摘要： A method for manufacturing a mechanical grating device is presented. The device consists of a plurality of parallel-suspended ribbons that are deformed using, for example, an electrostatic force to actuate alternate ribbons. Actuation is a deformation of the ribbon resulting from an applied voltage to affect the height of the ribbons above a substrate. The method for manufacturing a mechanical gating device comprises the steps of: providing a spacer layer on top of a protective layer which covers a substrate; etching a channel entirely through the spacer layer; depositing a sacrificial layer at least as thick as the spacer layer; rendering the deposited sacrificial layer optically coplanar by chemical mechanical polishing; providing a tensile ribbon layer completely covering the area of the channel; providing a conductive layer patterned in the form of a grating; transferring the conductive layer pattern to the ribbon layer and etching entirely through the ribbon layer; and removing entirely the sacrificial layer from the channel.

摘要： A continuous ink jet print head is formed of a silicon substrate that includes integrated circuits formed therein for controlling operation of the print head. An insulating layer or layers overlies the silicon substrate and has a series or an array of nozzle openings or bores formed therein along the length of the substrate and each nozzle opening is formed in a recess in the insulating layer or layers by a material depletion process such as etching. The process of etching defines the nozzle openings at locations where heater elements are formed in the insulating layer or layers during a conventional CMOS processing of the integrated circuits. The print head structure thereby provides for minimal post processing of the print head after the completion of the CMOS processing.

摘要： An inkjet printhead for printing an image on a printing medium is provided that includes a substrate having an interior and a nozzle face, a plurality of nozzles having outlets in the nozzle face, an electronically-operated droplet deflector disposed adjacent to each of the nozzle outlets, and feedthroughs for connecting the droplet deflector to power and image data circuits through the substrate interior. The feedthroughs include bores disposed through the substrate for accommodating conductors connected between the droplet deflectors and power and image data control circuits of the printer. The feedthroughs may take the form of bores either coated or filled with electrically-conductive material. The use of feedthroughs through the printhead substrate avoids the manufacture of an undesirably high density of connectors and conductors on the nozzle face and facilitates the manufacture of smooth and flat nozzle faces which are easily cleaned during the printing operation by wiping mechanisms. The power feedthroughs may be easily manufactured via MEMS bulk micromachining technology at the same time the substrate ink channels are formed.

摘要： A continuous ink jet print head is formed of a silicon substrate that includes integrated circuits formed therein for controlling operation of the print head. An insulating layer or layers overlies the silicon substrate includes conductors at various levels to provide conductive paths for transmitting control signals for controlling the print head. The insulating layer or layers also has a series or an array of nozzle openings or bores formed therein along the length of the substrate to provide a substantially planar surface to facilitate cleaning of the printhead. Each nozzle opening is formed as an elongated bore that extends through the insulating layer or layers to the silicon substrate. A heater element is formed adjacent each nozzle opening and in proximity to the planar surface to provide asymmetric heating of the ink stream as it leaves the nozzle opening.

摘要： An electro-mechanical grating device for diffracting an incident light beam has a base which defines a surface. A spacer layer is provided above the base, said spacer layer defining an upper surface of said spacer layer. A longitudinal channel is formed in said spacer layer. A plurality of spaced apart deformable ribbon elements are disposed parallel to each other and span the channel. The deformable ribbon elements define a ribbon structure which comprises at least one layer of a single material. The ribbon elements and the electro-mechanical grating device are formed so that charge build-up in layers of the electro-mechanical grating device can be avoided during operation of the device.

摘要： A drop-on-demand liquid emission device, such as for example an ink jet printer, includes a member movable through a path for driving liquid from the device, wherein the speed at which the member moves is reduced over the time period that liquid is being expelled. During that time period, a portion of the liquid flows through a passage away from the nozzle orifice. According to a feature of the present invention, a variable flow restrictor increases the resistance to flow through the passage during the time period that liquid is being expelled; thereby tending to compensate for the reduction of the liquid-expulsion force over the time period. The result is a reduction of undesirable satellite droplets following a main drop.
