INK JET PRINTER

The present invention is an ink jet printer utilized to enlarge color images. Signals from a scanned image (50) are convened by a color correction computer (51) into control signals (54) representing the density of the individual pixels of that scanned image. The color density signals are used to control the application of ink from ink jet spray nozzles (23A-U) 25A-D) located on a pair of printheads (23, 25). Thus, the ink jet printer of the present invention reproduces the image on both sides of a translucent substrate (13) to enhance the quality of the viewed image. The present invention is further provided with dual air sources to apply the ink. A first air source (34) is pulse width modulated to control the amount of ink sprayed onto the substrate. A second air pressure source (33) is continuously applied to the ink jet spray nozzles to remove the excess ink that accumulates about the nozzles during print operations.

MANIFOLDING MEANS FOR FLAT-PLATEN TYPE-WRITERS.

Sheet conveying apparatus

In the present invention, a U-turn path is formed by facing an outer guide surface of a guide member to an outer peripheral surface of a convey roller. A terminal edge of the outer guide surface forming a part of an outlet of the U-turn path is configured not to coincide with a straight line but is tapered to be convex at a central portion. When a thick sheet is conveyed through the U-turn path, a trail end of the thick sheet is shifted to the terminal edge while rubbing the outer guide surface. Then, the trail end of the sheet leaves the terminal edge. Since the terminal edge has the tapered configuration, the trail end of the sheet is gradually disengaged from the terminal edge, thereby preventing the snapping restoring action of the trail end to weaken the shock.

MULTIPLE TEMPERATURE LEVEL REGENERATION OF CO.SUB.2 FROM PHYSICAL SOLVENT

... "MULTIPLE TEMPERATURE LEVEL REGENERATION OF CO2 FROM PHYSICAL SOLVENT" To regenerate a physical solvent, loaded with sour gases, especially CO2 and H2S, the loaded solvent is treated with a stripping gas and/or is expanded to separate absorbed CO2 and the resultant solvent is subjected to thermal regeneration to desorb H2S. To reduce energy requirements during regeneration, the CO2 desorption is conducted on at least two different temperature levels, the second being for example 30-80.degree.C higher than the first, with the first being conducted, e.g., at about those low temperatures conventional to low temperature absorption systems.

FLEXIBLE PAPER GUIDING APPARATUS

A paper guide extends around the platen of a printing machine and has a flexible extension which bears against the front of the moving printing mechanism included in the printing machine, The close proximity of the paper guide to the printing mechanism of the printing machine serves to guide the paper as closely as possible into the small gap between the printing head and the platen and also to guide the paper as accurately as possible out through the paper-exit opening of the cabinet of the printing machine. Being so closely guided (particularly in the case of multiple sheet carbon set-ups or the joints of fan-fold paper), the leading edge or a fold of the paper is less likely to catch on the ribbon or get caught on the edge of the paper-exit opening of the cabinet. The flexible final guide extends so high up the printing mechanism side of the platen that it actually bears against the printing head and is flexible deflected by the printing head as the printing head moves across the front ...

INK-JET PRINTHEAD-TO-PAPER REFERENCING SYSTEM

INK-JET PRINTHEAD-TO-PAPER REFERENCING SYSTEM Several problems of alignment associated with inkjet printers are alleviated by four aspects. In the first, a reverse bow ( ) in the paper (12) is created for printing on single sheets of paper. The reverse bow, which is in the transverse axis of the paper, forces the paper flat against the platen (12) by using the paper's own stiffness. In the second aspect, the paper and the carriage (30) are referenced to the same part (the carriage guide (10)). In this configuration, the paper is urged against the underside of the carriage guide off of drive rollers (18), through the reverse bow, and onto the platen, where it is printed. The carriage is referenced to the carriage guide through a slider bump by means of a carriage shaft and gravity. The carriage guide comprises stiff thin sheet metal, which is closely-toleranced and has well-con-trolled dimensions. Thus, this part is good to reference to, rather than molded-in parts, which are not stiff enough ...
