Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
59 words
A sliding member made of a material consisting of 0.1-15 percent by weight of an organic fiber material having a length less than about 3mm. and a diameter of about 15-50 microns and having oil affinity, 1-15 percent by weight of a hydrocarbon lubricating oil, 0.1-10 percent by weight of a metallic soap, and the balance of polyacetal resiN.
Claim 2
Dependent Claim
68 words
A sliding member made of a material consisting of 0.1-15 percent by weight of an organic fiber material having a length less than about 3mm. and a diameter of about 15-50 microns and having oil affinity, 1-15 percent by weight of a hydrocarbon lubricating oil, 0.1-10 percent by weight of a metallic soap, 0.1-10 percent by weight of a solid inorganic lubricant, and the balance of polyacetal resin.
Claim 3
Independent Claim
88 words
A method of manufacturing a sliding member which comprises mixing and stirring in a container from 0.1-15 percent by weight of an organic fiber having a length less than about 3mm. and a diameter of about 15-50 microns and having oil affinity, from 1-15 percent by weight of a hydrocarbon lubricating oil, and polyacetal resin as the balance, heating to a temperature above the melting point of the resin to melt the composition, solidifying the composition, crushing the solidified composition, molding the crushed composition into a sliding member.
