    • The present invention relates to a method for producing a cellulose solution which is homogeneous at low temperatures, and to fiber produced by the method. More particularly, the invention relates to a production of a cellulose solution which is homogeneous at low temperatures, by dissolving a small amount of the cellulose powder in concentrated liquid N-methylmorpholine-N-oxide (NMMO) to lower the solidification temperature of NMMO, introducing the low-temperature, concentrated liquid NMMO solution having cellulose dissolved and the cellulose powder into a kneader, mixing and swelling the cellulose in the kneader without a process of reducing pressure to produce a paste, and then supplying the paste into an extruder to dissolve the paste in a homogeneous solution.

    • The Disclosed is a method of reading a memory device in a page mode. The method includes the steps of inputting a row address for selecting the word line, enabling a corresponding word line by the row address, and reading/restoring the level of the cell node connected to the enabled word line, and disabling the enabled word line and sequentially enabling bit line sense amplifiers connected to the disabled word line to perform a read operation, wherein the disabling of the selected word line is performed after a lapse of a certain time period as much as data of a first cell node can be restored. Therefore, it is possible to reduce current consumption in a read operation of a page mode.
    • 所披露的是以页面模式读取存储器件的方法。 该方法包括以下步骤:输入用于选择字线的行地址,通过行地址启用相应的字线,以及读取/恢复连接到使能字线的单元节点的电平,以及禁用所启用的字线,以及 顺序地使连接到禁用字线的位线读出放大器执行读取操作,其中所选择的字线的禁用在经过一定时间段之后执行,可以恢复第一小区节点的数据。 因此,可以减少页面模式的读取操作中的电流消耗。

    • The present invention relates to a high tenacity, high modulus and low shrinkage lyocell multifilament yarn suitable for use in tire cords and MRG (mechanical rubber goods). The lyocell multifilament yarn is a cellulose-based fiber for industrial applications, which is produced by dissolving pulp having a degree of polymerization (DPW) of 700-2,000 and preferably 800-1,400, and a α-cellulose content of more than 90% and preferably more than 92%, in N-methylmorpholine N-oxide (NMMO) hydrate, at a pulp concentration of 5-15% by weight and preferably 8-13% by weight.The lyocell monofilament according to the present invention is characterized by the following stress-strain profile: (1) the lyocell monofilament analyzed after drying is elongated by less than 3.0% and has an initial modulus of 150-400 g/d, when it was subjected to an initial stress of 3.0 g/d; (2) it is elongated by 3.0-7.0% when it was subjected to a stress greater than the initial stress but smaller than 6.0 g/d; and (3) it is elongated from a tensile tenacity of at least 6.0 g/d until the yarn is broken.
