    • An electron tube such as a fluorescent display tube is provided. Auxiliary linear support members (e.g. linear spacers and linear dampers), which subsidiarily support liner members (e.g. cathode filaments and wire grids), are bonded on a substrate, using ultrasonic welding (without using an adhesive agent (e.g. fritted glass or a conductive paste)). A metal layer (e.g. a thin or thick aluminum film) is formed over the glass substrate. The end of the coil of a cathode filament is securely bonded to the metal layer. A spacer of a metal wire (e.g. aluminum) is ultrasonic welded to the metal layer. The welding is performed with the wedge tool of an ultrasonic welder placed at the position where the spacer is in contact with the cathode filament. A U-shaped recess is left at the welded spot. This recess prevents the cathode filament from being displaced. If necessary, the metal layer is formed over the substrate and the damper of a metal wire (e.g. aluminum) is disposed to prevent the vibration of the cathode filament.
    • 提供诸如荧光显示管的电子管。 使用超声波焊接(不使用粘合剂(例如多孔玻璃或导电浆料))将辅助线性支撑构件(例如线性间隔件和线性阻尼器)辅助地支撑衬里构件(例如阴极细丝和线栅) ))。 在玻璃基板上形成金属层(例如薄的或厚的铝膜)。 阴极丝的线圈的端部牢固地结合到金属层。 金属线(例如铝)的间隔件被超声波焊接到金属层。 焊接通过放置在隔离件与阴极细丝接触的位置处的超声焊接机的楔形工具进行。 U形凹槽留在焊接点。 该凹槽防止阴极丝被移位。 如果需要,金属层形成在基板上,金属线(例如铝)的阻尼器被设置以防止阴极丝的振动。
