Abstract: To provide a laser plate making apparatus having a simple construction capable of reducing generation of Moire. The slant line R1 formed of the starting position of the formed arbitrary recess 7 which is formed on the press plate 5a or the like in the main scanning direction F is formed so as not to be coincident with the slant line R2 formed of the starting position in the main scanning direction F of the recess 7 which is located at the next position in the sub scanning direction A. Therefore, when a multicolor printing is carried out by using the press plate 5Pa thus formed or the like, manifestation of Moire is reduced. Particularly, when the line R3 connecting the predetermined point within the arbitrary recess 7 to the point located at the position corresponding to the predetermined point in the recess 7 which is located at adjacent position in the sub scanning direction A, is set to a constant angle .phi. different from the irradiation angle .theta. of the laser beam, the Moire is further reduced.

Abstract: A color filter for an AMLCD panel has a pattern of multi-color dots, each dot having red, green, and blue components in a black matrix. Each component is the cured product of a color pigment dispersed in a radiation-curable ink. The ink may be an ink curable by a cationic mechanism, a free-radical ink, or a hybrid, free-radical/cationic ink. The filter is produced by successively applying patterns of colored inks to a transfer roll, collecting the patterns on a collector roll to form an array of multi-color dots that is transferred to the substrate, and irradiating the array of dots to at least partially cure the inks.

Abstract: A method and apparatus for printing a multi-color ink pattern on a substrate surface which comprises arranging a series of patterned surfaces with each patterned surface having a pattern that is unique to one of the colors and that corresponds to the pattern of that color in the multi-color pattern, supplying to each patterned surface a radiation-curable ink formulation, having an appropriate colorant to form an ink pattern thereon, transferring individually the color pattern from each patterned surface to a collector roll, increasing the cohesiveness of the ink sufficiently to permit complete transfer of the pattern, forming a composite of the color patterns on a collector roll, and transferring the composite pattern in its entirety to the substrate surface.

Abstract: A printing method for an in situ plate production process in which a photosensitive plate blank having a polymerization layer between a support and a release film is fixed to a plate cylinder either before or after forming a polymerization-nonpolymerization pattern in the polymerization layer. The polymerization layer can be a thermal development-type photosensitive layer for forming the pattern. The release film is then peeled apart from the plate blank to leave a printing plate on the plate cylinder, which can be used for printing and for an inking step. The printing pattern of the plate can be formed by selective removal of the unpolymerized part or by selective transfer of the release film to the polymerized part of the polymerization layer.

Abstract: An orthodontic assembly that includes a band and an attachment has one or more spot welds to secure the band to the attachment.

Apparatus for welding the attachment to the band includes a subframe that is swingable in an arc to follow the inner contour of the band in order to provide automated welding on mesial and distal sides of the attachment.

Abstract: Bottles are decorated while advanced by intermittent motion to each of a plurality of decorating stations where a squeegee presses a decorating screen into line contact with a surface of the bottle which has a speed the same as the speed of which the decorating screen is advanced along the printing station. The bottles are decorated at a higher through put rate by initiating linear movement of the screen before the bottle arrives at the decorating station and continuing linear movement of the screen after the bottle moves from the decorating station. The degree of overlap allows the printing cycle to consume a major part of a machine cycle while the bottle indexing cycle consumes a minor part of the machine cycle. The bottles are received in a vertical orientation and intermittently re-orientated horizontally for entrance to the decorating machine.

Abstract: A device is provided which creates aerosolized particles by forcing a formulation of drug in a carrier through a nozzle (which nozzle may be in the form of a porous membrane) into a channel to a patient for inhalation. While in the channel energy is added to the particles in an amount sufficient to evaporate carrier and thereby reduce particle size. The amount of energy added can be adjusted depending on factors such as the particle size, the amount of the carrier to be evaporated, the water vapor content of the surrounding air and the composition of the carrier. Energy may be added in an amount sufficient to evaporate all carrier and thereby provide particles of dry powdered drug to patient which particles are uniform in size regardless of the surrounding humidity and smaller due to the evaporation of the carrier.

Abstract: A method is provided for using a pad printing device to decorate a base surface with an image. Initially the form of the image is printed on the base surface using a base coat material which has a sufficiently high adhesion with the base surface. An ink image is then printed in registry with the base coat image using an ink which has a sufficiently high adhesion to the base coat material. The image is then printed in registry with the ink image using a top coat material which has a sufficiently high adhesion to the ink. Because each layer of material has a sufficiently high adhesion to the adjacent material, the resulting decorative label has a high adhesion to the base surface.
