    • The present invention provides a series of aspherical contact lenses, each lens having a first central optical zone on its anterior surface and a second central optical zone on its posterior surface. Both central optical zones are aspherical surfaces. The first central optical zone is designed to have a surface which provides a target optical power and an optical power profile selected from the group consisting of (1) a substantially constant optical power profile, (2) a power profile mimicking the optical power profile of a spherical lens with an identical targeted optical power, and (3) a power profile in which lens spherical aberration at 6 mm diameter is from about 0.65 diopter to about 1.8 diopters more negative than spherical aberration at 4 mm diameter.
    • 本发明提供了一系列非球面隐形眼镜,每个透镜在其前表面上具有第一中心光学区,在其后表面上具有第二中心光学区。 两个中心光学区都是非球面。 第一中心光学区被设计成具有提供目标光功率的表面和从以下组成的组中选择的光功率曲线:(1)基本上恒定的光功率曲线,(2)模拟光功率曲线的功率曲线 具有相同目标光焦度的球面透镜,以及(3)直径为6mm的透镜球面像差为约0.65屈光度至约1.8屈光度的功率分布,其直径比直径为球面像差更负。

    • Molding equipment for an injection molding machine and particularly adapted for ejection of a molded article from a mold core. Mold cores borne by a rotatable turret are brought into position in respective cavities formed in one or more mold halves. The turret and mold halves are so configured that when one core is in registration with the cavity of that mold half, another core carrying a previously molded article is positioned away from the mold halves for ejection of the article. The equipment includes an ejector having cooperating, molded article-engaging portions, at least one of the portions being moveable in a first direction to close upon another portion of the ejector to encounter the molded article, and the ejector portions, when closed, being moveable in a second, different direction to expel the molded articles from the cores upon which they were molded.
    • 用于注射成型机的成型设备,特别适于将模制品从模芯中排出。 由可旋转的转台承载的模芯在一个或多个半模中形成的相应空腔中被置于适当位置。 转塔和半模的结构使得当一个芯体与该半模的腔体对准时,承载预先模制的物品的另一个芯线定位成远离模具半部分以排出物品。 所述设备包括具有配合的成型品接合部分的喷射器,所述部分中的至少一个可在第一方向上移动以在所述喷射器的另一部分上相对于所述模制品相接近,并且所述喷射器部分在关闭时可移动 在第二个不同的方向上,将模制品从它们被模制的芯上排出。
