摘要:
An operating environment of a measurement apparatus for measuring semiconductor devices under test. In particular, a measurement apparatus for a device under test and a method using the measurement apparatus in which a user can promptly and easily understand the selection of the semiconductor measurement-evaluation application used for measuring the device under test, the setting of parameters used during execution, the display of the execution and the result of the execution, and the programming-related operations.
摘要:
A semiconductor testing system comprising an input; a display; multiple testing units; a memory in which is stored multiple applications that specify the operating procedure of the testing units and multiple categories that are related to the applications; and a controller that has the function of displaying the categories, displaying on the display the applications relating to the categories selected based on the input from the input, and conducting the applications that have been selected by the input from among the displayed applications and controlling the testing units, and the like.

An engine controller controls an injection quantity or intake airflow supplied to a cylinder of an engine. Constant associated with e running resistance of the vehicle are reconfigured according to vehicle specifications when a change is made to the vehicle specifications. A target acceleration is determined from the accelerator operation amount. An acceleration resistance is determined using the target acceleration and a constant based on the vehicle weight. At least an air resistance and a rolling resistance are added to the acceleration resistance to determine a running resistance for accelerating or decelerating the vehicle at the target acceleration. A driving wheel torque is determined using the running resistance and a constant based on the effective tire radius. An engine output shaft torque equivalent to a driver-requested torque is determined using the driving wheel torque and a constant based on the final gear ratio.
摘要:
During a short duration injection, a triangular geometry is drawn in terms of the injection rate with respect to time, while a trapezoidal geometry is drawn during a long duration injection. The ON timing of the drive pulse is determined to be at a valve opening pressure achieving time before the start point of formation in time of the geometry. An injection pulse duration is determined from “the valve opening pressure achieving time+a needle rise time—a valve closing pressure achieving time,” and then the OFF timing of the drive pulse is determined.
