  • Patent number: 11959539
    Abstract: It is included an internal gear (2), an external gear (3) having flexibility, and a wave generator (4) that forms a meshing part (P) with the internal gear (2) in the external gear (3) and moves the meshing part (P) in a circumferential direction of the internal gear (2). The wave generator (4) is configured such that the meshing part (P) is formed at three or more positions in a circumferential direction of the external gear (3). A value (DpF/ZF) obtained by dividing a working pitch diameter DpF of the external gear (3) by the number of teeth ZF is greater than a value (DpR/ZR) obtained by dividing a working pitch diameter DpR of the internal gear (2) by the number of teeth ZR.
    Type: Grant

  • Publication number: 20020059057
    Abstract: A sound reproducing device that displays character information in languages corresponding to a user's wishes without increasing a burden on the user. The user sets an order of priority of the languages in which the character information is displayed when a CD is reproduced. For example, a code “69” (=Japanese) is set as a first priority. Then, when the CD is reproduced, based on the order of priority set in advance, the character information represented by the language with the highest priority among the character information recorded on the CD is displayed on a LCD (19). By setting the order of priority in advance, there is no longer any need of setting at each reproduction of the CD and the character information is displayed on the LCD (19) in the languages desired by the user.
