Filed: 2000-06-26
Abstract: PROBLEM TO BE SOLVED: To provide an image-forming device, capable of more stably forming an image by forming a patch image taking into consideration the influence exerted on the image by a toner flow hindering part provided in a developing device. SOLUTION: After a patch latent image PI is formed on a photoreceptor 21 so that at least a part of the patch latent image PI crosses with a part of a virtual area VR, it is developed with toner by developing devices 23Y, 23M, 23C and 23K, whereby the patch image is formed. Because of this, a part of the toner to be supplied to the patch latent image PI is carried via the area VR, so that influence by a spring peg part 230, that is, the change of image quality because of the unevenness of tone flow is reflected in the patch image. Therefore, the image is formed more stably by adjusting density by using the patch image.

Title: Semiconductor storage device
Inventor: TAKASHIMA DAIZABURO
IPC: G11C14/00
Filed: 2000-07-11
Abstract: PROBLEM TO BE SOLVED: To reduce a chip area and also process cost by applying hierarchical word lines and a hierarchical block selection line method without increasing distribution layers. SOLUTION: Main block selection lines MBS0 and MBS1 connecting a main row decoder MRD and a sub row decoder SRD are composed by using memory cells in a cell block, a metal line CI used between the memory cells and the distribution layer that is the same as plate lines PL, /PL. The process cost can be reduced because a distribution layer does not have to newly be provided even though the hierarchical word lines and the hierarchical block selection line method are applied. Thus, a decoder circuit for deciding to select which cell block in an array becomes unnecessary for the sub row decoder and a chip size can be reduced. A sub array size can also be made small by making a sub row decoder area small, and acceleration can be realized due to the reduction of power consumption and the delay time reduction of the word lines and the plate lines.
