A lamp inverter with continuous strike voltage facilitates faster striking of a fluorescent lamp, especially at cold temperatures. A frequency sweep generator sweeps the frequency of the lamp inverter to a striking frequency corresponding to a striking lamp voltage and then maintains the striking frequency until the lamp strikes.

A pre-chamber for use with a spark plug or glow plug, the chamber being secured at an upper end attachable unit associated with an internal combustion cylinder. The pre-chamber is designed to promote faster ionization resulting in more efficient spark to flame ignition (due to voltage buildup being delayed until a generated spark jumps the gap), or beat to flame ignition (due to the introduction temperature of the injected plasma) and, in each instance, results in faster propagation of flame within the compressed cylinder, thereby achieving more efficient and consistent (cycle to cycle) output in combination with lower exhaust temperatures. A plurality of outlet ports are defined, such as perimeter / radially extending fashion, in an outlet end of the pre chamber body and communicate the combusted fuels as a plurality of flame outlets with a remaining volume of atomized fuel within the combustion chamber during a power outlet stroke.

A spark plug provided to ignite fire and generate power for an engine, comprises an outer layer with an inner cavity and a ceramics insulator enclosing a central electrode inside the inner cavity. A gap is located between the ceramics insulator and the housing. The central electrode has a body and a head. One end of the body radically extends and forms a tip. The present invention improves ignition and fuel efficiency, thereby reducing air pollution.

An ignition plug cooling device of a vehicle engine for efficiently cooling the ignition plugs while increasing the freedom in the arrangement of the ignition plugs. A vehicle engine includes a first ignition plug and a second ignition plug for making respective electrodes thereof face a combustion chamber and are mounted on a cylinder head. An air flow passage through which a flow of air passes and a cooling oil chamber through which lubrication oil for the engine passes are formed in the cylinder head. The first ignition plug is arranged in the air flow passage to enable a cooling of the first ignition plug by the flow of air which passes through the air flow passage. The second ignition plug is arranged adjacent to the cooling oil chamber to enable a cooling of an area around the second ignition plug by oil which passes through the cooling oil chamber.

A method to solve such a problem that plasma will not ignite in restarting operation of a processing container that has not been operated with the inside kept drawn to vacuum. Gas containing oxygen is passed in a processing container 21, and ultraviolet light is irradiated to the gas while gas inside the processing container 21 is being discharged. After that, a remote plasma source 26 is driven to ignite plasma.
