摘要:
A self refresh circuit includes a refresh control unit and an internal refresh circuit. The refresh control unit generates a refresh control signal based on a refresh period pulse when a MRS (Mode Set Register) command is deactivated, interrupts an output of the refresh control signal based on a self-refresh-entrance inhibiting signal when the MRS command is deactivated, and generates a refresh command regardless of the refresh period pulse when the MRS command is activated. The MRS command is generated by a combination of at least one address signal and at least one control signal. The internal refresh circuit performs a refresh operation based on the refresh command. Accordingly, access time may be measured correctly and test time may be reduced.

A method and apparatus for compensating image skew and an electro-photographic image forming apparatus including the same are provided. Image skew of a toner image transferred onto a paper is compensated for by inclining a photosensitive medium onto which a light beam is scanned to be parallel to a scanning line of the light beam. A first inclination member including a first inclined surface facing upward and a second inclination member including a second inclined surface contacting and facing the first inclined surface are provided, wherein a position of a shaft of the photosensitive medium is adjusted by moving at least one of the first and second inclination members. Image skew of a toner image is sensed, and a photosensitive medium onto which a light beam is scanned is inclined to correspond to a scanning line skew of the light beam.

Disclosed is a method for using a different symbol timing for users so as to reduce a multiple access interference component in a multi-carrier code division multiple access (MC-CDMA) system. For this purpose, the presented invention involves dividing the users of the MC-CDMA system into two groups and applying an offset to the symbol timing between the user groups to cause a symbol transition of the opposite user group in the middle of the symbol interval, thereby reducing the multiple access interference component included in a symbol decision variable after a chip combination.

The cucurbituril derivatives are easily prepared as a mixture by one of the three new methods, and each cucurbituril derivative can be separated from the mixture by fractional crystallization. The cucurbituril derivatives having the formula (1) or their mixtures are very useful in removing dyes and heavy metal ions dissolved in water or waste water.
