Abstract:
PROBLEM TO BE SOLVED: To maintain uniform shaft temperature along the entire cylindrical surface 130 of a heated fuser roller. SOLUTION: A ferromagnetic layer is bonded to, or coated on, or in other manner applied to, the surface of a heatable fuser memberfor fusing dry toner in an image forming device. The ferromagnetic layer promotes inductive heating of the heatable fuser member based on high hysteresis loss exhibited when the ferromagnetic layer is exposed to a magnetic field created by the current flowing through an induction coil or other like device. Suitable materials for the ferromagnetic layer are those which exhibit a high coupling efficiency to the imposed magnetic field. A result is substantially controllable, consistent heating of the heatable fuser member to fuse dry toner onto or into the image bearing surface of an image receiving medium.

PROBLEM TO BE SOLVED: To minimize a current necessary to heat a heat generating component to a target temperature, to simplify system design; and to minimize the cost of electrical and electronic hardware in the system. SOLUTION: The induction fixing system includes a heating component 300 configured to come into contact with an image-receiving substrate and to fuse a toner stuck to the image-receiving substrate, and to include susceptor layers 315 and 320 comprising a plurality of carbon nanotubes, and an electrical coil 135 positioned at a proximate distance from the heating component 300 and configured to carry a current. When the current is applied to the electrical coil 135, the current through the electrical coil can inductively heat the susceptor layers 315 and 320. COPYRIGHT: (C)2011,JPO&INPIT

Abstract:
PROBLEM TO BE SOLVED: To provide an image forming system that greatly shortens setup time required for a color adjustment process and, at the same time, enables a robust pantone (R) print. SOLUTION: The image forming system 10 for forming an image in a requested color on a substrate has a conditioning station 18 which conditions toner before the image is formed on the substrate, a drawing device 20 which draws part of the toner from the conditioning station 18, and a controller 22, connected to the drawing device 20 which transmits a signal for the formation of the image on the substrate when the drawn toner is suitable for the generation of the requested color.

Abstract:
PROBLEM TO BE SOLVED: To provide a sheet feeder capable of changing inclination of a sheet support tray on which a sheet stack is placed. SOLUTION: A sheet support tray 210 on which a sheet stack is placed is supported by two tray elevators 220, 230. Each of the tray elevators can independently make the sheet support tray 210 ascend and descend to consequently change inclination of the tray 210. It is possible to provide a paper feeder capable of corresponding to ream weight of various paper sheets, types and curls by controlling the height and the position of the stack.

PROBLEM TO BE SOLVED: To provide a design of a stepped nozzle in which an ink droplet size can be regulated independently from droplet velocity and the necessity of the complicated design optimization is reduced.SOLUTION: An inkjet printer includes: a print head configured to receive ink; and one or more stepped nozzles provided with the print head. The one or more stepped nozzles have an exit diameter which is set so as to regulate the droplet size of ink to be ejected and an entrance diameter which is set so as to regulate the velocity of the ink droplet to be ejected independently from the size of the ink droplet to be ejected.
Abstract:
PROBLEM TO BE SOLVED: To provide an inkjet printing system that independently control the mass and speed of ink liquid drops ejected from an inkjet print head. SOLUTION: A taper angle 330 depends on relationships among an exit diameter 310, an inside diameter 315, and/or thickness 325. For example, when the thickness 325 is fixed, the taper angle 330 can get larger as the difference between the exit diameter 310 and the inside diameter 315 is increased. Likewise, when the thickness 325 is fixed, the taper angle 330 can get smaller as the difference between the exit diameter 310 and the inside diameter 315 is decreased. The different values of and adjustments among the exit diameter 310, the inside diameter 315, the thickness 325, and the taper angle 330 can dictate the mass and speed of ink liquid drops that exit the nozzle 305. Further, they can allow the mass and speed of liquid drops to be independently dictated by the exit diameter 310 and the taper angle 330, respectively. COPYRIGHT: (C)2011,JPO&INPIT
