parameter without limiting the said time to any fixed length, hence eliminating overshoot of the engine speed in the control and ensuring satisfactory apparatus capabilities with a short halt time and enhanced response characteristic.

    • The ferrule of the prior art requires an assembling process, high accuracy machining of the fitting portion, machining of the insert to achieve concentricity, machining of the cone and machining of the outer diameter with a high accuracy. This has been making a factor that increases the production cost of the ferrule which is required to have lower price. The present invention provides an ferrule comprising an insert of substantially cylindrical shape that has a fine hole for housing an optical fiber in the axial direction, and an ferrule body made of a resin for accepting the insert fitted therein, characterized in that: the ferrule body has a through hole made in the axial direction thereof, and the through hole communicates with the fine hole of the insert via a tapered hole, with concentricity between the fine hole of the insert and the periphery of the ferrule body being within 10 &mgr;m.

    • A vehicle equipped with four-wheel drive has a transfer case including a center-differential which delivers driving power to both front and rear axle assemblies when needed and is shiftable between a two-wheel and a four-wheel drive mode of operation and between a differential-locked and a differential-unlocked drive mode of operation. A free wheeling drive mechanism with a clutch member is incorporated in an output shaft of an axle differential in association with wheels non-driven in the two-wheel drive mode of operation and is adapted to disconnect when the vehicle is in the two-wheel drive mode of operation. A controller causes a forced drive mode shift of the center-differential from the four-wheel differential-underlined drive mode of operation either to the four-wheel differential-locked or to the two-wheel drive mode of operation when the disconnection of the free-wheeling drive mechanism is detected while the vehicle is in the four-wheel differential-unlocked drive mode of operation.
