Filed: 1999-09-08
Abstract: PROBLEM TO BE SOLVED: To prevent worsening of exhaust property during control of the number of idle revolutions of an engine. SOLUTION: An electronic control unit(ECU) 10 effects control of an intake air amount and the number of revolutions through which feedback control of an engine intake air amount is effected according to the number of revolutions, and stops control of an intake air amount and the number of revolutions when the number of revolutions is reduced due to worsening of combustion, and performs control of an ignition timing and then umber of revolutions through which feedback control of an ignition timing is effected according the number of revolutions.  Further, the ECU 10 stops control of the ignition timing and the number of revolutions by deciding that an engine combustion state is improved when a state that an ignition timing feedback correction amount is reduced to a given value is continued for a specified period during execution of control of an ignition timing and the number of revolutions, and is returned to control of an intake amount and the number of revolutions. This constitution suppresses a delay in warming up of an exhaust gas purifying catalyst to a minimum limit by executing control of an ignition timing and the number of revolutions and prevents worsening of an exhaust gas property.

Abstract: PROBLEM TO BE SOLVED: To detect a surface defect of even a cast product of a complicated shape, by emitting to a surface to be inspected lights with different angles from a plurality of directions to the circumferential direction of a photodetecting axis of an image pick-up camera. SOLUTION: A cast product 1 is illuminated by illuminating devices 3a, 3b and an inspection face of the product 1 is photographed by an image pick-up camera 2. The illuminating devices 3a, 3b are circular fluorescent lamps, with angles of incidence 30 deg., 90 deg. to a photographed image 2A. The illuminating devices are driven by 8 and controlled by 10, so that the illuminating devices can be turned on simultaneously or individually.
