Abstract: In order to solve the various conventional problems described above, the present invention provides a tire which is excellent in a braking property and a drivability (WET performance) on a wet road surface and which sufficiently displays an edge effect or a spike effect and is excellent in an on-ice performance (surface braking and driving performance). Further, the present invention provides a tire which enhances a workability in a plant and in which micro drain ditches exhibiting a water film-removing performance are surely formed. A foamed rubber layer provided on a surface of the tire substantially brought into contact with a road surface contains at least one inorganic compound powder having a particle diameter of 10 ?m or less in a range of 5 to 20 mass parts per 100 mass parts of a rubber component.

Abstract: This invention relates to a rubber composition capable of using in a tread rubber of a tire to improve both an initial gripping performance and a running stability of the tire as compared with those of conventional tires, and more particularly to a rubber composition formed by compounding an indene-containing C9-based resin having a softening point of 130° C.-190° C. and an indene content of 30-80 mass % into a rubber component.

Abstract: There is provided a disk recording apparatus capable of minimizing a servo error and recording in the last zone at the maximum one of the recording speeds specified in the apparatus or disk recording medium even if the disk recording medium is in poor condition. At any position during disk activation, an axial-run-out and eccentricity measuring circuit (115) measures the eccentricity of the disk recording medium. A CPU (101) calculates the upper-limit rotation speed from the measurement, divides the recording area into zones in such a manner that the disk recording medium rotates at speeds lower or equal to the upper-limit rotation speed, determines the maximum one of the recording speeds specified in the apparatus and supported by the disk recording medium for each zone, sets a zone CLV table, and stores the table in a RAM (102). Then, the recording speeds are changed at zone boundaries according to the zone CLV table set based on the upper-limit rotation speeds calculated from the eccentricities.

Abstract: The engine drives the generator, which generates electric power. The power drives the compressor. Thus driven, the compressor cools the interior of the refrigerating chamber. When the engine stops, the output of the generator stops is no longer available. Then, the compressor is automatically driven by the power of the storage battery unit.
