    Abstract: PROBLEM TO BE SOLVED: To make a laser fusion hole having a concentric entrance hole without fusion material outside of the diameter of the hole by covering a nozzle plate with a laser fusible thin film and making a hole through the nozzle plate by focusing a laser. SOLUTION: A removable thin protective film 40 is held firmly on the outer surface of a plate 20' trough a peelable adhesive. The film 40 is made of a cleanly fusible substance and adapted to the surface of a nozzle plate. A radiation output is derived from a laser 42 through an projection mask 44 and focused onto the film 40 and the nozzle plate 20'. A mask 44 corresponds to a channel in the front face of a print head and has an arranged opening. Since nozzles formed in the nozzle plate have substantially perfectly balanced holes, no fusion material is present around the hole on the surface of the nozzle plate.

    Abstract: PROBLEM TO BE SOLVED: To facilitate the formation of the electrical connection when an electromechanical transducer is mounted to a metallic diaphragm plate.
    SOLUTION: A droplet injection device has a diaphragm layer 137 provided on a fluid channel layer 131, a blanket dielectric layer provided on the diaphragm layer, and a thin-film circuit 138 which is provided to the blanket dielectric layer and includes a protruding contact point region. The protruding contact point pad is formed higher than the other layer parts. Therefore, a plurality of the electromechanical transducers can easily adhere to each protruding contact point pad.

    Abstract: PROBLEM TO BE SOLVED: To provide a method for forming a feature in a polymeric material. SOLUTION: This feature forming method includes a step for irradiating a polymer layer formed on a substrate sheet with an abrasion laser to form at least one feature on the polymer layer. The polymer layer contains a non- photosensitive material, and the substrate sheet contains a material selected from the group consisting of silicon, quartz, glass, ceramics and a metal. At least one feature has a width (i) of about 2-1,000 μm and a height (ii) of about 0.1-1,000 μm. COPYRIGHT: (C)2003,JPO

    Abstract: PROBLEM TO BE SOLVED: To reduce a resistance of a channel while preventing the channel from being clogged by a foreign substance in a fluid. SOLUTION: There is provided a substantially flat filter to be bonded to a printing head. The filter has a plurality of penetrating pores each having a cross section with a larger length than a width. Spherical particles or nearly spherical particles cannot pass the filter. Also is disclosed a method for fabricating a filter element comprising a step of setting a polymer thin film in an output radiation path of an ablating laser, and a step of controlling a laser output so that a plurality of pores each having a cross section with a length L and a width W smaller in the dimension than the L are formed in the part of the polymer thin film.

    Abstract: PROBLEM TO BE SOLVED: To provide an apparatus and a method for bonding a nozzle plate to a surface of a nozzle of a print head. SOLUTION: A nozzle hole array and a nozzle plate are formed into thin polymer film by laser ablation and carried to a bond station 25. The nozzle plate is adjusted in position by a pin set at a curved face of a holder 38. Both a print head holder 24 and the nozzle plate holder 38 can be adjusted in a vertical direction and a rotational direction to a nozzle array at a surface of a print head 22. This adjustment ensures that the nozzle plate having a bond layer at a bottom face is first in tangential contact with the center of the nozzle array, so that nozzle holes can be correctly agreed with the nozzle array at the surface of the print head 22.

    Abstract: PROBLEM TO BE SOLVED: To permit the discharging of one droplet size selectively among a plurality of droplet sizes with a single ejector by a method wherein a converter for changing applied electric energy into thermal energy and a distributor for defining a heating surface in a flow passage are provided. SOLUTION: Converters 20a-20d are arranged along the periphery of heating surface of a heating element 14 as one series of strips so as to be extended across the heating surface. The converters 20 change an applied voltage into a thermal energy. On the other hand, a distributor 22 distributes heat, formed by the converters 20. In this case, when a voltage and/or a pulse width, applied to the converters 20, becomes big, a large area of necessary nucleus of foam producing temperature exists in the heating surface, formed of the heating element 14, whereby bigger vapor foam is generated. According to this method, one droplet size can be discharged selectively among a plurality of droplet sizes by single ejector.
