Title: Printer interface device and control method
Inventor: KONDO KEIJI
IPC: B41J5/30
Filed: 1997-12-18
Abstract: PROBLEM TO BE SOLVED: To provide a printer interface device and a control method in which configuration changes are reduced both on printer unit side and on controller side and any dedicated software is not required as well. SOLUTION: In a controller 30, print data stored in a dynamic random access memory(DRAM) 301 are transferred to a copy machine 20 just for one line by a direct memory access controller (DMAC) 303 by performing burst transfer plural times while defining the burst transfer for the arbitrary number of bytes (for the unit of 8 words at a maximum) as one unit. In order to guarantee the transfer completion of all the print data for one line within the transfer time for one line specified at the copy machine 20, a DRAM controller 302 variably sets the priority of access so as to increase the DRAM access frequency of the DMAC 303 while the DMAC 303 transfers print data from the DRAM 301 to the copy machine 20.

Title: Program device
Inventor: ICHIKAWA FUMIO
IPC: G06F9/06
Filed: 1996-12-27
Abstract: PROBLEM TO BE SOLVED: To make it easy to understand a sequence and to make it easy to change parameters by incorporating a language part which specifies one subroutine and a label part which specifies detailed parameters with one label in one statement. SOLUTION: Parts which are put between [and], |and|, and [[and]] in a sheet program 'MAIN' are instructions. One instruction is divided by operators such as ':' and '<'. The former half part between [and] is an identifier indicating which of nine driver modules (IN, OUT, etc.) the corresponding instruction is an instruction language for and the latter half part is a label which should be sent to the specified driver modules and executed. A symbol 'circle' shows a conditional decision statement of a WHILE DO form. All following instruction statements below the symbol 'circle' are repeated unless the following condition on the right side of the symbol 'circle' is satisfied. Thus, one statement contains the language pat and label, so the program becomes easy to understand.

Title: Method and device for processing graphic
Inventor: YOSHIDA SHUICHI
IPC: G06F17/50
Filed: 1991-12-13
Abstract: PURPOSE:To enable an edition processing such as an envelope processing or the like even when both body graphics do not cross by editing the first and second body graphics while using the intersection of the extended body graphics. CONSTITUTION:One of the first and second body graphics as processing objects is extended at least, and the intersection of both body graphics is calculated (S3). By using the calculated intersection, the first and second body graphics are edited (S6). Therefore, even when the first and second body graphics do not cross, the first and second body graphics can be edited. On the other hand, any valid intersection is decided from the intersections calculated based on position relation between the first and second body graphics (S4), and the first and second body graphics are edited (S6). Thus, even when any intersection unwanted for edition is generated by simply extending the first and second body graphics, required edition can be surely executed and even when the first and second body graphics do not cross, the edition processing such as the envelope processing or the like can be executed.
