(vi) potential ignition sources (including electrical equipment).

Examples Gasoline (petrol) is a fuel for use in a spark ignition engine.

And one of those competitions, I just won a small, little transistor Philips radio.

Transistor radios and television sets have made their way to the most remote rural areas.

The introduction of the transistor and integrated circuits in the 1960s made electric logs vastly more reliable.

Safety actions are necessarily linked to the type of hazard which exists, e.g., flammable liquids should be stored away from ignition sources.

The development of the germanium transistor in 1948 opened the door to countless applications of solid state electronics.

When the transistor goes into saturation from all inputs being high, charge is stored in the base region.

This is one of many possible ways in which a molecular level diode transistor might be synthesized by organic chemistry.

To design a safer machine with its structure around the engine, the pair wrote to German ignition specialist Robert Bosch for advice on a different electromagnetic system.

The National Ignition Facility, or NIF, is a large laser based inertial confinement fusion (ICF) research device, located at the Lawrence Livermore National Laboratory in Livermore, California.

As this view is sometimes put, the next 20 years will see no breakthrough as revolutionary as the steam engine or the transistor.

The second, co authored primarily with Milton Feng in 2005, announced the creation of a transistor laser that can operate at room temperatures.

Just as applications of electronics have expanded dramatically since the first transistor was invented in 1948, the unique applications of photonics continue to emerge.

This seminal work became the reference text for other scientists working to develop and improve new variants of the transistor and other devices based on semiconductors.

A small number of large scale nuclear fusion systems also exist including the National Ignition Facility in the USA, JET in the UK, and soon the recently started ITER experiment in France.

He and Dr. Milton Feng run a transistor laser research center at the University funded by 6.5 million from the United States Department of Defense through DARPA.

Refined versions of this tube were the basis of all electronic sound systems until the commercial introduction of the first transistor based audio devices in the 1950s.

It is not just about the density of transistors that can be achieved, but about the density of transistors at which the cost per transistor is the lowest.

But our friends who are condensed matter physicists managed to come up, some 50 years ago, with a very nice device, shown under that bell jar, which is a transistor.

The US Department of Defense was the only customer for integrated circuits in 1962, but by the end of the decade consumers were buying transistor radios and pocket calculators in droves.

As shown in the diagram, the emitter current, I E, is the total transistor current, which is the sum of the other terminal currents, (i.e., I E I B I C).

It is called so because the logic gating function (e.g., AND) is performed by a diode network and the amplifying function is performed by a transistor (in contrast with RTL and TTL).

Japanese companies have been responsible for a number of important innovations, including having pioneered the transistor radio and the Walkman (Sony), the first mass produced laptops (Toshiba), the VHS recorder (JVC), and solar cells and LCD screens (Sharp).

But what's happening now is that in 2015, the transistor is going to become so small, that it corresponds to only one electron at a time can flow through that channel, and that corresponds to a single ion channel.

The HP 9100 series was built entirely from discrete transistor logic with no integrated circuits, and was one of the first uses of the CORDIC algorithm for trigonometric computation in a personal computing device, as well as the first calculator based on Reverse Polish Notation (RPN) entry.

Yes, being better connected with each other, through Facebook or Twitter, is valuable. But how can we compare these innovations with those like the laser, the transistor, the Turing machine, and the mapping of the human genome, each of which has led to a flood of transformative products?
