Abstract: A laser diode capable of reducing a radiating angle θ⊥ in the vertical direction, an optical pickup device, an optical disk apparatus, and optical communications equipment, all equipped with the laser diode which increases optical coupling efficiency. It has a first cladding layer of the first conductive type formed on a substrate, with an active layer on top of the first cladding layer and a second cladding layer of the second conductive type on top of the active layer. In at least the first or second cladding layer, it is formed of at least one optical guide layer having a higher refractive index than the first or second cladding layer and operating to expand a beam waist in the waveguide. This operation contributes to widening a region in which to shut up light, enabling a radiating angle θ⊥ in the vertical direction to be reduced.

Abstract: A throttle valve control apparatus comprises a throttle valve element supported on a valve shaft, a wire for transferring a force of an accelerator operation part to the throttle valve element, a motor for driving the throttle valve, and a stopper member for transferring a driving force of the motor to the valve shaft. The stopper member has a gear part driven by the motor and a restraint part for restraining an opening degree of the throttle valve. A notch is provided near the restraint part. The driving force of the motor is transferred from the gear part to the stopper member at the time of traction control. The restraint part of the stopper member thus drives the throttle valve element in the close direction. The notch prevents the stopper member from coming in contact with the valve shaft.

Abstract: A control apparatus for electrically operating a throttle valve adapted to adjust the amount of air drawn into an internal combustion engine to adjust the position of the throttle valve. The position and operating condition of an accelerator pedal are electrically detected to generate a signal in accordance with the accelerator position to drive an actuator adapted to operate the throttle valve, and also a desired throttle position established by the signal, the detected actual position of the throttle valve and the operating condition of the accelerator pedal are suitably compared and examined, thus monitoring to see whether the detection of the accelerator position is not faulty, whether the throttle valve is controlled to follow the desired throttle position and so on and thereby performing a safe control by using a substitute desired position upon occurrence of a faulty condition. Also, during the period of acceleration/deceleration, a driving signal is generated to operate the throttle valve to suit the engine operating condition. Further, when the actuator steps out of synchronism, an evacuation control is performed.

Abstract: An intake air quantity control apparatus for use in a motor vehicle for controlling an intake air quantity introduced into an engine of the motor vehicle by controlling the opening degree of a throttle valve provided in an air intake passage of the engine. The intake air quantity control apparatus includes a stepping motor connected to the throttle valve and operatively coupled to an accelerating pedal of the motor vehicle so that the stepping motor drives the throttle valve in response to depression of the accelerating pedal. The stepping motor is arranged to be further controllable in response to a control signal from a control unit of the motor vehicle and thus comprising a stator having a plurality of magnetic poles and a plurality of windings respectively wound around the magnetic poles and excited by the control signal, a first rotor rotatable with respect to the stator in response to excitation of said windings of said stator, and a second rotor disposed between the stator and the first rotor. The second rotor is arranged so as not to receive a rotational torque with respect to the stator in response to the excitation of the windings and to allow transmission of magnetic fluxes from the stator to the first rotor.
