Title: Control device for cylinder injection type internal combustion engine
Inventor: OTANI GENKI
IPC: F02D41/06
Filed: 2001-07-25
Abstract: PROBLEM TO BE SOLVED: To provide a control device for a cylinder injection type internal combustion engine, capable of suppressing starting failures at restart or the like. SOLUTION: The valve timing of an intake valve 20 in an engine 1 is made variable, by hydraulically controlling a valve-timing variable mechanism 25. When it is judged that the valve timing variable mechanism 25 does not return to the position of locating the valve timing of intake valve 20 as a most delay angle (reference position) at start of the engine 1, the fuel injection amount during engine start and immediately after finishing the engine start, is corrected to be reduced. Thereby, even if the valve timing variable mechanism 25 does not return to the reference position and an internal EGR amount is excessive by the fuel combustion in such a state as to cause an insufficient oxygen condition, it can be suppressed that an air/fuel ratio becomes excessively rich due to such a situation.

Abstract: PROBLEM TO BE SOLVED: To realize an YC separation processing whose circuit scale is suppressed by using clock frequencies having different frequency dividing ratios from each other, in the constitution for intending the improvement of a horizontal resolution and the suppression of a residual chromatic signal in an YC separation apparatus. SOLUTION: A clock phase-synchronized with a video signal is so created by a clock generating circuit 2 and by a color demodulating circuit 5 as to sample the video signal by an A/D converter 1. After subjecting the video signal to a clock-rate conversion by a second thinning circuit 3, a chromatic signal is extracted from the converted video signal by a complex filter 4. Then, after demodulating the chromatic signal to a color-difference signal by an interpolating circuit 6 based on a timing signal sent from the color demodulating circuit 5, the color-difference signal is interpolated by a predetermined clock. Further, the interpolated color-difference signal is modulated again to the chromatic signal by a modulating circuit 7.  Also, after subjecting the video signal sampled by the A/D converter 1 to a predetermined clock conversion by a first thinning-off circuit 8, the converted video signal is subjected to a delaying adjustment by a delaying circuit 9. Then, the chromatic signal is so subtracted from the delayed video signal by a subtracting circuit 10 as to create a luminance signal.

Abstract: PROBLEM TO BE SOLVED: To suppress uneven wear of a brush and lowering of performance of a DC motor. SOLUTION: A support piece 17C to support a spiral spring is integrally situated at a brush holder 17. The support piece 17C is situated upright at the side of a body part 17A and has a protrusion part 17a formed by striking on a surface in a surface in the direction of a plate thickness. The protrusion part 17a is formed in an inclining state so that height protruding from the surface of the support piece 17C is gradually increased from the upper side toward the lower side in the vertical direction of the support piece 17C. In the spiral spring, its own inner peripheral end part is supported by the support piece 17C of the brush holder 17, and movement in a direction, in which it is pulled out from the support piece 17C, is regulated by the protrusion part 17a formed on the support piece 17C.
