    Abstract: PROBLEM TO BE SOLVED: To provide a method of assembling a print head having an electrical interconnect layer that is manufactured more easily than conventional assemblies to increase the jet density of a piezoelectric ink jet print head.SOLUTION: A method of forming an ink jet print head can include a step of attaching multiple piezoelectric elements 20 to a diaphragm 36, a step of dispensing an interstitial layer 50 over the diaphragm, a step of electrically coupling multiple conductive elements 62 to the multiple piezoelectric elements, and a step of curing the interstitial layer. Multiple electrically isolated conductive particles 54 in the interstitial layer electrically couple the multiple conductive elements to the multiple piezoelectric elements. The conductive particles can be evenly distributed throughout the whole of a dielectric of the interstitial layer or can be localized to the top surface of each piezoelectric element and interposed between the multiple piezoelectric elements and the multiple conductive elements. The conductive elements can be part of a flex circuit manifold printed circuit board 60.

    Abstract: PROBLEM TO BE SOLVED: To provide a suitable heater structure for ink jet print head. SOLUTION: A segmented heater structure discharging a fluid onto a medium has heater segments. The area of each heater segment in the heater structure and the power consumption level thereof are selected to discharge fluid droplets of different dimensions based on the pulse voltage and/or the pulse width being used. As the pulse voltage and/or the pulse width being applied to a specified channel increase, a larger number of heating segments in that discharge channel generate bubbles thus producing a larger droplet. Consequently, the volume and the spot size of a discharged fluid droplet can be increased as the pulse voltage and/or the pulse width increase.

    Abstract: PROBLEM TO BE SOLVED: To avoid overheating (causing deterioration of mechanic and electrical properties of a brush) a commutator at laser beam cutting. SOLUTION: This electrical part (commutator brush) 114 has one end to electrically contact at least another part (the electrode of a donor roll). The electrical part 114 has a support 118 and a plurality of conductive fibers 116, having sections extended outward from at least the support, so as to form a brush structure. The free end of the brush is constituted to contact other parts. A laser beam cuts the free end so as to minimize heating of the fiber in cutting. This kind of brush can be used as the commutator brush for scavengeless developer of an electrophotographic printer.

    Abstract: PROBLEM TO BE SOLVED: To provide a high strength filter in which handling and processing step can be carried out without causing any damage while preventing a mixed substance from entering into a channel. SOLUTION: A filter 14 employs a substance which can be fused by laser and removed and the filter 14 is bonded to the ink inlet side of the basic body while being aligned. A thin polymer film is fused and removed while penetrating a mask or a screen and a fine array of small holes is provided in an ink injecting region. The film is laminated to a channel base body to form a filter 14 covering one or more than one ink inlet 25. A substrate is diced therefrom and individual die print head modules, each comprising a filter 14 having one or more than one ink inlet 25, are formed.
