    • A laser machining apparatus capable of performing high-quality and precise cuts on sharply angled or complexly configured portions of a plate-type workpiece with minimum burn-through loss of material due to thermal saturation. In accordance with the invention, values are prestored representing optimum laser output with respect to the speed of the laser beam relative to the workpiece for various types of workpiece material and thickness of the workpiece. These values are read out and the laser beam controlled in accordance therewith during cutting operations. Some of the values represent a continuous output and are applied for higher speed cutting, while others represent a pulsed output and are applied for lower speed cutting.
    • 激光加工设备,能够对板式工件的锐角或复杂配置的部分进行高质量和精确的切割,同时由于热饱和而具有最小的材料烧穿损失。 根据本发明,预先存储的值表示针对各种工件材料和工件厚度相对于激光束相对于工件的速度的最佳激光输出。 在切割操作期间读出这些值并根据激光束进行控制。 一些值表示连续输出,适用于更高速度切割,而其他值代表脉冲输出,并用于较低速度切割。

    • A control electrode portion for passing electrons through a given electron-passing hole selected from a plurality of electron-passing holes provided on an insulating substrate is formed by coating the insulating substrate with a conductive film and dividing the into a plurality of conductive films as control electrodes. This structure obviates the mesh structure of electrons which are necessary in the case of arranging control electrodes on the insulating substrate, thereby realizing high-definition display devices with improved luminance. In addition, planar display devices provided with a surface insulated substrate produced by forming an insulating film on a conductive substrate having electron-passing holes and a plurality of separate control electrodes arranged on the surface insulated substrate, it is possible to prevent the charge-up effect which obstructs the passage of electron beams and, hence, to enhance the luminance at least by (1) providing a voltage applying circuit for applying a predetermined voltage to the conductive substrate, (2) providing a portion at which the conductive substrate is exposed between the adjacent control electrodes.
    • 通过用导电膜涂覆绝缘基板并将其分成多个导电膜作为对照,形成用于使电子通过选自设置在绝缘基板上的多个电子通过孔中的给定电子通过孔的控制电极部分 电极。 这种结构消除了在绝缘基板上布置控制电极的情况下必需的电子的网格结构,从而实现了具有改善的亮度的高清晰度显示装置。 另外,具有通过在具有电子通过孔的导电性基板上形成绝缘膜而形成的表面绝缘基板的平面显示装置和配置在表面绝缘基板上的多个分立控制电极,能够防止充电 至少通过(1)提供用于向导电衬底施加预定电压的电压施加电路,(2)提供导电衬底露出的部分,从而阻止电子束通过,并因此提高亮度 在相邻的控制电极之间。
