    • When a signal is read from a CCD solid-state image pickup element, the CCD solid-state image pickup element is driven with at least two driving voltages so that high-speed reading is performed with generation of noise due to interference between the driving voltages reduced. The CCD solid-state image includes a charge storage section between a vertical transfer register and a horizontal transfer register. By performing the transfer of charge in the direction of columns during an effective transfer period of the transfer in the direction of rows, signal charge of one row generated by a light receiving sensor is transferred to the charge storage section, and by performing the transfer outside the effective transfer period in the transfer in the direction of the row, the signal charge of one row transferred to the charge storage section is transferred to the horizontal transfer register.

    • A plunger slidable in a barrel of a plunger pump is actuated by an engine driven camshaft to feed high pressure fuel through a delivery valve to an injection nozzle. A needle type valve element extends through a nozzle chamber in the nozzle connected to the pump to control fuel flow from the nozzle chamber through an injection orifice into the engine. The needle end of the valve element is exposed to pressurized fuel in the nozzle chamber, and a spring applies a force to the other end of the valve element to urge the valve element to block the injection orifice. As the pump plunger moves through its injection stroke, the pressure in the nozzle chamber increases and overcomes the force of the spring to move the valve element to unblock the orifice to initiate fuel injection. Near the end of the plunger stroke, the plunger uncovers a hole in the barrel so that pressurized fuel is fed through passageways in the plunger, the hole and a check valve to a surface of the valve element to apply a force to the valve element in the same direction as the spring force to move the valve element to block the orifice and terminate fuel injection without valve element rebound or fuel dribbling.
    • 在柱塞泵的筒体中可滑动的柱塞由发动机驱动的凸轮轴致动,以通过输送阀将高压燃料供给到喷嘴。 针型阀元件延伸穿过连接到泵的喷嘴中的喷嘴室,以控制从喷嘴室通过喷射孔流入发动机的燃料流。 阀元件的针端暴露于喷嘴室中的加压燃料,弹簧向阀元件的另一端施加力以促使阀元件阻塞喷射孔。 当泵柱塞移动通过其喷射行程时,喷嘴室中的压力增加并且克服弹簧的力以移动阀元件以解除阻塞孔以启动燃料喷射。 在柱塞行程末端附近,柱塞露出筒体中的孔,使得加压燃料通过柱塞的通道,孔和止回阀进入阀元件的表面,以向阀元件施加力 与弹簧力相同的方向来移动阀元件以阻塞孔口并终止燃料喷射而没有阀元件反弹或燃料循环。

    • There is a need for improving the accuracy of estimating a gain error for an angular velocity sensor. An error estimation section and a correction section are provided as well as a gyroscope that detects an angular velocity of a vehicle. The error estimation section assumes the gain error of the gyroscope to be a state quantity and finds an estimated value for the gain error using a Kalman filter. Based on the gain error found by the error estimation section, the correction section corrects a gain correction amount used for gain correction of values detected by the gyroscope. The correction section corrects the gain correction amount dedicated to right turn based on the gain error found by the error estimation section when the vehicle is assumed to turn right. The correction section corrects the gain correction amount dedicated to left turn based on the gain error found by the error estimation section when the vehicle is assumed to turn left.
    • 需要提高角速度传感器的增益误差的估计精度。 提供了误差估计部和校正部,以及检测车辆的角速度的陀螺仪。 误差估计部分将陀螺仪的增益误差作为状态量,并使用卡尔曼滤波器求出增益误差的估计值。 基于由误差估计部分发现的增益误差,校正部分校正用于陀螺仪检测到的值的增益校正的增益校正量。 当车辆被判定为右转时,校正部分基于由误差估计部分发现的增益误差来校正专用于右转的增益校正量。 基于当车辆左转时由误差估计部发现的增益误差,校正部分校正专用于左转的增益校正量。
