摘要： A write element for perpendicular recording in a data storage system is fabricated to maintain the thickness of a side shield at both edges of a pole P3, and to form the pole P3 in a trapezoidal shape. Forming a side shield around the pole P3 removes stray fields, creating a quiet, noise-free write element and preventing side erasure. The fabrication method utilizes a magnetic buffer layer to protect a shield gap during trim of the pole P3, and thus to provide the shield gap with a uniform thickness. The magnetic buffer layer also protects the shield gap and pole P3 when the top hard mask is removed. Consequently, the write field is made uniform across the track width. The fabrication method uses a metal in the shield gap to improve the pole geometry after pole trim and to provide a uniform edge to the pole P3.
摘要翻译：制造用于在数据存储系统中进行垂直记录的写入元件，以将侧屏蔽件的厚度保持在极点P 3的两个边缘处，并且形成梯形形状的极点3。在P 3周围形成一个侧面屏蔽可去除杂散场，创建一个安静，无噪音的写入元件，并防止侧面擦除。该制造方法利用磁性缓冲层来保护极P 3的修整期间的屏蔽间隙，从而提供具有均匀厚度的屏蔽间隙。当去除顶部硬掩模时，磁缓冲层还保护屏蔽间隙和极点P 3。因此，写入磁道在磁道宽度上是均匀的。制造方法使用屏蔽间隙中的金属来改善极修整之后的极几何形状，并且向极P 3提供均匀的边缘。

摘要： A ball game net rod structure includes a net body. The net body is supported by a net frame formed from lateral rods, upper rods and lower rods connected in series. Rod bodies of the upper rods or lower rods are wide V-shaped. A unidirectional connecting portion is disposed at two corresponding ends of the rod bodies. The unidirectional connecting portion includes a substantial D-shape, an arc disposed above the D-shape, and three straight sides connected thereto, or has at least a side with a narrow V-shaped indentation portion. When the paired rod bodies are connected, the connection is effectuated in only one direction. The unique direction ensures that tips of the wide V-shaped rod bodies point up or down to thereby stretch the net body or enable the net body to bear the brunt of a ball; hence, the net body is taut and pleasant when fully mounted.

摘要： A vertical aerial assembly for the volleyball includes a lower fixing rod, a lower screw member, an aerial, a handle, an upper screw member, and an upper fixing rod. The vertical aerial assembly has a simplified construction with fewer parts, thereby decreasing the cost of fabrication. In addition, the vertical aerial assembly is assembled easily and conveniently, thereby saving the time of assembly. Further, the handle only needs to form a through hole to fit the outer diameter of the aerial without having to additionally provide a stepped hole, thereby decreasing the cost of fabrication.
