Title: Control device for internal combustion engine
Inventor: ICHIHARA HIDEAKI
IPC: F02P5/15
Filed: 2000-09-27
Abstract: PROBLEM TO BE SOLVED: To improve the follow-up controllability of the rotational frequency by increasing the quantity of fuel when an internal combustion engine is started and to prevent deterioration of the emission and fuel efficiency of the engine. SOLUTION: The quantity of fuel injection fed to the internal combustion engine 1 is increased/corrected only when the deviation of rotational frequency between a target value and the actual rotational frequency is a prescribed value or larger and the ignition time F/B variable is a prescribed value or larger during a prescribed period of time from the start of the internal combustion engine. Especially in case of a heavy gasoline, etc., which has low volatility at the time of cold start of the internal combustion engine 1, the quantity of fuel is increased only when the actual rotational frequency is excessively declined or the increase of the actual rotational frequency is too slow relative to the target rotational frequency. Accordingly, the follow-up controllability of the actual rotational frequency relative to the target rotational frequency at the start of the internal combustion engine 1 is improved, and since the quantity of fuel is not increased when the decline of the actual rotational frequency can be inhibited by controlling the ignition time F/B control at the start of the engine, deterioration of the emission and fuel efficiency of the engine can be prevented.

Filed: 2000-10-20
Abstract: PROBLEM TO BE SOLVED: To provide an image pickup device in which a lens barrier is positioned within a window section when the lens barrier is in a close position. SOLUTION: A compression spring 168 is disposed between an external case and an arm 150 on which the lens barrier 38 is set, and forces the arm 150 in the direction away from the external case. When the lens barrier 38 is placed in the close position, a motor 100 for a lens mirror shell is activated again, thereby the lens mirror shell 42 placed at a shell bottom position is moved forward the side of a lens aperture section formed on the external case. Then, the lens mirror shell 42 comes in contact with the arm 150 and pushes up the lens barrier 38 through the arm 150 in the direction against the force of the compression spring 168.  The lens barrier 38 is moved into the lens aperture section, and then the lens barrier 38 can form an identical plane with the external case, thereby no step appears between the lens barrier 38 and the external case, and neither dirt nor dust accumulates there.
