Abstract: PROBLEM TO BE SOLVED: To provide a method for efficiently correcting the defects if an inkjet without waste of a system resource and a user resource.
SOLUTION: This method for inspecting the defects of an inkjet of an inkjet device includes a step (S405) to judge whether an inkjet defect inspection should be performed based on the possibilities that not less than one unit of inkjet might be defective. In addition, the method includes a step (S415) to specify the inkjet to be inspected based on the characteristics of each inkjet and a step (S420) to inspect the defect of the specified inkjet using an image sensor, in case it is judged that the inkjet defect inspection should be performed (S410). The number of the specified inkjets is less than the total number of the inkjets of the inkjet device.

Abstract: PROBLEM TO BE SOLVED: To provide a toner processing system capable of supplying low adhesive charged toner particles for the purpose of electrophotographic development. SOLUTION: Non-charged toner is collected from a fluidized bed storage chamber 76 by combined electrodes 92 and 94 on a supply body. This toner layer is charged by a corona device 300 and used to develop an electrostatic latent image 14 in a developing area 310. The remaining toner is neutralized by another corona device 400 and peeled by applying alternating current(AC) voltage between a supply body and the proximate electrodes, then it is restored to the fluidized bed. The toner particles have low adhesive force by ion charge, and are developed only by direct current(DC) electric field. The dissociation of the particles can be enhanced over the proximate electrode in the developing area 310 by the AC voltage. In addition to making the toner appropriate flow, dry powder toner is mixed interlockingly with the ion charge in the storage chamber 76, whereby ordered color development is achieved in this developing system.

Abstract: PROBLEM TO BE SOLVED: To reduce artifacts, generated by a broken or malfunctioning injector, without incorporating the other artifacts.
SOLUTION: A method for selectively printing a pixel in a printing position with a missing color comprises determining whether or not the missing color is to be printed in terms of the pixel, determining which color is to be printed according to a value of the color to be printed for the pixel, in terms of the pixel including the missing color, and selecting at least one color to be printed in place of the missing color, in accordance with at least a pseudo-random process, when the missing color is to be printed.

Abstract: PROBLEM TO BE SOLVED: To reduce deflection caused by etching. SOLUTION: Structure for a micro-device is fabricated by forming a first layer of sacrifical material, a layer of a structural material over the first sacrifical material layer, a second layer of sacrifical material over the structural material layer, and a protective layer over the second sacrifical material layer. A release etch is used to remove the first and second sacrifical material layers at substantially same rate. A structural feature is fabricated by forming a first layer of a first material, a layer of structural material over the first layer of the first material, at least one cut in the structural material layer, and a first layer of a sacrifical material different from the first material over the structural material layer such that an interface is created between the first layer of the sacrifical material and the first layer of the first material in at least one cut.

Abstract: PROBLEM TO BE SOLVED: To provide an apparatus to remove fibers and fine particles(debris) in the vicinity of the nozzles of a print head.
SOLUTION: The apparatus includes a print head protector 50 surrounding the print head, and has a first slot 60, a second slot 62 surrounding the first slot 60 and wider than the first slot. A positive pressure air supply source is connected to a suction port 64 communicating with the first slot, and an outlet 66 communicating with the second slot is connected to a negative pressure source. Air from the suction port 64 flows externally as if to separate from the print head through the first slot 60, eliminates fibers and fine particles (debris) from paper approaching the print head. The debris is captured by a negative pressure near to the second slot 62 and is removed from a printer through the outlet 66.

Abstract: PROBLEM TO BE SOLVED: To provide a capacitive electrostatic actuator or a silicon material actuator which has solved the problem that an minute electromechanical structure(MEMS) generates a electrode contact and causes damage to electrodes as a result of arc discharge after several thousands of cycles, the electrode contact is generated between the center area of an element supported to prevent contact and a certain position of the edge of thin film separated from the opposite electrode due to the sufficient deflection of a silicon thin film, and contact at the intermediate positions of these elements and subsequent arc discharge are generated in relation to an earlier deterioration and fault of a capacitor, thereby extremely shortening the operation life of the actuator. SOLUTION: The minute electromechanical type liquid exhausting apparatus is provided with an internal structure to insulate a conductor at the bottom surface of the upper part of a thin film, and an external structure to prevent contact between electrodes due to an excessive deflection of the thin film at a position isolated from the center area of the thin film of the bottom surface at the upper part of the thin film.
