    Abstract: A safety shackle includes a U-shaped shackle body and a bolt shaft. Two ends of the opening of said shackle body are each provided with a screw hole, and the front end of the bolt shaft is reached the screw hole at one end of the shackle body and screwed into the screw hole at the other end thereof. The screw size of the screw holes cooperates with that of the bolt shaft. Preferably, said bolt shaft is a regular bolt. The frond end (L5) and the rear end (L6) of said bolt shaft have the same screw size. Alternatively, the screw size of the frond end is less than that of the rear end. Further, the length (L4) of the bolt shaft is equal to or less than the outside width (L3) of the two ends of the opening of said shackle body. With the invention, the bolt shaft would not fall off even if the screw at one end get loose or the bolt shaft breaks at its center, so as to make the connection safer and more reliable.

    Abstract: A realizing method for supporting relay in a cellular system comprises: selecting the link transmission order of a frame structure, including the transmission order of a downlink relay link, a downlink access link, a uplink access link and uplink relay link; determining the guarding intervals of the uplink-downlink transition point in the frame structure in the selected link transmission order, so that when uplink-downlink transiting the uplink-downlink interference is minimal; transmitting and receiving according to the selected link transmission order and the determined guarding intervals. A realizing apparatus uses the method. The presentinvention could realize relay in a cellular system and avoid uplink-downlink interference.

    Abstract: 本发明适用于锂离子电池生产工艺技术领域,提供了一种锂离子电池、锂离子电池芯及其制作方法。其中的锂离子电池芯包括多个单片状第一极性片以及一卷绕式第二极性隔膜条袋,多个单片状第一极性片分别相互对齐排布于卷绕式第二极性隔膜条袋的相邻卷绕层间隔中;卷绕式第二极性隔膜条袋包括顺次叠放的第一隔膜、带状第二极性片以及第二隔膜,且第一极性与第二极性不相同。本发明的锂离子电池芯结合了卷绕式和叠片式的优点,相对于现有技术,其在制作过程中只需对第一极性片进行冲切,而无需对带状第二极性片进行冲切,从而大幅减少了冲切过程中极性敷料的脱落,降低了由此导致的产品不良率,且降低了极片的对齐精度控制难度,提高了产品的生产效率。
