Abstract: A battery terminal includes: a main body unit; a penetration member that is arranged in a manner extending from an end side of the main body unit to the other end side of the main body unit across slits along a tightening direction Y, includes an abutting portion formed in the end side, and has a threaded hole and a taper forming end portion provided with first tapered surfaces formed in the other end side; a fastening member threadedly engaged with the threaded hole; and a pressing force converting member that converts fastening force in an axial direction X generated between the fastening member and the penetration member with rotation of the fastening member around the axial direction X into pressing force in the tightening direction Y pressing the main body unit between the abutting portion and the pressing force converting member along the tightening direction Y.

Abstract: The bolt of the present invention can reliably peel coating even when fastened with a low torque, and can secure sufficient conductivity. A coating peeling part for peeling coating is formed at a tip end of an axis part in which a regular screw part is formed. The coating peeling part includes crushing parts having a trapezoidal top part and having a flank which is projected at a different angle with respect to the flank of the regular screw part; and a protruding part which is arranged adjacent to the crushing parts and whose top part projects beyond the outer diameter of the regular screw part.

Abstract: The bolt of the present invention can reliably peel coating even when fastened with a low torque, and can secure sufficient conductivity. A coating peeling part 4 for peeling coating is formed at a tip end of an axis part 2 in which a regular screw part 1 is formed. The coating peeling part 4 includes crushing parts 5 having a trapezoidal top part and having a flank which is projected at a different angle with respect to the flank of the regular screw part 1; and a protruding part 6 which is arranged adjacent to the crushing parts 5 and whose top part projects beyond the outer diameter of the regular screw part 1.

Abstract: A user views contents by a terminal unit at a different place and bit rate in divided times and upon resumption of viewing, and resumed from an end position automatically. A content distribution control server includes a table to record the end position of the content and user ID, content ID and an end position upon interruption of the service. Upon resumption of the service, the end position is retrieved from the table and the content distribution is resumed from the end position. Further, upon resumption of the service, the control server reads in user information (the user position, the terminal unit used, the reproduction software, the bit rate and the like), so that the content distribution service is performed in the condition optimum to user's current utilization environment irrespective of user information used before interruption.
