    • A color picture tube device that can suppress the deformation of the electron beam spot shape and improve the horizontal resolution using a simple construction is provided. A horizontal deflection coil generates a horizontal deflection magnetic field that is substantially uniform. A plurality of electron beams are substantially parallel with the tube axis when passing one end of a core of a deflection yoke facing an electron gun. A lens forming unit forms a lens through which the plurality of electron beams pass, between the electron gun end of the core and a phosphor screen. The lens has an effect of causing the plurality of electron beams to approach each other in a horizontal direction, irrespective of which part of the phosphor screen the plurality of electron beams reach.

    • A resin-molding mold unit and a resin-molding apparatus having the resin-molding mold unit are capable of removing any air trap from a molten resin therein. This makes it possible to produce a molded product which is free from any void and therefore improved in appearance. In order to enhance demolding of the molded product from the resin-molding mold unit, this resin-molding mold unit has a pin hole in which an ejection pin is received to have its front end portion extend into a molding space from an inner wall surface thereof by a length which is adjustable, if necessary. The front end portion assumes a semispheric shape. In injecting the molten resin, the ejection pin is adjusted in position so as to have its outer peripheral edge portion aligned in level with the inner wall surface. Since the molten resin thus injected flows along the semispheric front end portion, any air trap is not formed in the vicinity of the ejection pin, particularly, in a downstream side thereof.
    • 具有树脂成型模具单元的树脂成型模具单元和树脂模制装置能够从其中的熔融树脂中去除任何空气阱。 这使得可以生产没有任何空隙并因此改善外观的模制产品。 为了增强模制产品从树脂模塑单元的脱模,该树脂模塑单元具有销孔,销孔被容纳在其中,使得其前端部分从内壁表面延伸到模制空间中 如果需要,其长度可调。 前端部呈半球状。 在注入熔融树脂时,将排出销调整到位置,使其外周边缘部分与内壁表面平齐。 由于这样注入的熔融树脂沿着半球形前端部流动,所以在喷射销附近,特别是在其下游侧不形成任何空气阱。

    • For forming a tubular work into a shaped hollow product by using hydroforming process, a method and a device are described. In the method, female and male dies are prepared. The female die has a longitudinally extending cavity which has a polygonal cross section when receiving the male die. The tubular work is placed into the cavity of the female die. The interior of the tubular work is then fed with a hydraulic fluid, and the pressure of the fluid is increased to a given level. The given level is smaller than a critical level that causes a bulging of the tubular work. The male die is then pressed against the tubular work to deform the same while keeping the hydraulic fluid at the given level, thereby forming a shaped hollow product that has a polygonal cross section that conforms to that of the cavity. The pressing work is continued until a circumferential length of the shaped hollow product becomes shorter than that of the tubular work.
    • 为了通过使用液压成型工艺将管状工件形成成型的中空产品,描述了一种方法和装置。 在该方法中,制备阴模和阴模。 阴模具有纵向延伸的空腔,当接收阳模时,其具有多边形横截面。 将管状工件放入阴模的空腔中。 然后,管状工件的内部被供给液压流体,并且流体的压力增加到给定的水平。 给定的水平小于导致管状工作膨胀的临界水平。 然后将阳模压在管状工件上以使其变形,同时将液压流体保持在给定的水平,从而形成具有与腔的多边形横截面一致的成形中空产品。 压制工作继续进行,直到成形中空制品的圆周长度变得短于管状工件的圆周长度。
