    • A light guide body includes: at least a front end tapered portion including one end connectable to an optical fiber and the other end, the one end being thinner than the other end; a plurality of second taper portions, each including one end connectable to an optical fiber and the other end, the one end of the second taper portion being thinner than the other end of the second taper portion; and a main body connected to the other ends of the first and second taper portions. The front end tapered portion, the main body, and the second taper portions provide transmission of incident light with division between the one end of the front end tapered portion and the one ends of the second taper portions.
    • 导光体包括:至少前端锥形部分,其包括可连接到光纤的一端,而另一端的一端比另一端更薄; 多个第二锥形部分,每个第二锥形部分包括可连接到光纤的一个端部,另一端部的第二锥形部分的一端比第二锥形部分的另一端更薄; 以及连接到第一和第二锥形部分的另一端的主体。 前端锥形部分,主体和第二锥形部分提供在前端锥形部分的一端与第二锥形部分的一端之间分开的入射光的透射。

    • A magnetic disk cartridge has a first cassette shell half provided with engagement holes and a second cassette shell half provided with engagement pins. Each engagement hole has an entrance portion enabling insertion of an engagement pin and a shoulder-like engagement portion following the entrance portion. Each engagement pin has an elastic structure enabling it to be compressed and is formed at its tip portion with a bulged portion. The bulged portion is formed at its distal end with a tapered portion and at its proximal end with a sloped provisional retaining surface. The first and second cassette shell halves are formed on inner surfaces thereof with abutting surfaces. The cassette shell halves are provisionally assembled in the final assembly step by bringing the sloped provisional retaining surface of the bulged portion of the engagement pin engaged with the engagement hole into engagement with the shoulder-like engagement portion and bringing the abutting surfaces into abutment with each other. The cassette shell obtained by provisionally assembling the cassette shell halves therefore has high dimensional precision and can be easily disassembled before permanent assembly if necessary.
    • 磁盘盒具有设置有接合孔的第一盒壳半部和设置有接合销的第二盒壳半部。 每个接合孔具有能够插入接合销和入口部分之后的肩状接合部的入口部。 每个接合销具有使其能够被压缩并且在其尖端部分处形成有凸出部分的弹性结构。 凸起部分在其远端处形成有锥形部分,并且在其近端处形成有倾斜的临时保持表面。 第一和第二盒壳半部在其内表面上形成有邻接表面。 通过使接合销的凸出部分的倾斜临时保持表面与接合孔接合而与最终组装步骤暂时组装在一起,使其与肩状接合部分接合并使邻接表面与每个 其他。 因此,通过临时组装盒壳半部获得的盒壳具有高尺寸精度,并且如果需要,可以容易地在永久组装之前拆卸。

    • An injection molding method and apparatus in which an injection molding metal mold having a valve gate 7 mechanically opening and closing a gate facing an injection molding cavity is used, and the timing of closing the valve gate is set with reference to a melted resin pressure in the injection molding cavity during a holding pressure step in a molding process. The molding method and apparatus result in high accuracy molded products by utilizing a valve gate system in the injection molding of thin products, and also result in molded products having less variations among cavities even in the case where a plurality of products are molded at the same time.
