    • 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。

    • A fluorescent display tube is disclosed. In the fluorescent display tube, linear members, such as, for example, wire grids and filament are sustained in a predetermined height, while both ends of each linear member are welded on a metal layer by ultrasonic. The fluorescent display tube includes a metal spacer for fixing the linear member and holding the linear members in an elevated position so that the dead space within the fluorescent display is reduced. The linear members are bonded on an aluminum thin films formed on the glass substrate 111 by way of the aluminum spacer. The aluminum spacer sustains the linear members in a predetermined height. Aluminum spacer acts as a member for fixing the linear member and as a height level holding member.
    • 公开了荧光显示管。 在荧光显示管中,线状构件例如线栅和长丝被保持在预定的高度,而每个线性构件的两端通过超声波焊接在金属层上。 荧光显示管包括用于固定直线部件并将直线部件保持在升高位置的金属间隔件,使得荧光显示器内的死区减小。 线状构件通过铝间隔物结合在形成在玻璃基板111上的铝薄膜上。 铝间隔件将线性构件保持在预定高度。 铝间隔件用作用于固定线性构件和高度水平保持构件的构件。
