摘要： A multifocal lens (10) for eyeglasses, provided with portions of different indexes, such as for far vision and near vision. The multifocal lens is given a predetermined degree of addition Add by making the difference between an average refractive index D11 of the far vision portion (11) and an average refractive index D12 of the near vision portion (12) on the outside (2) of the lens numerically smaller than the degree of addition Add, and by adjusting an average refractive index D21 of the far vision portion and an average refractive index D22 of the near vision portion on the inside (3). The average refractive indexes D11 and D12 of the outside (2) can be so adjusted as to reduce the difference in magnification between the portions for far vision and near vision. The difference between the average refractive indexes D11 and D12 of the outside (2) can also be reduced. Thus, it is possible to provide a multifocal lens which has less image fluctuation or distortion, as might otherwise be caused by the magnification difference, and which can provide comfort with improved astigmatism, widen a range of distinct vision and reduce the image fluctuation.

摘要： This invention aims at reducing astigmatism, securing uniform refraction power, preventing irregular reflection due to existence of a plurality of refraction planes, and reducing the size of a lens system in a variable focus type visual power correction apparatus in which a plurality of optical lenses are superposed in such a manner that main meridians thereof are coincident with one another, and refraction power of which changes upon relative sliding motion in the direction of the plane of superposition along the meridians. The magnitude of astigmatism of the lens as a single substance constituting the variable focus type visual power correction apparatus is set so that when the magnitude is expressed by contour lines having an arbitrary dioptry gap, each contour line is substantially parallel to the meridian and describes a straight line, and the magnitude of refraction power is substantially rectangular to the meridian and describes a straight line. This structure can eliminate astigmatism, the refraction power in the region where the eyeglass lenses superpose with one another becomes constant and an eyeglass lens having optical performance equivalent to that of a mono-focal lens can be obtained.

摘要： A gradient index multifocal lens suitable for compensation for presbyopia, which has a gradient index plane inside, rather than outside as conventional. Since the lens can have the outer surface with a constant base curve, the variations in magnification caused by the shape factor can be prevented and the difference in magnification between near vision and far vision can be reduced. In addition, the variations in magnification in the gradient index plane can be suppressed. Therefore, this lens can reduce the shaking and distortion of images caused by the difference in magnification and can give a comfortable field of view. In addition, even when a lens for correcting astigmatism is made by using this multifocal lens, the lens can reduce the shaking and distortion of images, because the gradient index surface can be combined with a toric surface for correcting astigmatism on the eye-side surface.
摘要翻译：一种适用于老花眼补偿的渐变折射多焦点透镜，其具有内部的梯度折射面，而不是常规的外部。由于透镜可以具有恒定的基本曲线的外表面，所以可以防止由形状因子引起的放大变化，并且可以减小近视力和远视力之间的放大率差异。此外，可以抑制梯度折射率平面中的放大倍率的变化。因此，这种镜头可以减少由于放大倍数引起的图像抖动和失真，并且可以给人以舒适的视野。此外，即使通过使用该多焦点透镜进行用于校正像散的透镜，透镜也可以减少图像的抖动和变形，因为梯度折射率表面可以与用于校正眼侧表面上的像散的复曲面合并。

摘要： In a process of determining the shape of a surface of a graded multifocal lens used as a lens of glasses, the radii of curvature of main points on the lens are calculated, the surface of the lens is divided into a plurality of lattice sections, and the shape of each section of the surface is determined by using a curved surface equation of a bicubic expression. The coefficients of the bicubic expressions are determined by using a condition that the derivative of second order of the curved surface expression expressing an adjacent section at the boundary is continuous. Accordingly, the shapes of the surfaces of the sections which are obtained by the curved surface expressions are continuous and smooth. Since the shape of the curved surface of each section can be determined by calculation, the shape of the surface can be partially corrected easily if necessary. Consequently, a graded multifocal lens having a smooth aberration curve and a wide region of distinct vision, meeting various specifications, can be provided and a lens for glasses which has a comfortable field of vision can be provided.

摘要： A PD (81) is positioned at a predetermined position on an optical table, the rotation of a resist master (110) is stopped, a focusing laser (73) is driven, and a head (77) is positioned in a proper position by a head slider control circuit (101). The master (110) is turned, a focusing servo circuit (103) is started and, the PD (81) is moved horizontally by a focus fine adjustment circuit (99) by a minute distance corresponding to an estimated adequate focus position data. Since the difference between voltage signals from the two output terminals of the PD (81) is varied because of the surface vibration and minute movement caused by the rotation of the master (110), a differential amplifier (103a) moves a recording lens (77a) vertically by a distance of several microns so as to make an error signal zero. Numerical information on a digital display (93) at this time is compared with the focus position data. When both of them agree with each other, the focus position data is employed as an adequate focus position data and used for the initial setting of the adequate focus position. When they do not agree with each other, the numerical information is employed as the adequate focus position data and the focus position data is rewritten. By using the numerical adequate focus position data, the inital setting of the adequate focus position matching the type of the resist master can be carried out easily.

摘要： An inexpensive small-sized PLL (phase-locked loop) oscillator for use as the clock source of a computer, etc., which can output such a high frequency about 40 MHz that is difficult to obtain from a fundamental-based crystal oscillator. The oscillator operates as stably as the fundamental-based crystal oscillator does, is easy to set a frequency, can be produced in a short lead time, and can be easily handled like the conventional crystal oscillator. The PLL oscillator is housed in a package, which contains a piezoelectric vibrator, an oscillation circuit for driving the vibrator, and a PLL circuit which receives a reference signal from the oscillation circuit. The output frequency of the PLL oscillator is determined by the oscillation frequency of the oscillation circuit and the scaling factor of the programmable divider of the PLL circuit so that a prescribed output frequency can be obtained by selecting the corresponding scaling factor, which may be stored in a programmable read-only memory.

摘要： A piezoelectric vibrator so assembled that a space may be formed between a vibrating piece and a plug, with a conductive resin-made connection layer being formed for connecting, to the vibrating piece, a slab-like lead which has its top end opened in a U-shaped form. The top end of the lead can absorb shock due to its elasticity. Before forming the connection layer, a temporary fastening layer is formed between the top end of the lead and the vibrating piece using UV curing resin, or silver paste is applied to either the top end or the vibrating piece to increase the workability. By this method, piezoelectric vibrator units, which have a high resistance to shock and have a little change in frequency when being left in a high temperature environment and which are very reliable, can be mass-produced at low cost.
