The Dell Inspiron Mini 9 (also called the Inspiron 910), was announced on September 4, 2008, as a netbook set to contend with other low-cost ultra-portables such as the ASUS Eee PC and Acer Aspire One. The Mini 9 was also sold as the Dell Vostro A90 by the Dell Small Business Unit.
"Dynamo Electric Machine" (end view, partly section, U.S. patent 284,110) A dynamo is an electrical generator that creates direct current using a commutator.Dynamos were the first electrical generators capable of delivering power for industry, and the foundation upon which many other later electric-power conversion devices were based, including the electric motor, the alternating-current ...
As an example, a 250 kVA motor–generator operating at 300 ampere of full load current will require 1550 ampere of in-rush current during a re-closure after 5 seconds. This example used a fixed mounted flywheel sized to result in a 1 ⁄ 2 Hz per second slew rate. The motor–generator was a vertical type two-bearing machine with oil-bath ...
Within a block two words are recorded serially on each of the 31 tracks. A full reel of tape can contain 50,000 blocks (37,200,000 words). Data transfer rate is 60,000 digits per second. A DATAmatic 1000 system can attach up to 100 tape units. When the tape is initially written data is recorded only in alternate blocks.
The first-generation Inspiron XPS and Inspiron 9100 (2004) are similar models, and both of them shared the same options in processors (desktop Intel Pentium 4 HT "Prescott" or Intel Pentium 4 Extreme Edition "Gallatin"), RAM (DDR 400 MHz), hard-drives (Ultra-ATA 5400/7200 rpm), wireless cards, LCD screens (at 15.4-inches; WXGA, WSXGA+, WUXGA ...
The generator may have additional sections to modify the basic signal. The 8088 for example, used a 2/3 duty cycle clock, which required the clock generator to incorporate logic to convert the 50/50 duty cycle which is typical of raw oscillators. Other such optional sections include frequency divider or clock multiplier sections. Programmable ...
It is also known as a unipolar generator, acyclic generator, disk dynamo, or Faraday disc. The voltage is typically low, on the order of a few volts in the case of small demonstration models, but large research generators can produce hundreds of volts, and some systems have multiple generators in series to produce an even larger voltage.

Frequency stability of 0.1 percent per hour for analog generators [5] or 500 ppm for a digital generator. Maximum sinewave distortion of about 1% (accuracy of diode shaping network) for analog generators. [6] Arbitrary waveform generators may have distortion less than -55 dB below 50 kHz and less than -40 dB above 50 kHz.
