  • Method for automatically grinding lenses
    Patent number: 4217736
    Abstract: An improved automatic lens grinding machine and process for shaping lenses to fit any particular glasses frame.The machine includes a recording assembly by which the pattern of a glasses frame which will hold a lens is recorded on a heat or photosensitive substrate. The paper and lens are mounted on a carriage assembly which is movable into and out of a grinding position adjacent a grinding assembly. When positioned in the grinding position, grinding is under control of a scanner assembly and a control circuit.
    Type: Grant
    Filed: September 30, 1977
    Date of Patent: August 19, 1980
    Assignee: Kabushiki Kaisha Hoya Lens
    Inventors: Hayao Akaba, Akira Ikeda, Masayoshi Lee

  • Servo system for finishing objects materials
    Patent number: 3978386
    Abstract: A servo system to permit the lens finishing for example, corresponding to a registered pattern and permit such finishing at desired pressure, etc. for the conveniences of the easy and effective grinding and finishing, in a manner that the detectors supply to the lower and upper limit voltage comparators the detectors outputs, which are then supplied to the logic circuits as well as the outputs for the servo-driving and the outputs from flip-flops, so that the servo motor rotates in normal and/or reverse directions.
