    • An air-fuel ratio control apparatus is applied to an internal combustion engine including a variable lift mechanism which changes a lift amount of an intake valve. An oxygen sensor, which outputs a signal indicating an oxygen concentration in exhaust gas, is provided downstream of an exhaust gas purification catalyst in an exhaust passage of the internal combustion engine. Air-fuel ratio control is performed to correct the fuel injection amount command value using the correction amount that is set based on the value output from the oxygen sensor. The relationship among the deviation of the correction amount from its reference value, the learned small lift value, the learned medium lift value, and the lift amount is learned. The learned deviation value is calculated based on the lift amount, using the learned relationship. Then, the fuel injection amount command value is corrected by the correction amount including the calculated learned deviation value.

    • A grinding machine is provided with first and second grinding wheels selectively used in dependence on the steps of machining operations. The second grinding wheel is grooved so that at least one oblique groove vertically crosses a contact surface on which a grinding surface of the second grinding wheel contacts with a workpiece, and thus, is capable of releasing a dynamic pressure in coolant generated between the grinding surface and the workpiece since coolant supplied from over the contact surface flows out from both of the upper and lower sides of the contact surface through the at least one oblique groove. Since it does not occur that fluctuations in the dynamic pressure generated in coolant cause the distance between the second grinding wheel and the workpiece to be varied, the accuracy in grinding the workpiece with the second grinding wheel can be enhanced.
    • 磨床设置有根据加工操作的步骤选择性地使用的第一和第二砂轮。 第二砂轮是开槽的,使得至少一个斜槽垂直地穿过第二砂轮的研磨表面与工件接触的接触表面,因此能够释放在研磨表面之间产生的冷却剂中的动态压力 并且由于从接触表面上方供给的冷却剂通过至少一个倾斜槽从接触表面的上侧和下侧流出,所以工件。 由于不会发生冷却剂中产生的动态压力的波动导致第二砂轮和工件之间的距离变化,所以可以提高用第二砂轮研磨工件的精度。
