  • Patent number: 8986874
    Abstract: A wound electrode body is fabricated by laminating and winding positive and negative electrode sheets together with a separator therebetween for insulation. On both positive and negative electrode side ends of the wound electrode body, laminates of current-collecting foil layered portions of the electrode sheets are bent or folded f toward the outer peripheral side to be separated into two. The separated laminates and forked connector leaves are overlapped and clamped between an ultrasonic chip and an anvil. Then, they are welded. The forked connector leaves are arranged such that no opposing forked connector leaf is present in the direction of a line normal to the forked connector leaf, so that the anvil does not have to be cantilevered. This allows welding by using the ultrasonic chip and the anvil without interfering with the collector rs. As a result, the quality of welding is improved.

  • Patent number: 5900108
    Abstract: An arm (10c) of a manual lever (10) is formed with a pushing portion (10f). A ratchet pawl (17) making reciprocal movement in synchronization with the manual lever (10) is formed with a resilient portion (17a) to be pushed by the pushing portion (10f) and a pawl portion (17b) which makes contact with a tooth of the ratchet wheel (19). A printer (P) is disposed at tip ends of the arms (10c, 10d). The ratchet wheel (19) is integral with the transfer drum (18). In the step of gripping the manual lever (10), the resilient portion (17a) is made to deform, and the pawl portion (27b) makes slide movement toward a tip end of a tooth. At the moment when the pawl portion (17b) gets over the tip end of a tooth, a resistive force against the manual lever (10) is significantly reduced, and as a result, the printer (P) makes impact contact with a label and prints marks on the label. When the label tape (12) is to set, the bottom cover (14) is made open.

  • Patent number: 5619916
    Abstract: A printer comprising printing type belts 16 and 16' having printing types 16b and 16b' as well as indicating types 16d and 16d', and setting wheels 7 and 7' for turning the printing type belts, and configured to limit the turnings of the printing type belts for preventing the indicating types from being fouled, and to allow the setting wheels to rotate idly for preventing breakage of the printer itself after the printing type belts have reached rotation-limited positions. The rotation-limited position is determined by a pair of convexities 16e and 16f or 16e' and 16f' formed on each of the printing type belts and edges 4a and 5a or 4a' and 5a' of display window frames 4 and 5 or 4' and 5'. The setting wheels are allowed to rotate idly by recesses which are formed in the printing type belts so as to be engaged with teeth 7b and 7b' of the setting wheels, and configured so as to have slanted surfaces 16h and 16h' rising from sides near the convexities toward sides far from the convexities.
