Title: Image forming apparatus
Inventor: HAYASHI MASAYOSHI
IPC: G06T5/00
Filed: 1988-03-10
Abstract: PURPOSE:To form halftone dot image having no light and shade irregularity and no interference irregularity by dividing color-separated image data to prede termined areas having different phases for respective colors to density-convert a pixel density in the area according to predetermined halftone dot information, and forming images of the number corresponding to the number of separated colors according to the binary signal responsive to the density. CONSTITUTION:After input video data Y, M, C, BK are used as they are or converted to halftone dots for respective colors to combine the part with a font pattern in a printer 2000, they are density=pulse width (PWM)-modulated. This PWM-modulated binary signal is formed in a horizontally (mainly) scanning beam at a high speed by a polygon mirror 2289 by driving a laser beam, and dot-exposed corresponding to the video data on the surface of a photosensitive drum 2900. In this case, a quiet Y component for its spectral luminous efficiency is set to a screen angle near 0 deg. so that a moire is scarcely observed, and a BK component is so corrected at its data that a further lower density area than the minimum values of the color components is not read as its density in a reader. Thus, even if a black color is set to an angle near 0 deg. or 90 deg., a moire with a pitch irregularity is scarcely observed.

Title: Semiconductor memory
Inventor: KOMATSU TAKAHIRO
IPC: G11C11/403
Filed: 1988-03-08
Abstract: PURPOSE:To simplify the design and the control of a memory system by performing self-refresh for every divided memory cell arrays in the number smaller than the number of refreshes performed at the time of normal working state. CONSTITUTION:A control signal rises up to an H level from a L level with the rise of the L level of a refresh control signal used as a trigger. As a result, a transfer gate Tr1 is turned on with a Tr2 turned off respectively. Thus a column address signal CA9 is invalidated and a row address signal RA9 obtained by a refresh address counter 4 is validated. Therefore, only a sense amplifier of either one of four blocks is activated by the row address signal obtained by the output of the counter 4. Thus the peak value of a bit line charging/ discharging current IB3 is reduced at the self-refresh in a single refresh cycle. As a result, the design and the control of the system can be simplified.
