摘要： PROBLEM TO BE SOLVED: To provide a filament device which does not generate a position shift of a filament tip in use, compared with a prior art. SOLUTION: A distortion of a tungsten wire 3 by a heat generated in use of the filament device is prevented by forming the tungsten wire 3 into a V-form folded only at a point of its center portion of it, forming a folding portion B folded to a mutually approached direction from a parallel portion P penetrating an insulator 1 on a end side of a pair of pins 2a, 2b fixing both ends, and fixing both ends of the tungsten wire 3 to the folding portion B by welding to facilitate a folding of the tungsten wire 3 in the same plane and reduce a possibility for a distortion stress or the like caused by a heat on welding to remain in the tungsten wire 3.

摘要： PROBLEM TO BE SOLVED: To increase a thermoelectron emitting amount with a simple structure. SOLUTION: A central area of a filament body 1 formed by a LaB6 material is to be as an electron emitting area 2 as well as an electron emitting surface 3 is formed to the electron emitting area 2. An electron emitting amount is increased by annularly bending the electron emitting surface 3 to expand its surface. It may attempt to stabilize a temperature of the electron emitting area 2 by forming a temperature compensation area 5 around the electron emitting area 2.

摘要： PURPOSE:To use a hot cathode structural body for a long period without breaking it near the junction of a conducting ceramic by connecting a metal piece on the inside of the conducting ceramic, and connecting the current guide terminal junction between the metal piece and an insulating material. CONSTITUTION:When a conducting ceramic 1 is used as a heating element, a metal piece 2 is connected on the inside of the ceramic 1, and a current guide terminal junction 3 is pinched and connected in the horizontal direction between the metal piece 2 and an insulating material (insulator) 4. The size difference between the inner size of the ceramic 1 and the metal piece 2 is set to 20mum or below, and the metal piece 2 electrically connects the ceramic 1 and the junction 3 and fixes the insulating material 4 at the preset position. The junction 3 is pinched and connected in the horizontal direction between the metal piece 2 and the insulating material 4, and the generation of stress due to the expansion of the metal junction 3 having a larger thermal expansion coefficient can be avoided. The occurrence of cracks by the thermal stress near the connection end section of the ceramic 1 emitting thermoelectrons is prevented, and a long life can be obtained.
