  • Patent number: 8189026
    Abstract: A method of correcting print images in an electrophotographic printer wherein an image formed by a print head (3) on a peripheral surface of a photoconductor drum (1) is transferred and printed on a sheet of paper.

  • Patent number: 7792442
    Abstract: A electronic photograph printer includes a density-measurement section and a density controller section. The density-measurement section includes a density sensor 31 for measuring densities of images printed on a web by electronic-photograph-printing units. The density controller section adjusts densities of images which are about to be printed on the web by the electronic-photograph-printing units based on measurement data obtained by using the density sensor 31 associated with the densities of the image on the web. This configuration enables accurate and stable print-density control at a low cost.

  • Patent number: 6910403
    Abstract: To cut a protecting sheet adhered over the obverse of a wafer, an inclination angle of a cutting tool is adjusted according to a form of a chamfered part of the wafer and a finishing thickness of the wafer so that the protecting sheet is cut into the required minimum size for protecting the obverse of the wafer. Thus, the protecting sheet is not included inside a removed portion in a grinding process of the reverse of the wafer with a grindstone even if the wafer is ground to have extremely thin finishing thickness. Hence, the protecting sheet is not ground while the reverse of the wafer is ground, and the grindstone is thus prevented from being clogged up with ground material of the protecting sheet.

  • Patent number: 6782817
    Abstract: A printing machine includes two printing units, each comprising a web feed section, a web printing section connected to the web feed section and a web treating section connected to the web printing section, in which a single-side surface of a continuous web is printed at each of the web printing sections. The printing machine also includes a turn/transfer section at which two the printing units are operatively connected and the continuous web printed by one of the two web printing sections is transferred to the other one thereof through turning and transferring treatment of the continuous web. The printing machine is capable of carrying out double-side printing and single side printing and improving printing efficiency with a relatively small location space or site.

  • Patent number: 6583032
    Abstract: In a process of manufacturing semiconductor chips, first, the reverse of a wafer, on the obverse of which many chips are formed, is ground so as to shape the wafer with a predetermined thickness. Then, the reverse of the wafer is polished or etched so that the broken layer which is formed during the back grinding is removed. Next, grooves are formed on the reverse of the wafer in a predetermined depth along streets formed between the chips. Finally, the wafer is cleft along the grooves so as to be divided into separate chips. By this process, the broken layer formed on the reverse of the wafer is removed after the back grinding, then the wafer is divided into separate chips by use of the cleavage; therefore, chipping is effectively reduced.
