Abstract:
PURPOSE:To obtain an ink jet recording head having reliability by easy steps by so forming a conductive film as to cover many grooves of a board, removing the film on the board, then forming an insulating film made of paraxylene on the board, and irradiating the surface with a UV ray to integrally adhere the upper board to the board. CONSTITUTION:A conductive film 3 is so formed on a board 1 as to cover grooves 2 on the board 1 provided with many grooves 2 for forming ink channels. Then, after the film 3 on the board 1 is removed, independent electrodes 4 are formed on inner walls of the grooves 2. Thereafter, an insulating film 5 made of paraxylene for protecting the electrodes 4 is so vapor- deposited from above the board 1 as to cover the electrodes 4, and then irradiated with a UV ray. After the film 4 is converted from hydrophobic to hydrophilic by the irradiation, an upper board 6 is integrally adhered to the board 1, thereby completing an ink jet recording head having a plurality of ink channels 7 therein.
Abstract:
PURPOSE:To obtain a reversible recording material easy to fix and easy to release a fixed state by providing a thermal layer reversibly changing in transparency in dependence on temp. to one surface of a base material and providing a self-adhesive layer to the other surface of the base material. CONSTITUTION:A predetermined amount of a resin matrix such as a polyvinyl chloride resin, a vinyl chloride/vinyl acetate copolymer resin or a polyester resin is dissolved in an org. solvent and a predetermined amount of an org. low-molecular substance with an m.p. of 30-200 deg.C such as alkanol or alkane diol is mixed with the resin solution to prepare thermal ink. Self-adhesive ink is prepared by dissolving a resin having self-adhesiveness such as an acrylic resin, a urethane resin or a vinyl resin in an org. solvent. The thermal ink is applied to the surface of a base material 1 such as paper or a resin film and dried to form a thermal layer. Next the self-adhesive ink is applied to the rear of the base material 1 and dried to form a self-adhesive layer to form a reversible recording medium 4.

CONSTITUTION:A synthetic resin adhesive such as epoxy or polyimide is used and a solid adhesive 9 is molded to a specified shape and placed on an oscillator plate. Next, a nozzle plate is positioned on the solid adhesive, then this whole form is thermally bonded together under pressure.

PURPOSE:To prevent the breakage of a small-diameter wire, to obtain a high printing quality, and to contrive a long-life printer, by a method wherein an impact printer ink ribbon comprises a synthetic resin base cloth having the thread count of an original yarn in the warp direction equal to that in the woof direction. CONSTITUTION:In an impact printer ink ribbon holding an ink in a synthetic resin base cloth, the synthetic resin base cloth is made of nylon and obtained by weaving an original yarn of 40 denier in the warp and woof directions. The number of filaments composing the yarn is 34 in the warp and fill directions, and a thread count is 170 to 185 in the warp direction and 150 to 170 in the woof direction. In this manner, the breakage of a small-diameter wire can be prevented, and a high printing quality can be obtained.
Abstract:
PURPOSE:To obtain an endless ink ribbon which is not broken at the fused section for long-time printing by inserting epoxy resin film between both ends of a ribbon on the fused section. CONSTITUTION:Ink ribbon used as an endless ink ribbon contains ink in the synthetic resin fiber and both ends of the ink ribbon hold epoxy resin film which is cured by ultrasound deposition. Consequently, the life of the fused section can be prolonged and the endless ribbon which enables improvement of print quality in the fused section is obtained.
Abstract:
PURPOSE:To obtain the title ink which can be used in printing with a bubble jet printer to give a clear printed image free from blurring, by incorporating xylenol into an ink. CONSTITUTION:This ink is solid at ordinary temperature and contains xylenol. The xylenol content is preferably 70-99% based on the total weight of the ink. This ink can be used in printing with a bubble jet printer to give a clear print free from blurring.
Abstract:
PURPOSE:To contrive prevention of breakage of small diameter wires and enhancement of printing quality, by using nylon as a blank material for a synthetic resin base fabric, specifying the fineness of the raw yarn, the number of filaments and the count, and incorporating specified amounts of carbon black and nigrosine and oleic acid into an ink. CONSTITUTION:An ink ribbon for an impact printer, comprising an ink supported on a synthetic resin base fabric, uses nylon as a blank material for the base fabric, and has a fabric structure in which the fineness of the raw yarn is 30 deniers for both the warp and the weft, the number of filaments constituting the yarns is 26 for both the warp and the weft, and the count of the warp is 170-185 whereas the count of the weft is 105-120. The ink comprises 1-6wt.% of carbon black, 15-25wt.% of nigrosine, and 60-74wt.% of oleic acid. The ink comprises an oil, a dispersant or the like, if required, in addition to carbon black, nigrosine and oleic acid. The nylon used as the black material may be either nylon 66 or nylon 6. With this ink ribbon, breakage of small diameter wires can be prevented, high printing quality can be obtained, and the useful life of the printer can be prolonged.
Abstract:
PURPOSE:To prevent printing quality from being deteriorated and prevent a multistrike ink ribbon from being broken, by providing a back coat layer on the side opposite to an ink layer of the ink ribbon. CONSTITUTION:An ink ribbon for use on an impact printer comprises a synthetic resin film base 1, an adhesive provided as required on the base 1, and an ink layer 2 comprising at least a resin, an oil poorly compatible with the resin, and a colored substance. A back coat layer 7 comprising at least a synthetic resin and a fluororesin powder is provided on the side opposite to the ink layer 7. By this, it is possible to suppress abrasion of type members in the impact printer, prevent printing quality from being deteriorated and prevent the multistrike ink ribbon from being broken.
Abstract:
PROBLEM TO BE SOLVED: To solve the following problems: in the case of forming a liquid introducing region in a straight part by anisotropic etching, a nozzle shape becomes a projecting shape with combination of a column constituting the straight part and a columnar recessed portion constituting the liquid introducing region, if using a stepped shape between the liquid introducing region and the straight part, when a driving frequency of a pressure generation chamber is increased in order to deal with irrregularities in liquid meniscus in a liquid droplet ejection device, irregularities occur in liquid ejection, then, it becomes difficult to achieve high-speed driving, consequently, a plotting speed is reduced. SOLUTION: The recessed portion (a) functioning as a nozzle is formed by anisotropic-etching through the masking use of a photoresist layer 211 as a first mask, and a bowl-like recessed portion (b) is formed by isotropic wet etching through the masking use of a photoresist layer 212 as a second mask. As compared with the conventional manner where the columnar recessed portion is used, the liquid meniscus is stabilized against the vibration resulting from the ejection from the liquid droplet ejection head 115, consequently, the high-speed plotting is achieved.
