摘要： A knock type applicator includes a cylindrical shell having a coating liquid storage chamber, a writing tip slidably inserted into an opening portion formed in a distal end of the cylindrical shell, and a valve mechanism between the writing tip and the coating liquid storage chamber. The valve mechanism has a valve element connected to the writing tip. Ribs are formed in an inner wall of the opening portion of the cylindrical shell in a lengthwise direction of the cylindrical shell. The diameter of an inscribed circle connecting apexes of the ribs is dimensioned smaller than the maximum diameter of the writing tip. By this, the ribs bite or project into the writing tip which is advanced in combination with the valve element during knocking operation. As a consequence, the writing tip is cracked by the ribs projected therein. At that time, hardened substance, gelled substance and viscous substance created from the coating liquid in the writing tip are peeled off from the fibers of the writing tip, thus recovering an ink flow passage in the writing tip. A connecting force between the writing tip and the valve element is set smaller than a biasing force exerted to the valve element, and a joining distance between the writing tip and the valve element is set longer than a moving distance of the valve element during knocking operation. Thus, the writing tip would not escape from the valve element even if the knocking force is released by mistake when the hardened substance, gelled substance, etc. of the coating liquid is removed from the writing tip.

摘要翻译： 敲击式涂抹器包括具有涂布液储存室的圆筒形壳体，可滑动地插入到形成在圆筒形壳体的远端中的开口部分中的书写尖端以及在书写尖端和涂布液体存储室之间的阀机构。 阀机构具有连接到书写尖端的阀元件。 在筒状壳体的开口部的内壁沿筒状壳体的长度方向形成肋。 连接肋的顶点的内接圆的直径尺寸小于书写尖端的最大直径。 由此，肋骨在敲击操作期间咬合或突出到与尖头组合的书写尖端中。 因此，书写尖端被突出在其中的肋裂开。 此时，从笔尖的涂布液产生的硬化物质，凝胶物质和粘性物质从书写尖端的纤维剥离，从而在笔尖上回收墨水流路。 书写尖端和阀体之间的连接力被设定为小于施加到阀体上的偏压力，并且书写尖端和阀体之间的接合距离被设定为比在敲击操作期间阀元件的移动距离长 。 因此，即使当涂布液的硬化物质，凝胶物质等从书写尖端移除时，即使敲击力被错误地释放，写入尖端也不会从阀元件逸出。

摘要： A refractory of the invention is used in casting operation, which has good spalling resistance and corrosion resistance. The refractory includes: 0.0357-2.6548 wt % of amorphous silica particles having a specific surface area within a range of 15-30 m.sup.2 /g; 8.8495-28.5612 wt % of alumina particles having a particle diameter within a range of 10-50 mm; 1.3986-18.1715 wt % of at least one of fused magnesia and sintered magnesia, which contains 0.6993-10.9041 wt % of magnesia having a maximum particle diameter under 44 .mu.m; 0.6993-13.630 wt % of alumina cement; and 45.4545-88.1417 wt % of alumina. When the refractory is used, at lease one of fused magnesia and sintered magnesia surrounds the alumina particles, which react together to generate spinel to thereby form micro-crack layer around the alumina particles for preventing propagation of cracks in a refractory structure.
