摘要： The basic fuel injection time duration or the basic injector opening time is computed on the basis of an intake pressure and an engine speed. A start temperature correction value is selected on the basis of the engine temperature at the time of or immediately after the start up of the engine and attenuated in accordance with the time elapsed after the start up of the engine, such that, the lower the engine temperature is at the time of start up, the greater the start temperature correction value is. The rate of fuel injection rate is controlled by correcting the basic fuel injection time on the basis of the start temperature correction value and a condition of the engine.

摘要： The amount of engine acceleration is detected as the amount of change in the absolute pressure in the intake passage, and an asynchronous fuel injection is conducted regardless of the crank position as the amount of acceleration exceeds a predetermined reference value. In ordinary state of engine operation, the synchronous fuel injection is conducted in synchronism with the crank rotation such that the air-fuel ratio of the mixture coincides with the stoichiometric one, upon sensing the air-fuel ratio from the content of oxygen remaining in the exhaust gas. The mixture is made richer or leaner than the stoichiometric one in accordance with the state of operation of the engine. The judging level for the judgement as to whether the asynchronous fuel injection is necessary or not is increased or decreased in accordance with the air-fuel ratio so that the asynchronous fuel injection is conducted taking into account also the air-fuel ratio.

摘要： Disclosed is a method of controlling the air-fuel ratio of an air-fuel mixture to be supplied to an internal combustion engine. The method employs a feedback control in which the control is made to maintain the air-fuel ratio at the stoichiometric level in accordance with the air-fuel ratio read through the detection of a component of the exhaust gas and, at least during the idling of the engine after the warming up of the same, a lean control in which the control is made to maintain the air-fuel ratio at the leaner side of the stoichiometric level. The lean control is allowed when the mean value of the engine speed over a predetermined period is greater than a predetermined reference value during the idling after warming up of the engine, while the feedback control is conducted when the mean value is below the predetermined reference value. Disclosed also is an apparatus suitable for carrying out this method.

摘要： Disclosed is a method of controlling the air-fuel ratio of an air-fuel mixture to be supplied to an internal combustion engine by the selective use of either one of a feedback control mode in which the control is made to maintain the air-fuel ratio at the stoichiometric level and a lean control mode in which the control is made to maintain at the leaner side of the stoichiometric level in accordance with the state of operation of the engine. In this method, the execution of the control in the lean control mode is prohibited for a predetermined period of time during acceleration of the engine at least when the speed of vehicle mounting the engine is below a predetermined speed, and the air-fuel ratio control is made in the feedback control mode in the period of time. Consequently, the period of engine operation in the lean control mode is maximized without impairing the driveability of the engine particularly when the engine is accelerated from low speed. Disclosed also is an apparatus suitable for carrying out this method.

摘要： An eyeglass lens grinding apparatus for grinding a periphery of a lens. A processing device has abrasive wheels, and processes the lens while depressing the lens onto at least one of the abrasive wheels rotatingly driven by an abrasive wheel rotating motor. The lens is fixedly mounted to a first lens chuck shaft through a lens fixing cup. A second lens chuck shaft has a lens pressing holder, and is arranged coaxially with respect to the first lens chuck shaft. A rotating device has a motor and a transmission member that transmits rotational force of the motor to the first lens chuck shaft. A chucking device clamps the lens by relatively moving the second lens chuck shaft with respect to the first lens chuck shaft in a direction of an axis of rotation with a moving mechanism. A first detector detects an angle of rotation of the second lens chuck shaft when the second lens chuck shaft is rotatingly driven by the first lens chuck shaft rotated by the rotating device in a state where the lens is clamped by the first and second lens chuck shafts. A controller controls processing based on a result of detection by the first detector.

摘要： An eyeglass lens is designed to permit the operator to preset by himself the conditions for bevel formation in AUTO mode so that he can perform efficient lens processing. The eyeglass lens grinding apparatus includes frame data inputting section for entering configuration data on an eyeglass frame, layout data inputting section for entering layout data to be used in providing a layout of an eyeglass lens to be processed which corresponds to the eyeglass frame, edge position detecting section for determining data on the edge position of the processed lens on the basis of the frame configuration data and the layout data. The lens grinding apparatus further includes an arithmetic control circuit, a parameter input section, and a sequence program stored in a main program memory. The sequence program allows a user to input or alter the parameters—even when the lens grinding apparatus operates in an auto-processing mode—used to calculate bevel processing data. Allowing a user to input or alter parameters, even in an auto-processing mode, enhances the utility of the lens grinding apparatus. Further, even after the bevel processing data has been calculated on the basis of a user input or altered parameter, the user can, in a forced-processing mode, further alter a portion of the bevel processing data calculated using an altered parameter in the auto-processing mode.
