    • A butterfly valve comprises a substantially cylindrical casing (20) having an annular valve seat (A) on its inner peripheral surface, and a valve disk (44) disposed within the casing (20) and rotatable about an axis (35). The valve disk (44) is formed at an outer peripheral edge portion with an annular groove (52) in which an annular valve seal (51) is partially fitted. The valve seal (51) is adapted for pressing contact with the valve seat (A) at a predetermined pressure and anchored in the annular groove (52) by resin (58) pressure-injected into the annular groove (52) through a resin injection channel (53) in communication with the groove. Accordingly, the seal pressure of the valve seal (51) on the valve seat (A) can be set to the predetermined value at all times even if the dimensions of the valve seat (A) and the valve disk (44) and the position of the axis of rotation (35) involve errors.
    • 蝶阀包括在其内周表面上具有环形阀座(A)的基本上圆柱形的壳体(20),以及设置在壳体(20)内并可围绕轴线(35)旋转的阀盘(44)。 阀盘(44)在外周边缘部分形成有环形槽(52),环形阀密封件(51)部分地装配在该环形槽中。 阀门密封件51适于以预定的压力与阀座(A)压力接触并通过树脂注入到环形槽(52)中的树脂(58)固定在环形槽52中。 通道(53)与凹槽连通。 因此,即使阀座(A)和阀盘(44)的尺寸以及阀座(A)的位置,也可以始终将阀座(A)上的阀密封件(51)的密封压力始终设定为规定值 的旋转轴(35)涉及错误。

    • A display device has an array formed on a substrate including a cathode wiring line layer, a gate wiring line layer and an insulating layer for electrically insulating the cathode wiring line layer and the gate wiring line layer from each other. Holes are formed at the crossing portion between the cathode wiring line layer and the gate wiring line layer so as to penetrate through the insulating layer, and resistive layer and an emitter layer are provided in the holes. The resistive layer has such a structure that conductive fine particles are dispersed in a base material of insulating fine particles, and the emitter layer is formed of a fine particle material. The insulating layer between the cathode electrode lines and the gate electrodes is formed of a silicon oxide film containing fluorine. When a large number of elements are formed over a large area in an electron emission device using fine particle emitters, there can be provided electron emission elements which can suppress the unevenness of the electron emission amount. According to the present invention, there can be provided a large-area and uniform display device which can be operated with a low driving voltage, and have a long lifetime.
    • 显示装置具有形成在包括阴极布线线层,栅极布线线层和绝缘层的基板上的阵列,用于使阴极布线层和栅极布线层彼此电绝缘。 在阴极布线层和栅极布线层之间的交叉部分处形成孔,以穿透绝缘层,并且在孔中设置电阻层和发射极层。 电阻层具有将导电性细颗粒分散在绝缘性细颗粒的基材中的结构,发射极层由细粒材料形成。 阴极电极线和栅电极之间的绝缘层由含氟的氧化硅膜形成。 当使用细粒子发射体的电子发射装置中,在大面积上形成大量的元件时,可以提供能够抑制电子发射量不均匀的电子发射元件。 根据本发明,可以提供一种能够以低驱动电压操作并且寿命长的大面积均匀的显示装置。
