  • Publication number: 20240102538
    Abstract: [Problem] To provide a swing-type speed reducer that has a large crossing angle, and that can be further miniaturized compared to conventional speed reducers. [Solution] Provided is a swing-type speed reducer 1 comprising: a main body 10; an input shaft 20 that is rotatably held in the main body 10; a precession body 30 that precesses; a swinging body 40 that engages with the precession body 30 and is swung by the precession; and an output shaft 50 that is rotated by the swing of the swinging body 40. In the present invention, a precession annular groove 34 for precession of the precession body 30 and a swinging annular groove 33 for swinging the swinging body 40 are provided on the surface of a spherical portion 31. Thereby, in comparison to a conventional case where the grooves are provided on the inner peripheral surface of a member, the region where the grooves can be machined is increased, and the device can be further miniaturized.

  • Patent number: RE42571
    Abstract: An input image signal is coded by an encoder to be outputted as a basic code string, and the basic code string is delayed by a code-string delay circuit for a predetermined period of time to be outputted as an additional code string. The basic code string is synthesized with the additional code string by a code-string synthesizer to be outputted as an output code string. Thus, there is provided an image data coding system which can quickly restore data even if the data is lost due to error and in which the increased code amount is less than the cycle refresh and the error correction.
