Abstract: The present invention relates to a coloring composition for preventing see-through of cloth which comprises, on the basis of the total mass of the composition, a pigment in an amount ranging from 0.002% by mass to 1% by mass; a polymer particulate dispersion; and water. The present invention can thus provide the cloth which can prevent any see-through of the color of the underlying layer without causing any color-see-through phenomenon even if the cloth is white or light-colored one, and which can show excellent fastness while maintaining hand and feel peculiar to the original cloth irrespective of the material of the cloth used.

Abstract: A pneumatic tire production system comprises production lines each including a green tire building station for assembling unvulcanized members of pneumatic tires into green tires. The green tires are vulcanized at a vulcanizing station which includes at least one vulcanizing unit equipped with a plurality of vulcanizing molds. The number of the vulcanizing mold is determined so as to satisfy the vulcanizing capacity which is substantially equivalent to the number of green tires formed at the building station within a predetermined unit time. The system serves to minimize the intermediate stock amount of green tires due to minimized changeover between different types of tires to be alternately produced.

Abstract: In a ballpoint pen which is formed to have an ink-consumption value per unit area of 0.64 to 1.6 mg/cm2, the surface tension of the ink for the ball point pen is adjusted to a range of 16 to 32 mN/m so that blotting, line splitting and the like hardly occur, that the ink transferred onto the paper surface is ready to be dried and that fluctuation in the density and width of the written lines are less likely to occur due to a storage environment and to a writing condition.

Abstract: In a ball pen which is formed to have an ink-consumption value per unit area of 0.64 to 1.6 mg/cm2, the water content is adjusted in the range from 30.0 to 80.0 wt %, the content of a volatilization-inhibiting substance in the range from 0.1 to 10.0 wt % and the content of a hardly-volatile water-soluble liquid medium in the range from 1.0 to 40.0 wt % in the ink for a ball pen in order to achieve both the quick-drying property of the ink transferred onto the paper surface and the non-drying property of the point of the pen-tip and further a good writing feeling.
