20090141827DATA TRANSFER BETWEEN CHIPS IN A MULTI-CHIP SEMICONDUCTOR DEVICE WITH AN INCREASED DATA TRANSFER SPEED - A data transfer method is disclosed in a multi-chip semiconductor device which comprises a plurality of inter-chip wires. First, a test is conducted to determine whether or not each inter-chip wire is capable of normally transferring data, on circuits arranged on chips between which the inter-chip wire is connected. When an inter-chip wire incapable of normally transferring data exists, the data transfer speed of the buffer circuit that is on the chip on the transmission and that is connected to an inter-chip wire capable of normally transferring data is increased. The buffer circuit, whose data transfer speed has been increased, transfers data which would otherwise be transferred through the inter-chip wire incapable of normally transferring data, together with the data which should be transferred thereby, to the chip on the reception side chip through an inter-chip wire connected to the buffer circuit at the data transfer speed.06-04-2009

20080273907Positional-deviation correction apparatus, method of controlling positional deviation, and image forming apparatus - A first correction pattern and a second correction pattern are formed on an endless conveyor belt. The first correction pattern is located ahead of the second correction pattern on the conveyor belt with respect to the direction of movement of the conveyor belt. A sensor detects positional information of the correction patterns. A timing changing unit (controlling unit) changes a detection timing of the second correction pattern from a time point at which the sensor detects the second correction pattern.11-06-2008
20080304840IMAGE FORMING APPARATUS - A misregistration correcting unit correcting image misregistration on an endless belt in an electrophotographic image forming apparatus is disclosed that includes an image creation part that creates on the endless belt misregistration correction pattern sets each including a pattern of mark groups each being one of a horizontal line mark group formed of horizontal line segment marks and an oblique line mark group formed of oblique line segment marks; a position detecting part that detects the mark positions; a position detection counting part that counts the number of the detected positions of each mark group and detects an abnormal mark group whose number of the detected positions is other than a prescribed number; a detection result storing part that stores information on the detected mark positions; and a misregistration calculating part that calculates the amount of misregistration based on the stored position information excluding that of the abnormal mark group.12-11-2008
20090161142Positional Error Detection Method and Apparatus, and Computer-Readable Storage Medium - A positional error detection method forms, on a belt which is transported in a transport direction, positional error detection marks for detecting a positional error between image positions of first and second colors, detects the positional error detection marks on the belt, and computes the positional error based on the detected positional error detection marks. The positional error detection marks include first and second marks which are inclined in mutually opposite directions with respect to the transport direction, and third marks which are perpendicular to the transport direction.06-25-2009
20090213399IMAGE FORMING APPARATUS, MISREGISTRATION CORRECTION CONTROL METHOD AND COMPUTER-READABLE INFORMATION RECORDING MEDIUM - A pattern image of either a registration correction pattern including a plurality of position detecting marks or a misregistration correction performing determination pattern having a plurality of position detecting marks, the number of which marks is smaller than that of the registration correction pattern image is formed. A misregistration amount is calculated based on an image formed position detected with the use of the pattern image. It is determined whether the registration correction is to be carried out, based on the misregistration amount with the use of an image formed position of the correction performing determination pattern. When it is determined to carry out the misregistration correction, the misregistration correction is carried out based on the misregistration amount with the use of image formed positions of the misregistration correction pattern.08-27-2009

20090072414BONDING METHOD OF SEMICONDUCTOR AND LAMINATED STRUCTURE FABRICATED THEREBY - A bonding method (three-dimensional mounting) of semiconductor substrates is provided to sequentially bond a principal surface of a silicon wafer on which coupling bumps are formed, and a principal surface of the other silicon wafer on which pads are formed, by an adhesive applied to at least one of the principal surfaces. However, there is a problem of poor electrical coupling due to displacement of the bumps and the pads when bonded together. The present invention solves such a problem by conducting temporary positioning of the silicon wafers, adjusting the positions of the coupling bumps and pads while confirming the positions by a method such as x-ray capable of passing through the silicon wafers, and bonding the bumps and the pads together while hardening an interlayer adhesive provided between the principal surfaces of the silicon wafers by thermocompression.03-19-2009
