Abstract: An object, such as a container cover, is lined on a predefined area of the object by depositing powder on the predefined area. The lining material is formed into a non-spherical powder having a resting angle of 40 degrees or greater. The powder is deposited by fluidizing the powder in a feeder using vibration and conveying the powder through a nozzle to the predefined area. The powder layer deposited on the object is pressed with a molding element to form a lining layer having the predefined shape. The lining thus formed has a predefined thickness distribution and shape with good tightening and sealing properties and corrosion resistance. In addition, no environmentally unsafe processes are required for the precise deposition of powder.

Abstract: A device for printing an image onto a surface, such as food containers, employs a laser that is scanned across a surface to produce a latent image on a charged photosensitive surface formed on the surface. The surface is moved relative to the laser source while the laser is activated and deactivated according to a pattern of signal pulses from a control circuit. The device thus forms a raster image. To form very fine images, the control circuit must produce pulses with very small steps in duration. The control circuit of the present invention divides a digital value representing a duration of firing of the laser into high and low order bit sequences. The high order bits, representing a value M, are applied to a counter that generates a first pulse M clock cycles long. The low order bits and the first pulse are applied to a delay circuit. The delay circuit generates a delayed version of the first pulse, which is delayed by an amount represented by the low order bits.

Abstract: Dots for producing a multiple tone electrostatic latent image are formed by selectively discharging a charged surface with a scanned laser beam. The multiple tones are produced by pulse width modulation of the laser beam according to the tones required in the dots. High resolution is maintained by limiting the diameter of toner particles to 1/5 to 5 times a minimum exposed dot dimension of less than 1 micron. A laser beam exposure device includes a galvanometer mirror from which the scanning laser beam is reflected. The galvanometer mirror is tilted in synchronism with the conveying direction of the surface being scanned in order to maintain focus of the laser beam on the surface.

Abstract: A multicolor printing method for printing multicolor picture images upon a material or object to be printed comprises the steps of, in accordance with a first embodiment of the invention, the formation of a multicolor toner image upon a flexible belt by means of electrophotographic printing methods or techniques, and the transfer of such multicolor toner image directly to the material or object to be printed, such as, for example, a container made of, for example, metal, paper, plastic, glass, or the like, by means of a thermo-transferring process. In accordance with a second embodiment of the invention, the multicolor toner image is formed upon a plastic film, which is laminated upon the flexible belt, by means of electrophotographic printing methods or techniques, and the plastic film is then transerred to and fused upon the container.

Abstract: Toners are sticked on a thin plate metal or a metallic container by electrophotographic-printing units (3), (4), and (5), and during the sticking processes, the toners are preliminarily fixed with a lower temperature and finally fixed with a higher temperature, thus being printed. A photoconductive material layer can be directly laminated on the surface of the thin plate metal or the metallic container or is disposed on a drum. A firm printed surface can be obtained by coating a finishing vanish on the toners.
