    摘要: An audio speaker configured for simple manual or automatic robotic insertion into an enclosure aperture so that it will be electrically connected to an audio signal transmission medium and retained within the enclosure. The speaker includes a latching mechanism and a pair of coplaner electrically conductive contact pads concentrically oriented and disposed on the back of the speaker. The pads are disposed so as to contact a pair of relatively fixed electrical terminals mounted on the enclosure, independent of any rotational orientation of the speaker.

    摘要: An apparatus for controlling the operation of an engine based on the pressure in an intake manifold. If a change in the pressure in the intake manifold is equal to or less than a predetermined value during a predetermined period within the period from the time when a voltage source is turned on to the time when a starter is turned on, the pressure in the intake manifold is detected and stored. If the engine is not in the start mode, the rate of fuel supply is increased based on an atmospheric pressure detection value. Based on the comparison between the atmospheric pressure value and a predetermined value, a passage for bypassing a throttle valve is opened and closed to control the idling of the engine.

    摘要: 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.

    摘要: A fuel injection device for an automotive internal combustion engine is disclosed, which comprises two distinct acceleration state determining means, i.e., a rapid and a slow acceleration state judgement means, for determining the amount of the asynchronous augmentation of fuel. The rapid acceleration state judgement detects the rapid acceleration state by comparing with a first threshold level the increment of the throttle opening degree over each period of an A/D conversion timing signal; the slow acceleration judgement means, on the other hand, detects the slow acceleration state by comparing with a second threshold level the increment of, for example, the throttle opening degree signal over, for example, two successive periods of the same A/D conversion time signal. When the rapid acceleration state is detected, an asynchronous augmentation of fuel for the rapid acceleration is effected. On the other hand, an asynchronous augmentation of fuel for the slow acceleration is effected only if: (1) the rapid acceleration state is not detected, and (2) the slow acceleration state is detected, over the two successive periods of the timing signal.
