Patent number: 6719658Abstract: A simple planetary gear mechanism is provided with an automatic alignment function to support the planet gear to obtain a speed reducer having reduced backlash by a simple method. A planet gear is supported by a carrier pin that is in turn supported by a carrier. The carrier pin includes a crank portion that is eccentric by “e” relative to the axis center of the carrier pin with the eccentric angle being made variable. The planet gear is supported rotatably about the axis center of the crank portion. Consequently, with the eccentric angle being made variable, the axis center of the planet gear is automatically aligned in the radial direction upon assembly of each gear, thereby making it possible to minimize backlash only by incorporating a sun gear having a proper dimension.Type: GrantFiled: December 21, 2001Date of Patent: April 13, 2004Assignee: Sumitomo Heavy Industries, Ltd.Inventors: Takashi Haga, Sueo Fukaya, Takashi Hatanaka

Patent number: 6637880Abstract: An eyeglass having a prescription face optimized considering the individual wearing conditions, and a method for manufacturing the eyeglass. Information including the prescribed values including data relate to the VR value of each eyeglass wearer necessary to design and manufacture the eyeglass are transmitted through a terminal installed in an optician (on the orderer's side) to a host computer installed in an eyeglass manufacturer (on the manufacturer's side). The information is processed by the host computer to determine the eyeglass shape optimized on the basis of an optical model under simulated wearing conditions and to determine the manufacturing conditions. Thus, an eyeglass is manufactured by a numerical controlled machine and an edger and is delivered to the orderer's side.Type: GrantFiled: December 4, 2000Date of Patent: October 28, 2003Assignee: Hoya CorporationInventors: Tetsuma Yamakaji, Takashi Hatanaka
