    • An automatic vending machine has a plurality of commodity storage chambers in a side-by-side arrangement that are divided from one another by thermally-insulating vertical dividers so that each chamber can be heated or refrigerated individually. Each chamber has a plurality of vertically spaced commodity shelves and an elevator bucket that is adapted to receive a commodity from a selected shelf. All of the elevator buckets are rigidly connected by laterally extending connecting members that are disposed through respective vertically extending slots in the dividers, so that a single unit of plural elevator buckets acts to fetch a selected commodity, heated or cooled. A pair of flexible heat-shielding sealing strips are securely fitted in each of the slots in a manner that each of the connecting members slides on and between the corresponding pair of the sealing strips to prevent communication between the adjacent chambers as the connecting member moves vertically.
    • 自动售货机具有并排布置的多个商品储存室,它们通过隔热垂直分隔器彼此分隔开,使得每个室可以单独加热或冷藏。 每个室具有多个垂直间隔的商品货架和适于从所选货架接收商品的电梯桶。 所有的电梯铲斗通过侧向延伸的连接构件刚性地连接,该连接构件通过分隔件中的相应的垂直延伸的狭槽设置,使得多个电梯桶的单个单元用于取出选定的商品,加热或冷却。 一对柔性隔热密封条以每个连接构件在相应的一对密封条之间和之间滑动的方式牢固地装配在每个槽中,以防止连接构件垂直移动时相邻室之间的连通 。

    • In a memory controller system, a method for granting a system memory by a memory request arbitrator to a request among a plurality of pending memory access requests is provided. The plurality of the memory access requests includes Rfrsh_Hreq, Crt_Hreq, Group AB, Crt_Lreq and Rfrsh_Lreq and are respectively asserted by a host control circuitry and/or a graphical control circuitry which are implemented and integrated on a single monolithic semiconductor chip. The host control circuitry and the graphical control circuitry shares the system memory and the memory request arbitrator includes a refresh queue and the graphics control circuitry includes a CRT FIFO. The method prioritizes the plurality of the memory access requests in order of Rfrsh_Hreq>Crt_Hreq>Group AB>Crt_Lreq>Rfrsh_Lreq. The Rfsh_Hreq is memory refresh request signal of first type whenever the refresh queue being full, the Crt_Hreq is memory access signal of a first type for fueling the CRT FIFO with display data, the Group AB are memory access request signals of a second type output either from the graphical control circuitry or the host control circuitry, the Crt_Lreq is memory access signal of a third type for fueling the CRT FIFO with display data, the Rfrsh_Lreq is memory refresh request signal of second type whenever the refresh queue being non-empty.
    • 在存储器控制器系统中,提供了一种通过存储器请求仲裁器将系统存储器授予多个未决存储器访问请求中的请求的方法。 多个存储器访问请求包括Rfrsh_Hreq,Crt_Hreq,组AB,Crt_Lreq和Rfrsh_Lreq,并且分别由实现并集成在单个单片半导体芯片上的主机控制电路和/或图形控制电路断言。 主机控制电路和图形控制电路共享系统存储器,并且存储器请求仲裁器包括刷新队列,并且图形控制电路包括CRT FIFO。 该方法按照Rfrsh_Hreq> Crt_Hreq> Group AB> Crt_Lreq> Rfrsh_Lreq的顺序对多个存储器访问请求进行优先级排序。 Rfsh_Hreq是刷新队列满时的第一种类型的存储器刷新请求信号,Crt_Hreq是用于向显示数据供给CRT FIFO的第一种存储器访问信号,组AB是第二类型输出的存储器访问请求信号 从图形控制电路或主机控制电路,Crt_Lreq是用于向CRT FIFO加载显示数据的第三种存储器访问信号,每当刷新队列不为空时,Rfrsh_Lreq是第二类型的存储器刷新请求信号。
