Title: Method for making an integrated circuit including alignment marks
Inventor: MAURY ALVARO
IPC: G03F9/00
Filed: 2000-02-16
Granted: 2001-08-01
Abstract: A method for making an integrated circuit preferably includes the steps of: forming a trench laterally adjacent an active region in a semiconductor substrate; forming a dielectric layer on the semiconductor substrate filling the trench and covering the active area; selectively etching the dielectric layer to remove at least a portion of the dielectric layer overlying the active region and to define a recess within the dielectric layer filling the trench to serve as an alignment mark; and polishing the selectively etched dielectric layer and leaving the alignment mark. The method may also include forming an optically opaque layer adjacent the polished dielectric layer and with the alignment mark causing a repeated alignment mark in the optically opaque layer. The alignment mark and/or repeated alignment mark may be used for alignment in a subsequent processing step. The alignment mark can be made with a step height which is greater than a conventional alignment mark formed by the step height difference between the active area and the dielectric layer of the trench. Accordingly, variations in polishing, for example, will not obscure or remove the alignment mark made in accordance with the present invention.

Title: Circulating type food and drink transport apparatus
Inventor: ISHINO YUICHI
IPC: A47F10/06
Filed: 2000-10-04
Granted: 2002-10-21
Abstract: In a circulating type food and drink transport apparatus, since a first magnet and second magnets are disposed such that the same magnetic poles thereof confront each other, when a food and drink vessel is placed on a transport path, the first magnet faces the second magnets through the same polarities. Thus, the first magnet is subjected to the repulsive force of the second magnets, whereby the food and drink vessel tends to be stably located between adjacent magnets of the second magnets. When the second magnets are circulatingly traveled in a predetermined direction, the first magnet circulatingly travels at the same speed as the traveling speed of the second magnets because it tends to secure the above stable position. Since the repulsive force exists between the second magnets and the first magnet, the food and drink vessel can be taken up with a relatively small amount of force as well as it is made difficult for the transport path to be scratched by the food and drink vessel when it is circulatingly transported.

Title: Display control apparatus having replaceable color palette
Inventor: SASAKI TORU
IPC: G09G5/06
Filed: 2001-03-30
Granted: 2002-09-01
Abstract: A display control apparatus contains a video memory (11), a video memory controller (12), a color palette memory (13) and a color palette replacer signal generator (15). The video memory stores display data that are read from a CD-ROM and contain header data (HA-HD), palette data (PO-P2) and bitmap data (BA-BD) in connection with four planes which are combined together to form one frame of picture. The header data contain a color palette pointer (CPP) and a color palette replacer instruction (CPP31) with respect to each of the planes. The video memory controller reads the palette data and bitmap data from the video memory in accordance with addresses designated by the header data. The color palette replacer signal generator generates a color palette replacer signal (COL) based on the header data so as to make determination whether to replace contents of color palettes with respect to the planes respectively. If the color palette replacer instruction designates color palette replacement, the video memory controller unconditionally replaces previous palette data with present palette data on the color palette memory. If the color palette replacer instruction does not designate color palette replacement, the video memory controller replaces the previous palette data with the present palette data on the color palette memory only when a present color palette pointer designating the present palette data differs from a previous color palette pointer designating the previous palette data. Thus, it is possible to considerably reduce time for replacement of contents of the color palettes.
