Abstract: The invention relates to a harmonic drive (12) which can be provided with overload protection that is easy to influence constructionally and a free-wheeling characteristic. To this end, the spokes (21) of the internal geared wheel (15) are specifically deformable depending on the torque or the direction of rotation. The spoke shafts (22) are divided crosswise to the drive axis (24) or in a radial direction in relation thereto. This division (45) is bridged over flexibly in the peripheral direction of the internal geared wheel so that the effective radial length of the spoke may be reduced in the presence of the appropriate bending stress by buckling the shaft, in order to then eliminate the local toothing contact between the internal geared wheel edges (13) and the outer support ring (11) in the extension of the spoke. The bridging of the spoke division can be configured differently for the two directions of rotation in order to obtain different response characteristics, up to direction-dependent free-wheeling characteristics e.g. in the event of a considerably unsymmetrical spoke shaft course in relation to the radials.

Abstract: <P>PROBLEM TO BE SOLVED: To precisely demodulate regenerated data of a card.  <P>SOLUTION: A regeneration signal of the card data is binarized and taken as 1F and 2F data, and the time value of the 1F and 2F data are sequentially stored in a RAM 13. The time value stored in the RAM is sequentially taken out, and decision whether 1F or 2F is made according to the reference value. Demodulation processing depending on the decision result is performed, and according to the processing result, the data of the RAM is rewritten. As a result, the center of the regeneration signal of the 2F data is dragged to the regeneration signal side of the 1F data due to the adjacent recording of the 1F and 2F data in the card. By this phenomenon, precisely data can be demodulated even in the case where the 2F data regenerated from the card is longer than the time value of the actual 2F data and the 1F data regenerated from the card is shorter than the time value of the actual 1F data.  <P>COPYRIGHT: (C)2003,JPO
