    • An air-fuel ratio control system for an internal combustion engine having a two-barrel carburetor comprising a primary side having a main metering system and a slow speed system and a secondary side having a main metering system. Two on-off electro-magnetic valves are provided for correcting the air to be supplied to air bleeds of both the primary and secondary sides for correcting air-fuel ratio of the air-fuel mixture supplied by the carburetor.A first passage is provided for connecting the slow speed system of the primary side to one of the electromagnetic valves, a second passage is adapted to connect the main metering system of the secondary side to the one of the electromagnetic valves; and a third passage is provided connecting the main metering system of the primary side to the other electromagnetic valve.A change-over valve is provided for changing the connection between the electromagnetic valve and first and second passages. The change-over valve is so arranged to normally communicate the electromagnetic valve with the first passage and to communicate the electromagnetic valve to the second passage when the secondary side becomes to operate upon heavy load.
    • 一种用于具有双桶化油器的内燃机的空燃比控制系统,其包括具有主计量系统和慢速系统的初级侧和具有主计量系统的次级侧。 提供两个开关电磁阀,用于校正供给到一次侧和二次侧的空气出口的空气,用于校正由化油器供应的空气燃料混合物的空燃比。 第一通道用于将初级侧的慢速系统连接到电磁阀之一,第二通道适于将次级侧的主计量系统连接到电磁阀之一; 并且提供将第一侧的主计量系统连接到另一电磁阀的第三通道。 提供转换阀,用于改变电磁阀和第一和第二通道之间的连接。 转换阀被布置成使电磁阀与第一通道正常连通,并且当次级侧在重负载下操作时,将电磁阀连通到第二通道。

    • A rechargeable battery pack attachable to a power tool includes a display element, a remaining capacity detection device, a remaining capacity display control device, an abnormality detection device, and an abnormality display control device. The display element is provided such that a lighted state thereof can be confirmed from outside. The remaining capacity detection device detects a remaining capacity of a rechargeable battery. The remaining capacity display control device displays the remaining capacity detected by the remaining capacity detection device by controlling the lighted state of the display element. The abnormality detection device detects an abnormality of the rechargeable battery. The abnormality display control device displays the abnormality of the rechargeable battery detected by the abnormality detection device by controlling the lighted state of the display element to an abnormality display state, which is different from a remaining capacity display state controlled by the remaining capacity display control device.
    • 可附接到电动工具的可充电电池组包括显示元件,剩余容量检测装置,剩余容量显示控制装置,异常检测装置和异常显示控制装置。 显示元件设置成能够从外部确认其点亮状态。 剩余容量检测装置检测可再充电电池的剩余容量。 剩余容量显示控制装置通过控制显示元件的点亮状态来显示剩余容量检测装置检测到的剩余容量。 异常检测装置检测可再充电电池的异常。 异常显示控制装置通过将显示元件的点亮状态控制为与由剩余容量显示控制装置控制的剩余容量显示状态不同的异常显示状态来显示由异常检测装置检测到的可再充电电池的异常 。
