    Abstract: A yarn in which slipping of filler materials from a tubular member can be reduced while suppressing the manufacturing cost is provided. The yarn has a tubular member, and a plurality of filler materials that are formed into a strip-like shape, and is configured by loading the filler materials into the tubular member in a state where the longitudinal directions of the filler materials are made extending along the axial direction of the tubular member. In the yarn, the tubular member is configured by using wire material that is knitted so as to produce stitches. The wire material has arcuate loop portions that define parts of external shapes of the stitches. In a state where the tubular member is developed, the loop portions are expanded in a direction that is inclined with respect to a straight line that extends in the axial direction of the tubular member.

    Abstract: A braided packing has a number of longitudinal strands around which a braid strand is wound in a lattice pattern to form a substantially square braid. The longitudinal strands include at least two lubricant sink strands, the lubricant sink strands having a material composition and configuration to give the lubricant sink strands a higher lubricant absorbency than the other longitudinal strands and the braid strand. The packing is immersed in a lubricating fluid which is absorbed and retained in higher amounts by the lubricant sink strands, thereby providing a long-lasting source of lubricant for the overall packing during use.

    Abstract translation: 编织填料具有许多纵向股线,编织线以丝网图案缠绕在其上,以形成基本上为方形的编织物。 纵向股线包括至少两个润滑剂汇股,润滑剂汇股具有材料组成和构造,以使得润滑剂水槽股线具有比其它纵向股线和编织线股更高的润滑剂吸收能力。 填料被浸入润滑流体中,该润滑流体被润滑剂槽股吸收并保持较高的量,从而在使用期间为整个包装提供长久的润滑剂来源。

    Abstract: A gasket is disclosed for shielding from electromagnetic emissions and interference (EMI) that exhibits excellent characteristics of recovery, bending, and tangential compression over a wide range of frequencies. The gasket comprises a knitted core of monofilament synthetic polymer yarns, and a circular warp knitted sheath over the monofilament knitted core, with the sheath being sufficiently conductive to provide shielding from electromagnetic interference over a wide range of frequencies.

    Abstract: A packing ring of a composite structure including a packing of expanded graphite and an annular mass of superposed sheets of expanded graphite is produced by a method including the steps of spirally winding a ribbon of expanded graphite into a roll, compression molding the roll into the packing, and incorporating the annular mass into the packing by compression molding within a molding die so as to give rise to at least one packed part having a higher density than the packing in at least one of the inner and outer peripheral parts of the packing, the seal device has an empty space through which a shaft passes and containing at least one such packing in the empty space to seal between the inner wall of the empty space and the outer peripheral surface of the shaft.
