A stitch tightening device of a ball stitching machine comprises a ball stitching table having at least one clamping tool and a stitch tightening unit for tightening a thread to be assembled to a ball. In the nonvolatile memory section, a transistor having an extremely low off-state current allows a data signal to be held in the capacitor for a long period of time. The connector has an open circuit inner stub where the inner conductor of the transmission line couples to the inner conductor of the connector, or an open circuit outer stub where the outer conductor of the transmission line couples to the outer body of the connector, or both. The digital baseband inphase signal and the digital baseband quadrature phase signal are carried in zero frequency. For binary content-addressable memories and ternary content-addressable memory, one or more error detection bits are used per entry to prevent or at least reduce the possibility of a lookup error. This composition contains an extract of at least one Chamomilla plant andor of at least one Achillea plant.
