A semiconductor device includes a memory cell array including a plurality of memory blocks, a control logic, a level shifter configured to generate a first internal voltage and a second internal voltage lower than the first internal voltage using a received external voltage on the basis of a control signal from the control logic, and a row decoder configured to provide the first and second internal voltages generated by the level shifter to the memory cell array. The level shifter generates the first internal voltage using the external voltage, generates the second internal voltage using the generated first internal voltage in a power-up mode of the semiconductor device, and generates the second internal voltage using the external voltage in a standby mode of the semiconductor device.

The present invention relates to a flip cover plate () for a mobile terminal, the plate comprising: a cover plate inserted into a flip cover which opens and closes the front portion of the mobile terminal; and a transparent window coupled to one side of the cover plate and exposing a portion of a liquid crystal of the mobile terminal to the outside when the flip cover is positioned at the front portion of the mobile terminal, wherein the transparent window is configured to be bonded to at least one surface of the cover plate corresponding to in opening of the flip cover. Accordingly, the present invention has an advantage of maximizing productivity compared to production through one by one cutting processes by means of a conventional numerically controlled machine tool. Furthermore, since the transparent window is not simultaneously molded when the cover plate is injection-molded, the present invention has advantages of simplifying the shape of a mold, thereby being capable of reducing manufacturing costs, as well as reducing manufacturing time and also the failure rate of products since the manufacturing of parts proceeds in parallel.

The present invention provides a method of manufacturing Ni-doped TiOnanotube-shaped powder and a method of manufacturing a sheet film to be inserted into a high-pressure hydrogen tank for a fuel cell vehicle by mixing the Ni-doped TiOnanotube-shaped powder with a binder and compressing the mixture. The method of manufacturing Ni-doped TiOnanotube-shaped powder includes: forming Ni-doped TiOnanotube-shaped powder using Ni-doped TiOpowder as a starting material; and drying the Ni-doped TiOnanotube-shaped powder in the temperature range of 60 to 200&#xb0; C. for 2 to 24 hours.

The present invention relates to novel cephem compounds having the formula: ##STR1## wherein, Q is a carbon or nitrogen atom; X is an oxygen atom, or a nitroalkyl or cyanoimine group, with the proviso that X cannot be an oxygen atom when Q is a carbon atom; R.sub.1 is a hydrogen atom, or a lower alkyl group, or a lower alkyl group which may be substituted by fluoro, or by a carboxylic group or an inorganic cation salt thereof; and R.sub.2 and R.sub.3 independently are a hydrogen atom or a lower alkyl group; or pharmaceutically acceptable salts thereof. The compounds of the present invention have potent antibacterial activities against gram-negative bacteria, especially Pseudomonas, and a longer half-life than conventional cephem compounds.
