    摘要: The present invention provides an object lens actuator in which a tilt of an object lens due to a change of an ambient temperature is inhibited even when a metal member is attached to a resin based securing part. It is desirable to improve quality of writing and playing in a disc drive using the object lens actuator. This is achieved by coupling a metal member having a flat portion and bent portions to a securing part near top ends of the bent portions. The flat portion has a normal in the focusing direction. The bent portions extend in the focusing direction from the respective ends of the flat portion in the tracking direction. The securing part has an opening therethrough in the focusing direction, and in the opening, the metal member and the securing part may be coupled between each outermost two support members in the focusing direction.

    摘要: An optical disk apparatus includes an objective-lens for converging light on a recording surface of an optical disk, and an objective-lens driving device for driving the objective-lens in a focusing direction and a tracking direction. The objective-lens driving device includes a focusing coil having four edges to enclose the objective-lens, and two pairs of permanent magnets. The two pairs of permanent magnets are arranged so that polarities thereof become identical to sides of focusing coil, wherein one pair of the permanent magnets is arranged opposed to an edge of the focusing coil, and an other pair of the permanent magnets is arranged opposed to an edge opposite to the edge of the focusing coil. An interval between two magnets constituting the one pair of permanent magnets is narrower than an interval between two magnets constituting the other pair of permanent magnets.

    摘要: The valve opening of an exhaust gas recirculating valve is controlled in response to operating conditions of the engine so as to regulate the amount of exhaust gas recirculation to values appropriate to the operating conditions of the engine. The valve opening of the exhaust gas recirculating valve is varied by a predetermined value when the engine is determined to be in a predetermined accelerating condition or a predetermined decelerating condition. Further, the predetermined value is corrected in accordance with the detected shift lever position. Preferably, the valve opening of the exhaust gas recirculating valve is increased or decreased by a predetermined incremental value or a predetermined decremental value when the engine is in the predetermined accelerating condition or the predetermined decelerating condition, and the predetermined incremental value or the predetermined decremental value is corrected in accordance with the detected position of the shift lever.

    摘要: An air intake side secondary air supply system for an internal combustion engine including an open/close valve disposed in an air intake side secondary air supply passage and an oxygen concentration sensor producing an output signal whose level is substantially proportional to an oxygen concentration of the exhaust gas, executes a duty ratio control of the open/close valve for a feedback control of the air fuel ratio of mixture to be supplied to the engine. When the air/fuel ratio has changed from rich to lean with respect to a target air/fuel ratio, a correction value for reducing the valve open period during the air/fuel ratio is detected to be lean, is increased. On the other hand, when the air/fuel ratio has changed from lean to rich with respect to the target air/fuel ratio, a correction value for increasing the valve open period during the air/fuel ratio is detected to be rich, is increased.
