Lamp filament design
InactiveUS20050094989A1Domestic stoves or rangesDrying solid materials with heatThermal dilatationEngineering
An improved support is provided for locating a lamp filament axially within a lamp sleeve. The illustrated support is a spiral coil that includes a small diameter center portion that makes contact with the filament. On either side of the filament-contacting portion, the coil opens up to larger diameters for contacting the inner wall of the quartz sleeve within which the filament is housed. The support thus appears H-shaped when viewed from the side. A lamp filament is also provided with expansion compensation sections at either end of a central section. The filament wire in the compensation sections is wound into coils having a greater diameter and also a greater spacing between windings, as compared to coil in the central section. The expansion compensation sections are preferably capable of compressing and thereby absorbing thermal expansion of the filament during operation, without shorting the filament across adjacent windings.

PCT No. PCT / JP97 / 01976 Sec. 371 Date Feb. 20, 1998 Sec. 102(e) Date Feb. 20, 1998 PCT Filed Jun. 10, 1997 PCT Pub. No. WO97 / 49108 PCT Pub. Date Dec. 24, 1997Problems with a conventional cathode for electronic tubes arose because metals composing the substrate were subjected to heat deformation, resulting in a relatively lage drift of cutoff voltage. The present invention diminishes the heat deformation of the substrate to obtain a cathode with a small drift of cutoff voltage. Particularly, heat expansion coefficients can be made uniform while metals in the metal layer are prevented from diffusing into the substrate. This is done by incorporating the same metals present in the metal layer into the metals composing the substrate, thereby supressing deformation of the substrate.
