The opening action is obtained when a capacitor, charged to high voltage, is suddenly discharged through the foil.

Furthermore, the chromatic aberrations depend on the chosen high voltage.

In general, a high anode voltage reduces chromatic aberrations and thus increases the obtainable resolution.

It has been stated that settled cathodoluminescent phosphor screens may have a limiting resolution of 60 Af at high voltage values of approximately 20 Aj.

A high voltage is applied across the anode and cathode, resulting in an ionization of the fill gas.

A pulsed high voltage source ( typically 1-2 kV ) is generated and applied to the specimen, with pulse repetition rates in the hundreds of kilohertz range.

Field evaporation is an effect that can occur when an atom bonded at the surface of a material is in the presence of a sufficiently high and appropriately directed electric field, where the electric field is the differential of electric potential ( voltage ) with respect to distance.

* A high voltage system to raise the sample voltage.

Nearly all modern CPUs represent numbers in binary form, with each digit being represented by some two-valued physical quantity such as a " high " or " low " voltage.

Electrical applications for mail include RF leakage testing and being worn as a faraday cage suit by tesla coil enthusiasts and high voltage electrical workers.

B is a high voltage power supply to energize the anode P. Shadow mask M is connected to the cathode potential and its image is seen on the phosphor as a non-glowing area.

The voltage applied between the electrodes accelerates these low mass particles to high velocities.

After the 1690 invention of the vacuum pump by Otto von Guericke, physicists began to experiment with passing high voltage electricity through rarefied air.

The explanation of these effects was that the high voltage accelerated electrically charged atoms ( ions ) naturally present in the air of the tube.

With no obstructions, these low mass particles were accelerated to high velocities by the voltage between the electrodes.

However, a tall building brings a lot of difficulties to structural and building services design, for example, excessive system static pressure for water systems, high line voltage drop and long distance of vertical transportation.

For example, diodes are used to regulate voltage ( Zener diodes ), to protect circuits from high voltage surges ( avalanche diodes ), to electronically tune radio and TV receivers ( varactor diodes ), to generate radio frequency oscillations ( tunnel diodes, Gunn diodes, IMPATT diodes ), and to produce light ( light emitting diodes ).

Before the development of silicon power rectifier diodes, cuprous oxide and later selenium was used ; its low efficiency gave it a much higher forward voltage drop ( typically 1. 4 to 1. 7 V per " cell ", with multiple cells stacked to increase the peak inverse voltage rating in high voltage rectifiers ), and required a large heat sink ( often an extension of the diode ’ s metal substrate ), much larger than a silicon diode of the same current ratings would require.

These include transformers, electric generators, electric motors, high voltage engineering and power electronics.

Central power stations became economically practical with the development of alternating current power transmission, using power transformers to transmit power at high voltage and with low loss.

The voltage of a large lightning cloud may be as high as 100 MV and have discharge energies as great as 250 kWh.

It is nothing you can put your fingers on but the air suddenly fills with a high charge of electricity.

As it is, they consider that the North is now reaping the fruits of excess egalitarianism, that in spite of its high standard of living the `` American way '' has been proved inferior to the English and Scandinavian ways, although they disapprove of the socialistic features of the latter.

It is a quiet but impressive room -- 140 feet long, thirty-nine feet wide, twenty-one feet high.

from downstream, where the water level is much lower, it is a high, elaborately facaded pavilion.

Unruly hair goes straight up from his forehead, standing so high that the top falls gently over, as if to show that it really is hair and not bristle.

The artist, unlike the philosopher, is not a removed observer aiming at neutral and rarified high levels of abstraction.

The trouble here is that it's almost too easy to take the high moral ground when it doesn't cost you anything.

After how many generations is such wealth ( mounting all the while through the manipulations of high finance ) purified of taint??

It is different with his volume The Swedes And Their Chieftains ( Svenskarna och deras Hovdingar ), a history intended for the general reader and particularly suited for high school students.

No matter how earnest is our quest for guaranteed peace, we must maintain a high degree of military effectiveness at the same time we are engaged in negotiating the issue of arms reduction.

The other is that the charge for cabanas and parasols, though modest from an American point of view, still is a little high for many Athenians.

Master Gorton, having foully abused high and low at Aquidneck is now bewitching and bemaddening poor Providence, both with his unclean and foul censures of all the ministers of this country ( for which myself have in Christ's name withstood him ), and also denying all visible and external ordinances in depth of Familism: almost all suck in his poison, as at first they did at Aquidneck.

Milton's name being fourth is neither too high nor too low to be assigned to the arbitrary action of vice-chancellor, proctor, master, or other mighty hand.

The NATO Council is available as an executive agency, the Standing Group as a high military authority.

Around that statue in the green park where children play and lovers walk in twos and there is a glowing view of the whole city, in that park are the rows of marble busts of Garibaldi's fallen men, the ones who one day rushed out of the Porta San Pancrazio and, under fire all the way, up the long, straight narrow lane to take, then lose the high ground of the Villa Doria Pamphili.

the Army, Navy and Air Force, among others, may question Secretary Freeman's claim that the high estate of United States agriculture is the `` strongest deterrent '' to the spread of communism.

He is basing his guess on new government statistics that show business has broadened its stride -- a new record high in personal income, an increase in housing starts, a spurt in retail sales and a gain in orders for durable goods.

It is low when the thyroid is overactive and high when the gland is sluggish.

It is not in business for the purpose of absorbing increased municipal costs no matter how high a purpose that may be ''.

It has already been reported in your newspapers that the East Greenwich School Committee is considering additions to at least one elementary school and to the high school to insure future accommodations for a school population that we know will increase.
