摘要： A magnetron has an anode cylinder, a plurality of vanes arranged radially within the anode cylinder, a magnetic piece disposed at an open end section of the anode cylinder, an anode vacuum container including a metal container disposed to cover an upper surface of the magnetic piece, a cathode disposed along a central axis of the vacuum container, and an antenna externally discharging microwaves. The magnetic piece and the metal container are placed, in that order, on a shelf formed inwardly on a thin end section projecting from the open end section of the anode cylinder. When tightly welding the thin end section, a predetermined number of projections, projecting inwardly from the thin end section of the anode cylinder, loosely secure an outer perimeter bend of the metal container. The metal container is then accurately tightly welded to the anode cylinder without the metal container shifting off-center.

摘要： A ring-shaped depressed groove 11 is formed between a joining surface 10 of a stem insulating material 6 with a tubular metal container 16 and a joining surface 9 with cathode leads 2a and 2b. A metallized layer 8, formed at joining surface 9 and joining surface 10, is separated from edges 12 and 13 of ring-shaped depressed groove 11. The resulting magnetron reliably prevents discharges generated between the joining surface of the stem insulating material, with the tubular metal container, and the joining surface, with the cathode leads.

摘要： A magnetron including a tubular metallic container which is air-tightly connected to an anode, cathode leads for supporting a cathode with filaments being disposed in a central axial portion of the anode, a stem insulator formed with through holes through which the cathode leads pass, and external terminals formed with planar portions which are air-tightly connected to a surface of the stem insulator opposite to a surface facing the tubular metallic container and with connecting portions which are air-tightly connected to the cathode leads. The connecting portions are arranged to be bent in an axial direction of the cathode leads. It is possible to exhibit the effect of preventing vacuum break from occurring by oxidation or the like since the increase in the area of the connecting portions will result in elongation of the distance between the end portions of the connecting portions and the through holes.
摘要翻译：一种磁控管，其包括气密地连接到阳极的管状金属容器，阴极引线，用于支撑阴极，灯丝设置在阳极的中心轴向部分;杆绝缘子，其形成有阴极引线通过的通孔，以及形成有平坦部分的外部端子，其气密地连接到与所述管状金属容器相对的表面的所述杆绝缘体的表面，以及气密地连接到所述阴极引线的连接部分。连接部被布置成沿着阴极引线的轴向弯曲。由于连接部分的面积的增加将导致连接部分的端部和通孔之间的距离的伸长，所以可以表现出通过氧化等发生防止真空断裂的效果。
