A toner dispensing system and a method for controlling the same. A toner dispensing amount is determined using a pixel dispensing time related to a pixel count adjusted according to the ratio of a transition count to a pixel count per page, a &#x394; automatic concentration control dispensing time relating to the difference between the toner concentration of a developer material and target concentration, and a dispensing rate corresponding to a print job length. The determined amount of toner is dispensed into a developer housing. This method can maintain a toner concentration in order to obtain an accurate image density. A remaining toner ratio (%) determined from a total dispensing time, a dispensing rate, and a toner capacity can also be displayed so that the user can monitor the remaining amount of toner, the used amount of toner, etc., during the life of the toner cartridge.

A process for fabricating a vertical spiral inductor within a multichip module package is disclosed. The process consists of depositing a pattern of bottom lines by electroplating copper on a substrate and then depositing an insulation pattern. Next, depositing a pattern of permeable material to form a core and then depositing polyimide to define vias and permeable core insulation. The vias are filled by electroplating copper. The vertical spiral inductor is formed and defined by next depositing a pattern of top metal (e.g. copper) lines by electroplating wherein the top metal lines are staggered with respect to the bottom metal lines. Lastly a top protective layer is deposited. The core is made from a permeable or non-permeable material.

An acoustic ink printing print head utilizing metal alloyis disclosed. Additionally, a process for incorporating the metal alloy(alloy with approximately 42% nickel and 58% iron) to build the liquid level control/aperture plate defining an AIP print head is disclosed. The process consists of fabricating a channel plate and an aperture plate from the metal alloyand bonding the two structures together thereby defining the liquid level control/aperture plate.

The invention is directed to a fabrication method of copper interconnects using dual damascene processing. Using silicon to provide an active surface, palladium can be selectively deposited on silicon by an immersion plating technique. After palladium deposition (about 1000 &angst; thick), either a layer of cobalt phosphorus or alloy cobalt/nickel phosphorus or nickel phosphorus is deposited on the palladium layer using an electroless plating technique. This cobalt phosphorus, cobalt/nickel phosphorus alloy, or nickel phosphorus layer serves as a copper diffusion barrier. The via and trenches are filled with copper by an electroless copper plating method and CMP is used to remove the excess copper and planarize-/-polish the copper/dielectric surface.

A method for estimation of toner usage in digital xerographic process is disclosed. The method calculates a ratio of transition count/pixel count using a pixel transition count and a pixel count for a printed image and provides an estimate of toner consumption based on the ratio of transition count/pixel count.

Estimation of toner usage

Low acoustic solid wave attenuation structures are formed with an electroformed nickel mold, and are incorporated within acoustic ink emitters, between the focusing lens and surface of an ink layer. The structures have characteristics of low attenuation of acoustic waves to increase the efficiency of acoustic wave transmission within the acoustic ink emitter. Using the described structures, acoustic ink printers can accurately emit materials having high viscosity, including hot melt inks.
