    摘要: A memory device, system, and/or method are provided for performing a page state informing function. The memory device may compare one or more row addresses received along with a command, determine the page open/close state according to a page hit or miss generated as a result of comparison, count read or write commands with respect to pages corresponding to a same row address, and determine the page open/close state according to a read or write command number generated as a result of counting. The memory device may determine a page open/close state with respect to a corresponding page based on a page hit/miss and a read or write command number and output a flag signal. The memory device may provide the page open/close state for each channel. A memory controller may establish different page open/close policies for each channel.

    摘要: The present invention provides a separator for a fuel cell that comprises a metal substrate that contains at least one metal element M and a surface layer formed on a surface of the metal substrate and that contains at least one conductive oxide represented by LaMxO3 (wherein x=0 to 1). Also, the present invention provides a method for anti-corrosion treatment of a metallic separator for a fuel cell. The method involves first forming an La layer on a surface of a metal substrate having a desired dimension and a desired flow field formed therein. Next, the metal substrate having the La layer on its surface is heated such that at least one metal component contained in the metal substrate is diffused into the La layer and an La component in the La layer is diffused into the metal substrate to form a mixed layer composed of La and the at least one metal component on the surface of the metal substrate. Finally, the mixed layer is heated under an oxidizing atmosphere to form a layer composed of oxides containing La and the at least one metal component on the surface of the metal substrate.

    摘要: A method of controlling the position of nozzles in an ink-jet type image forming apparatus. Positional information for the nozzles at the time of print-driving the image forming apparatus is calculated by combining a first positional information with a second positional information, wherein the first positional information is measured with reference to a nozzle plate and then recorded as reference information from among various positional information for an effective detection area, which is defined as an area on a print medium measured by a light receiving part of the detection sensor in terms of the amount of reflected light. The second positional information for the effective detection area is measured with reference to a predetermined position of the print medium at the time of print-driving and is variable depending on the movement of the nozzle plate. Accordingly, the relative positional information for the nozzle plate can be accurately set, thereby more accurately controlling the position of the nozzle plate.
