  • Patent number: 8965663
    Abstract: A fuel injection control apparatus includes a first injection timing setting device, a target second injection timing setting device, a reference injection timing calculator, and a second injection timing setting device. The reference injection timing calculator is configured to calculate, as a reference injection timing, a timing at which a second-injection boosting operation is to be completed. The second-injection boosting operation is to re-boost a reduced voltage which has been reduced because of an execution of a first injection operation by using a booster circuit. The second injection timing setting device is configured to set, as a second injection timing at which a second injection operation is to be started, a later one of a target second injection timing set by the target second injection timing setting device and the reference injection timing calculated by the reference injection timing calculator.

  • Patent number: 8712743
    Abstract: To provide an intake parameter-calculating device and intake parameter-calculating method for an internal combustion engine, which are capable of accurately calculating intake parameters in a case where an intake throttle valve is provided. The intake parameter-calculating device 1 includes an ECU 2. The ECU 2 calculates an error KTHERRCOR using an error model equation (8) (step 2), and calculates a correction coefficient KTHCOR as the reciprocal of the sum of the error KTHERRCOR and 1 (step 3). The ECU 2 calculates a passing air amount GAIRTH by correcting a basic passing air amount GAIRTHN calculated by an equation (11) using a correction coefficient KTHCOR (step 6). A model parameter A for the error model equation (8) is calculated using equations (14) to (18) by onboard identifying calculation with uniform weighting (steps 48 to 53).

  • Patent number: 8029335
    Abstract: In a wafer processing method, rough grinding using a first grinding stone is divided into first and second steps. In the first step, a wafer is processed into a concave shape at a first transfer rate with a reinforcing rib area slightly left. Thereafter, as primary rough grinding in the second step, the grinding stone is positioned slightly on the inner circumferential side and the wafer is further processed into the concave portion at a second transfer rate faster than the first transfer rate. Since the first transfer rate is suppressed to a rate not to cause a burst chipping, a burst chipping resulting from the second step fast in the processing rate to ensure productivity will occur at the stepped edge portion on the inside of the reinforcing rib area surface. Thus, the flatness of the reinforcing rib area can be ensured.

  • Patent number: 6983735
    Abstract: A control for controlling an intake air into an engine is provided. A control valve for adjusting an amount of the intake air into the engine is provided. A desired opening degree of a control valve provided in an intake air passage into the engine is determined based on a clogging coefficient. The clogging coefficient indicates a degree of clogging of the intake air passage. An opening degree of the control valve is controlled to converge to the desired opening degree. The clogging coefficient is updated based on a feedback correction amount for feedback controlling a rotational speed of the engine during idling operation. If a leakage in a blow-by gas passage that is connected between the engine and the intake air passage is detected, the update of the clogging coefficient is prohibited.
