Abstract: When print data PD generated by applications 100 is supplied to a graphics library 110 in an order of describing objects, the graphics library 110 makes correspond print data PD to objects so as to store print data PD in a metafile 120. After print data for one page has been stored in the metafile 120, the metafile 120 is retrieved. Thus, print data PD is reconstructed for each band. A printer driver 130 converts reconstructed print data PD into the PDL data PD? so as to transfer the PDL data PD? to an output apparatus 2. A decomposer 140 does not generate intermediate format data and directly develops the PDL data PD? in a band buffer 22. An output device 24 reads raster data RD from the band buffer 22 so as to print an image on a paper sheet.

Abstract: Disclosed is a process for forming a channel wafer for a novel ink jet printhead, having an ink particle-filter layer over the ink-inlet surface thereof. The process comprises the steps of applying a thin coating of a heat-curable, photopatternable polymer composition to an intermediate substrate having a release surface and drying the coating to form a semi-solid adhesive layer. The layer and supporting substrate are pressed against the ink-inlet surface of a channel wafer with an optional adhesive layer to bond the layer to the ink inlet surface. The substrate is separated to transfer the contacting area of the semi-solid layer to the ink-inlet surface as a laminate, and the semi-solid layer is exposed through a filter-forming mask and ink particle-filter openings are developed therethrough, either before or after transfer of the semi-solid adhesive layer from the intermediate substrate to the ink-inlet surface of the channel wafer, and the filter layer is cured.

Abstract: An optical recording/reproducing apparatus having excellent resistance against vibration and noise. In recording, coherent light is polarization-modulated with a spatial light modulator to generate signal light and reference light whose polarization directions are crossed at right angles. The signal light permeates a polarizing beam splitter, and is incident to a quarter wavelength plate. The reference light passes through a passing hole, is diffused by a light diffuser and is incident to the quarter wavelength plate. The reference and signal light are converted into circularly polarized light which revolve in directions opposite to each other and condensed by a condenser lens, and then a predetermined area of an optical recording medium is irradiated with the reference and signal light. Thus, the reference and signal light are generated by modulating the incident light from the same light source and are coaxially incident to the polarizing beam splitter.
