摘要:
A system and method are provided to power a plurality of magnetrons devices (30, 40). The system may include a power supply device (DC) to power a first magnetron device, a second magnetron device and a third magnetron device (100, 200, 300). A control device apportions an amount of current to each of the second and third magnetron devices.
摘要:
This invention relates to a tubular apparatus for UV curing coatings on a continuous filament (8) in which concentric tubes (12, 14) are provided and through which the filament passes after being coated for curing the coating, with the apparatus having the first inner tube (12) which passes the UV light through the tube to cure the filament passing therethrough, and a second concentric tube (14) superposed over the first tube and spaced therefrom which reflects IR light and passes UV light to prevent burning and destroying the coating on the filament as it passes through the first tube.

An ultraviolet (UV) oven (2) comprises a compact longitudinal elliptical reflector (4) with first and second focal lines. A longitudinal small-diameter bulb (6) is disposed along the first focal line that generates short wavelength UV, infrared (IR), and visible radiation as well as heat to cure the coating on magnet wires (12) or wire-like elements passed through the other focal line. The reflector's inside surface is coated with material to enhance the reflectivity.
摘要:
A high pressure lamp bulb adapted to simultaneously emit distinct emission spectra of a desired wavelength, the lamp bulb comprising an envelope for containing a fill material under pressure and a fill material, the fill material including a material capable of forming at least two dissimilar excimer species in an amount to provide a total fill pressure no less than about 750 Torr at room temperature.

Electrodeless lamp includes an envelope (6) containing a fill and a substance for facilitating the starting of the lamp. An outer tube (18) is secured to an outside portion of the envelope (6) in proximity to the given region and an inner tube (32) is disposed within the outer tube (18) such that a fluid passageway (36) is defined between the inner and outer tubes. A hollow retractable electrode (10) is provided within the inner tube (32), the electrode (10) having a first position in which its tip portion is in proximity to the given region of the envelope when the lamp is being started and a second position in which the tip portion is away from the envelope after the lamp is started. A source of cooling fluid is connected to the hollow electrode (10) such that the cooling fluid is forced through the hollow electrode (10) and exhausted through the fluid passageway (36).
摘要:
An electrodeless lamp comprises an envelope (4) containing a fill; a starting electrode (10) which is in proximity to a given region of the envelope when the lamp is started; excitation power means (15) for coupling microwave or RF power to the fill which is sufficient to sustain a discharge; a substance (13) for facilitating the starting of the lamp contained inside the envelope containing an element selected from the group of cesium, sodium, potassium, and rubidium; means for insuring that upon removal of the microwave or RF power, the substance is present at the given region of the envelope; means for applying power (14) to the electrode for starting the lamp which results in the application of an electric field to the substance; and means for removing power (26) from the electrode after the lamp is started. A method on starting an electrodeless lamp comprises the steps of providing a bulb comprised of an envelope and discharge forming fill in the envelope; causing a field emission source to be disposed on the interior surface of the envelope at a given region; applying an electric field at the given region of the envelope which is sufficient to cause field emission from the field emission source; and coupling microwave or RF power to the fill which is sufficient to sustain a discharge.
