Title: Method for rastering half-tone images
IPC: G03F5/24
Filed: 1982-07-29
Granted: 1986-10-08
Abstract: According to the method for rastering half-tone images, grey values of the image are reproduced by modifying the structure density of a base raster structure selected according to the form. The attribution of the field of grey values of the half-tone image to the raster structural density reproducing said field of grey values may be fixed appropriately. In a phototechnical version of the method (Fig. 1), there is obtained a selected base raster structure (1) and from the latter enlarged raster structures are produced as negative films (9, 11). From the image to be rastered (13), there is produced, as negative films, a same number of extracts of tone values (20, 22), each of them reproducing a predetermined field of grey values of the half-tone image, fixed by means of the exposure time. The extracts of tone values (22, 20) are exposed on a support (24), with the raster structures (9, 11) of the series to which they are attributed. The support then reproduces the rastered image in a form such that the grey values portions determined by the extract of tone value are locally reproduced by the raster structural density attributed to them. There are a plurality of alternatives in the photographic technics and in the laser technics, implementing said method, which are appropriate for the rastering of half-tone images, for the production of half-tone blocks and for printing reproduction supports with images thus rastered.

Granted: 1987-04-08
Abstract: An optical storage medium for the storage of information is produced by employing a material (4) having a solid matrix upon irradiation with a suitable form of energy undergoes a generation or increase of gas pressure within a solid matrix. To write information in the medium, energy is directed to a localized area. The energy, if appropriately chosen, produces a desired gas pressure which deforms the surface (8) of the medium in the localized area. Indeed, if sufficient energy is applied, the gas pressure is sufficient to remove (11) the material in the localized area. Either the removal of material or the production of a surface irregularity produces an optically observable change relative to the unexposed regions of the medium. In this manner, it is possible to store information in the medium. Upon reading, using standard techniques, a high signal to noise ratio signal is obtainable.

IPC: B05D1/02
Filed: 1984-08-28
Granted: 1987-12-02
Abstract: Solid films are deposited, or fine powders formed, by dissolving a solid material into a supercritical fluid solution at an elevated pressure and then rapidly expanding the solution through a short orifice into a region of relatively low pressure. This produces a molecular spray which is directed against a substrate to deposit a solid thin film thereon, or discharged into a collection chamber to collect a fine powder. Upon expansion and supersonic interaction with background gases in the low pressure region, any clusters of solvent are broken up and the solvent is vaporized and pumped away. Solute concentration in the solution is varied primarily by varying solution pressure to determine, together with flow rate, the rate of deposition and to control in part whether a film or powder is produced and the granularity of each. Solvent clustering and solute nucleation are controlled by manipulating the rate of expansion of the solution and the pressure of the lower pressure region. Solution and low pressure region temperatures are also controlled.

Abstract: Image processing apparatus for increasing the gray scale resolution of a graphic generated by an ink jet printing system wherein the graphic is made up of pixel areas on a receiving surface and each pixel area is comprised of a fixed number of potential dot positions printed with substantially equal sized dots. A sequential series of image density signals representative of the grey scale color intensity is generated from an original graphic and converted to a dot level value for each pixel. A pixel's dot level value is compared to a set of integer and non-integer values and pixels having dot levels falling between the same two sucessive integer values are selected. A predetermined dot level value is alternately added to the identified adjacent pixels so that one is increased and the other is decreased by the predetermined dot value. The resulting values are rounded off to the nearest integer and each pixel is printed with its respective new value. The resulting gray scale color intensity represented by the two printed pixels is the average of the sums of the two printed pixels' dot level values.
