  2. Orbit insertion - Wikipedia

    en.wikipedia.org/wiki/Orbit_insertion

    An orbit insertion maneuver involves either deceleration from a speed in excess of the respective body's escape velocity, or acceleration to it from a lower speed. When the result is a transfer orbit, e.g. a descent orbit insertion, the maneuver is an orbit injection.

  3. Low-level injection - Wikipedia

    en.wikipedia.org/wiki/Low-level_injection

    Low-level injection conditions for a p–n junction, in physics and electronics, refers to the state where the number of minority carriers generated is small compared to the majority carriers of the material. The semiconductor's majority-carrier concentration will remain (relatively) unchanged, while the minority-carrier concentration sees a ...

  4. Current injection technique - Wikipedia

    en.wikipedia.org/wiki/Current_injection_technique

    In summary, current injection technique makes it possible to use devices with low forward voltage drop for high frequency applications. This also imply cheaper cost of devices as less processing steps are required during the manufacturing stages where the need of carrier lifetime control techniques are reduced.

  5. Ion implantation - Wikipedia

    en.wikipedia.org/wiki/Ion_implantation

    Ion implantation setup with mass separator. Ion implantation equipment typically consists of an ion source, where ions of the desired element are produced, an accelerator, where the ions are electrostatically accelerated to a high energy or using radiofrequency, and a target chamber, where the ions impinge on a target, which is the material to be implanted.

  6. Dead centre (engineering) - Wikipedia

    en.wikipedia.org/wiki/Dead_centre_(engineering)

    In a reciprocating engine, top dead centre of piston #1 is the point from which ignition system measurements are made and the firing order is determined. For example, ignition timing is normally specified as degrees of crankshaft rotation before top dead centre (BTDC). [2]

  7. Extra element theorem - Wikipedia

    en.wikipedia.org/wiki/Extra_element_theorem

    Z d (s) is the single-injection driving point impedance "seen" by the extra element. Z n (s) is the double-null-injection driving point impedance "seen" by the extra element. The extra element theorem incidentally proves that any electric circuit transfer function can be expressed as no more than a bilinear function of any particular circuit ...

  8. Proton Synchrotron Booster - Wikipedia

    en.wikipedia.org/wiki/Proton_Synchrotron_Booster

    A stripping foil at the PSB injection point will strip the electrons off the hydrogen anions, thus creating protons that are accumulated as beam bunches in the four PSB rings. These proton bunches are then recombined at the exit of the PSB and further transferred down the CERN injector chain.

  9. Stratified charge engine - Wikipedia

    en.wikipedia.org/wiki/Stratified_charge_engine

    During the injection process the fuel gets evaporated, cooling the cylinder chamber; Cooling effect of the pressurized fuel allows for use of a lower octane fuel leading to a cost savings for the end user; Higher compression ratios, which translates into more power; Increased fuel combustion efficiency; Higher power during pick-up of vehicle
