Inventor: KALLIOKOSKI MATTI TUOMAS
IPC: D21H17/28
Filed: 1998-04-06
Abstract: There is disclosed a method for sizing paper by adding to the surface of the paper a sizing composition comprising a rosin and a 2-oxetanone. The sized paper performs better in ink jet printing than does paper that is the same except that the size composition contains only rosin or only 2-oxetanone, when the printing is evaluated for at least one property selected from the group consisting of optical density, feathering, wicking, edge roughness and bleed. The sized paper also has higher toner adhesion, a higher coefficient of friction and a lower coefficient of friction bandwidth than does paper that is the same except that the size composition contains only 2-oxetanone. The paper is also capable of performing effectively in tests that measure its convertibility on state-of-the-art converting equipment and its performance on high speed end-use machinery.

Abstract: An integral headwall structure constructed of lightweight reinforced composite and incorporating a rigid polymer concrete core in selected portions, for use with standard culvert or drainage pipes in infrastructure water management systems in substitution for conventional concrete headwalls. The headwall structure has a vertical back wall with an integral pipe stub surrounding a central orifice. The pipe stub is preferably cross-sectionally dimensioned and configured to be identical to a selected standard pipe section end so that such pipe section can be connected to the pipe stub without an adapter. A tray is joined to the lower edge of the back wall. A pair of outwardly flared sidewalls are joined to the back wall and to the tray. Angled brace panels extending from the sidewalls to the tray reinforce the sidewalls. The tray, sidewalls and brace panels define the water channels. Front and side brace panels define a recess into which earth enters and against which earth bears to provide stabilization. The sidewalls and all or selected ones of the brace panels may be curved to form a curved continuum.

Title: Method and apparatus for detection and correction of illumination flicker
Inventor: KASAHARA MISA
IPC: H04N5/235
Filed: 2000-10-06
Abstract: A video signal including illumination flicker component is integrated at each of unit areas (horizontal lines) in a frame (field) of the video signal. The integrated level at each of the unit areas at the frame and the integrated level at the corresponding unit area of an adjacent frame are averaged. Dividing is effected between results of the averaging and integrating every unit area. It is judged whether flicker exists in the video signal by frequency-analyzing results of the dividing result at the unit areas. The unit area may be plural adjacent lines where flickering are negligible. The averaging circuit may be circulation type of or FIR filter. Threshold level for judging the flicker is changed according to a shutter speed control signal. Flicker compensation may be executed by controlling shutter speed or the AGC according to flicker judging result. A still condition at a block in a frame may be detected from the integration result at plural frames. When the block is judged to be still, the flicker is judged. An ac line frequency detection is also disclosed to detect the frequency of the ac line from a video signal generated under illumination including flicker. An imaging circuit may be provided to generate the video signal therein.
