    • An arbiter circuit includes a priority coefficient calculating unit, a priority coefficient comparator an acceptance determining unit, and a priority determining unit. The priority coefficient calculating unit calculates for each request an arbitration priority coefficient based on a priority level set for each request by requesters. The priority coefficient comparator compares arbitration priority coefficients calculated for the requesters by the priority coefficient calculating unit. The acceptance determining unit determines whether to accept the requests based on the comparison result by the priority coefficient comparator. When the arbitration priority coefficient calculated by the priority coefficient calculating unit is equal between two or more requests, the priority determining unit determines a priority order for accepting the requests.
    • 仲裁器电路包括优先级系数计算单元,优先级系数比较器,接受确定单元和优先级确定单元。 优先级系数计算单元基于为请求者针对每个请求设置的优先级来为每个请求计算仲裁优先级系数。 优先级系数比较器比较由优先级系数计算单元计算的请求者的仲裁优先级系数。 接受确定单元基于优先级系数比较器的比较结果确定是否接受请求。 当由优先级系数计算单元计算的仲裁优先级系数在两个或更多个请求之间相等时,优先级确定单元确定接受请求的优先顺序。

    • A needle threading device of a sewing machine comprising a needle threading shaft mounted rotatably and vertically movably; a needle threading hook fixed to a lower end of the needle threading shaft; and a rotating mechanism that rotates the needle threading shaft such that the needle threading hook passes through a needle eye of the sewing needle. In a such a needle threading device, a first thread guide member is fixed to a lower end of the needle threading shaft and arranged opposed to the needle threading book with respect to the needle threading shaft; a second thread guide member is pivotally mounted on the lower end of the needle threading shaft and linked to the first thread guide member via a link mechanism. The second thread guide member is mounted with a thread retaining unit that retains the upper thread upon needle hooking.
    • 1.一种缝纫机的针刺装置,其特征在于,包括可旋转地且可垂直移动地安装的针穿线轴; 固定在针穿轴的下端的针刺钩; 以及旋转机构,其使针穿轴旋转,使得针刺钩穿过缝纫针的针眼。 在这种针刺装置中,第一线引导构件被固定到针穿轴的下端,并且相对于针穿线与针穿线对置设置; 第二线引导构件枢转地安装在针穿轴的下端,并且经由连杆机构与第一线引导构件连接。 第二线引导构件安装有将针脚保持在针钩上的线保持单元。
