    Abstract: An energy converter according to the present invention includes a filament 11 for converting given energy into electromagnetic waves and radiating the waves, and a radiation suppressing portion for suppressing some of the electromagnetic waves (e.g., infrared rays), which have been radiated from the filament 11 and of which the wavelengths exceed a predetermined value. The radiation suppressing portion has a bundle 12 of fine wires 12a, of which the axial direction is aligned with a direction in which the electromagnetic waves propagate with their radiations suppressed.

    Abstract: A method of forming tungsten ingots having improved uniformity of density and improved uniformity in distribution of dopant within the ingot is disclosed. Doped tungsten powder is disposed in a cylindrical mold having sealing means at both ends. The powder completely fills a void space within the mold between the sealing means so that there is substantially no settling of the powder. A pressure of about 560 kg/cm.sup.2 is applied uniformly to the outer surface of the mold to form a cylindrical compact. The compact is removed from the mold and resistance sintered to a density of at least about 85 percent of theoretical density to form the ingot.

    Abstract: A method for manufacturing a high ductility and high hot tensile strength tungsten wire for incandescent lamp filaments is disclosed. The method comprises the steps of preparing a tungsten alloy, swaging a tungsten rod from the alloy, and drawing the swaged rod to wire size in multiple drawing passes. In the method, the wire is annealed between predetermined draws. It is proposed that an annealing is performed before the final drawing pass, by annealing the wire at a temperature between 1100-1300° C.There is also provided a tungsten wire for incandescent lamp filament, which has high ductility and high hot tensile strength. The tungsten wire of the invention has a cold tensile strength-hot tensile strength ratio not exceeding 3.5.
