    摘要： A method of manufacturing a thermal ink jet printhead wherein a reusable mandrel consisting of either a metal pattern on an insulating or semiconductive substrate or an insulating pattern on a metal substrate or metal layer is used in the process of electroforming a plurality of metal substrates used for starting a batch fabrication process. Next, thin film layers of insulating, resistive, and conductive materials are formed on the surfaces of the metal substrates to thereby define heater resistors and lead-in conductors for the plurality of thermal ink jet printheads being formed. Then, a barrier layer such as Vacrel is photodefined on the surface of the thin film insulating, resistive, and conductive layers to thereby define a plurality of ink drop ejection chambers surrounding each of the previously formed heater resistors. Next, a plurality of orifice plates are secured, respectively, to the barrier layers in each of the printheads being formed. Finally, the plurality of metal substrates may be removed from the mandrel, such as by stripping away, without the requirement for substrate dicing, and an appropriate mask on the mandrel may be used to create an ink feed hole in each of the metal substrates. The metal substrates are further provided with a break tab line during the electroforming process which is aligned with break patterns in both the above thin film layers and orifice plates. In this manner, the individual thin film printheads may be easily broken away and separated one from another.

    摘要： An improved ink jet print head structure. The print head includes a cylindrical glass rod having a bore extending along the axis of the rod. A surface is ground on the rod parallel to and near the bore. A metal organic paste is fired on the surface and a piezoelectric driver plate is soldered to the paste. A silicon nozzle plate is bonded to the front of the rod by means of an anodic bonding technique. The head structure may be attached to a charging electrode by means of an insulating support member, resulting in a prealigned and easily replaceable unit. Several alternative embodiments of the head structure and means for attaching the structure to an input line are disclosed.

    摘要： The practice of this disclosure obtains a monolithic structure useful for electrohydrodynamically synchronizing the formation of droplets in a jet stream exiting from a jet nozzle. The monolithic structure is primarily adaptable for ink jet printing. The jet nozzle structure provided by the practice of this disclosure includes a jet nozzle design in a crystalline semiconductor block, e.g., of silicon (Si), germanium (Ge) or gallium arsenide (GaAs), with an electrode structure which is integrally incorporated therewith whereby a variable electric field is established proximate to the orifice of the jet nozzle structure. The electric field electrohydrodynamically perturbs the jet stream emitting from the jet nozzle structure so that formation of drops in the jet stream is controllably achieved, e.g., synchronously when the variable electric field is oscillating with a given periodicity.

    摘要： A thermal inkjet printer is operated in a spray-mode by deliberately firing ink droplets from a printhead while the meniscus of the remaining ink in the printhead is settling down. Generally, the drops will not travel in a direction perpendicular to the printing surface. By calibrating the printhead, one can determine how many drops are needed to be fired within the boundaries of a pixel to achieve any given optical density. Drops may be fired at rates above 50 kHz, and, depending on the ink, above 70 kHz. Ink with a viscosity of 10 centi-Poise or less, and even 2 centi-Poise or less, may be used. When one is printing both text and non-text images on the same surface, a digital representation of an image to be printed is analyzed and divided into non-text image fields and text fields. Each non-text image field is printed on the printing surface by projecting the corresponding ink droplets in the spray-mode. Each text field is printed on the printing surface in a text-mode, in which the firing rate is typically reduced to 5-10 kHz and the corresponding ink droplets are projected substantially perpendicular to the printing surface.

    摘要： In an ink jet printing system, a single nozzle or an array of nozzles are etched in a semiconductor material such as silicon. Each nozzle has polygonal or N-sided entrance and exit apertures of different cross-sectional area. Preferably, the nozzle is in the shape of a truncated pyramid with the entrance and exit apertures being substantially square in cross-section. The corners of the apertures and wall interfaces may be rounded to reduce stress concentrations.

    摘要： An ink fill slot 18 can be precisely manufactured in a substrate 12 utilizing photolithographic techniques with chemical etching. N-type silicon wafers are double-side coated with a dielectric layer 26 comprising a silicon dioxide layer and/or a silicon nitride layer. A photoresist step, mask alignment, and plasma etch treatment precede an anisotropic etch process, which employs an anisotropic etchant for silicon such as KOH or ethylene diamine para-catechol. The anisotropic etch is done from the backside 12b of the wafer to the frontside 12a, and terminates on the dielectric layer on the frontside. The dielectric layer on the frontside creates a flat surface for further photoresist processing of thin film resistors 16.
