Title: Method and system for reproducing image
Inventor: PIITAA ERU DAFUIIRUDO
IPC: H04N9/79
Filed: 1989-12-18
Abstract: PURPOSE: To enable quick changing of the width and length of an image by providing spray heads with a device for forming 1st and 2nd menisci and a device for feeding air to the 2nd meniscus to spray ink to a medium and modulating the pulse width of air in accordance with a control signal. CONSTITUTION: The inside cross section of a branch tube 56 has the same dimensions as those of the inside cross section of an ink nozzle 38, at least on a position forming a 1st meniscus 54. The attenuation performance of a pressure surge can be improved by setting up the area of the 2nd meniscus to be at least several times the area of a meniscus formed on the end part of the nozzle 38. An image is divided into square pixels, a composite signal from a scanner 58 corresponds to one pixel in the image and a signal from the image is divided into suitable signals, expressing color components by a computer 62. These divided signals control the pulse width of an air flow, i.e., the holding of ink jets from spray heads 22a to 22d. Consequently, the width and length of an image can be quickly changed.

Title: Roll feeding device
Inventor: KATO HEIZABURO
IPC: B21D43/09
Filed: 1987-12-25
Abstract: PURPOSE:To adjust the axial line direction of a roll by aligning the plate stock to be transferred with a simple operation by rotating a deflection shaft by operating an operation means by its turning. CONSTITUTION:When a nut 11 is turned in its fastening direction, a threaded rod 10 is moved upward and a pivotally moving body 5 is pivotally moved in counterclockwise direction centering around a 1st shaft part 20a of a deflection shaft 20.
