摘要： The vacuum tube subject to the present invention comprises a filament and two pairs of a grid and an anode. The filament is tensioned linearly and emitting thermoelectrons. Both of the anodes are formed on the same face on a planar substrate. The filament is arranged parallel to the planar substrate at a position facing both of the anodes. Each of the grids is arranged, such that the grid faces the anode in the same pair at a first predetermined distance from the anode and has a second predetermined distance from the filament, between the anode and the filament. The vacuum tube comprises an intermediate filament fixing part fixing the filament at a position corresponding to an intermediate point between the anodes of the two pairs.

摘要： An object of the present invention is to provide a vacuum tube with a structure close to that of an inexpensive and easily available vacuum fluorescent display which easily operates as an analog amplifier. A vacuum tube subject to the present invention comprises: a filament which is tensioned linearly and emits thermoelectrons, an anode arranged parallel to the filament, and a grid arranged between the filament and the anode such that the grid faces the anode. The present invention is characterized in that a distance between the filament and the grid is between 0.2 mm and 0.6 mm, including 0.2 mm and 0.6 mm.

摘要： An analog amplification vacuum tube of the present invention suppresses influences of filament vibration on amplification characteristics. The analog amplification vacuum tube of the present invention is provided with a filament, an anode, a grid and a vibration-proof part. The filament is tensioned linearly and emits thermal electrons. The anode is disposed parallel to the filament. The grid is disposed between the filament and the anode so as to face the anode. The vibration-proof part includes a thin film usable in a vacuum environment and the thin film comes into contact with part of the filament.
