    • Provided is an inorganic-particle-dispersed sputtering target in which inorganic particles are dispersed in a Co base material, wherein the inorganic particles have an electric resistivity of 1×101 Ω·m or less and the volume ratio of the inorganic particles in the target is 50% or less. The sputtering target thus adjusted is advantageous in that, when sputtering is performed using a magnetron sputtering device comprising a DC power source, the inorganic particles are less charged, and arcing occurs less frequently. Accordingly, by using the sputtering target of the present invention, the occurrence of particles attributable to the arcing reduces, and a significant effect of improving the yield in forming a thin film is obtained.
    • 本发明提供一种无机粒子分散溅射靶,其中无机颗粒分散在Co基材料中,其中无机颗粒的电阻率为1×10 11Ω·m·m·m以下,无机颗粒的体积比 目标是50%以下。 如此调整的溅射靶的优点在于,当使用包括直流电源的磁控管溅射装置进行溅射时,无机颗粒的带电少,并且电弧放电频率较低。 因此,通过使用本发明的溅射靶,可以减少由于电弧引起的粒子的发生,并且获得提高薄膜形成的显着效果。

    • A first object of the present invention is to provide a rubber composition which improves both wear resistance and low heat-buildup property, and a second object is to provide a tire in which low heat-buildup property (low fuel consumption) and tear resistance are improved without impairing wear resistance. In order to achieve the first object, a first aspect of the present invention is a rubber composition comprising a rubber component selected from at least one of natural rubber and a diene-based synthetic rubber, and a carbon black. The carbon black has a dibutyl phthalate absorption amount (DBP) of 140 to 200 ml/ 100 g. An aggregate of the carbon black has a ratio (Dw/Dn) of weight average diameter (Dw) to number average diameter (Dn) of 1.80 to 2.40, and the carbon black has a specific tinting strength (Tint) satisfying an inequality: Tint ≧0.100× nitrogen absorption specific surface area (N2SA)+93. In order to achieve the second object, a second aspect of the present invention is a tire which has at least a tread, and the tread is made of the rubber composition of the first aspect of the invention.
