    • A free curved surface precision machining tool for precision-machining a surface to be machined with the lower end in contact therewith by rotation around an axis x. It includes a drum-shaped tool having a rotation axis x orthogonal to the axis z and rotationally driven around the rotation axis x. This drum-shaped tool has a convex machining surface in the form of an arcuate rotary body obtained by rotating an arc of a radius r with the center at the intersection O between the axis z and the rotation axis x around the rotation axis x. The convex machining surface contacts the surface to be machined to precision-machine the latter, while the convex machining surface is rotated around the orthogonal axis x so as to disperse the machining position of the convex machining surface.
    • 一种自由的曲面精密加工工具,用于通过围绕轴线x的旋转来精确加工待加工表面的下端与其接触。 它包括具有与轴z正交的旋转轴线x并围绕旋转轴线x旋转地驱动的鼓形工具。 这种鼓形工具具有通过在轴线z和旋转轴线x之间的交点O处围绕旋转轴线x旋转半径为r的半径r的圆弧而获得的弓形旋转体的凸形加工表面。 凸面加工面与被加工面接触,对后者进行精密加工,同时凸面加工面绕正交轴线x旋转,从而分散凸面加工面的加工位置。

    • A self-luminescent light source for a liquid crystal display watch characterized by comprising a fluorescent substance layer which has a light reflectivity and which contains a radioactive substance in at least a part thereof, a reflective layer which is disposed on one surface of the fluorescent substance layer and which serves to reflect and scatter fluorescence from the fluorescent substance layer, a case which is disposed on the side of the reflective layer remote from the fluorescent substance layer and which serves to perform shielding from radiation given out from the radioactive substance, and a cover which is disposed on the side of the fluorescent substance layer remote from the reflective layer and which serves to absorb the radiation given out from the radioactive substance and to transmit the light from the fluorescent substance layer.
