    摘要: An electronic apparatus has a first housing, a second housing, and speakers. The first housing and second housing are so coupled as to be movable between a first position away from each other and a second position in which one of them is laid on the other. The speaker is provided in the first housing. A first opening is situated at a place covered over the second housing when it is in the second position and corresponding to the speaker. A second opening is located on the second housing at a place corresponding to the first opening when the second housing is in the second position. A third opening is provided in the second housing situated on the outer side at the second position and communicates with the second opening.

    摘要: An aromatic-aliphatic copolycarbonate and a process for producing the same which comprises polycondensation of an aromatic dihydroxy compound, such as 1,1-bis(4-hydroxyphenyl)cyclohexane, tricyclo(5.2.1.02,6)decanedimethanol, and a carbonic acid diester in a molten state under heating, wherein the carbonic acid diester has a chlorine content of 20 ppm or lower. The copolycarbonate has improved refractive index, balance of dispersion, and photoelastic constant while retaining high impact resistance, high heat resistance, and excellent hue.
