    • A power tool with first and second housing portions, a powertrain, a mounting hub and a lock bar. The powertrain has an output member that extends from the second housing portion and which is movable relative to an output member axis. The mounting hub is fixedly coupled to one of the first and second housing portions. The lock bar is movably mounted to the other one of the first and second housing portions between a locked position and a first unlocked position. The lock bar cooperates with the mounting hub in the locked position to inhibit relative rotation between the first and second housing portions. Placement of the lock bar in the first unlocked position permits relative rotation between the first and second housing portions.
    • 具有第一和第二壳体部分的动力工具,动力系,安装轮毂和锁杆。 动力系具有从第二壳体部分延伸并且可相对于输出构件轴线移动的输出构件。 安装毂固定地联接到第一和第二壳体部分中的一个。 锁定杆在锁定位置和第一解锁位置之间可移动地安装到第一和第二壳体部分中的另一个。 锁定杆在锁定位置与安装毂配合以阻止第一和第二壳体部分之间的相对旋转。 锁定杆在第一解锁位置的放置允许第一和第二壳体部分之间的相对旋转。

    • Two design variations which allow multiple processors to start up using a single ROM are disclosed. In each design, a single, primary processor is allowed to perform a complete POST while the remaining, secondary processors are directed in the course of their POST to perform a more limited initialization sequence. At power on, the primary processor begins a normal POST, while the secondary processors are held until a vector is placed into a redirection vector location. Each secondary processor is then subsequently started, using its own initialization code located at the address indicated by the redirection vector. The first technique is applicable to general multiprocessor systems because the implementation of this design can be run either from external software or from an addition to the operating system of the particular machine on which it is being used. The second technique is more specifically oriented to a particular system, and includes the use of an identity register to differentiate between primary and secondary processors.
    • 公开了允许使用单个ROM启动多个处理器的两种设计变型。 在每个设计中,允许单个主处理器执行完整的POST,而剩余的辅助处理器在其POST过程中被引导以执行更有限的初始化序列。 上电时,主处理器开始正常POST,而辅助处理器保持,直到向量放置到重定向向量位置。 然后,使用其位于由重定向向量指示的地址处的自己的初始化代码随后启动每个二级处理器。 第一种技术适用于一般的多处理器系统,因为这种设计的实现可以从外部软件运行,也可以从添加到正在使用它的特定机器的操作系统运行。 第二种技术更具体地针对特定系统,并且包括使用身份寄存器来区分主处理器和辅助处理器。
