Toner Cartridges

The actual particle size of toner comes about 12 micrometers. When image resolution was enhanced to 600 dots per inch, any how, the particle dimension was condensed to 8 micrometers. Further reductions in size would be essential for developments in resolution. Toner cartridges manufacturers preserve an excellence control standard for actual particle size in order to create a powder appropriate for use in their printers; the actual particle size in the product is not really allowed to vary too much from the essential dimension.

Toner has usually been made by compounding the ingredients and making a slab that was broken or palletized and then turned it into a fine dry toner powder with a controlled actual particle size variety by air jet milling. This procedure resulted in toner cartridge a granule that, if looked via microscope, displayed different sizes and jagged shapes. To get a best print, some ink/toner companies … Read the rest

Ultrasonic Welding

The ultrasonic welding process offers many advantages over other welding techniques and is most commonly used in manufacturing wire harnesses, electronic components, and appliances. Ultrasonic welding is used when multiple layers of foil need to be welded onto a terminal or welded together with different combination of metals such as copper, aluminum, lithium, and nickel.

Ultrasonic welding uses a “low power friction” welding process in which little heat is generated and better control can be applied. The basic idea is to scrub work pieces across each other while clamped under pressure to create a bond. Work pieces are placed on an anvil that is knurled with fine ridges that bite into the material, holding it in place during the weld process. The ultrasonic tool is then lowered onto the pieces, clamping them under pressure and creating the needed scrubbing action. This tool vibrates at a frequency of twenty kilohertz for … Read the rest

Hidden Hindrance to Virtualization Performance

More specifically, it is the creation of one or more virtual instances of a “guest” operating system on top of a “host” operating system, or in some cases directly on top of a specialized software layer. It allows numerous virtual machines, either standard PCs or servers, to operate and appear as independent machines when in fact they’re operating off of a single hardware platform.

Many software providers from large to small are in the race to offer virtualization solutions, and many enterprises are taking advantage. While this futuristic technology certainly offers many benefits, it has one critical challenge to its overall performance–disk file fragmentation.

File fragmentation–the splitting of files into pieces (fragments) in order to better utilize disk space–is a performance challenge in non-virtual environments, and has been for many years. But virtualization brings with it even more critical fragmentation issues, requiring solutions like never before.

Measuring Signals

The signals are displayed first in a pattern then the spectrum analyzer plots the amplitudes on the vertical axis and the frequencies on the horizontal axis. The vertical axis represents the strength of the signal while the horizontal axis represents the time based frequencies.

The spectrum analyzer is different from an oscilloscope, another device that measures signals. One of the basic differences is that a spectrum analyzer shows the received signal strength against the frequency while an oscilloscope displays received signal strength against time. This makes the spectrum analyzer useful for measuring and studying the amplitude response of a device against a frequency. Measurement output of spectrums is in decibels or dbm while in oscilloscopes, the measurement output is in volts.

Moreover, an oscilloscope is unable to measure very low voltage levels and for that matter it is used mainly for low frequencies and high amplitude measurements only. But in … Read the rest

Remanufactured Ink Cartridges

Remanufactured ink cartridges are generally backed by an exclusive 100% guarantee to ensure your complete satisfaction. Some sellers give remanufactured ink cartridges with a warranty that even covers your machine. In some cases, these remanufactured ink cartridges actually contain more ink than the originals.

Remanufactured ink cartridges are professionally remanufactured inkjet cartridges that have been used once and have been recharged. Each cartridge and its print-head nozzles are thoroughly cleaned and filled with the same type of premium ink, checked for the correct internal pressure after inspection for any possible cover leakage and finally ran through a print test. Such a cartridge that passes these rigid quality check standards can only be termed “remanufactured.” It is generally seen that most remanufactured cartridges are 100% guaranteed.

Remanufactured ink cartridges are a practical alternative to branded ink cartridge. Since these remanufactured ink cartridges undergo stringent testing, they are an excellent alternative to … Read the rest

Industrial Electronic Repairs

Generally, a thin line of demarcation is present between what is called industrial electronic repairs and domestic electronic repairs; this is because of the vast variety of industrial equipment. A number of industrial manufacturers and other kinds of businesses generally employ a number of electronic machines necessarily required to keep their businesses running efficiently. Some such machines and equipment for that purpose are printed circuit boards, tool controls and electronic control for temperature, timers and computers.

One very important aspect of industrial electronic repairs is to diagnose the fault in order to assess the status of the faulty electronic apparatus, and thus to identify the components necessarily needed to bring it back to working order. The precise way of repairing the electronic equipment varies with the company and its business strategy. One can find many online companies undertaking such repairs. Some of those companies may be outsourcing their services to … Read the rest

Turning Up the Heat

For instance, atmospheric temperatures determine weather. This in turn will determine what we will wear and what activities we can and cannot do. On a more macro level, temperature is a key component to maintaining the order and flow of certain manufacturing processes. So you see, from cooking to complicated industrialized processes, the importance that the nature of temperature plays is very important.

The role of temperature in the manufacturing business is entrenched in the fact that as a physical property, temperature is a key factor that needs to be considered in almost all fields of science.

As we know, science is behind all processing and manufacturing processes in industries. Because of this fact, all special manufacturing processes entail the proper temperature calibration. Each sub process in any manufacturing system will mostly likely need temperature calibration, although it is probably most important in processes that involve chemical reactions.

Electronic Signature

There are a lot of companies which are implementing the use of electronic signs in order to reduce their operational costs. This can also make the process automatic and speed up its processing. In addition, this will address directly on the legal compliance and will restrict liability. What’s more is that the entire process is productive without going through a lot of troubles.

For eleven years now, electronic signs has become enforceable legally making it legally binding similar to a contract that is paper-based. For that matter, it has been given legal significance that will allow companies to comply with the regulations across the world. Furthermore, the use of electronic sign has effects in the environment. There is reduction in the use of oil and carbon emissions.

Even if signatures made by hand and electronically are considered to be legally binding, it is the electronic signature that has the capability … Read the rest

Technology Time Sharing

These computers can also be used to track down criminals, by scanning the Internet or databases. These computers can be used for doing genetic manipulation research to prevent disease and problems in the human body. Unfortunately, we do not have enough of these supercomputers yet and therefore different groups must share the technology.

One problem we have with technology Time-sharing for supercomputers is that there are politics involved in the allocating of resources. A cure for cancer is indeed a very important allocation of such resources, but so is an approaching hurricane at the same time or perhaps we are trying to track sneaky bad guys or international terrorists.

You can see how the politics of allocating supercomputer resources can be very important and perhaps you can also see the problems involved. In fact there are so many uses for number crunching such as a NASA space program or figuring … Read the rest
