A method of manufacturing an ink cartridge for use in an ink jet recorder, comprising the step of providing an ink bag having a top end, and a bottom end below the top end, the top end being open and the bottom end having an ink feed port therein; moving the ink bag from a first position near a top edge thereof and positioning the ink bag in a vacuum chamber; depressurizing the vacuum chamber; charging a selected quantity of ink into the ink bag; sealing the open end of the ink bag at a second position below the first position; pressing the sealed portion of the ink bag to a selected thickness with press plates; sealing the bag in the pressed position at a third position below the second position; and cutting the ink bag between the second and third positions.

A method of refilling an ink bag that is used in an ink jet recorder, the ink bag is initially filled with ink through an opening in the bag, and is sealed after the ink bag is initially filled. The method comprises the steps of removing the ink bag from the ink jet recorder, positioning the ink bag, inserting an ink needle into a separate opening in the ink bag that is different than the first opening through which the ink bag is initially filled with ink, discharging ink from the ink bag through the second opening, and charging the ink bag through the second opening with a specified quantity of ink.
摘要:
A method of refilling an ink bag of an ink cartridge for use in an ink-jet recorder. The method includes first removing the ink cartridge and ink bag from the ink-jet recorder. The ink bag may then be refilled by positioning the ink bag on a surface, inserting an ink needle into a port of the ink bag, and by discharging ink from the ink bag and charging the ink bag with a specified quantity of ink.

According to one embodiment, a video server includes a plurality of processors and a log data integration unit. Each of the plurality of processors includes a generation module, a storage module, and a transmission module. The generation module generates the log data including at least an event occurrence time. The storage module stores the log data. The transmission module transmits the log data stored in the storage module to the log data integration unit via the common bus. The log data integration unit includes a reception module and an integration module. The reception module receives the log data from the plurality of processors via the common bus. The integration module integrates the received log data in an occurrence time order.

A photosensitive resin film 6 is pressed onto the surface 2 of nozzle plate 1, with one portion entering the inside of nozzle 4. Then, by ultraviolet radiation directed from the rear surface 3 of nozzle plate 1, the inside the nozzle portion hardened as to form a plug 6a, and at the same time the portion of photosensitive resin film directly above nozzle 4 is hardened by the ultraviolet radiation to form an extensive portion 6b, of a size at least that of nozzle diameter d, but no larger than 1.4 times that of nozzle diameter d. Finally, using the shape of extensive portion 6b, an ink-repellent eutectoid plating coating layer 8 is applied to the whole surface 2 of nozzle plate 1 with the exception of the edge of nozzle 4 covered by the extensive portion, forming on that surface 2 a water-repellent surface that does not cause deviation in the flight of ink droplets, while restricting the lining of the inside of nozzle 4 with the coating layer.
摘要:
A nozzle plate free from stray fly and defective jetting is achieved by a method which has a first step of putting a photosensitive resin film 5 in pressure contact with a back surface of a nozzle plate 1. A part of the photosensitive resin film 5 is caused to step into a nozzle 4 by controlling the viscosity thereof by changing temperature. Then, the thus processed photosensitive resin film 5 is hardened by injecting ultraviolet rays thereto. Next, a front surface 2 of the nozzle plate 1 is subjected to a eutectoid plating 6 process. By regulating a step coverage d of a part of the eutectoid plating 6 into the nozzle 4 by the hardened photosensitive resin film 5, a-nozzle plate having consistent nozzles, each being free from stray fly and defective jetting can be formed.

An ink jet recording apparatus including an ink jet recording head 1 that is shuttled by a carriage 4 and jets ink droplets in synchronism with a print signal, a capping device 8 to which a negative pressure of a sucking pump 10 is supplied, a first ink tank 12 that communicates with the atmosphere through an opening 14 and contains a printing ink, a second ink tank 13 that contains ink in a degassed condition, a selector valve 16 that selectively connects the first and second ink tanks to the recording head, and a controller 20 that controls the selector valve 16. Ink in the first ink tank 12 or the second ink tank 13 is discharged out of the recording head 1 by causing the capping device 8 to apply negative pressure to the recording head 1 during a cleaning operation of the recording head 1.
摘要:
A recording sheet has a base and a receptive layer disposed on at least one surface of the base. The receptive layer contains at least a water-absorbent copolymer and said water-resistant graft copolymer whose main chain is polyvinyl alcohol. The water-absorbent copolymer absorbs inks, and the water-resistant graft copolymer makes the receptive layer resistant to discoloration, blurring, and gloss or luster irregularities. The water-absorbent graft copolymer comprises a graft copolymer produced by grafting a vinyl monomer having a carboxyl group and a monomer having a functional group reacting with the carboxyl group. The water-absorbent copolymer comprises a copolymer of acrylic acid and vinyl alcohol. The water-resistant graft copolymer and the water-absorbent copolymer are added at a ratio in parts by weight ranging from 20/80 to 80/20, preferably, from 30/70 to 70/30.
摘要:
According to one embodiment, a video server includes a plurality of processing modules and a maintenance/management module. The processing modules output an activity log file to the maintenance/management module. The maintenance/management module includes a storing medium and a maintenance/management controller. The controller determines whether the storing medium has a free region for recording the activity log file in the storing medium. The controller deletes an oldest activity log file recorded in the storing medium to form a free region if the storing medium has no free region. The controller writes the activity log file in the formed free region.
