摘要： A multi-color level inkjet head chip structure includes a pre-mixing space. The pre-mixing space communicates with different ink storage spaces through a plurality of providing elements, then the volume of different colored inks is controlled by the ink providing elements to be injected into the pre-mixing space. The desired color level ink is created in the pre-mixing space in advance. Finally, the desired color level pre-mixed ink is ejected onto the recording media (such as paper or other similar material) through an inkjet printing driver at the pre-mixing space. Therefore, the desired color level can be produced by only one inkjet printing at any printing area, which will be extremely beneficial for increasing the speed of inkjet printing.

摘要： A common print head module that can accommodate either a single-color or multi-color inkjet print head comprises an ink cartridge having an ink output, and an inkjet chip arranged over the ink output. The ink cartridge internally includes ink channels that terminate through a surface of the ink output, wherein two adjacent ink channels are spaced apart by a channel wall. The channel wall has a top surface lower than the surface of the ink output where the ink channels terminate. The ink channels communicate with ink slots of the inkjet chip. When accommodating a single-color print head, the ink flows out through the ink channels over the channel wall. When accommodating a multi-color print head, the ink slots of the inkjet chip have slot walls that are sealed with the channel walls such that inks of different colors can be separately ejected through the ink slots.

摘要： The ink cartridge of the present invention uses a directional fibrous collection enclosed within a bushing to temporally retain the ink therein, wherein at least one controlled capillary portion is provided. The controlled capillary portion can be formed by the bushing or by a predetermined shape located in the cartridge. The capillary forces of the controlled capillary portion are stronger than the one of other portion of the directional fibrous collection. The flow rate of the ink can be precisely controlled by the directional fibrous collection, and the controlled capillary portion can efficiently drain out the ink to the printhead and there is no bubble left therein.

摘要： A driver transistor structure of an inkjet print head chip and the method for making the same. Having several body contacts distributed all over the source of an active region of a large area MOSFET (Metal Oxide Semiconductor Field Effect Transistor), an equivalent RB from the MOSFET channel to the body contact is greatly diminished as the distance between them is reduced, thereby preventing the occurrence of a secondary breakdown. Since the body contact is installed inside the active region without defining in advance a body contact region and making the body contact in the field oxide layer outside the active region, about 20% of the driver transistor structure can be saved to lower the average manufacturing cost of each chip.

摘要： ZSM-5 crystallites are produced with very low levels of blocking tetrapropyl ammonium ions (Q). The reaction mixture contains sources of silica, soda, alumina and trace amounts of Q ions as nucleation agents. Because the crystallites as synthesized from the aqueous medium exhibit only a very small fraction of blocking cations, there is always a diffusion path for the hydrated sodium ions to be exchanged without the need of prior removal of the blocking cations by calcination or otherwise. The small size crystallites can be exchanged, blended with other materials, and formed into catalyst particles. The silica to alumina ratio can be varied and when no aluminum is added, silicalite may be formed. The systhesis can be done in 24 hours or less.
