摘要： The present invention relates to a T-shaped connection frame for connecting car frames, in which a first member is connected to a second member via a joint member to form a "T." The joint member is formed by symmetrically dividing a rectangular tube between its two latch teeth located at the upper-center and lower-center inner walls. The rectangular tube also has protrusions at the left and right exterior walls. The joint member divided in this way has the latch teeth at the upper and lower tips of the mouth formed by the division and has the protrusion situated opposite the mouth so that the first member can be snapped on easily to this mouth and the second member can be attached to the protrusion at the opposite side. This structural arrangement makes the positioning of the frames very simple, obviates a make-shift attachment, and, at the same time, reduces the number of operation steps.
摘要翻译： 本发明涉及一种用于连接轿厢框架的T形连接框架，其中第一构件经由接头构件连接到第二构件以形成“T.” 接头构件通过将矩形管对称地分配在位于中心中心和下中心内壁的两个闩锁齿之间来形成。 矩形管也在左右外壁上具有突起。 以这种方式分割的接头构件在由分隔开口形成的口的上端和下端处具有锁定齿，并且具有与口相对的突出部，使得第一构件可以容易地卡扣到该口上，并且第二构件可 附着在相对侧的突出部。 这种结构布置使得框架的定位非常简单，避免了换档附件，并且同时减少了操作步骤的数量。

摘要： The can end is formed with a circular severing score for severing the area defined thereby from the can end by pulling a manipulating tab secured within the area defined by the score at a position adjacent thereto. In order to increase the pressure resisting strength against the internal pressure caused by the content in the can, the can end is made from a thin aluminum alloy sheet having the yield strength in the range of 24-29 kgf/mm.sup.2 as well as the elongation equal to or greater than 6%, while the aperture rate defined by the ratio of the area formed within the score with respect to the total area of the can end is made at least equal to or greater than 60% so that the pressure resisting strength is kept substantially at least 5 kgf/cm.sup.2. In order to more advantageously maintain the high pressure resisting strength of the can, score is located at a position spaced from the inner periphery of the bottom of the frustoconical portion at least a distance equal to or greater than 1 mm inwardly of the area of the can end, to make the inner radius of curvature of the corner formed around the inner periphery of the bottom of the frustoconical portion equal to or less than 0.5 mm, and to make the taper angle of the frustoconical portion of the can end equal to or less than 10.degree.. An auxiliary score having a score residual smaller than that of the score for severing the area defined thereby from the can end may be formed outwardly or inwardly of the score for severing. The score residual of the can end may be preferably increased from the thinnest portion adjacent to the position where the tab is provided while a plurality of elongated ridges or grooves may be formed within the area defined by the score substantially perpendicular to the line passing through the tab and the center of the can end in order to avoid rapid severing of the area defined by the score from the can end so as to prevent spilling of the content out of the can when the can end is being opened. All these measures are effective to most advantageously enhance the pressure resisting strength of the can end.
