first----->he invented the first electronic video camera tube.

second--->from that he invented the first electronic television

third----->he invented the fusor device. it is one of nuclear fusion device.

fourth---->he contributed in the making of electron microscope

He worked in many fields, one of them was controlled nuclear fusion for which he invented a device called the "Farnsworth fusor".

Yes, besides inventing the television, Philo T. Farnsworth also developed the Farnsworth-Hirsch Fusor, a device for nuclear fusion research. Additionally, he held over 300 patents for various inventions in fields such as television, radio, and radar.

El error 59.30 es un problema con respecto al motor de fusor serir # RH7 16-17 el cual es facil de solucionar con el cambio del motor y aplicando un paso de calibracion para reconiser el nuevo motor

Almost all modern nuclear explosive devices use some of each. The early atomic bombs used only fission. All hydrogen bombs use both fission and fusion.

Some things you might want to look up are: boosted fission bomb, external electrical fusor neutron source, the plutonium "fission sparkplug" used in each stage of a hydrogen bomb, depleted uranium hydrogen bomb tamper can provide up to 90% of the total yield through fast fission.
