[Title <strong>of</strong> the Invention]<br />
Twisted yarn applied to the surface <strong>of</strong> fiber bearing, and the bearing made by using this twisted<br />
yarn<br />
[Claims]<br />
1. A twisted yarn used on the surface <strong>of</strong> a low-friction fiber bearing including a TFE fine yarn<br />
(10) used at the volume rate <strong>of</strong> up to 50%; a multiple wound yarn (11) made from<br />
high-temperature nylon, wherein the TFE fine yarn is loosely wound around a nylon<br />
multiple-wound yarn used as a core; and wherein synthetic resin can feed into the entire<br />
multiple loosely twisted yarn. (See Figure. 1.)<br />
2. A bearing, wherein a twisted yarn including a TFE fine yarn (10), (13 “) used at the volume<br />
rate <strong>of</strong> up to50% and a multiple wound yarn made from high-temperature nylon (11), (13”) is<br />
exposed on the surface <strong>of</strong> a bearing (15); wherein said TFE fine fiber is loosely wound<br />
around a nylon multiple-wound yarn used as a core, whose glide plain is equipped with<br />
hardened synthetic resin (14) with an affinity <strong>for</strong> said twisted yarn and <strong>for</strong>ming a continuous<br />
solid object with no space. (See Figure 1, 2 and 3)<br />
[Excerpt <strong>of</strong> Detailed Description <strong>of</strong> the Invention and Drawings]<br />
This invention relates to a twisted yarn making up a low-friction fiber bearing and a fiber.<br />
The object <strong>of</strong> this invention is to hold a TFE fine yarn more securely against the rotation (at the<br />
portion where breakage occurs easily) by being equipped with a rein<strong>for</strong>cing material <strong>for</strong> a<br />
low-friction fiber on the surface <strong>of</strong> a bearing.<br />
The bearings made by using a conventional tetra-fluoroethylene (TFE) fine yarn in order to<br />
gain low friction causes extreme abrasion and rapid fracture under a maximum load or more.<br />
Additionally, the maximum working temperature must be carefully controlled because a<br />
mechanical function decreases under a load or at the time <strong>of</strong> a rise in temperature.<br />

[Explanation]<br />
Though the technical field <strong>of</strong> the specified invention (Claim 1) is a twisted yarn and that <strong>of</strong><br />
the related invention (Claim 2) is a fiber bearing, it is described in the Claims that a twisted yarn<br />
is applied to a fiber bearing, and so there<strong>for</strong>e the technical fields <strong>of</strong> both inventions are<br />
technically and directly associated with each other and their industrial fields <strong>of</strong> application are<br />
the same. In addition, a twisted yarn that is a new matter corresponding to the problem to be<br />
solved <strong>of</strong> the specified invention is equivalent to the substantial part <strong>of</strong> matter in the claim <strong>of</strong> the<br />
related invention; and so there<strong>for</strong>e the substantial parts <strong>of</strong> matters in the claims <strong>of</strong> both<br />
inventions are also the same.<br />
