Title: Control device for engine
Inventor: HAYAMIZU TOSHIBUMI
IPC: F02D45/00
Filed: 2008-05-26
Abstract: <P>PROBLEM TO BE SOLVED: To prevent ignition control and/or fuel injection control from being performed based on a wrong cylinder discrimination result caused by the reverse rotation of an engine.  <P>SOLUTION: An air flow meter 14 includes a bypass structure for easily taking in a backward flow of intake air, and a high response/high-speed starting sensor element 5 in order to detect an intake air amount for a forward flow and the backward flow separately. When the engine 11 is reversed, the flow of the intake air in an intake pipe 12 is reversed, that is, the intake air flows backward. When engine speed falls in a low rotation speed region below a prescribed threshold set lower than targeted idle rotating speed (the low rotation speed region in which the engine 11 may be reversed), and when the air flow meter 14 detects the backward flow of the intake air, cylinder discrimination based on an engine rotation signal from a crank angle sensor 28 (a cam angle sensor) is prohibited (or disabled) until the engine 11 is completely stopped.  <P>COPYRIGHT: (C)2010,JPO&INPIT

Abstract: <P>PROBLEM TO BE SOLVED: To provide a driving control device can avert the step-out of stepping motor during spherical aberration correction at a low cost with a small size, a drive control method, and to provide an optical pickup system.  <P>SOLUTION: A control section 22 drives a collimator lens 12 from an origin position with driving pulses of a prescribed pulse rate T1, by as much as a prescribed number A of clocks thereby moving the collimator lens 12. The control section returns the collimator lens 12 to the origin position with the pulse rate T2 higher than the pulse rate T1, and counts the number B of clocks of the driving pulses required for returning. The control section 22 repeats counting, by increasing the pulse rate T2 by one step each until the number A of clocks becomes equal to the number B of clocks. The control section 22 makes the determination that there is the step-out when the number A is not equal to number B, and determines the pulse rate T2 lowered by one step from the pulse rate T2 determined as having the existence of the step-out, as the pulse rate of the spherical aberration correction operation.  <P>COPYRIGHT: (C)2010,JPO&INPIT
