Microelectromechanical systems (MEMS) have played an increasingly important
role in sensor and actuator applications. And its key contribution is that it has enabled
the integration of multi-components (i.e., electronics, mechanics, fluidics and etc) on a
single chip and their integration has positive effects upon performance, reliability and
cost. Compared to conventional electrostatic, thermal or magnetic actuating schemes,
piezoelectric MEMS inkjet has the advantages of lower power consumption, lower
voltage operation and relatively larger driving force....
Chọn máy in cho văn phòng nhỏ
Hiện nay, các văn phòng nhỏ có rất nhiều lựa chọn máy in và phổ biến nhất là ba loại: máy in màu (inkjet và laser), máy in đơn sắc (laser) và máy in đa năng. Dưới đây là một số kinh nghiệm chọn mua và 4 gợi ý máy in tốt nhất.
Một máy in tốt cho các doanh nghiệp nhỏ và các phòng làm việc tại gia đình phải có tốc độ in nhanh và cho bản in đẹp bất kể là in trên giấy thường hay giấy đặc biệt. Những model cao...
Tiết kiệm mực in phun bằng cách nào?
Khi cần trang bị một máy in bạn thường chọn dòng máy in phun (inkjet) bởi vì giá của chúng thấp hơn khá nhiều so với máy in laser. Tuy nhiên, máy in phun rất mau hết mực, hơn thế nữa chi phí thay mới một hộp mực phun có khi xấp xỉ giá của một máy in phun mới. Một vài thủ thuật
nhỏ sau đây sẽ giúp bạn tiết kiệm mực in và bảo quản máy in tốt hơn.
Resolution can be as high as 400 X 800 dpi, with gray scales ranging from 16-128 values. These are medium- to high-throughput devices, producing complex images in about a minute. On-board computing facilities, such as RISC processors and fast hard disk storage mechanisms, contribute to rapid drawing and processing speeds. Expansion slots accommodate interface cards for LANs or parallel ports. InkJet Plotter. InkJet plotters and printers fire tiny ink droplets at paper or a similar medium from minute nozzles in the printing head. H...
The use of fluid microdrops in engineering and experimental science goes back
over a century to the study and use of spray generated aerosols, and the use of
aerosol produced microdrops to confirm the predictions of fluid mechanics, atomic
theory and chemistry. The ability to generate fluid microdrops with a predetermined
size, on demand, with precisely controlled trajectories is a more recent invention
dating back only a few decades. Its primary commercial and industrial use today is
in the field of inkjet image printing....
This dissertation will outline solution processable materials and fabrication techniques to
manufacture flexible electronic devices from them. Conductive ink formulations and
inkjet printing of gold and silver on plastic substrates were examined. Line patterning and
mask printing methods were also investigated as a means of selective metal deposition on
various flexible substrate materials. These solution-based manufacturing methods
provided deposition of silver, gold and copper with a controlled spatial resolution and a
very high electrical conductivity.
The ENERGY STAR Office Equipment program distinguishes “digital copier-based MFDs,” which are
covered by their MFD program, from printer- and fax-based MFDs, which are covered by their printer
program. In this study, we identify any multi-function device as an MFD, and distinguish between them on
the basis of imaging technology (inkjet or laser), which we think is most relevant to power consumption.
Many units of office equipment that we identified in the field as copiers, fax machines,...
The 2003 PM rate of 60% for laser printers is similar to the 2000 rate of 61% for “high end color” printers.
In 2000 some inkjet and wide-format printers were in low power, but in 2003 we found none.
The 2000 study did not report on thermal or solid ink printers, probably because few or none were found.
Solid ink is not a widespread printer technology; in 2003 we found four, all in the same building. Of 41
thermal printers in our 2003 sample, only 15%...
3D printers are the fastest growing type of personal manufacturing machine, and
perhaps the best publicized by the popular press. 3D printers use as an additive
process, meaning they make objects by systematically depositing a chosen raw
material in layers. Somewhat similar in concept to that of an inkjet printer that
orchestrates different colored print cartridges to form an image onto paper, the most
common household 3D printing process involves a “print head” that works with any
material that can be extruded, or squirted through a nozzle.
