    • Processes for producing an aromatic/aliphatic copolycarbonate which has excellent impact resistance, excellent heat resistance, a high Abbe's number, a low photoelastic coefficient, and an excellent color tone. The processes include those in which: an aromatic/aliphatic copolycarbonate having a nitrogen content of 9 ppm or lower is produced from an aliphatic dihydroxy compound having a nitrogen content of 10 ppm or lower; an aromatic/aliphatic copolycarbonate is produced from an aliphatic dihydroxy compound having an iron content of 1 ppm or lower; an aromatic/aliphatic copolycarbonate is produced from an aliphatic dihydroxy compound having a content of aldehyde groups and/or formyl groups of 100 ppm or lower; an aromatic/aliphatic copolycarbonate is produced by subjecting an aromatic dihydroxy compound and an aliphatic dihydroxy compound having a content of free chlorine of 5 ppm or lower to polycondensation with heating and melting; and an aromatic/aliphatic copolycarbonate is produced from an aliphatic dihydroxy compound which has a melt Hazen unit of 40 or smaller after having been maintained at 260° C. for 5 hours in the air.
    • 具有优异的耐冲击性,优异的耐热性,高的阿贝数,低光弹性系数和优异的色调的芳香族/脂肪族共聚碳酸酯的制造方法。 该方法包括:由氮含量为10ppm以下的脂肪族二羟基化合物制造氮含量为9ppm以下的芳香族/脂肪族共聚碳酸酯的方法; 由铁含量为1ppm以下的脂肪族二羟基化合物制造芳香族/脂肪族共聚碳酸酯, 由具有100ppm以下的醛基和/或甲酰基含量的脂肪族二羟基化合物制造芳香族/脂肪族共聚碳酸酯; 通过使芳族二羟基化合物和游离氯含量为5ppm以下的脂肪族二羟基化合物进行加热熔融缩聚来制造芳香族/脂肪族共聚碳酸酯, 芳香族/脂肪族共聚碳酸酯由脂肪族二羟基化合物制成,在空气中保持260℃,熔融Hazen单位为40以上。

    • An object of the present invention is to provide a battery box which can prevent a dry battery from being inserted in the battery box in an erroneous mode and thus avoid a short-circuit condition of the dry battery. To prevent a lateral face of the dry battery to be inserted in the battery box from coming into contact with an electrode terminal, a contact preventing member which functions as a stopper is provided above at least one of a positive electrode terminal or a negative electrode terminal. In case that the contact preventing member protrudes upwardly over the battery box, a lid of the battery box is provided with a through hole, so as to avoid an interference of the contact preventing member with the lid when the lid is closed. Also, it is possible to design the lid without any through holes, by forming the contact preventing member as a protrusion.
    • 本发明的目的是提供一种电池盒,其可以防止干电池以错误的方式插入电池盒中,从而避免干电池的短路状况。 为了防止干电池的侧面插入到电池盒中与电极端子接触,在正电极端子或负电极端子中的至少一个上方设置用作止动件的防止接触件 。 在接触防止构件向上突出于电池盒的情况下,电池盒的盖设置有通孔,以便在盖关闭时避免接触防止构件与盖的干涉。 而且,可以通过将防止接触构件形成为突起而设计没有任何通孔的盖。
