Abstract: An ink cartridge includes a residual ink sensing unit having a simple structure of an upper electrode plate and a lower electrode plate to accurately detect a capacitance between the upper and lower electrode plate. Therefore, data of a remaining amount of ink is reliably measured, there is less possibility that an ink bag is damaged when the residual ink sensing unit is installed in the ink bag, and damage to the ink cartridge and defective printing due to unstable supply of ink and the missing of the time for replacing the ink cartridge are prevented.

Abstract: An inkjet image forming apparatus and a method of performing a high resolution printing using multiple passes. In the inkjet image forming apparatus and a method of performing a high resolution printing, it is possible to obtain a resolution that is higher than an actual resolution of a print head by performing a printing operation several times on a printing medium in a multi-pass type printing method while moving the print head along a length direction thereof. As a result, printing quality can be improved by minimizing visibility of missing dots that occur due to failed nozzles.

Abstract: An ink level detecting device also functions as a cover opening sensor, and an ink-jet image forming apparatus having the ink level detecting device functions in the same way. The ink level detecting device detects an ink level in an ink container mounted on an ink container mounting unit, and includes a first electrode disposed on an inner surface of a cover which covers the ink container mounting unit and a second electrode disposed on the ink container. The ink level detecting device detects an opening of the cover as well as an ink level variation by sensing a variation in a capacitance between the first and second electrodes.

Abstract: An ink level detecting apparatus usable with an ink-jet printer includes an ink tank having a bottom, a ceiling, and a sidewall, a shrinkable ink pack is accommodated in the ink tank and having a top surface that moves down evenly as an ink level in the shrinkable ink pack decreases, a fixed electrode installed to an upper portion of the ink tank, and a movable electrode disposed to face the fixed electrode at a predetermined distance from the fixed electrode. The movable electrode moves in a horizontal direction according to a height variation of the top surface of the shrinkable ink pack such that an overlap area between the movable electrode and the fixed electrode varies. Therefore, the ink level is detected from electric capacity variation sensed between the fixed electrode and the movable electrode.

Abstract: A dual channel gas distributor can simultaneously distribute plasma species of an first process gas and a non-plasma second process gas into a process zone of a substrate processing chamber. The gas distributor has a localized plasma box with a first inlet to receive a first process gas, and opposing top and bottom plates that are capable of being electrically biased relative to one another to define a localized plasma zone in which a plasma of the first process gas can be formed. The top plate has a plurality of spaced apart gas spreading holes to spread the first process gas across the localized plasma zone, and the bottom plate has a plurality of first outlets to distribute plasma species of the plasma of the first process gas into the process zone. A plasma isolated gas feed has a second inlet to receive the second process gas and a plurality of second outlets to pass the second process gas into the process zone.

Abstract: A stressed film is formed on a substrate. The substrate is placed in a process zone and a plasma is formed of a process gas provided in the process zone, the process gas having silicon-containing gas and nitrogen-containing gas. A diluent gas such as nitrogen can also be added. The as-deposited stressed material can be exposed to ultraviolet radiation or electron beams to increase the stress value of the deposited material. In addition or in the alternative, a nitrogen plasma treatment can be used to increase the stress value of the material during deposition. Pulsed plasma methods to deposit stressed materials are also described.
