Abstract: PURPOSE:To enable the spectacle frame which can be folded thin by arranging a left and a right temple flatly without putting them one over the other, and constituting end parts of the temples along the curved surfaces of lenses as much as possible while regarding the length directions of the temples as axes. CONSTITUTION:While the left and right temples 1 and 7 are folded so as to store the spectacles, the temples 1 and 7 are on nearly the same plane at a distance and not put one over the other. Namely, a leftside hinge 2 and a right- side hinge 6 are fitted by inclining their axes asymmetrically in the left-right direction. The left-side temple 1 between the temples 1 and 7 which are opened is folded by almost 90 deg., and then the temples are stored at the slanting angle of the left-side hinge axis by the constitution of the left-side hinge 2. In this case, the end part is slanted to the front about the length direction of the temple 1 as the axis so that the temple end part is along the curved surface of the lens as much as possible. Further, when the right-side temple 7 in the open state is folded by almost 90 deg., the length direction of the right-side temple 7 is stored horizontally.

Filed: 1986-07-21
Abstract: PURPOSE:To improve the accuracy of plate thickness detection by reflecting the result of comparison between measured plate thickness value data and actual mean plate thickness value data on next measurement successively. CONSTITUTION:The inner periphery L1 and outer periphery L2 of a coil are found firstly. Then, the internal diameter d1 and external diameter d2 of the coil are found from d1=L1/2pi and d2=L2/2pi and mean plate thickness hA is found from hA=(d2-d1)/nXgamma (where gamma is an occupation rate and (n) is the number of turns of a coil). Here, when the mean value of the measured plate thickness detected by a plate thickness gauge is denoted as hX, a plate thickness rate eta is hA/hX. This is used as a coefficient of learning correction by primary smoothing and then a new coefficient of learning correction is found successively from an equation II. Then, a correction multiplier alphaT found from an equation I is corrected with the coefficient of learning correction found as mentioned above. Then, a multiplier alphaS calculated from an equation III correct the measurement relational equation of the plate thickness gauge successively with the control correction command signal of an arithmetic and control unit. Consequently, the detection accuracy of the plate thickness can be improved.
