    • The number of steps required for a step motor to reach a target load is computed by dividing in proportion the number of steps required for the step motor to move a fuel metering member to move from an idle position to a full-load position by a ratio between a target load value of an electric command given by fuel supply command means such as an accelerator pedal to an internal combustion engine and a maximum value of the electric command. The step motor is driven by the computed step number to correct variations in the characteristics of the fuel supply command means. The number of load estimation steps for the step motor driven by drive means is determined by dividing in proportion an electric maximum command given from the fuel supply control means by a ratio between the actual amount of rotation of the step motor and the amount of rotation from the idle position to the full-load position, and a step-out condition of the step motor is detected from the estimation step number.
    • 步进电动机达到目标负载所需的步骤数是通过将步进电机所需的步数按比例分配来计量的,以使燃料计量构件从空转位置移动到满载位置乘以一个比例 在由诸如加速踏板的燃料供给命令装置给予内燃机的电命令的目标负载值和电命令的最大值之间。 步进电机由计算出的步数驱动,以校正燃料供给指令装置的特性的变化。 由驱动装置驱动的步进电机的负载估计步骤的数量通过将从燃料供给控制装置给出的电最大指令的比例除以步进电动机的实际旋转量与旋转量之间的比例来确定 从估计步骤号检测到满载位置的空转位置和步进电机的退出状态。

    • A door opening/closing mechanism fitted on a door that closes and opens an opening formed in the body of an apparatus by being brought into and out of contact with the rim of the opening has cam mechanisms that permit the door to engage with and disengage from the body at either of the right and left sides of the door. The cam mechanisms can be brought into a first lock position in which they lie symmetrically at both sides of the door and into a second lock position in which they lie symmetrically at both sides of the door, and each have a hinge pin that serves as a rotation axis in the second lock position and a groove cam that engages with the hinge pin in such a way as to be movable relative to the hinge pin. The groove cam has a slide portion on which a part of the innermost portion of the hinge pin slides when the cam mechanism is moved from the first lock position to the second lock position and of which the length in the direction of the width of the door is greater than the maximum permissible variation in the outermost distance (L) between the two groove cams formed at both sides of the door. When the door is closed, the cam mechanisms at both sides are kept in the first lock position and, when the door is opened at one side, the door slides and thereby causes the cam mechanism at the other side to be brought into the second lock position so as to be rotatably locked in the second lock position.
