    摘要： Disclosed are silica-filled rubber granules comprised of a cocoagulation product of rubber and silica, which are extremely less powdery and excellent in handling and kneading, as well as an industrially advantageous process for producing same. The silica-filled rubber granules of the present invention are dried granules of a cocoagulation product of rubber and silica particles, which are characterized in that an average particle diameter (D50) in terms of the sieve analysis is 300˜3000 μm and the weight ratio of the granules within the range of D50±(D50×0.5) is at least 50% by weight. The silica-filled rubber granules are produced by supplying a cake of a cocoagulation product of silica and rubber having a water content of 40˜80% by weight to a drier provided with an indirect-heating type container having stirring wing blades, and then drying the cake while stirring it with the stirring wing blade.

    摘要： A pen type electronic digital calculator in which keys are arranged in three rows on one half part of the tubular body in its lengthwise direction and when the three rows of keys are held substantially horizontal, the top surface of each key of the central row is higher than the top surfaces of the keys of the other rows. The keys of the respective rows are mounted so that they are longitudinally spaced from the keys of adjacent rows, and each key is disposed at the center of a recess formed in the tubular body.
