| 发明名称 | Vacuum tube | ||
| 摘要 | A vacuum tube includes a filament and two pairs of a grid and an anode. The filament is tensioned linearly and emits thermoelectrons. Both of the anodes are formed on a 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 of a 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 further includes an intermediate filament fixing part fixing the filament at a position corresponding to an intermediate point between the anodes of the two pairs. | ||

| 主权项 | 1. A vacuum tube comprising a filament and two pairs of a grid and an anode, wherein the filament is tensioned linearly and emits thermoelectrons; both of the anodes are formed on a same face of 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 of a 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 further comprises an intermediate filament fixing part fixing the filament at a position corresponding to an intermediate point between the anodes of the two pairs; and the intermediate filament fixing part is at a position that divides the filament into two halves. | ||
