    摘要: A pneumatic tire for off-road vehicles, which is highly durable under heavy load conditions is disclosed. The tire makes use as its breaker of a reinforcing element formed of material having a high cut resistant property such as steel or glass. The least possible number of those plies of a plurality of rubberized ply layers of a carcass body which extend from a crown portion of the tire through both side portions up to both bead members and which can substantially withstand internal pressure applied to the tire and external force subjected thereto is determined on the basis of a fundamental safety factor .xi. and which lies within a range of a correction safety factor .eta. which depends on the use and type of the tire and the depth of tread groove.

    摘要: This invention relates to an improvement in a pneumatic tire for construction vehicles. The improved tire makes use of a steel cord breaker, but can prevent mechanical and thermal separations in the tire. Breaker rubberized cords are designed to have a gap ratio given by ##EQU1## preferably 0.72 to 0.80, for the purpose of restraining the mechanical separation, where D is a distance between centers of two adjacent cords and d is a diameter of the cord. A tread rubber layer is designed to have a ratio R of a skid base S to a tire section height H given by ##EQU2## FOR THE PURPOSE OF RESTRAINING THE THERMAL SEPARATION.

    摘要: A graphite powder has surface closed-end structures in which the graphite c-plane layers of the graphite layer crystal lattices have closed-ends on the surface of the graphite powder by linking the ends of one or more pairs of the c-plane layers, leaving interstices which are open on the surface of the graphite. The number of open interstices is at least 100 and at most 1500 per micrometer in a c-axis direction of the graphite. Preferably, the graphite powder has a specific surface area of 1.0 m2/g or less. Such a graphite powder can be prepared either by graphitizing a carbon material, which has been pulverized at a high speed under well-controlled conditions before and/or after the carbonization, or by subjecting a carbon material, which has been pulverized under well-controlled conditions before and/or after the carbonization, to graphitization and then to oxidative heat treatment at a temperature of 600-800° C. and finally to heat treatment at a temperature of 800° C. or higher in an inert gas. The graphite powder can be used to produce negative electrodes of lithium ion secondary batteries having a high discharge capacity of at least 320 mAh/g and a high charge/discharge coulombic efficiency of at least 90%.
