摘要： Prefoamed polypropylene-base particles have a crystalline structure featuring a high-temperature peak appeared on the higher temperature side than the peak inherent to polypropylene-base resins on a DSC curve obtained by differential scanning calorimetry upon heating 1-3 mg of the prefoamed polypropylene-base particles at a constant heating rate of 10.degree. C./min. to 220.degree. C. by means of a differential scanning calorimeter and the internal pressure decreasing velocity coefficient k of the particles is either equal to or smaller than 0.70 (k.ltoreq.0.70) at 25.degree. C. and 1 atm. The prefoamed polypropylene-base particles can be formed into an expansion-molded polypropylene-base article by imparting foamability to the particles, filling the resultant particles in a mold and then heating the particles so as to cause their expansion. The expansion-molded article has good surface quality, excellent dimensional accuracy, and superb physical properties such as shrinkage factor, compression hardness, compression set and interparticle fusion-bonding property.

摘要： A slider for a linear motion rolling guide unit can ensure a smooth rolling movement and a reliable lubricating capability and eliminate the need for accurate dimension control to reduce the manufacturing costs. A turning corner 9 in an end cap 2 is made up of a pair of arced paths 9c connecting with a rolling path in the casing 1, and a straight path 9d providing a connection between the arced paths 9c and extending in a direction approximately perpendicular to the rolling path. The lubricating member A mounted in the end cap 2 has a lubricating face 18a exposed to the linear path 9d, and maintains a relation of the lubricating face 18a intersecting the outer peripheral faces of the arced paths 9c. A recessed area 19 is formed between the outer peripheral face of each arced path and the lubricating face 18a in a surplus length region extending outward from the intersection between the lubricating face 18a and the outer peripheral face of the arced path 9c.

摘要： A linear motion guide unit is disclosed in which a tubular composition to provide a return passage is high in mechanical stiffness and also makes certain of sustainable application of lubricant to rolling elements rolling through the return passage, thereby ensuring proper lubrication under maintenance-free operation. The tubular composition to make the return passage is composed of a tubular skeleton to guide the rollers, and a porous compact impregnated with lubricant. The tubular skeleton is made up of forward and aft ends, a lengthwise column and a flexible spine, which extend between the ends. The flexible spine includes lengthwise opposite relief portions and a flexible middle section, which fit into the porous compact with separating from the porous compact to make a clearance between them. The flexible spine deflects as the rollers roll through the return passage, permitting the rollers coming into touch with the porous compact to lubricate the rollers.

摘要： Pre-foamed particles of an uncrosslinked, linear low-density polyethylene have a crystalline structure characterized in that two endothermic peaks appear on a DSC curve obtained by differential scanning calorimetry of the pre-foamed particles (said DSC curve having been obtained by heating 1-5 mg of the pre-foamed particles to 220.degree. C. at a rate of 10.degree. C./min by a differential scanning calorimeter) and the energy at the endothermic peak on the higher-temperature side is 5 J/g or more. A process for the production of the pre-foamed particles of the uncrosslinked, linear low-density polyethylene is also disclosed.
