    • Disclosed is a chain-type conveyor having a direction-changing roller capable of easily changing the orientation of an article to continuously transfer the article, without using any separate direction-changing unit at a corner part of the conveyor, in the case in which the transfer direction of the article has to be changed during the transfer of the article by a conveyor, thereby reducing a cost of the article and usefully utilizing a limited space. The chain-type conveyor for transferring an article in a straight direction when the chain-type conveyor is driven by driving means includes a plurality of chain plates foldably connected to each other, a pair of brackets each having a lower portion symmetrically fixed to an outer surface of the chain plate in a front/rear direction and an inclined upper portion, and direction-changing rollers rotatably coupled to the brackets in a diagonal direction and changing a transfer direction of the article, which is transferred along a roller-type conveyor and then stopped by a stopper roller rotatably installed to a front portion of the chain-type conveyor, by a rotational force generated by friction between the article and the direction-changing roller.
    • 公开了一种链式输送机,其具有能够容易地改变制品的定向以便连续地转移物品的方向转换辊,而不需要在输送机的拐角部分处使用任何单独的方向改变单元,其中, 在通过输送机传送物品期间必须改变物品的传送方向,从而降低物品的成本并有效地利用有限的空间。 当链式输送机由驱动装置驱动时,用于在直线方向上传送物品的链式输送机包括可折叠地连接的多个链板,一对托架,每个托架具有对称地固定到外部的下部 链条板的前后方向的表面和倾斜的上部,以及沿对角线方向可旋转地联接到托架的方向改变辊,并且改变沿着辊式输送机传送的物品的传送方向,以及 然后由可旋转地安装在链式输送机的前部的止动辊通过由制品和方向转换辊之间的摩擦产生的旋转力而停止。

    • A method and an apparatus for restoring defective memory cells are provided. The apparatus includes memory, a memory scan controller, which scans the memory to see if the memory is defective when a system starts operating and transmits resulting defect information to a memory controller, and the memory controller, which converts an external address applied from a system controller into an internal address for accessing the memory and replaces a defective cell in the memory with spare memory provided therein so that when a request for access to the defective cell is issued by the system controller, spare memory, rather than the defective cell, can be accessed by the system controller.
    • 提供了一种用于恢复缺陷存储单元的方法和装置。 该装置包括存储器,存储器扫描控制器,其在系统开始操作时扫描存储器以查看存储器是否有故障,并将所得到的缺陷信息发送到存储器控制器,以及存储器控制器,其将从系统施加的外部地址 控制器进入用于访问存储器的内部地址,并用其中提供的备用存储器替换存储器中的有缺陷的单元,使得当系统控制器发出访问缺陷单元的请求时,备用存储器而不是缺陷单元可以 由系统控制器访问。
